The '''Merkava''' ([[Hebrew language|Hebrew]]: {{Audio|He-Merkava.ogg|מרכבה}}, "chariot") is a [[main battle tank]] used by the [[Israel Defense Forces]]. The tank began development in 1973 and entered official service in 1979. Four main versions of the tank have been deployed. It was first used extensively in the [[1982 Lebanon War]]. The name "''Merkava''" was derived from the IDF's initial development program name.
 +
 
 +
It is designed for rapid repair of battle damage, survivability, cost-effectiveness and off-road performance. Following the model of contemporary [[Self-propelled artillery|self-propelled howitzer]]s, the turret assembly is located closer to the rear than in most main battle tanks. With the engine in front, this layout is intended to grant additional protection against a frontal attack, especially for the personnel in the main hull, like the driver. It also creates more space in the rear of the tank that allows increased storage capacity, as well as a rear entrance to the main crew compartment allowing easy access under enemy fire. This allows the tank to be used as a platform for medical disembarkation, a forward command and control station, and an [[armoured personnel carrier]]. The rear entrance's clamshell-style doors provide overhead protection when off- and on-loading cargo and personnel.
 +
 
 +
It was reportedly decided shortly before the beginning of the [[2006 Lebanon War]] that the Merkava line would be discontinued within four years.<ref>{{Citation | title = Israeli Merkava tank production to stop within four years | first = Amnon | last = Barzilai | newspaper = Globes | edition = online | accessdate = September 26, 2007}}.</ref> However, on 7 November 2006, [[Haaretz]] reported that an [[General Staff of the Israel Defense Forces|Israeli General Staff]] assessment had ruled of the Merkava Mark IV that "if properly deployed, the tank can provide its crew with better protection than in the past," and deferred the decision on discontinuing the line.<ref>{{cite web|url = http://www.haaretz.com/hasen/spages/784074.html |title=IDF preparing for another conflict by next summer|first=Amir | last =Oren|publisher=Ha'aretz|date=2006-11-07|accessdate=2007-09-29}}</ref> On 16 August 2013, [[Ministry of Defense (Israel)|Israeli Defense Minister]] [[Moshe Ya'alon]] announced the decision to resume production of the Merkava main battle tank for the IDF Armored Corps.<ref>{{Citation | url = http://dmilt.com/index.php?option=com_content&view=article&id=7649:israel-merkava-tank-production-line-re-activated | title = Israel: Merkava tank production line re-activated | newspaper = Defense market intelligence | date = 17 August 2013}}.</ref><ref>{{Citation | newspaper = Business news | url = http://www.upi.com/Business_News/Security-Industry/2013/08/16/Israel-restarts-Merkava-tank-production/UPI-96411376674689/ | title = Israel restarts Merkava tank production | publisher = UPI | date = 16 August 2013}}.</ref>

==Development==
 +
In 1965, Israel's military establishment began research and development on a domestically-produced tank, the "Sabra" <ref>{{Citation | title = Depleted uranium | url = http://www.salem-news.com/articles/may132010/depleted-uranium-dp.php | date = 2010-05-13 | newspaper = Salem news}}.</ref> (not to be confused with [[Sabra (tank)|the later model of the same name now in service]]). Initially, Britain and Israel collaborated to adapt the United Kingdom's [[Chieftain tank]] that had entered [[British Army]] service in 1966.<ref>{{Citation | publisher = History of war | title = Weapons | contribution = Merkava | contribution-url = http://www.historyofwar.org/articles/weapons_merkava.html}}.</ref> However, in 1969, Britain decided not to sell the tank to Israel for political reasons.<ref name = "waronline1">{{cite web | url = http://www.waronline.org/en/IDF/arms/merkava.htm | title= Merkava series |accessdate=2008-07-04 |publisher= War Online}}</ref>
 +
 
 +
[[Israel Tal]], who was serving as a [[brigade commander]] after the [[Suez Crisis]], restarted plans to produce an Israeli-made tank, drawing on lessons from the 1973 [[Yom Kippur War]], in which Israeli forces were outnumbered by those of the [[Middle East]]'s Arab nations.<ref name="waronline1" />
 +
 
 +
By 1974, initial designs were completed and prototypes were built. After a brief set of trials, work began to retool the [[Tel HaShomer]] ordnance depot for full-time development and construction. After the new facilities were completed, the Merkava was announced to the public in the ''International Defense Review'' periodical. The first official images of the tank were then released to the [[United States of America|American]] periodical ''[[Armed Forces Journal]]'' on 4 May 1977. The IDF officially adopted the tank in December 1978. The first Merkava Mk. 1 tanks were supplied to the IDF in April 1979, nearly nine years after the decision to produce the Merkava Mk. 1 tank was taken.
 +
 
 +
==Primary contractors==
 +
The lead organization for system integration of the Merkava's main components is [[Israel Military Industries]] (IMI). The [[Israeli Ordnance Corps]] are responsible for final Merkava assembly. Contributors to the vehicle include:

 +
[[File:Merkava-1-latrun-2.jpg|right|thumb|Merkava Mark I at [[Yad La-Shiryon]].]]
 +
The Mark I, operational since 1979, is the original design created as a result of Israel Tal's decision, and was fabricated and designed for [[mass production]].
 +
The Mark I weighed 63 tonnes and had a {{convert|900|hp}} diesel engine, with a power-to-weight ratio of 14&nbsp;hp/ton. It was armed with the 105 millimeter M68 main gun (a licensed copy of the British [[Royal Ordnance L7]]),<!--Is this relevant? Nothing is said about implications for Merkava: During the tank's initial conception, the [[NATO| North Atlantic Treaty Organisation]] was in the process of [[standardization|standardizing]] all [[NATO#Membership| member nations']] tanks to the 120 millimeter standard. Is that true?--> two [[7.62 mm caliber|7.62 mm machine guns]] for anti-infantry defense,<ref>{{cite web | url= http://www.israeli-weapons.com/weapons/vehicles/tanks/merkava/MerkavaMk1.html | title=Merkava Mk 1 | accessdate=2008-07-04 |publisher=Israeli Weapons}}</ref> and a 60&nbsp;mm [[Mortar (weapon)|mortar]] mounted externally, with its operator not completely protected by the tank's hull.
 +
 
 +
The general design borrows the tracks from the British [[Centurion tank]], which had seen extensive use during the Yom Kippur war.
 +
 
 +
The Merkava was first used in combat during the [[1982 Lebanon War]], where Israel deployed 180 units. Although they were a success, the [[M113 APC]]s that accompanied them were found to have several defects and were withdrawn. Merkavas were converted into makeshift APCs or armored ambulances by taking out the palleted ammunition racks in storage. Ten soldiers or walking wounded could enter and exit through the rear door.
 +
 
 +
After the war, many adjustments and additions were noted and designed, the most important being that the 60&nbsp;mm mortar needed to be installed within the hull and engineered for remote firing—a valuable feature that the Israelis had initially encountered on their [[Centurion tank|Centurion Mk3s]] with their [[British 2 inch mortar|2" Mk.III mortar]].<ref>{{Citation | first1 = Simon | last1 = Dunstan | first2 = Peter | last2 = Sarson | title = Centurion Universal Tank 1943–2003 | year = 2003 | page = 13 | publisher = Osprey | isbn = 978-1-84176-387-3}}.</ref> A shot trap was found beneath the rear of the turret [[wikt:bustle|bustle]], where a well-placed shot could jam the turret completely.

