The Invader class carrier is a large carrier class produced by Proteus Designs. Proteus Designs had been able to do with the Invader class as it had done with the Black Panther, Black Panther II class destroyer, the Dragon, the Huron class battleships, and the Sterling and Destiny class battlecruisers. That is, it produced a ship class that shared similar components to allow for faster production and repair of the ships.  The Invader class was not just an elongated Aggressor Class that Proteus stretched out over 1,000 meters to make for some more deck space like Galacia Designs did with the Insurrection design to produce the Illustrious class carrier.  The Invader class showed a whole new way thinking about carrier development.  The Invader class had all the innovations of the Aggressor class, including the phalanx weapons, and could handle more than a third more fighters than the Aggressor class, and even more in wartime.

The Invader class carrier also had the main gun complement of a heavy cruiser or battlecruiser and Proteus gave the Invader class the shields and hull armor to match up. While the Invader Class saw very little action in the Second Sabor war, its development brought a new direction of carriers in the battle theatre. The Invader class carrier was the heaviest carrier to date and it was a next step in the combination of a battleship and a carrier. It was a ship that could yield heavy guns as well as squadrons of fighters. It was this line of development that brought about the Nebula class space control ships, as well as the Behemoth class ships.  It was a glimmer of the direction of things to come with the Heavy Battlecarrier.
