Project 11780 Kherson was a 1980s-era Soviet LHD program derived from the Kiev-class aircraft carrier design comparable to the US Tarawa-class amphibious assault ship. The ship would have been about 25,000 tons displacement, with steam turbine power plants and carried about 12 helicopters and four Ondatra-class landing craft or two Tsaplya-class LCACs.^[1] It was cancelled with the fall of the Soviet Union in 1991.