==Overview==
+
The Mark II was first introduced into general service in April 1983 and incorporated numerous small upgrades as a result of the previous year's incursion into Lebanon. The new tank was optimized for [[urban warfare]] and [[low intensity conflict]]s, with a weight and engine no greater than the Mark I.<ref>{{cite web |url= http://www.israeli-weapons.com/weapons/vehicles/tanks/merkava/MerkavaMk2.html |title= Merkava Mk 2 | work = Tanks | accessdate = 2008-07-04 | publisher = Israeli Weapons}}</ref>
The '''Merkava''' (meaning "Chariot", in Hebrew) was the main heavy [[tank]] of the [[Terran Alliance]] and later the [[Terran Hegemony]], with variants of the venerable design in service continually from the late 23rd century until the end of the twenty-sixth century.<ref name="XTRO:PrimIp13"/><ref name="TRO3075p174"/>
+
 
 +
The Mark II used the same 105&nbsp;[[millimeter|mm]] main gun and 7.62&nbsp;mm machine guns as the Mark I, but the 60&nbsp;mm mortar was redesigned during construction to be located within the hull and configured for remote firing to remove the need to expose the operator to enemy small-arms fire. An Israeli-designed automatic transmission and increased fuel storage for increased range was installed on all further Mark IIs. Anti-rocket netting was fitted for increased survivability against infantry equipped with anti-tank rockets. Many minor improvements were made to the [[fire-control system]]. Updated [[meteorology|meteorological sensors]], [[crosswind]] analyzers, and [[thermography|thermographic]] optics and [[image intensifier]]s gave greater visibility and battlefield awareness.
 +
 
 +
Incrementally improved versions of the original Mark II were designated, with many of these tanks still in service today:
 +
* '''Mark IIB''', with thermal optics and unspecified updates to the fire control system.
 +
* '''Mark IIC''', with more armor on the top of the turret to improve protection against attack from the air.
 +
* '''Mark IID''', with modular composite armor on the chassis and turret, allowing rapid replacement of damaged armor.

 +
The Merkava Mark III was introduced in December 1989, and had upgrades to the drivetrain, powertrain, armament, and electronic systems. The most prominent addition was the incorporation of the locally developed [[IMI 120 mm gun]].<ref>{{Citation | url = http://www.janes.com/articles/Janes-Armour-and-Artillery-Upgrades/Israel-Military-Industries-120-mm-smoothbore-tank-gun-MG251-Israel.html | title = Israel Military Industries 120 mm smoothbore tank gun MG251 (Israel) | publisher = Jane's | newspaper = Armour and Artillery Upgrades}}.</ref> This gun and a larger {{convert |1200|hp}} diesel engine increased the total weight of the tank to {{convert |65|t|lbs}}, but the larger engine increased the maximum cruising speed to {{convert |60|km/h|abbr=on}}.<ref>{{cite web | work = Tanks | url = http://www.israeli-weapons.com/weapons/vehicles/tanks/merkava/MerkavaMk3.html |title=Merkava Mk 3 |accessdate = 2008-07-04 |publisher = Israeli Weapons}}</ref>
 +
 
 +
The turret was re-engineered for movement independent of the tank [[chassis]], allowing it to track a target regardless of the tank's movement. Many other improvements were made, including:
 +
* External two-way telephone for secure communications between the tank crew and dismounted infantry,
 +
* Upgraded ammunition storage containers to minimize ammunition [[cooking off|cook-off]],
 +
* Addition of [[laser designator]]s,
 +
* Incorporation of the ''Kasag'' modular armor system, designed for rapid replacement and repair in the battlefield and for quick upgrading as new designs and sophisticated materials become available,
 +
* Creation of the ''Mark IIIB'', with unspecified armor upgrades.
 +
 
 +
====BAZ System====
 +
The 1995 Mark III BAZ (Hebrew acronym for ''ברק זוהר'', ''Barak Zoher'', signifying ''Shining Lightning''<ref>{{Citation | title = Translate | contribution = ברק זוהר | contribution-url = http://translate.google.ch/#iw/en/ברק%20זוהר | publisher = Google}}.</ref>) had many improved and additional systems including:
 +
* Upgraded fire-control system components, from Electro Optics Industries ([[EL-OP]]) and [[Elbit Ltd|Elbit]], provides the tank with the ability to engage moving targets while on the move (an automatic target tracker),
 +
* [[weapons of mass destruction|NBC]] protection systems,
 +
* Locally developed central [[air-conditioning]] system,
 +
* Added improvements in ballistic protection,
 +
* The '''Mark IIID''' has removable modular composite armor on the chassis and turret.
 +
 
 +
====Dor-Dalet====
 +
The last generation of the Mark III class was the Mark IIID ''Dor-Dalet'' (Hebrew: ''Fourth Generation''), which included several components as prototypes to be introduced in the Mark IV.
 +
* Upgraded and strengthened tracks (built by Caterpillar, designed in Israel),
 +
* Installation of the [[Rafael Overhead Weapon Station|R-OWS]].

 +
The Mark IV is the most recent upgrade of the Merkava tank and has been in development since 1999. The upgrade's development was announced in an October 1999 edition of the ''Bamachaneh'' ("At the Camp") military publication. However, new Merkava Mark IIIs continued to be produced until 2003. The first Merkava IVs were in production in limited numbers by the end of 2004.<ref name="Merkava Mk IV breaks cover">{{Citation | contribution-url = http://www.janes.com/events/exhibitions/eurosatory2010/sections/daily/day2/merkava-mk-iv-breaks-cove.shtml | contribution = Merkava Mk IV breaks cover | publisher = Jane’s | first = David | last = Donald | date = 14 June 2010 | title = Euro satory}}.</ref>
 +
 
 +
The model has a new fire-control system, the [[El-Op]] ''Knight Mark 4''. Removable modular armor, from the Merkava Mark IIID, is used on all sides, including the top and a V-shaped belly armor pack for the underside. This modular system is designed to allow for damaged tanks to be rapidly repaired and returned to the field.
 +
 
 +
Tank rounds are stored in individual fire-proof canisters, which reduce the chance of cookoffs in a fire inside the tank. The turret is "dry"; no active rounds are stored in it.
 +
 
 +
Some features, such as hull shaping, exterior non-reflective paints, and shielding for engine heat plumes mixing with air particles to confuse enemy thermal imagers, were carried over from the [[IAI Lavi]] program of the [[Israeli Air Force]] to make the tank harder to spot by heat sensors and radar.
 +
 
