Martian Battleship Deimos

Built by the Mariner Naval Yard, the Deimos was a joint effort between Koslovic Martian governments in the lead up to the Interplanetary War. Meant to provide a formidable defense in the event of imperialist aggression from Earth. The Deimoswas considered an orbital control vehicle by the Koslovics and generally falls under the heaviest class of orbitor space vehicles. (Although modern parlance has seen the Deimos called a battleship).

Emblematic of Koslovic design philosophy, the Deimos was inventive in its construction and considered a testament to Martian ingenuity. Built in pieces, the Deimos is modular in design, with only the central frame being constructed as one piece. With various modules being added as they were completed, this allowed the parallel construction of many of the ship's systems and its rapid assembly shocked observers on Earth. This would come at a cost; however, the integration of the modules would prove to be a nightmarish task. It’s fitting out and commissioning taking far longer than anticipated. To the point her sister ship, Phobos would be commissioned only a few months after, learning from the problems Deimos faced.

Deimos and Phobos would both be vital for the defense of Mars from the imperialist UN and counter-revolutionary Friedens. With both seeing action in the IPW, usually used to subdue various holdout stations around the Maritain sphere of influence. Including participating in the siege of station Relentless. However, Deimos and Phobos would be pulled away for preparations in dealing with the UN taskforce sent to subdue Mars. Only Deimos however would see combat as Phobos would be disabled by a daring raid in November 2163. Conducted by the UNSC's special forces and infiltrators. Deimos herself would engage the UN taskforce in early December and being destroyed on the 6th by an overwhelming attack.
