Class Notes:
FY 1942 (APA 57-75), 1944 (others). On 8 Aug 42 the loss of a combat loaded transport, GEORGE F. ELLIOT (AP-13), off Guadalcanal underlined the risks of having too many troops and supplies in a single large hull. (This lesson was reinforced in November by the loss of five combat loaded APs and the disabling of a sixth in the Northern Africa invasions.) An additional problem with large transports was that no shipbuilding ways capable of building them to Navy designs would be available before 1 Aug 44. On 30 Sep 42 CominCh sent to VCNO tentative specifications for "small combat loaded transports" and "small combat loaded cargo vessels" and asked for preliminary designs. His 5,000-ton, 380-foot (wl) AP was to carry 30 officers and 600 troops (about half of a combat team), with 60,000 cubic feet of cargo at a sustained speed of 15 knots and was to have two sets of Welin davits per side and room for 15 landing craft. The AK was to be of the same size and speed but with more cargo and less troop capacity. BuShips submitted a preliminary design for the AP on 1 Nov 42.

On 28 Dec 42 CominCh referred to the JCS a program for 32 AP's and 32 AK's of the small combat-loaded type, pointing out that the converted ships then being used were too large (requiring excessive time for unloading), carried more troops than desired in individual combat units (concentrating troops and materials too much on the assault line), and had too much draft for use in many places where campaigns might take place. CominCh added that Navy officials, after considering a large transport design produced in September 1942 based on the DIXIE (AD-14) class of destroyer tenders, the intermediate DOYEN (AP-1) type (which also carried more troops than desired in a combat unit and had three feet too much draft), and the new small type, were unanimous in regarding the small type as the one "most suitable to all types of military requirements." The number of ships in the program was based on a calculation that the Navy would need 32 each of the small AP's and AK's to replace the 22 large APs and 8 large AKs that it expected to lose in 1943 and 1944. (A large AP had about 14/9ths the capacity of the small one while a large AK had about 4 times the capacity of the small type.) The Navy proposed that the Maritime Commission build the vessels.

On 8 Jan 43 the JCS approved the program for 32 small AP's and 32 small AK's and asked the MC if it could build the ships. The MC agreed on 17 Feb 43 and, upon receipt of a JCS directive of 25 Feb 43, contracted for the ships under its Military Program. The MC produced its S4-SE2-BD1 design, enlarged it to accommodate the only main propulsion machinery that was readily obtainable (a twin-screw turbo-electric plant), and presented it to the Navy on 25 Feb 43. This final design provided for a 6,000-ton, 400-foot (wl) APA that would carry 46 troop officers, 800 men, and 60,000 cubic feet of cargo at a sustained speed of 16.5 knots on a draft of at most 15.5 feet. The same hull and machinery designs were used for the AKA-21 class. On 10 Jan 44 the Auxiliary Vessels Board recommended acquiring the ships by transfer of title from the MC upon their completion. The ships were formally acquired by the Navy from the MC one day before commissioning except APA-58, 65, 66, and 83 (on commissioning date) and 72, 74 and 87 (2 days before commissioning). The tonnage of APA 57-75 was charged against the 1799 Vessels Emergency Construction Act of 6 Feb 42, hence their early FY date.

All except APA-72, 76, 78, 80, and 84 went to Pearl Harbor in early 1946 for use in the Bikini atomic bomb tests (Operation Crossroads). Of these 27 ships, two were sunk in the first test, twelve remained afloat but damaged and radioactive in the target array and were towed to Kwajalein for decommissioning, assessment and subsequent sinking, seven were present at Bikini outside the main target array and were re-manned after the test and remained in service, and six were decommissioned at Pearl Harbor before the tests. APPLING (APA-58) was selected in late July or early August 1946 to be the "detector vessel" for a third test at Bikini (Test Charlie). She was to be fitted as LSM-60 had been for the second test to lower the bomb in a pressure chamber (a spare submarine conning tower) to the depth at which it would be detonated. Like LSM-60 she would have disappeared in the explosion, but Test Charlie was cancelled.
