As you may have guessed from the fact that this is a pixel deviation drawn in the style of a famous ship lineart website, this is for my Nationstates country, Birkaine.
More specifically, it's the main workhorse of the Birkainian Naval Aviation, the huge Troika-class catamaran carrier accomodating 110 rotary- and fixed-wing aircraft of various types while not sacrificing its own armament, as it is equipped with 24 launch tubes for P-700 missiles, as much as an Oscar-II class submarine. It posesses extensive command facilities given that these carriers are generally in charge of the integration of the entire air defense grid over a fleet, as the navy is composed mostly of arsenal ships, which possess very heavy armament but don't have much in the way of sensors to target multiple enemmies or coordinate with one another to avoid overkill or targets slipping by. The large island is built in the middle of the two hulls of the ship, which is propelled by two nuclear reactors. Wherever one of the 23 Troikas currently serving is deployed, they act as flagship for other task forces such as amphibious assault groups and missile ship task groups. It has a displacement of 135,000 tons.
Scale is by shipbucket, needless to say. I used several bits and pieces belonging to other people to smoothen the process of drawing this, such as the aircraft elevators by McConrad's Ulyanovsk-class and the boat docks by Alvama.
