Attack transport is a United States Navy ship classification for a variant of ocean-going troopship adapted to transporting invasion forces ashore. Unlike standard troopships – often drafted from the merchant fleet – that rely on either a quay or tenders, attack transports carry their own fleet of landing craft, such as the landing craft, vehicle, personnel (LCVP) or Higgins boat.
They are not to be confused with landing ships, which beach themselves to bring their troops directly ashore, or their general British equivalent, the Landing ship, infantry.
A total of 388 APA (troop) and AKA (cargo) attack transports were built for service in World War II in at least fifteen classes. Depending on class they were armed with one or two 5-inch guns and a variety of 40 mm and 20 mm anti-aircraft weapons.
By the late 1960s, 41 of these ships were redesignated with the hull symbol (LPA) Landing Platform, Amphibious, but they all retained their names and hull numbers. [1] [2] [3] [4]
In the early 1940s, as the United States Navy expanded in response to the threat of involvement in World War II, a number of civilian passenger ships and some freighters were acquired, converted to transports and given hull numbers in the AP series. Some of these were outfitted with heavy boat davits and other arrangements to enable them to handle landing craft for amphibious assault operations.
In 1942, when the AP number series had already extended beyond 100, it was decided that these amphibious warfare ships really constituted a separate category of warship from conventional transports. Therefore, the new classification of Auxiliary Personnel, Attack (APA) was created and numbers assigned to fifty-eight APs (AP #s 2, 8-12, 14-18, 25-27, 30, 34-35, 37-40, 48-52, 55-60, 64-65 and 78-101) then in commission or under construction. APA are in the classification of US Navy Auxiliary ships.
The actual reclassification of these ships was not implemented until February 1943, by which time two ships that had APA numbers assigned (USS Joseph Hewes and USS Edward Rutledge) had been lost. Another two transports sunk in 1942, USS George F. Elliott and USS Leedstown, were also configured as attack transports but did not survive to be reclassified as such.
As World War II went on, dozens of new construction merchant ships of the United States Maritime Commission's S4, C2, C3 and VC2 ("Victory") types were converted to attack transports, taking the list of APA numbers to 247, though fourteen ships (APAs 181-186 and APAs 240-247) were cancelled before completion. In addition, as part of the 1950s modernization of the Navy's amphibious force with faster ships, two more attack transports (APA-248 and APA-249) were converted from new Type C4-class ships, the Mariner-class freighters.

Classes of attack transports included:
[7] During World War II, attack transport served in the Pacific Theatre, taking part in many of the Navy's island hopping campaigns. Some attack transports were assigned to the European Theatre, participating in the invasions of North Africa, Sicily, Italy and Normandy. The last use was for the final WW2 Battle of Okinawa. [8] [9] [10] [11]
Despite an impressive assembly of forces, the Aleutian campaign and the Northern Pacific Theater ranked as Admiral Nimitz's third priority in the overall Pacific Theater for receiving materiel and support. As a result, only attack transport (APA) ships were assigned for the assault, without support from any companion attack cargo (AKA) ships. This created extreme logistics burdens for the invasion force because it resulted in considerable overloading of the transports with both men and equipment. To compound problems, these forces were not able to assemble or train together before executing the Aleutian invasion on 11 May 1943. Lack of equipment and training subsequently resulted in confusion during the landings on Attu. [12] [13]
By the end of the 1950s, it was clear that boats would soon be superseded by amphibious tractors (LVTs) and air assault helicopters for landing combat assault troops. These could not be supported by attack transports in the numbers required, and new categories of amphibious ships began to replace APAs throughout the 1960s. By 1969, when the surviving attack transports were redesignated as "amphibious transports" (LPA) (retaining their previous numbers), only a few remained in commissioned service. The last of these were decommissioned in 1980 and sold abroad, leaving only a few thoroughly obsolete World War II era hulls still laid up in the Maritime Administration's reserve fleet. The APA/LPA designation may, therefore, now be safely considered extinct.[ citation needed ]
The 1956 movie Away All Boats presents operations on an attack transport. It was based on a popular novel of the same name, written by an officer who served on one during World War 2. [16]
USS Talladega (APA/LPA-208) was a Haskell-class attack transport of the US Navy. She was of the VC2-S-AP5 Victory ship design type. Talladega was named for Talladega County, Alabama.
A troopship is a ship used to carry soldiers, either in peacetime or wartime. Troopships were often drafted from commercial shipping fleets, and were unable land troops directly on shore, typically loading and unloading at a seaport or onto smaller vessels, either tenders or barges.
Amphibious cargo ships were U.S. Navy ships designed specifically to carry 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.
USS Pitt (APA-223/LPA-223) was a Haskell-class attack transport in service with the United States Navy from 1944 to 1947. She was scrapped in 1980.
Haskell-class attack transports (APA) were amphibious assault ships of the United States Navy created in 1944. They were designed to transport 1,500 troops and their combat equipment, and land them on hostile shores with the ships' integral landing craft.
USS La Grange (APA-124) was a Haskell-class attack transport in service with the United States Navy from 1944 to 1945. She was scrapped in 1975.
USS Joseph Hewes (AP-50/APA-22), formerly SS Excalibur, was a troop transport for the United States Navy during World War II commanded by Captain Robert McLanhan Smith Jr. A part of the Center Attack Group of Admiral Hewitt's Western Naval Task Force, Operation Torch, Joseph Hewes was sunk on November 11, 1942 by the German submarine U-173 in Fedala Roads off French Morocco coast during the Naval Battle of Casablanca.
USS Chilton (APA-38) was a Bayfield-class attack transport. Her task was to deliver troops to the battle front, and to recover and care for the wounded. She served in the Pacific Ocean in the war against the Empire of Japan and returned home post-war with one battle star to her credit.
USS Olmsted (APA-188) was a Haskell-class attack transport that saw service with the US Navy for the task of transporting troops to and from combat areas. She was of the VC2-S-AP5 Victory ship design type. Olmsted was named for Olmsted County, Minnesota.
USS Magoffin (APA/LPA-199) was a Haskell-class attack transport in service with the United States Navy from 1944 to 1946 and from 1950 to 1968. She was scrapped in 1980.

USS Harris (APA-2) was an Emergency Fleet Corporation Design 1029 ship launched for the United States Shipping Board (USSB) on 19 March 1921 by Bethlehem Shipbuilding Corporation, at Sparrows Point, Maryland as Pine Tree State. After operation by commercial lines for the USSB, during which the ship was renamed President Grant and operated commercially until laid up in the late 1930s.
SS President Roosevelt was an ocean liner in service in the 1920s and 1930s. Originally built as a Harris-class attack transport towards the end of World War I, she entered commercial service after her completion. Having been built as Peninsula State, she was soon renamed President Pierce and then President Roosevelt. Requisitioned for service as a troopship with the US Navy during World War II, she was renamed USS Joseph T. Dickman (APA-13) and served in the Atlantic and Pacific theaters, being scrapped postwar in 1948.
The Harris-class attack transport was a class of US Navy attack transport which saw service in World War II. The purpose of any attack transport was to deliver troops and their equipment to hostile shores in order to execute amphibious invasions using an array of smaller integral landing craft. Being intended to serve in forward combat areas, these ships were well armed with antiaircraft guns to protect itself and its vulnerable cargo of troops from air attack in the battle zone.
The President Jackson-class attack transport was a class of seven US Navy attack transport that saw service in World War II.
