The Neptune-class amphibious assault ships are designed to land forces on hostile shores, and they are the largest vessels of this type in service anywhere in the world. Originally designed by the Shinra Republic, it has found widespread use in the Canissian Royal Navy, the Imperial Byzantine Navy, the Langley Navy, the PeZookian Navy, the Royal Emmerian Navy, the Tian Xia Navy, and the Wilkonian Imperial Navy. There are 6 distinct subclasses currently in use: the original steam-powered version, the nuclear-powered version (also known as the Neptune-class), the gas turbine-powered Fujian-class, the aviation-focused Shaanxi-class, the lengthened Chatham Isle-class, and the angled deck Graf Gustaf-class.

The Fujian subclass is distinguished largely by its use of gas turbine propulsion, resulting in a reduced maintence burden. The Shaanxi subclass has a redesigned, larger hangar deck, with a resultant increase in aviation capability. Additionally, the well deck is deleted, and with it, the ballast tanks have been converted into aviation fuel tanks. The Chatham Isle subclass has been lengthened by a total of 77 feet. It utilizes the enlarged hangar of the Shaanxi subclass while still retaining the well deck. The Fujian subclass is currently being slowly modified to the Chatham Isle standard, at a rate of a ship every year. Completion is projected for 2017. Afterwards, a decision will be made on whether to upgrade the Shaanxi subclass to the Chatham Isle standard. The Graf Gustaf subclass features a similar extension, as well an added angled deck, a bow and waist catapult, and arrestor wires.