 +
The Mark IV includes the larger 120&nbsp;mm main gun of the previous versions, but can fire a wider variety of ammunition, including [[high-explosive anti-tank|HEAT]] and [[sabot]] rounds like the APFSDS [[kinetic energy penetrator]], using an electrical semi-automatic revolving magazine for 10 rounds. It also includes a much larger 12.7&nbsp;mm machine gun for anti-vehicle operations (most commonly used against [[technical (fighting vehicle)|technicals]]).<ref>{{cite web | url = http://www.defense-update.com/directory/merkava4.htm | title = Merkava Mk4 Detailed | publisher =Defense Update}}</ref>
  
==Description==
+
The new fire-control system enables the Merkava to shoot down helicopters such as the Russian [[Mil Mi-24]] and the French [[Aérospatiale Gazelle|Gazelle]], both of which are used by Israel's neighbors.{{Citation needed| date = November 2010}}
The Merkava is an ancient heavy battle tank design that started its service life with the Terran Alliance when the Mk. I first deployed in [[2294]]; after the formation of the Terran Hegemony in the early twenty-fourth century, the Merkava Mk. II became a key component of the [[Hegemony Armed Forces]] armored units<ref name="TRO3075p174"/> from its introduction in [[2384]].<ref name="XTRO:PrimIp13"/> The Merkava, produced by [[Leopard Armor]] of [[Terra]], was deployed as a front line battle tank throughout the [[Age of War]]. The tank gained a kind of symbolic status during its service in the [[Terran Hegemony]] and had seen multiple revisions of its basic design over the course of the three centuries it was in service, with the last version produced by the Hegemony - the Mk VIII - finally ending production after being declared obsolete by the end of the [[Reunification War]] in [[2597]]. By the time it was declared obsolete the Mk. VIII had been in service for over a century, having first been added to the HAF inventory in [[2465]].<ref name="TRO3075p174">''Technical Readout: 3075'', p. 174, "Merkava Mk. VIII Heavy Tank"</ref>
 
  
Perhaps the most important part the Merkava played in history was serving as the opposing force for the first [[BattleMech]], the ''[[Mackie]]'''s live-fire combat trial. Four remote-controlled Merkava Mk VIs were destroyed in such a fashion as to shock the observers, sealing the BattleMech's rise to the position of king of the battlefield.<ref name="TRO3075p174"/>
+
The Mark IV has the Israeli-designed "TSAWS ('''T'''racks, '''S'''prings, '''a'''nd '''W'''heels '''S'''ystem)" [[caterpillar track]] system, called "''Mazkom''" ({{lang-he|מערכת זחלים קפיצים ומרכובים}}) by troops. This system is designed to endure the harsh basalt rock conditions of Lebanon and the Golan Heights with minimal "track-shedding".
  
==Deployment==
+
The tank carries the Israeli [[Elbit Systems]] BMS (Battle Management System; Hebrew: צי"ד), a centralised system that takes data from tracked units and [[Unmanned aerial vehicle|UAV]]s in theater, displays it on color screens, and distributes it in encrypted form to all other units equipped with BMS in a given theater.
The tank was produced by the Terran Alliance and Terran Hegemony until just before the formation of the [[Star League]].  It was retired from front-line service to the Hegemony militias and the surviving vehicles were finally cannibalized for parts - particularly the fusion engine - during the [[Succession Wars]].<ref name="TRO3075p174"/>
 
  
After the discovery of the [[Hegemony Memory Core]], the tank was revised during the first half of the [[Jihad]] due to its simple construction. [[Earthwerks Incorporated]], in the [[Principality of Regulus]], created makeshift factories to produce a new version of the tank, the Mk. IX, on [[Tiber]]. The Regulan government had begun to deploy the Mk. IX to the [[Regulan Hussars]] in large numbers by [[3073]].<ref name="TRO3075p174"/>
+
The Merkava IV has been designed for rapid repair and fast replacement of damaged armour, with the implementation of sections of modular armour that can be easily removed and replaced. It is also designed to be cost-effective in production and maintenance, and as a result its unit cost is lower than for a number of other tanks used by Western armies.
  
==Weapons and Equipment==
+
===Specifications of models===
All of the Merkava's main weaponry is mounted in its turret. The tank's long-range weaponry includes a 15-tube [[Long Range Missile]] Launcher with 16 volleys of fire. The tank's main gun is a Class 5 [[Autocannon]], which was given 20 rounds to feed it. For short-range defense, it has a single 4-tubed [[Short Range Missile]] Launcher with 25 reloads. Finally, for anti-infantry work, the tank sports paired [[machine gun]]s, one mounted on the turret, while  the other is located in the front of the tank.  One hundred rounds are placed with the rest of the ammunition in the main body of the tank.<ref name="TRO3075p174"/>

==Combat history==
 +
[[File:Merkavah Tank of Tzur Maor and his Crew.jpg|thumb|An Israeli Merkava 1 in Lebanon after being hit, 1982]]
 +
The Merkava was used widely during the [[1982 Lebanon War]]. The tank outperformed Syrian tanks (mostly T-62s) and proved largely immune to anti-tank weapons of the time (the AT-3 Sagger and [[RPG-7]]) that were used against it. It was judged to be a significant improvement over Israel's previously most effective main battle tank at that time, the [[Centurion tank]].<ref>{{Citation | title = Armies in Lebanon 1982–84 | first1 = Samuel M | last1 = Katz | first2 = Lee | last2 = Russell | first3 = Ronald | last3 = Volstad | publisher = Osprey | year = 1985}}.</ref> 34 Merkava tanks were lost during war<ref>{{Citation | title = שריון | trans-title = Armor |date=December 2007 | language = Hebrew}}</ref>{{Page needed |date=January 2014}}

In February 2002, a Merkava III was destroyed by a roadside bomb near [[Netzarim]] settlement in the Gaza Strip. The tank was lured into intervening in an attack on a settler convoy. The tank went over a heavy mine, which detonated and totally destroyed the tank. Four soldiers were killed in the blast. This was the first heavy tank to be destroyed during the [[Second Intifada]].<ref>{{cite news | url= http://news.bbc.co.uk/2/hi/middle_east/1821396.stm |title = Israel investigates Gaza tank blast | publisher = BBC | date= 2002-02-15| accessdate= 2011-09-17}}</ref> A second Israeli tank, Merkava II or probably a Merkava III, was destroyed a month later in the same area and a further three soldiers were killed. A third Merkava II or III tank was destroyed near the [[Kissufim Crossing]], when one soldier was killed and two wounded.<ref>{{cite news |url= http://www.mfa.gov.il/MFA/Terrorism-+Obstacle+to+Peace/Palestinian+terror+since+2000/Victims+of+Palestinian+Violence+and+Terrorism+sinc.htm |title =Victims of Palestinian Violence and Terrorism since September 2000 | publisher = MFA | accessdate= 2010-09-17}}</ref>
*;Merkava Mk. VI : The Mark VI was the last of the Merkava's [[ICE|Internal Combustion Engine]] variants. Moving at a top speed of 54 km/h, it used an [[LRM-10]] with a ton of reloads for long range fire support, but the rest of the weapons remained the same. The biggest problem was the armor protection: The Mk. VI only carried four and a half tons of [[BAR]] 7 armor. This led to the tank's rapid destruction after the invention of the [[Large Laser]]. Several Mk. VI's had their LRM launchers removed to produce a remote-control version of the tank which were used to test the prototype ''Mackie'' BattleMech in combat.

