First purpose-built U.S. helicopter assault ship class lead
mediumUSS Iwo Jima (LPH-2) was the lead ship of a U.S. amphibious assault class built around helicopter-borne Marine operations.
USS Iwo Jima (LPH-2) was historically important because it was designed from the keel up for helicopter assault operations. The ship embodied the Navy-Marine Corps vertical-envelopment concept, using helicopters to move Marines from ship to shore without relying only on traditional landing craft.
