Editing Monitor (naval concept)

{{otheruses|the spacecraft design concept|other uses|Monitor}}
==Overview==
In the context of [[BattleTech]] spacecraft, the term '''Monitor''', although not clearly defined, is usually used to describe the concept of a [[WarShip]] without a [[jump drive]] core.

This drive core has no tactical value in combat but typically makes up 47.5% of a given WarShip's mass. The idea behind the Monitor concept is to free up almost twice as much mass for weapons, armor, and other combat-relevant systems by forgoing the jump drive. Monitors are theoretically vastly more powerful on a ton-per-ton basis compared to regular WarShips of the same mass.

==No Official Rules==
No official rules exist for Monitors. The very concept breaks the aerospace construction rules, as WarShips (with their size limit of 2,500,000 tons) mount a jump drive by definition. Under Canon rules, non–jump capable vessels must be built either as [[DropShip]]s (size limit of 100,000 tons) or even [[small craft]] (size limit of 200 tons). [[Space station]]s are immobile structures and cannot mount tactical maneuvering thrusters, giving them limited tactical value.

[[Gerald Hall]] pioneered the Monitor concept in the [[MechForce]] magazine [[MechQuarterly]] (vol. 4, issue 2), an official but [[canon|noncanon]] BattleTech publication. His suggested construction rules for Monitors were incorporated into the official BattleTech design program, [[HeavyMetal Aero]], but are not canonical and violate legal construction rules.

To put the issue to rest, he solicited an entry for Monitors in ''[[Experimental Technical Readout: Boondoggles]]'' to showcase that, and why, the concept was not viable in the BattleTech universe. However, within days of publication fans pointed out on the [[BattleTech Forum]] that the entry as written, which described a small number of Monitors to have been built and deployed before the project was scrapped, actually proved the Monitor concept to be viable to a degree. In response to this, an erratum was published that completely replaces the initial entry in what technically constitutes a [[retcon]] (in the sense of altering canon).

The following is a direct transcript of the official [http://bg.battletech.com/forums/index.php/topic,26137.msg600073.html#msg600073 erratum posting], reproduced here verbatim [http://bg.battletech.com/forums/index.php/topic,28232.0.html with kind permission of the author, Herbert Beas]:

{{quote| Hello,

The following errata applies to the entry titled "Monitors". Please replace ALL TEXT under this entry with the following:
:'''Monitors'''

:'''Outcome Summation:''' Canceled Prototype
:'''Producer/Site:''' [[Blue Nose Clipperships]] of Mars, Sol
:'''Supervising Technician:''' [[Commodore]] Mortimer Basquiz
:'''Project Start Date:''' [[2683]]
:'''Failure Analysis:''' Inefficient Design and Inadequate Infrastructure

:With the advent of the [[compact KF drive]], space became a much more dangerous place. No longer were warships limited to assault DropShips, but they could easily surpass a million tons. Yet, almost half of that mass was still tied up in the KF drive. During the latter part of the twenty-seventh century, a group of [[SLDF]] [[admiral]]s pushed to create a new breed of WarShip, dispensing with the KF drive with the goal of doubling the potential firepower such a vessel could bring to bear. After over a decade of campaigning, funding was finally allocated for project AMHITRITE and Blue Nose Clipperships won the bidding to provide construction for the prototype.

:Though the concept “monitor” was based on the proven hull of the venerable ''[[Avatar (WarShip class)|Avatar]]'' class cruiser, almost immediately problems emerged when the KF drive was removed from the equation. Without the frame around the KF drive acting as the ship’s primary keel, stress analysis revealed that a great deal of additional structural reinforcement would be needed to avoid integrity failure under combat thrust. The design plans were hastily re-drawn and construction resumed, but the structure reinforcements ate away far more mass than originally expected.

:As construction continued on three prototype hulls, the numerous setbacks and additional costs mounted, drawing greater scrutiny from a number of oversight committees. While these monitors had a potential military impact, the potential political impact of their possible failure was orders of magnitudes greater. Internal divisions, even among the Star League admiralty, quickly formed, with pro-monitor and anti-monitor camps ignoring any data that failed to agree with their positions.

