==Description==
The '''''Zeus''''' was first built by the [[Lyran Commonwealth]] in [[Introduction Year::2787]], just as the [[First Succession War]] began.  Built at the request of [[Lyran Commonwealth Armed Forces]] commanders for a new light-assault '[[Mech]] designed to engage the enemy at long range and perform hit-and-run attacks, the ''Zeus'' is fast enough to keep up with most heavy 'Mechs, and with a sturdy frame, eleven and a half tons of [[standard armor]] and a versatile weapons array, is equally capable of defeating them.  Its use of reliable, low-maintenance and easily modified systems at a time when most 'Mechs were built with cutting-edge technology also proved fortuitous, allowing the ''Zeus'' to be produced long after those advanced components had become [[Lostech]].<ref name=TRO3025r>''Technical Readout: 3025 Revised</ref><ref name=TRO3039/>

On the drawing board three years prior to its introduction, the first two prototypes of the ''Zeus'' would receive their first "test run" when they were forced to fight off an assault on the [[Hesperus II]] factory by the [[Draconis Combine Mustered Soldiery]].  As the enemy broke through Lyran lines, the two 'Mechs were called up to assist, and through sheer novelty and long-range firepower, forced the [[Kurita]]ns to pause. This allowed additional reinforcements to push DCMS forces back. While successful in holding off the attack, these prototypes were noticeably more advanced than the production model and armed with a [[PPC]], which proved erratic and unreliable during the battle.  The cause of this behavior was later discovered to be insufficient shielding which created wild magnetic interactions between the weapon and the ''Zeus''<nowiki>'</nowiki>s engine.  To ensure the ''Zeus'' was delivered to the front-lines quickly it was decided to replace the advanced energy weapon with the simpler [[autocannon]].<ref name=TRO3025r/><ref name=TRO3039/>

The 'Mech would first appear in significant numbers when the [[15th Lyran Guards]] recaptured the planet [[Sakhalin (LC)|Sakhalin]], and through the course of the [[Succession Wars (History)|Succession Wars]] the ''Zeus'' had a long and storied history within the Commonwealth, becoming a well-respected assault 'Mech.  After the end of the [[Third Succession War]] advances had allowed engineers to mount a PPC on the ''Zeus'' again, with the resulting ZEU-6T model becoming the standard during the [[Fourth Succession War]] and later the [[War of 3039]].  The design also won high praise among [[mercenary]] units, none more so than [[Zeta Battalion]] of [[Wolf's Dragoons]].<ref name=TRO3025r/><ref name=TRO3039/>

The ''Zeus'' would face resistance by some units of the former [[AFFS]] following the creation of the [[Federated Commonwealth]], whose "Davion pride" prevented them from making use of the 'Mech despite its superiority to many of their own machines.  Likewise as the FedCom military increasingly took on a Davion flavor many Lyran commanders were insistent that their pride and joy was too valuable to give up, and so prodded Defiance Industries to produce new models which made use of newly recovered [[Star League]] Lostech.  The debut of the ZEU-9S ''Zeus'' would see production of the previous variants discontinued and examples of this signature Lyran 'Mech shipped to all corners of the Commonwealth as a symbol of the new alliance.  By the time of the [[FedCom Civil War]] though, the majority of ''Zeus'' 'Mechs were in Lyran hands, with many of those given to Davion units having been relegated to rear-guard duty or sold to mercenaries.  New variants would continue to be produced for the [[LAAF]] and, following their capture of Hesperus II in [[3070]], the [[Word of Blake Militia]].<ref name=TRO3050U/><ref>''Technical Readout: 3050'', p. 164</ref>

==Weapons and Equipment==
The prototype ''Zeus'' carried a PPC, but the most common, best-known variant of the ''Zeus'', the ZEU-6S, mounted as its primary weapon a [[Defiance Type J]] [[Autocannon/5]] mounted in the left arm, backed up by a [[Coventry Star Fire]] [[LRM-15]] in the right arm for engaging enemies at long ranges.  The missile launcher's placement, set around and back from a central core, was a unique way to protect the weapon while allowing the ''Zeus'' to use that arm as a bludgeon in hand-to-hand combat; the complicated arrangement also made the launcher prone to failure without regular maintenance.  Both were fed by a ton of ammunition each, a source of concern among some pilots who preferred more shots from the LRM-15, though others noted by the point it ran dry the armor was probably compromised and an empty missile bin was less likely to explode.  The [[Thunderbolt A5M]] [[Large Laser]], mounted in the left torso and used to engage enemies at intermediate ranges, was also a unique challenge for Defiance.  Whereas a typical barrel-type large laser wouldn't fit in the compact space, the company used their rare knowledge of fiber optics to design a smaller though no less effective weapon.  Finally two [[Defiance B3M]] medium lasers, one mounted in the center torso and one in the left facing rearwards, were used for close-in work. This combination of weaponry made the ''Zeus'' a 'Mech that was deadly at any range.<ref name=IRS>''Classic BattleTech Introductory Record Sheets'', p. 22</ref><ref name=TRO3025r/><ref name=TRO3039/>

