The Guizhou-class amphibious transport dock is 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 Tian Xia, it has found widespread use in the Canissian Royal Navy, the Shinra Republic Navy, and the Wilkonian Imperial Navy; two modified examples also serve with the Langley Navy, the only known non-MESS operator of the class.
