An amphibious assault ship is a type of amphibious warfare ship employed to land and support ground forces on enemy territory during an amphibious assault. The design evolved from aircraft carriers converted for use as helicopter carriers. Modern designs support amphibious landing craft, with most designs including a well deck. Like the aircraft carriers they were developed from, some amphibious assault ships also support V/STOL fixed-wing aircraft and have a secondary role as aircraft carriers.