==Variants==
*; ZEU-5S : One of the two original models of the ''Zeus'', it was equipped with an [[Ultra AC/5]] with two tons of ammunition, the LRM-15 was linked to an [[Artemis IV FCS]], and the large laser was an [[ER Large Laser|extended range model]].  Fourteen [[double heat sink]]s kept the entire machine cool.<ref name=TRSWp156f /> BV (2.0) = 1,499<ref>''Record Sheets 3039 Unabridged'', p. 249</ref>

*; ZEU-5T : One of the two original models of the ''Zeus'', it was similar to the 5S with an LRM-15/Artemis IV combination and an extended range large laser, but was equipped with an [[ER PPC]]. The use of [[ferro-fibrous armor]] increased the 'Mech's protection and seventeen double heat sinks kept the entire machine cool.<ref name=TRSWp156f /> BV (2.0) = 1,729<ref>''Record Sheets 3039 Unabridged'', p. 250</ref>

*; ZEU-6A : Introduced in [[2940]], and an apparent precursor to the 6T, the 6A trades the LRM-15 and two heat sinks for three [[SRM-6]]'s with one ton of ammunition in the right arm. BV (2.0) = 1,405<ref>''Record Sheets: Succession Wars'', p. 237</ref><ref>[http://www.masterunitlist.info/Unit/Details/7432/zeus-zeu-6a MUL online entry for the ZEU-6A variant]</ref>

*; ZEU-6T : Advancements after the Third Succession War led to the 6T model which carried as its primary weapon a [[Parti-Kill Heavy Cannon|Parti-Kill]] [[PPC]]. This weapon had the same effective range as the AC/5 and did twice as much damage, but also created a great deal of excess heat (partially mitigated by two additional heat sinks). The 6T was otherwise identical to the 6S and would go on to become the standard model, as well as serving as a base for the later 9S and 9T models.<ref name=TRSWp156f /> BV (1.0) = 1,170; BV (2.0) = 1,436<ref name=TRO3039/>

*; ZEU-6Y : Prototyped in [[2922]] as an experiment in logistical support, the 6Y kept the AC/5 in the right arm, but replaced the LRM-15 with a single [[LRM-10]] launcher and a single [[Binary Laser Cannon]] was installed in place of the large laser.  The missile downgrade was an attempt to alleviate the one problem in the ''Zeus''' otherwise headache-free design, and indeed field refits had shown that the ten-tube launchers were easily adaptable.  The addition of the little-loved binary cannon was a combination of two factors: fears that the slow-to-produce Thunderbolt laser was becoming [[Lostech]] and an attempt to give the ''Zeus'' a long-ranged and powerful energy weapon minus the side effects caused by its original PPC weapon.  Unfortunately the heat produced from this weapon caused catastrophic failures in the surrounding [[myomer]] bundles.  Engineers attempted to redesign the left torso to better dissipate heat, and eventually resorted to placing the cannon on an over-shoulder mount in the right torso, but in the end they couldn't solve the problem.  Defiance went on to produce this variant in limited numbers before abandoning the project. BV (2.0) = 1,323<ref name=XTRO:SWp8>''Experimental Technical Readout: Succession Wars, Volume 1'', p. 8</ref>

*; ZEU-9S : The 9S was an upgrade using Star League technology, debuting in [[3048]].  It replaced the standard heat sinks with double-strength models, the eleven tons of standard armor for the same weight in Glasgow Limited Primo Ferro-Fibrous plating, and added [[CASE]] to prevent ammunition explosions. It carried as its main weapon a [[Defiance 1001]] ER PPC in its left arm, retained as backup for long-range combat the Coventry Star Fire LRM-15 launcher and replaced the Thunderbolt large laser for a [[Cyclops XII]] [[ER Large Laser]]. For close combat, the 9S replaced the two medium lasers for [[Defiance P3M]] [[Medium Pulse Laser]]s.<ref name=TRO3050U/> BV (1.0) = 1,419; BV (2.0) = 1,639<ref name=MUL171>''Master Unit List: Battle Values'', p. 174</ref>

*; ZEU-9S2 : The 9S2 was a modified version of the 9S.  The armor and twelve double heat sinks of original were retained, but the engine was changed to an [[XL engine|extralight]].  A [[Gauss rifle]] took the place of the ER PPC while the right arm carried a pair of LRM-15s.  Though the Cyclops XII extended range laser was kept, the medium pulse lasers had to be removed to provide enough space for the modifications.  BV (2.0) = 1,769<ref>''Record Sheets: 3050 Unabridged (Inner Sphere)'', p. 233</ref>

*; ZEU-9S-DC : Introduced in 3049, this 9S subvariant trades the rear-mounted medium pulse laser and one double heat sink for a [[Command Console]]. BV (2.0) = 1,612<ref>''Record Sheets: 3050 Upgrades Unabridged (Inner Sphere)'', p. 232</ref><ref>[http://www.masterunitlist.info/Unit/Details/5438/zeus-zeu-9s-dc MUL online entry for the ZEU-9S-DC variant]</ref>

