The Dezarium War was a brief but devastating conflict fought in 2205 between the Great Garmillas Empire, with the support of the Earth Federation's 65th Escort fleet, and a mysterious alien force known as Dezarium.

Superweapons and Battleships

The Calaklum-class is a heavy battleship measuring 520m in length. The design of its hull is very different from other gatlantis ships, giving it a unique operative function. Alongside more traditional weaponry, it is equipped with a Lightning rotation gun, a firing system which uses a ring of small torpedo bits that amplify the beam energy when fired. In addition, its firepower can further be increased by supplying a large amount of lightning strike bits from multiple ships of the same type. When put together various Calaklum-classes can assemble a Legionairre Cannon or an Inferno Cannon, two incredibly devastating weapons capable of destroying a vast number of ships or even entire planets. However, firing them results in destroying the ships that assembled them.
The Gostok-class is one of the largest and most heavily armed warship classes to serve in the Gatlantean army it's equipped with two ultra-giant missiles on the bow capable of annihilating entire enemy fleets, which can be replaced by other warheads or even by landing pods depending on strategic demands. The battleships of the class are also armed with 29 other missiles as well as 2 beam turrets and 7 hybrid turrets capable of shooting both beams and missiles. The Flame Strike Gun becomes even more destructive when it is paired with two instant matter transporters, built from Garmillan experimental designs.[8][10] The weapon is fired directly into a field projected by the matter transporters; the cannon's discharge is teleported toward a target, allowing the Medalusa to stay out of enemy weapons range while potentially giving it an added element of surprise.
Medalusa battleships are warp capable. Fighters take off and land from a V-shaped flight deck on the top aft section. Ships of the class can be adapted into massive tanks for ground actions, with removal of their Flame Strike Guns and matter transporters. In this configuration, the upper hull can be mounted with a reflection satellite cannon. Although Medalusa vessels are typically crewed by Gatlantean soldiers, tank versions can be fully operated by artificial intelligence systems.
