In the BattleTech universe, the term WarShip refers to starships that combine the capability of faster-than-light (FTL) travel with powerful inter-system thrust engines and heavy weapons and armor. Because of the former capability, they technically fall into the JumpShip category, but unlike these non-combatants, WarShips are geared for space combat. They outclass every common JumpShip and virtually any DropShip by an order of magnitude in size and power.

Description

WarShips could be described as super-large combat JumpShips. However, they do not suffer from the lack of mobility normally associated with JumpShips, instead mounting powerful transit drives enabling them to move through space like DropShips - including combat maneuvering. However, unlike DropShips, WarShips are incapable of atmospheric operations and cannot safely land.

Many, but not all, WarShips have Hardpoints that allow them to carry DropShips with them, further increasing their cargo capacity and combat capabilities.

Construction

Considered the pinnacle of starship engineering, the defining aspect of a WarShip is the use of a Compact Kearny-Fuchida Drive, an expensive component that has only half the mass of a similarly powerful regular Kearny-Fuchida Drive but greater structural integrity, parameters useful for combat but next to useless for regular JumpShips. All ships mounting a compact KF drive core are considered WarShips by default, even if they technically serve in a support role. By contrast, JumpShips with a regular KF core are invariably not considered WarShips; most are non-combattants and the few carrying weapons are usually referred to as Jolly Rogers.

Dissemination

The first designated WarShips in the sense of jump-capable combat vessels were deployed by the Terran Alliance. At the height of the Star League, fleets of thousands of these behemoths roamed the stars, enforcing the League's will. The Succession Wars and subsequent decline into Lostech left no WarShips operative in the Inner Sphere. The last WarShips in the Inner Sphere were believed destroyed during the Second Succession War, all others having fallen prey to combat losses, attrition and maintenance shortfalls save for a number of non-salvageable derelicts and a small hidden fleet secretly maintained by ComStar. Up until the beginning of the Clan Invasion in 3049 they were thought to be essentially extinct.

Clan WarShip fleet

When Aleksandr Kerensky departed the Inner Sphere with his forces they took 1,349 JumpShips with them, escorted by 402 WarShips. Only 260 WarShips are known to have survived the Exodus Civil War; it is estimated that since then, the Clans between them have built anywhere from 50 to 300 more. While each invading Clan fielded 18 WarShips on average in the Inner Sphere, the actual numbers differ wildly from Clan to Clan. During the invasion, Clan Jade Falcon deployed the single largest number of WarShips, fielding 28 in total of which most were Aegis-class. Clan Wolf deployed the smallest number (2 ships).

Inner Sphere WarShip fleet

Following the Clan invasion and the rediscovery of lost technologies, WarShip construction restarted in the Inner Sphere. In October 3056, ComStar's First Circuit decided to allow the sale of transit drives for WarShips (which only the ComStar-controlled Rolls-Royce factories on Terra could produce at the time) to the Draconis Combine and the Federated Commonwealth, while aid from the fanatical ComStar splinter group Word of Blake located drives from derelict ships that the Free Worlds League and Capellan Confederation could recondition and return to a functioning status. Further recovery of lost technology has since enabled most greater powers in the Inner Sphere to field operational WarShips, but only the most industrious of Successor States can construct more than one at a time because of their extreme costs.

Manufacturing

WarShips are the largest class of starship ever built. As such, they are built at orbital docks. They do not differ significantly from other spaceships (DropShips and JumpShips) in operation.

Generally, all later WarShips are equipped with a Lithium-Fusion Battery system. Those that did not include one in their initial design have often been upgraded to carry one.

WarShip Categories

See Also: Canon Warship Overview Like DropShips, WarShips are divided into categories based on their role. Most of these terms have survived since the days of sailing ships, and were updated to reflect the realities of space combat.

• Corvettes - The smallest WarShip category, these craft rarely mass more than 500,000 tons. Lightly armed and armored but extremely swift and equipped for extended tours of duty, corvettes are ideal for commerce protection and raiding.
• Destroyers - More heavily armed than corvettes, these ships perform the same raiding and escort duties, but also serve as guardians of orbital installations. They typically mass between 500,000 and 700,000 tons.
• Frigates - Rarely smaller than 700,000 tons, these ships serve as escorts and picket ships. Usually they are equipped with excellent sensors and are deployed at the edge of a fleet to act as sentries. Frigates also operate as transports, allowing DropShips to dock at their various hardpoints.
• Cruisers - The most diverse ship category in any fleet, vessels in this class are typically further subdivided into light cruisers, heavy cruisers, and battlecruisers.
• Light Cruisers - As their speed is comparable to destroyers and frigates they serve as escorts, raiders, and picket ships, but mount more firepower and armor than the other two ship types. Most cruisers pack enough equipment and supplies to operate away from technical support bases, making them ideal raiders. As a whole, cruisers typically mass between 700,000 and 1,200,000 tons.
  • Heavy Cruisers - Typically these ships trade away some of the light cruiser's speed for additional firepower. Clan toumans typically use these as command vessels.
  • Battlecruisers - These ships are loaded with heavy weapons, but their over-sized engines allow them to remain very nimble and quick in a confrontation, usually sacrificing armor and any other features.
• Battleships - The largest ship class, battleships are easily able to keep pace with frigates and outrun heavy cruisers. Their massive weapon payloads and armor protection ensure that they serve as a fleet flagships, while hitting the most dangerous and determined opposition to break through and create opportunities for their smaller companions to exploit. The pride of the SLDF Navy, the McKenna-class battleship, weighed two million tons, a record that was not broken until Clan Ghost Bear launched the 2.4 million ton Leviathan-class ship.
• Carriers - These are WarShip-sized Aerospace Fighter transports. Principally, there have been few ships dedicated to the carrier role; during the Star League era many navies used hybrid designs that combined the carrier role with another ship type. As a result, carrier tonnages have varied from frigate to battlecruiser size. These dual-role ships were not produced by most of the factions in 31st century during the brief resumption of WarShip production; the one exception was Clan Snow Raven, who produced the Conqueror-class Battlecruiser-Carriers in limited numbers.

Known WarShip Classes
