The Battlecruiser is a type of terran capital ship employed in the Koprulu Sector. Battlecruisers were employed during the Guild Wars when space engagements were fought by capital ships and medium-sized gunships. The development of anti-capital ship starfighters, such as Wraiths, did not spell the end of battlecruisers. The large warships adapted to carry strike craft which augmented and complemented the combat value of both. Battlecruisers continue to be an integral part of terran space forces as general purpose warships and command ships during extended campaigns.
While there are many classes of battlecruisers, all are armed with lasers and protected by neosteel armor. Gravity accelerators are also found on all battlecruisers.

The Behemoth-class battlecruiser was the most common battlecruiser class and represented the "standard" battlecruiser variant during the Great War. The Behemoth variant is greatly advanced from its Leviathan-class predecessor, featuring the ability to operate within planetary atmospheres and even land on planets. It also features a total of four docking bays (as opposed to hydraulic entry points) which are equipped with force fields, allowing easy deployment of fighters without fear of decompression and greater resilience to enemy boarding actions. Like the Leviathan, it is capable of traveling through warp space, even capable of making jumps within a planet's atmosphere.
Behemoth-class armor consists of the standard neosteel, along with force fields, while armament consists of multiple burst laser batteries (at least 8 around the ship's 'hammerhead')] and a complement of nuclear warheads. Despite the heavy arsenal, Behemoth armament is slightly constricted in that its laser batteries cannot fire at targets to the side and its warheads are reserved for orbital bombardment rather than space combat. A saving grace for the Behemoth-class exists in the form of the Yamato Cannon. One such use of these weapons is that of carrying out a scorched earth policy.
Fighters are an integral component to battlecruiser deployment and the Behemoth-class conforms to this, capable of deploying Wraiths and scoutships to engage the enemy. It also akin to a terran carrier, capable of housing hundreds of soldiers and hardware and maintaining dropships and shuttles for rapid deployment.
The Behemoth-class battlecruiser's Yamato Gun's primary weakness is its huge energy requirements and while the installation of a colossus reactor allows for increased energy storage, it is not a long term solution. The Terran Dominion's Behemoths required access to physics labs to "power up their weapon systems". Should a fleet commander lose access to these accelerators, an entire Behemoth-class fleet could be crippled.
Despite its shortcomings, the Behemoth-class has proven to be an enduring design, keeping up to date with periodic upgrades while its hammerhead design had provided the basis for future classes. Although more advanced classes of battlecruiser have been developed, the Behemoth-class continues to remain in service.

Decided to do this, I found this shot of the Cruiser through a glitch.