During the [[2006 Lebanon War]], five Merkava tanks were destroyed.{{Sfn | Cordesman | Sullivan | 2007 | p = 110}} Only the minority of the tanks used during the war were Merkava Mark IVs, as by 2006 they had still only entered service in limited numbers. [[Hezbollah]] fired over 1,000 anti-tank missiles during the conflict against both tanks and dismounted infantry.{{Sfn | Cordesman | Sullivan | 2007 | p = 110}} Some 45 percent of all tanks and armoured vehicles hit with [[antitank missile]]s during the conflict suffered some form of armour penetration.{{Sfn | Cordesman | Sullivan | 2007 | p = 110}} In total, 15 tank crewmen were killed by these ATGM penetrations.{{Sfn | Cordesman | Sullivan | 2007 | p = 111}} The penetrations were caused by tandem warhead missiles.

After the 2006 war, and as the IDF becomes increasingly involved in unconventional and [[guerrilla warfare]], some analysts say the Merkava is too vulnerable to advanced anti-tank missiles, that in their man-portable types can be fielded by guerrilla warfare opponents.<ref>{{cite web |url=http://video.google.com/videoplay?docid=-8853586453841327363 | title=God’s chariot | accessdate =2008-07-04 |publisher= Aljazeera}}</ref><ref>{{cite news |url=http://news.bbc.co.uk/2/hi/middle_east/4794829.stm | title =Tough lessons for Israeli armour |accessdate=2008-07-04 |publisher=BBC | date=2006-08-15 |first=Jonathan |last=Marcus}}</ref> Other post-war analysts, including David Eshel, disagree, arguing that reports of losses to Merkavas were overstated and that "summing up the performance of Merkava tanks, especially the latest version Merkava Mark IV, most tank crews agree that, in spite of the losses sustained and some major flaws in tactical conduct, the tank proved its mettle in its first high-saturation combat."<ref>{{cite web |url= http://www.defense-update.com/analysis/lebanon_war_3.htm |title=Assessing the performance of Merkava Tanks |publisher= Defense Update}}</ref> On a comparison done by the armor corps newsletter, it was shown that the average number of crewmen killed per tank penetrated was reduced from 2 during the [[Yom Kippur War]] to 1.5 during the [[1982 Lebanon War]] to 1 during the [[2006 Lebanon War]] proving how, even in the face of the improvement in anti-tank weaponry, the Merkava Mark IV provides better protection to its crew (although only a limited number of the Israeli tanks used in 2006 were Merkava Mark IVs). The IDF wanted to increase orders of new Merkava Mark IV tanks, and planned to add the [[Trophy active protection system]] to Merkava Mark IV tanks, and to increase joint training between crews and Israeli [[Anti-tank warfare|antitank]] soldiers.<ref>{{cite web |url = http://www.ynetnews.com/articles/0,7340,L-3439667,00.html | title= IDF mulls spending plan | accessdate = 2008-07-04 | publisher = Ynetnews}}</ref><ref>{{cite news | url=http://fr.jpost.com/servlet/Satellite?cid=1188392502053&pagename=JPost/JPArticle/ShowFull | title= New training aims to help tanks cope in hostile territory | first = Yaakov | last = Katz | publisher = [[The Jerusalem Post]] | date=August 31, 2007}}</ref>

The Merkava IV was used more extensively during the [[Gaza War]], as it had been received by the IDF in increasing numbers since 2006, replacing more of the Merkava II and III versions of the tank that were in service. One brigade of Merkava IVs managed to bisect the Gaza strip in five hours without casualties. The commander of the brigade stated that battlefield tactics had been greatly revised since 2006. Tactics had also been modified to focus on [[asymmetric war|asymmetric]] or guerilla war threats, in addition to the conventional war scenarios that the Merkava had primarily been designed to combat.<ref>{{citation | publisher = The Jerusalem Post | date = Aug 13, 2009 21h20 | title = Security and Defense: 'The tank is one of the most technologically advanced platforms around’ | first = Yaakov | last = Katz}}.</ref> By October 2010, the IDF had begun to equip the first Merkava IVs with the Trophy active protection system, to improve the tanks' protection against advanced anti-tank missiles which use [[tandem-charge]] [[HEAT]] warheads.<ref>{{citation | url = http://www.jpost.com/Israel/Article.aspx?id=191194 | title = IDF launches massive Ground Forces exercise | publisher = Jerusalem Post | first = Yaakov | last = Lappin | date = 2010-10-13}}</ref><ref name=weiss>{{Cite news|last=Weiss|first=Efrat|title=IDF successfully tests new tank defense system|work=Ynetnews|accessdate=2009-08-07|date=2009-08-07|url=http://www.ynetnews.com/articles/0,7340,L-3758478,00.html}}</ref> Added protection systems included an Elbit laser-warning system and IMI in-built smoke-screen grenades.<ref name= "Merkava Mk IV breaks cover"/>

In December 2010, Hamas in Gaza fired an [[AT-14 Kornet]] anti-tank missile at a Merkava Mark III tank stationed on the Israel-Gaza border near [[Bureij|Al-Bureij]]. It had hitherto not been suspected that Hamas possessed such a sophisticated missile. The missile penetrated the tank's armour, but in this instance it caused no injuries among its crew . As a result of the attack, Israel decided to deploy, along the Gaza border, its first Merkava Mark IV battalion equipped with the [[Trophy active protection system]].<ref>{{citation | url = http://www.jpost.com/Defense/Article.aspx?id=200423 | title = IDF predicts violence to subside despite Gaza pounding | publisher = The Jerusalem Post | first1 = Yaakov | last1 = Katz | first2 = Rebecca Anna | last2 = Stoil | date = 12/21/2010 15:43}}.</ref>

In May 2012, Israel offered procurement of Merkava IV tanks to the [[Colombian Army]]. The sale would include 25-40 tanks at an approximate cost of $6 million each, as well as a number of [[Namer]] APCs.

