Amphibious cargo ship

Source: Wikipedia, the free encyclopedia.

Amphibious cargo ships were

troops, heavy equipment and supplies in support of amphibious assaults, and to provide naval gunfire support
during those assaults. A total of 108 of these ships were built between 1943 and 1945—which worked out to an average of one ship every eight days. Six additional AKAs, featuring new and improved designs, were built in later years. They were originally called Attack Cargo Ships and designated AKA. In 1969, they were renamed as Amphibious Cargo Ships and redesignated LKA.

Compared to other cargo ship types, these ships could carry

Combat Information Centers
and significant amounts of equipment for radio communication, neither of which were present in other cargo ships.

As amphibious operations became more important in

LCM and LCVP boats with which to attack the beach, and that carried guns to assist in anti-air defense and shore bombardment. Specifications were drawn up, and beginning in early 1943, the first 16 U.S. attack cargo ships were converted from Navy cargo ships
that had previously been designated AK. During the course of the war, 108 such ships were built; many of them were converted from non-military ships, or started out as non-military hulls.

Attack cargo ships played a vital role in the Pacific War, where many were attacked by kamikazes and other aircraft, and several were torpedoed, but none were sunk or otherwise destroyed. Nine AKAs were present at the surrender ceremony in Tokyo Bay on 2 September 1945.[citation needed]

After the war, many AKAs were put into the National Defense Reserve Fleet. Others were converted for other uses, such as oceanographic surveying, undersea cable laying, and repairing other ships.

Some of the reserve ships were recommissioned for service in the Korean War, and some stayed in service during the Vietnam War.

Six more amphibious cargo ships, somewhat faster, larger and of improved design regarding cargo handling, were built between 1954 and 1969: the

USS Tulare (APA/LKA-112) and the Charleston-class
.

In 1969, the U.S. Navy redesignated all its remaining AKA attack cargo ships as LKA amphibious cargo ships. At the same time, several other "A" designations of amphibious ships were changed to similar "L" designations; for example, all the attack troop transport APAs were redesignated as LPAs.

In the 1960s, both the United States Navy and the British Royal Navy developed amphibious transport docks which gradually took on this unique amphibious role and today have assumed it completely. The last amphibious cargo ship in the U. S. Navy, USS El Paso (LKA-117), was decommissioned in April, 1994.
