Class Notes:
FY 1944. On 24 Jul 43 CominCh/CNO (Admiral King) ordered the acquisition of two ships suitable for use as General Stores Issue Ships (AKS), and on 3 Aug 43 the Auxiliary Vessels Board recommended the acquisition of two Maritime Commission C2-S-AJ1 type cargo ships then under construction at the North Carolina Shipbuilding Co. for this purpose. A few days later the Planning Officer of the Naval Transportation Service (NTS) noted in a memo to OpNav that the head of the Maritime Commission had just pointed out that the demands made by the Army and Navy for C2 and C3 type ships exceeded the presently scheduled program. This was caused primarily by intense demands for troop transports, AKAs and APAs. The NTS memo then pointed out that the current (1943) program called for the conversion of EC2 (Liberty) cargo ships to troopers because of the unavailability of faster C2 and C3 hulls and argued that the faster ships should be used for missions that involved frequent movements within forward areas while slower types like the EC2 should be used for types like stores issue ships and repair ships which spent much of their time in bases. The memo noted that employment studies showed that speed and hull size had contributed little to the wartime value of ships like POLLUX (both AKS-2 and AKS-4) and three tenders, VULCAN, DOBBIN, and ALCOR, while the same studies showed that one C2 or C3 hull was worth three EC2s as a troop carrier. The issue was debated during September, with the result that on 29 Sep 43 the Maritime Commission approved the transfer of two EC2 hulls to AKS 5-6. According to the history written by one of the later ships (AKS-12) the conversion of these ships consisted primarily of the addition of two extra 'tween decks in holds 2, 3, 4, and 5 plus minor alterations in other compartments and the installation of standard Navy equipment such as radar.

On 22 Sep 43 CinCPac approved and forwarded a request by ComAirPac that five additional General Stores Issues Ships be provided for the Central and South Pacific areas. On 22 Oct 43 the Auxiliary Vessels Board noted that part of this requirement would be filled by the conversion of ARG 14-15 to Aircraft Engine Overhaul and Structural Repair Ships, ARV 1-2, and recommended the acquisition of three EC2 hulls to fill the remainder of the requirement. (See AVS 1-2 for more on this requirement.) The Navy selected as AKS 7-9 three ships then under construction at Houston, Texas (MCE hulls 1958, 1960, and 1963) but soon agreed to accept instead three ships (MCE-952, 2012, and 772) that were due to arrive soon at Mobile, Ala., with cargoes of bauxite. A ship that had just been completed at Panama City, Florida (MCE-1528) was however immediately substituted for MCE 952 as AKS-7. All three ships were moved to Tampa, Florida, for conversion.

Almost a year later, on 3 Aug 44, CinCPOA approved and forwarded a request from ComServPac for six more AKS for supporting operations in the Pacific. On 4 Sep 44 CNO asked the Maritime Commission to provide the ships, and on 22 Sep 44 the Auxiliary Vessels Board recommended acquisition of the vessels. Once again, to avoid jeopardizing the APA-AKA-AGC programs, all of which used C2 and C3 hulls, EC2 hulls were used for the six additional AKS. The conversions were distributed among five shipyards, Tampa Shipbuilding being designated as the lead yard. The conversion of AKS-13 was assigned to Savannah Machine & Foundry Co., Savannah, Ga., but was reassigned on 24 Nov 44 to the Norfolk Navy Yard.

The entire class was among 30 EC2 (Liberty) type auxiliaries selected by CNO in November 1945 for use in "special explosive tests." Thirty VC2 (Victory) type APAs of the HASKELL (APA-117) class were also selected, along with many older combatants. In November CNO ordered the AKS-5 class ships to proceed to Pearl Harbor and decommission there pending the tests. The ships were deleted from the plans for CROSSROADS (the Bikini atom bomb tests) in February 1946, a month after the VC2s were replaced in the target list by less valuable ships of the GILLIAM (APA-57) class. The Commandant, 14th Naval District (Hawaii) then asked that the AKSs be moved to the West Coast to avoid berthing inactive ships at Pearl. Ten of the ships were decommissioned at Pearl between March and August 1946 and were finally towed to San Francisco for disposal in 1947. The one exception was AKS-13, which served as a supply ship throughout CROSSROADS and remained in commission until steaming from Pearl to San Francisco in early 1947 for disposal.