Following the [[Second Intifada]] the Israel Defense Forces modified some of their Merkava's to satisfy the needs of [[urban warfare]].
 +
 
 +
===Merkava LIC===
 +
These are Merkava Mark III BAZ or Mark IV tanks, converted for urban warfare. The '''LIC''' designation stands for "[[Low intensity conflict]]", underlining its emphasis on counter-insurgency, street-to-street inner-city asymmetrical type warfare of the 21st century.<ref name="defense1">{{cite web | url = http://www.defense-update.com/products/m/merkava-lic.htm |title= LIC Modeled Merkava Mk-3 Baz |accessdate=2008-07-04 |publisher=Defense Update}}</ref>
 +
 
 +
The Merkava is equipped with a turret 12.7&nbsp;mm caliber coaxial machine gun, which enables the crew to lay down fairly heavy cover fire without using the main gun (which is relatively ineffective against individual enemy combatants). Like the new remote-operated weapon station, the coaxial machine-gun is fired from inside the tank without exposing the crew to small-arms fire and snipers.
 +
 
 +
The most sensitive areas of a tank, its optics, exhaust ports and ventilators, are all protected by a newly developed high-strength metal mesh, to prevent the possibility of explosives charges being planted there.<ref name="defense1" />
 +
 
 +
Rubber whip pole-markers with LED tips and a driver's rear-facing camera have been installed to improve navigation and maneuverability in an urban environment by day or by night.
 +
 
 +
===Merkava ''Tankbulance''===
 +
Some Merkava tanks have been fitted with full medical and [[ambulance]] capabilities while retaining their armament (but carrying less ammunition than the standard tank). The cabin area has been converted for carrying injured personnel and has had two [[stretcher]]s and [[life support]] medical station systems added with a full medical team complement to operate under combat conditions with a Merkava battalion. The vehicle has a rear door to facilitate evacuation under fire, and can provide covering fire.
 +
 
 +
The "tankbulance" is not an unarmed ambulance and as such is not protected by the [[Geneva Convention]]s provisions regarding ambulances, but it is far less vulnerable to accidental or deliberate fire than an ambulance or [[armored personnel carrier]].
 +
 
 +
===Merkava IFV ''Namer''===
 +
[[File:IDF-Namer003.jpg|thumb|upright|Namer in [[Yad La-Shiryon]] 62nd [[Independence Day (Israel)|Independence Day]] exhibition.]]

 +
Namer (Hebrew: [[leopard]], which is also an abbreviation of "'''Na'''gmash (APC) '''Mer'''kava"), is an [[infantry fighting vehicle]] based on the Merkava Mark IV chassis. In service since 2008, the vehicle was initially called ''Nemmera'' (Hebrew: leopardess), but later renamed to ''Namer''.

On 14 July 2011, [[The Jerusalem Post]] reported that the IDF had begun developing a successor for the Merkava series of tanks. The development was started in part by the arrival of the [[Trophy (countermeasure)|Trophy]] [[active protection system]]. With the system's ability to intercept threats at a stand-off distance, there was a review of the need for vehicles like the Merkava to have thick, heavy layers of armor.<ref>{{Citation | url = http://www.jpost.com/Defense/Article.aspx?id=229295 | title = IDF considering replacements for heavy Merkava tank | newspaper = The Jerusalem Post | date = July 14, 2011}}.</ref> The Merkava Tank Planning Directorate set up a team to study principles for a future tank and present ideas for an armored fighting vehicle to provide mobile firepower on a future battlefield. The team reviewed basic design principles including lessening its weight, armor thickness compared to an APS to intercept anti-tank threats, reducing the crew size, and the type of main gun. Horsepower capabilities and heavy and light track systems compared to a wheeled chassis were also considered. With future battlefield condition developments affecting design features, the vehicle may not be considered a "tank" in the traditional sense.<ref>[http://www.israeldefense.com/?CategoryID=411&ArticleID=549 After the Merkava: The Next Generation Tank] - Israeldefense.com, 14 August 2011</ref> By July 2012, details began to emerge of considerations for developing technologies for the new design. One possibility is the replacement of the traditional main gun with a [[Directed-energy weapon|laser cannon]] or an [[electromagnetic pulse]] cannon. Other improvements could include a [[Hybrid vehicle|hybrid-electric engine]] and a reduced crew of two. The goals of the new tank are to make it faster, better protected, more interoperable and lethal than the current Merkava.<ref>{{Citation | url = http://www.jpost.com/Defense/Article.aspx?id=277178 | title = The IDF’s future tank: Electromagnetic cannon | newspaper = The Jerusalem Post | date = July 12, 2012}}.</ref>
  
==Notes==
+
The 65-ton Merkava is not regarded as useful for missions other than conventional warfare. The Israeli Army Armored Corps wants a lighter and highly mobile vehicle for rapid-response and urban warfare situations that can fill multiple roles. In 2012, the [[Ministry of Defense (Israel)|Defense Ministry]] drafted a program for development of a new family of light armored vehicles called '''Rakiya''' (Horizon), a Hebrew acronym for '''Future Manned Combat Vehicle (FMCV)'''. The FMCV is planned to weight 35 tons and have sufficient armor and weapons for both urban and conventional military operations. Instead of one multi-mission chassis, separate vehicles in distinct variants will perform different roles with all vehicles using common components. Vehicles are likely to be wheeled to maneuver in urban environments and move troops and equipment around in built-up areas. While the FMCV will be a fifth-generation vehicle as a follow-on to the Merkava IV, it will not be a replacement for the tank. The Merkava and Namer heavy tracked vehicles will remain in service for decades, while FMCV vehicles are to address entirely different operational requirements. Although the program seems similar to the American [[Future Combat Systems]] effort, which failed to produce a family of rapidly deployable lightweight ground vehicles, program officials say they learned from the American experience and that the FMCV was more focused and driven by simpler and more reasonable requirements based on cost considerations. Officials expect requirements for a range of configurations for FMCV light armored vehicles to be approved in 2014 and solicited to Israeli and American companies. The IDF hopes for the FMCV family of vehicles be operational by 2020.<ref>[http://www.defensenews.com/article/20121216/DEFREG04/312160001/Israel-Develop-Family-New-Armored-Vehicles Israel To Develop Family Of New Armored Vehicles] - Defensenews.com, 16 December 2012</ref><ref>[http://www.worldtribune.com/2013/01/16/israel-lightens-up-will-replace-heavy-tanks-with-versatile-light-armored-vehicles/ Israel lightens up: Will replace heavy tanks with versatile light armored vehicles] - Worldtribune.com, 16 January 2013</ref>

Revision as of 04:20, 12 May 2014

Template:Infobox weapon Template:Cold War tanks Template:Post-Cold War tanks The Merkava (Hebrew: Template:Audio, "chariot") is a main battle tank used by the Israel Defense Forces. The tank began development in 1973 and entered official service in 1979. Four main versions of the tank have been deployed. It was first used extensively in the 1982 Lebanon War. The name "Merkava" was derived from the IDF's initial development program name.

It is designed for rapid repair of battle damage, survivability, cost-effectiveness and off-road performance. Following the model of contemporary self-propelled howitzers, the turret assembly is located closer to the rear than in most main battle tanks. With the engine in front, this layout is intended to grant additional protection against a frontal attack, especially for the personnel in the main hull, like the driver. It also creates more space in the rear of the tank that allows increased storage capacity, as well as a rear entrance to the main crew compartment allowing easy access under enemy fire. This allows the tank to be used as a platform for medical disembarkation, a forward command and control station, and an armoured personnel carrier. The rear entrance's clamshell-style doors provide overhead protection when off- and on-loading cargo and personnel.