*; ZEU-9T : The 9T variant of the ''Zeus'' was introduced in [[3062]] just prior to the civil war and carried the 6T to its next logical step. The 'Mech was built with a [[Light Fusion Engine]] and carried thirteen and a half tons of ferro-fibrous armor. As its primary weapon, the 9T carried an ER PPC, backed by an LRM-15 launcher with an Artemis IV fire control system for greater missile accuracy and twice as much ammunition capacity. Also, for long-range combat, the 9T carried an ER Large Laser, while for close combat the 'Mech was armed with two medium pulse lasers and an [[ER medium laser]].  Deployment of the 9T was limited, first by fighting for control of Hesperus II during the civil war, then by the outbreak of the [[Jihad]].<ref name=TRO3050U/>  BV (1.0) = 1,480; BV (2.0) = 1,835<ref name=MUL171/>

*; ZEU-10WB : This variant was produced by the [[Word of Blake]] following their seizure of Hesperus II during the Jihad.  Rolling off assembly lines six months after the planet's capture, it was armed with a pair of [[Heavy PPC]]s, supplemented by an ER large laser, four ER medium lasers and fourteen tons of ferro-fibrous armor.  These new additions were made possible by the inclusion of an [[XL Gyro]] and [[Light Fusion Engine]], while seventeen double heat sinks were included for heat management.<ref name=TRO3050U/> BV (2.0) = 2,075<ref>''Record Sheets: 3050 Upgrade, Inner Sphere'', p. 136</ref>

*; ZEU-11S : Combining the best features of the ZEU-9T and ''Zeus X'' program, ZEU-11S blurs the Inner Sphere/[[Clan]]-tech divide thanks to Defiance's introduction of Clan-grade production lines. Built upon the 9T's frame, the 11S uses a Clan [[XL engine]] instead of a light model to free up more weight at no increase in bulk. Offensively a left-arm mounted Inner Sphere Gauss Rifle is supported by an Artemis IV enhanced Clan LRM-15 in the right arm and a Clan ER Large in the left torso, alongside two Clan ER mediums, one forward facing in the center torso with a rear-facing one in the right torso. Carrying three tons each of Gauss and LRM reloads, even with the inclusion of a [[Beagle Active Probe]], the 11S mounts [[CASE II]] in the left arm and right torso to shield against gauss or ammo detonations, along with an increased volume of IS standard ferro-fibrous armor protection.<ref name=RGIV2p13>''Recognition Guide: ilClan, vol. 3'', p. 13: "Zeus"</ref> BV (2.0) = 2,280<ref name=RGIV2p30>''Recognition Guide: ilClan, vol. 2'', p. 30: "Zeus ZEU-11S"</ref>

*[[Dual Cockpit]] refits: The [[Lyran Commonwealth]] (and later the [[Lyran Alliance]]) fitted some ''Zeus'' 'Mechs with [[Dual Cockpit]]s. The dual-cockpit versions were usually either a ZEUS-6S (with one medium laser removed to make room) or a ZEU-9S (with one less heat sink).

===Custom Variants===
*; ''Zeus Leonidas'' : The personal 'Mech of [[Hauptmann-General]] [[Leonidas Brannock]], commander of the [[4th Skye Guards]] during their assault on [[Glengarry]], the ''Zeus'' Leonidas was based on the ZEU-9S. It carried an [[Artemis IV]] enhanced [[LRM-20]] and a [[Gauss rifle]] (each with two tons of ammunition) in place of the PPC and LRM-15. The rest of the weapons remained the same. It also carried an extra heat sink, bringing the total to twelve. To make room for this equipment the ''Leonidas'' used an XL engine. BV (2.0) = 1,878<ref>''Historical Turning Points: Glengarry'', p. 15</ref>

===Apocryphal Variants===
{{ApocryphalContentStart}}
''From [[MechWarrior Online]]:''
*; ZEU-SK ''Skokomish'' : While there are no indications the MechWarrior known as [[Sealth (Character)|Sealth]] piloted anything other than a standard variant, in ''MechWarrior Online'' the ''Skokomish'' [[Hero 'Mech]] features extensive changes in both weapon loadout. Built around an XL engine and [[Endo Steel]] chassis, MWO's ''Skokomish'' retains only the left-arm AC/5 and center torso medium laser of the ZEU-6S, instead carrying paired SRM-6's in the right-arm supported at range by a left-torso mounted PPC and twin LRM-10s. Thirteen double heat sinks and two tons of reloads each for the [[autocannon]], [[short-range missile|short range]] and [[long range missile]] launchers make it a deadly combatant. Sealth's famed agility is replicated via technological means - MWO's ''Skokomish'' being fitted with a [[MASC]] system.<ref name=MWO>''MechWarrior Online'' "Resistance Heroes Sale Page"</ref>