:Combat simulations and technical projections won the first victories in favor of the monitors, with most simulations showing overwhelming victories between the heavily armed monitors against larger jump-capable opponents. Unfortunately, these tactical advantages paled in comparison with the logistical studies ordered by Admiral Arthur Ubuntu, who led the challenge against AMHITRITE as the construction effort stretched past eight years without a single prototype emerging from its slip.

:Ubuntu’s studies quickly revealed that, in addition to the greater manpower needs each monitor would need by dint of their extra firepower alone, the support apparatus needed for widespread deployment of monitors would quickly outstrip the Hegemony’s naval resources. This monumental problem primarily stemmed from the monitors’ inability to perform their own jumps. Unbuntu noted that the monitors’ sheer mass—well beyond the scale of the largest DropShips of the day—would force the SLDF to use [[YardShip]]s to transport and deploy each monitor fleet to its duty station, an expensive proposition as any sizable monitor presence in any given system would thus require dozens—perhaps even hundreds—of such jumps, even for the systems nearest to Terra. Counter-proposals to ship monitors in pieces via specialized DropShips for on-site assembly proved equally untenable, as this would still effectively require the YardShips to do the assembly work in any system that lacked shipyards large enough to do the work locally.

:To make matters worse, after disputing computer simulations that underscored the physical dangers of moving monitors in this fashion, Commodore Basquiz, as head of the project, insisted on a “live test”, in which one of the half-completed prototypes would be moved from Mars to [[New Earth]] via the [[J. Swift|SLS ''J. Swift'']], a ''[[Newgrange]]''-class YardShip. After tugboats were needed to get the prototype from its shipyard in Martian orbit to the ''Swift'', the YardShip was damaged during the mooring process and suffered severe structural and drive damage after the jump to New Earth. The damage was so severe that a second YardShip was needed to take the monitor back to Mars, while the ''J. Swift'' needed five months of repairs before she could jump again.

:Convinced of the inability to properly produce, deploy, and maintain a suitable fleet of monitors for local system defense even in the Sol system, the Star League scrapped the monitor project, and ordered the incomplete hulls dismantled. Not a single one of the prototypes ever flew under its own power.

We apologize for the inconvenience.

Thank you,|Herbert Beas}}

==Existing Monitors==
Although the Monitor concept at large was refuted, a few isolated cases exist in canon that could be regarded as Monitors:
*The ''[[Bonaventure (WarShip class)|Bonaventure]]''-class corvette ''[[Sheridan (Individual Bonaventure-class WarShip)|Sheridan]]'', as of [[3067]], operates as a training ship in the [[Sol]] system. It has had its jump drive removed to make room for a full second crew and some training gear; however, it is unknown just how much of the jump drive was removed and how much room/mass the extra facilities take up.<ref>BattleCorps short story "The Last Full Measure"</ref>
*The [[Word of Blake]]'s converted ''[[Naga (WarShip class)|Naga]]''-class [[SDS]] control ships in the [[Sol]] system were effectively monitors.<ref>''Jihad Hot Spots: Terra'', pp. 178–180</ref>
*[[Battlesat]] type space stations with (limited) thrust power could also arguably be described as monitors. It should be noted that they are legal under current construction rules, but have been rendered largely moot due to their limited movement. As a consequence, it is questionable if battlesats were deployed outside of the known canonical example in the [[Luthien]] system.<ref>As explained in [http://bg.battletech.com/forums/index.php/topic,28084.0.html this thread] on the official [[BattleTech forum]]</ref>
*Despite its name, the ''[[Cockatrice]] Monitor Platform'' is technically a DropShip (its design in turn based on a [[Small Craft]], the [[K-1]] DropShuttle); while it could be described as a monitor in a functionality sense, it is not a Monitor in the design sense of being a WarShip without a jump drive core.