It was reportedly decided shortly before the beginning of the 2006 Lebanon War that the Merkava line would be discontinued within four years.[1] However, on 7 November 2006, Haaretz reported that an Israeli General Staff assessment had ruled of the Merkava Mark IV that "if properly deployed, the tank can provide its crew with better protection than in the past," and deferred the decision on discontinuing the line.[2] On 16 August 2013, Israeli Defense Minister Moshe Ya'alon announced the decision to resume production of the Merkava main battle tank for the IDF Armored Corps.[3][4]

Development

In 1965, Israel's military establishment began research and development on a domestically-produced tank, the "Sabra" [5] (not to be confused with the later model of the same name now in service). Initially, Britain and Israel collaborated to adapt the United Kingdom's Chieftain tank that had entered British Army service in 1966.[6] However, in 1969, Britain decided not to sell the tank to Israel for political reasons.[7]

Israel Tal, who was serving as a brigade commander after the Suez Crisis, restarted plans to produce an Israeli-made tank, drawing on lessons from the 1973 Yom Kippur War, in which Israeli forces were outnumbered by those of the Middle East's Arab nations.[7]

By 1974, initial designs were completed and prototypes were built. After a brief set of trials, work began to retool the Tel HaShomer ordnance depot for full-time development and construction. After the new facilities were completed, the Merkava was announced to the public in the International Defense Review periodical. The first official images of the tank were then released to the American periodical Armed Forces Journal on 4 May 1977. The IDF officially adopted the tank in December 1978. The first Merkava Mk. 1 tanks were supplied to the IDF in April 1979, nearly nine years after the decision to produce the Merkava Mk. 1 tank was taken.

Primary contractors

The lead organization for system integration of the Merkava's main components is Israel Military Industries (IMI). The Israeli Ordnance Corps are responsible for final Merkava assembly. Contributors to the vehicle include:

General characteristics

Firepower

The Merkava Mark I and II were armed with a 105 mm M68 gun. The Mark III, Mark III Dor Dalet BAZ kassag, and the Mark IV are armed with an IMI 120 mm smoothbore gun.

Each model of the Merkava has two 7.62 machine guns for anti-infantry defense and a 60 mm mortar.

Mobility

The tank's 1,500 horsepower turbocharged diesel engine was designed by MTU and is manufactured under license by L-3 Communication Combat Propulsion Systems (formerly General Dynamics). The Mark IV's top road speed is 64 km/h.[citation needed]

Variants

Merkava Mark I

Merkava Mark I at Yad La-Shiryon.

The Mark I, operational since 1979, is the original design created as a result of Israel Tal's decision, and was fabricated and designed for mass production. The Mark I weighed 63 tonnes and had a 900 horsepower (670 kW) diesel engine, with a power-to-weight ratio of 14 hp/ton. It was armed with the 105 millimeter M68 main gun (a licensed copy of the British Royal Ordnance L7), two 7.62 mm machine guns for anti-infantry defense,[9] and a 60 mm mortar mounted externally, with its operator not completely protected by the tank's hull.

The general design borrows the tracks from the British Centurion tank, which had seen extensive use during the Yom Kippur war.

The Merkava was first used in combat during the 1982 Lebanon War, where Israel deployed 180 units. Although they were a success, the M113 APCs that accompanied them were found to have several defects and were withdrawn. Merkavas were converted into makeshift APCs or armored ambulances by taking out the palleted ammunition racks in storage. Ten soldiers or walking wounded could enter and exit through the rear door.

After the war, many adjustments and additions were noted and designed, the most important being that the 60 mm mortar needed to be installed within the hull and engineered for remote firing—a valuable feature that the Israelis had initially encountered on their Centurion Mk3s with their 2" Mk.III mortar.[10] A shot trap was found beneath the rear of the turret bustle, where a well-placed shot could jam the turret completely. The installation of chain netting to disperse and destroy rocket propelled grenades and anti-tank rockets before impacting the primary armor increased survivability.

Merkava Mark II

Template:Multiple image The Mark II was first introduced into general service in April 1983 and incorporated numerous small upgrades as a result of the previous year's incursion into Lebanon. The new tank was optimized for urban warfare and low intensity conflicts, with a weight and engine no greater than the Mark I.[11]

The Mark II used the same 105 mm main gun and 7.62 mm machine guns as the Mark I, but the 60 mm mortar was redesigned during construction to be located within the hull and configured for remote firing to remove the need to expose the operator to enemy small-arms fire. An Israeli-designed automatic transmission and increased fuel storage for increased range was installed on all further Mark IIs. Anti-rocket netting was fitted for increased survivability against infantry equipped with anti-tank rockets. Many minor improvements were made to the fire-control system. Updated meteorological sensors, crosswind analyzers, and thermographic optics and image intensifiers gave greater visibility and battlefield awareness.

Incrementally improved versions of the original Mark II were designated, with many of these tanks still in service today:

  • Mark IIB, with thermal optics and unspecified updates to the fire control system.
  • Mark IIC, with more armor on the top of the turret to improve protection against attack from the air.
  • Mark IID, with modular composite armor on the chassis and turret, allowing rapid replacement of damaged armor.

Merkava Mark III

File:Merkava III Showoff.ogv The Merkava Mark III was introduced in December 1989, and had upgrades to the drivetrain, powertrain, armament, and electronic systems. The most prominent addition was the incorporation of the locally developed IMI 120 mm gun.[12] This gun and a larger 1,200 horsepower (890 kW) diesel engine increased the total weight of the tank to 65 tonnes (143,000 lb), but the larger engine increased the maximum cruising speed to 60 km/h (37 mph).[13]

The turret was re-engineered for movement independent of the tank chassis, allowing it to track a target regardless of the tank's movement. Many other improvements were made, including:

  • External two-way telephone for secure communications between the tank crew and dismounted infantry,
  • Upgraded ammunition storage containers to minimize ammunition cook-off,
  • Addition of laser designators,
  • Incorporation of the Kasag modular armor system, designed for rapid replacement and repair in the battlefield and for quick upgrading as new designs and sophisticated materials become available,
  • Creation of the Mark IIIB, with unspecified armor upgrades.

BAZ System

The 1995 Mark III BAZ (Hebrew acronym for ברק זוהר, Barak Zoher, signifying Shining Lightning[14]) had many improved and additional systems including:

  • Upgraded fire-control system components, from Electro Optics Industries (EL-OP) and Elbit, provides the tank with the ability to engage moving targets while on the move (an automatic target tracker),
  • NBC protection systems,
  • Locally developed central air-conditioning system,
  • Added improvements in ballistic protection,
  • The Mark IIID has removable modular composite armor on the chassis and turret.

Dor-Dalet

The last generation of the Mark III class was the Mark IIID Dor-Dalet (Hebrew: Fourth Generation), which included several components as prototypes to be introduced in the Mark IV.

  • Upgraded and strengthened tracks (built by Caterpillar, designed in Israel),
  • Installation of the R-OWS.

Merkava Mark IV

Template:Multiple image The Mark IV is the most recent upgrade of the Merkava tank and has been in development since 1999. The upgrade's development was announced in an October 1999 edition of the Bamachaneh ("At the Camp") military publication. However, new Merkava Mark IIIs continued to be produced until 2003. The first Merkava IVs were in production in limited numbers by the end of 2004.[15]

The model has a new fire-control system, the El-Op Knight Mark 4. Removable modular armor, from the Merkava Mark IIID, is used on all sides, including the top and a V-shaped belly armor pack for the underside. This modular system is designed to allow for damaged tanks to be rapidly repaired and returned to the field.

Tank rounds are stored in individual fire-proof canisters, which reduce the chance of cookoffs in a fire inside the tank. The turret is "dry"; no active rounds are stored in it.

Some features, such as hull shaping, exterior non-reflective paints, and shielding for engine heat plumes mixing with air particles to confuse enemy thermal imagers, were carried over from the IAI Lavi program of the Israeli Air Force to make the tank harder to spot by heat sensors and radar.

The Mark IV includes the larger 120 mm main gun of the previous versions, but can fire a wider variety of ammunition, including HEAT and sabot rounds like the APFSDS kinetic energy penetrator, using an electrical semi-automatic revolving magazine for 10 rounds. It also includes a much larger 12.7 mm machine gun for anti-vehicle operations (most commonly used against technicals).[16]

The new fire-control system enables the Merkava to shoot down helicopters such as the Russian Mil Mi-24 and the French Gazelle, both of which are used by Israel's neighbors.[citation needed]

The Mark IV has the Israeli-designed "TSAWS (Tracks, Springs, and Wheels System)" caterpillar track system, called "Mazkom" (Template:Lang-he) by troops. This system is designed to endure the harsh basalt rock conditions of Lebanon and the Golan Heights with minimal "track-shedding".

The tank carries the Israeli Elbit Systems BMS (Battle Management System; Hebrew: צי"ד), a centralised system that takes data from tracked units and UAVs in theater, displays it on color screens, and distributes it in encrypted form to all other units equipped with BMS in a given theater.

The Merkava IV has been designed for rapid repair and fast replacement of damaged armour, with the implementation of sections of modular armour that can be easily removed and replaced. It is also designed to be cost-effective in production and maintenance, and as a result its unit cost is lower than for a number of other tanks used by Western armies.

Combat history

File:Merkavah Tank of Tzur Maor and his Crew.jpg
An Israeli Merkava 1 in Lebanon after being hit, 1982

The Merkava was used widely during the 1982 Lebanon War. The tank outperformed Syrian tanks (mostly T-62s) and proved largely immune to anti-tank weapons of the time (the AT-3 Sagger and RPG-7) that were used against it. It was judged to be a significant improvement over Israel's previously most effective main battle tank at that time, the Centurion tank.[18] 34 Merkava tanks were lost during war[19][page needed]

In February 2002, a Merkava III was destroyed by a roadside bomb near Netzarim settlement in the Gaza Strip. The tank was lured into intervening in an attack on a settler convoy. The tank went over a heavy mine, which detonated and totally destroyed the tank. Four soldiers were killed in the blast. This was the first heavy tank to be destroyed during the Second Intifada.[20] A second Israeli tank, Merkava II or probably a Merkava III, was destroyed a month later in the same area and a further three soldiers were killed. A third Merkava II or III tank was destroyed near the Kissufim Crossing, when one soldier was killed and two wounded.[21]

The AT-14 Kornet anti-tank laser-guided missile

During the 2006 Lebanon War, five Merkava tanks were destroyed.[22] Only the minority of the tanks used during the war were Merkava Mark IVs, as by 2006 they had still only entered service in limited numbers. Hezbollah fired over 1,000 anti-tank missiles during the conflict against both tanks and dismounted infantry.[22] Some 45 percent of all tanks and armoured vehicles hit with antitank missiles during the conflict suffered some form of armour penetration.[22] In total, 15 tank crewmen were killed by these ATGM penetrations.[23] The penetrations were caused by tandem warhead missiles. Hezbollah weaponry was believed to include advanced Russian RPG-29 'Vampir', AT-5 'Konkurs', AT-13 'Metis-M', and laser-guided AT-14 'Kornet'[24] HEAT missiles. The IDF reported finding the state-of-the-art Kornet ATGMs on Hezbollah positions in the village of Ghandouriyeh.[25] Several months after the cease-fire, reports have provided detailed photographic evidence that Kornet ATGMs were indeed both in possession of, and used by, Hezbollah in this area.[26][27] Another Merkava IV tank crewman was killed when a tank ran over an improvised explosive device (IED). This tank had additional V-shaped underside armor, limiting casualties to just one of the seven personnel (four crewmen and three infantrymen) on board. In total, five Merkava tanks (two Merkava IIs, one Merkava III, and two Merkava IVs) were destroyed.[22] Of these two Merkava Mark IVs, one was by powerful IEDs, and the other by Russian AT-14 'Kornet' missiles. The Israeli military said that it was satisfied with the Merkava Mark IV's performance, and attributed problems to insufficient training before the war.[28][29] In total, 50 Merkava tanks (predominantly Merkava IIs and IIIs) were damaged, eight of which remained serviceable on the battlefield. 21 tanks suffered armour penetrations (15 from missiles, and 6 from IEDs and anti-tank mines).[22]

After the 2006 war, and as the IDF becomes increasingly involved in unconventional and guerrilla warfare, some analysts say the Merkava is too vulnerable to advanced anti-tank missiles, that in their man-portable types can be fielded by guerrilla warfare opponents.[30][31] Other post-war analysts, including David Eshel, disagree, arguing that reports of losses to Merkavas were overstated and that "summing up the performance of Merkava tanks, especially the latest version Merkava Mark IV, most tank crews agree that, in spite of the losses sustained and some major flaws in tactical conduct, the tank proved its mettle in its first high-saturation combat."[32] On a comparison done by the armor corps newsletter, it was shown that the average number of crewmen killed per tank penetrated was reduced from 2 during the Yom Kippur War to 1.5 during the 1982 Lebanon War to 1 during the 2006 Lebanon War proving how, even in the face of the improvement in anti-tank weaponry, the Merkava Mark IV provides better protection to its crew (although only a limited number of the Israeli tanks used in 2006 were Merkava Mark IVs). The IDF wanted to increase orders of new Merkava Mark IV tanks, and planned to add the Trophy active protection system to Merkava Mark IV tanks, and to increase joint training between crews and Israeli antitank soldiers.[33][34]

The Merkava IV was used more extensively during the Gaza War, as it had been received by the IDF in increasing numbers since 2006, replacing more of the Merkava II and III versions of the tank that were in service. One brigade of Merkava IVs managed to bisect the Gaza strip in five hours without casualties. The commander of the brigade stated that battlefield tactics had been greatly revised since 2006. Tactics had also been modified to focus on asymmetric or guerilla war threats, in addition to the conventional war scenarios that the Merkava had primarily been designed to combat.[35] By October 2010, the IDF had begun to equip the first Merkava IVs with the Trophy active protection system, to improve the tanks' protection against advanced anti-tank missiles which use tandem-charge HEAT warheads.[36][37] Added protection systems included an Elbit laser-warning system and IMI in-built smoke-screen grenades.[15]

In December 2010, Hamas in Gaza fired an AT-14 Kornet anti-tank missile at a Merkava Mark III tank stationed on the Israel-Gaza border near Al-Bureij. It had hitherto not been suspected that Hamas possessed such a sophisticated missile. The missile penetrated the tank's armour, but in this instance it caused no injuries among its crew . As a result of the attack, Israel decided to deploy, along the Gaza border, its first Merkava Mark IV battalion equipped with the Trophy active protection system.[38]

On 1 March 2011, a Merkava MK IV stationed near the Gaza border, equipped with the Trophy active protection system, successfully foiled a missile attack aimed towards it and became the first operational success of the system.[39]

Export

In May 2012, Israel offered procurement of Merkava IV tanks to the Colombian Army. The sale would include 25-40 tanks at an approximate cost of $6 million each, as well as a number of Namer APCs. With the threat of the expanding Venezuelan military, it would strengthen Colombian armored forces against Venezuelan T-72 tanks.[40][41]

Derivatives

Following the Second Intifada the Israel Defense Forces modified some of their Merkava's to satisfy the needs of urban warfare.

Merkava LIC

These are Merkava Mark III BAZ or Mark IV tanks, converted for urban warfare. The LIC designation stands for "Low intensity conflict", underlining its emphasis on counter-insurgency, street-to-street inner-city asymmetrical type warfare of the 21st century.[42]

The Merkava is equipped with a turret 12.7 mm caliber coaxial machine gun, which enables the crew to lay down fairly heavy cover fire without using the main gun (which is relatively ineffective against individual enemy combatants). Like the new remote-operated weapon station, the coaxial machine-gun is fired from inside the tank without exposing the crew to small-arms fire and snipers.

The most sensitive areas of a tank, its optics, exhaust ports and ventilators, are all protected by a newly developed high-strength metal mesh, to prevent the possibility of explosives charges being planted there.[42]

Rubber whip pole-markers with LED tips and a driver's rear-facing camera have been installed to improve navigation and maneuverability in an urban environment by day or by night.

Merkava Tankbulance

Some Merkava tanks have been fitted with full medical and ambulance capabilities while retaining their armament (but carrying less ammunition than the standard tank). The cabin area has been converted for carrying injured personnel and has had two stretchers and life support medical station systems added with a full medical team complement to operate under combat conditions with a Merkava battalion. The vehicle has a rear door to facilitate evacuation under fire, and can provide covering fire.

The "tankbulance" is not an unarmed ambulance and as such is not protected by the Geneva Conventions provisions regarding ambulances, but it is far less vulnerable to accidental or deliberate fire than an ambulance or armored personnel carrier.

Merkava IFV Namer

Namer in Yad La-Shiryon 62nd Independence Day exhibition.

Namer (Hebrew: leopard, which is also an abbreviation of "Nagmash (APC) Merkava"), is an infantry fighting vehicle based on the Merkava Mark IV chassis. In service since 2008, the vehicle was initially called Nemmera (Hebrew: leopardess), but later renamed to Namer.

Namer is equipped with a Samson Remote Controlled Weapon Station (RCWS) armed with either a .50 M2 Browning Heavy Machinegun or a Mk 19 Automatic Grenade Launcher. It also has a 7.62 mm MAG machine gun, 60 mm mortar and smoke grenades. Like Merkava Mark IV, it is optimized for high level of crew survival on the battlefield. The Namer has a three-man crew (commander, driver, and RCWS gunner) and may carry up to nine infantrymen and a stretcher. An ambulance variant can carry two casualties on stretchers and medical equipment.

The Golani Brigade used two Namer IFVs during Cast Lead operation.

Merkava ARV Nemmera

The Merkava Armored Recovery Vehicle initially called Namer (Hebrew: leopard), but subsequently renamed to Nemmera (Hebrew: leopardess). It is an armored recovery vehicle based on a Merkava Mark III or IV chassis. It can tow disabled tanks and carries a complete Merkava back-up power pack that can be changed in the field in under 90 minutes.

There are two versions of Nemmera: the heavier equipped with a 42 ton-meter crane and a 35 ton-meter winch, and the smaller equipped with a smaller crane.

Merkava Howitzer Sholef

Sholef in Beit ha-Totchan, Zikhron Ya'akov, Israel.

Two prototypes of Sholef ("Gunslinger" or "Slammer") 155 mm self-propelled howitzer with automatic loading system were built by Soltam in 1984–1986. The 45-ton vehicle had a long 155 mm gun barrel giving a range of 45+ km. Using GPS, inertial navigation, and an internal fire control computer, it was also capable of direct fire while on the move. It never entered production.[43]

FMCV

On 14 July 2011, The Jerusalem Post reported that the IDF had begun developing a successor for the Merkava series of tanks. The development was started in part by the arrival of the Trophy active protection system. With the system's ability to intercept threats at a stand-off distance, there was a review of the need for vehicles like the Merkava to have thick, heavy layers of armor.[44] The Merkava Tank Planning Directorate set up a team to study principles for a future tank and present ideas for an armored fighting vehicle to provide mobile firepower on a future battlefield. The team reviewed basic design principles including lessening its weight, armor thickness compared to an APS to intercept anti-tank threats, reducing the crew size, and the type of main gun. Horsepower capabilities and heavy and light track systems compared to a wheeled chassis were also considered. With future battlefield condition developments affecting design features, the vehicle may not be considered a "tank" in the traditional sense.[45] By July 2012, details began to emerge of considerations for developing technologies for the new design. One possibility is the replacement of the traditional main gun with a laser cannon or an electromagnetic pulse cannon. Other improvements could include a hybrid-electric engine and a reduced crew of two. The goals of the new tank are to make it faster, better protected, more interoperable and lethal than the current Merkava.[46]

The 65-ton Merkava is not regarded as useful for missions other than conventional warfare. The Israeli Army Armored Corps wants a lighter and highly mobile vehicle for rapid-response and urban warfare situations that can fill multiple roles. In 2012, the Defense Ministry drafted a program for development of a new family of light armored vehicles called Rakiya (Horizon), a Hebrew acronym for Future Manned Combat Vehicle (FMCV). The FMCV is planned to weight 35 tons and have sufficient armor and weapons for both urban and conventional military operations. Instead of one multi-mission chassis, separate vehicles in distinct variants will perform different roles with all vehicles using common components. Vehicles are likely to be wheeled to maneuver in urban environments and move troops and equipment around in built-up areas. While the FMCV will be a fifth-generation vehicle as a follow-on to the Merkava IV, it will not be a replacement for the tank. The Merkava and Namer heavy tracked vehicles will remain in service for decades, while FMCV vehicles are to address entirely different operational requirements. Although the program seems similar to the American Future Combat Systems effort, which failed to produce a family of rapidly deployable lightweight ground vehicles, program officials say they learned from the American experience and that the FMCV was more focused and driven by simpler and more reasonable requirements based on cost considerations. Officials expect requirements for a range of configurations for FMCV light armored vehicles to be approved in 2014 and solicited to Israeli and American companies. The IDF hopes for the FMCV family of vehicles be operational by 2020.[47][48]
