Class Notes:
FY 1944. On 25 Jun 43, when approving the report of the Auxiliary Vessels Board that provided for the construction of AE-13, CominCh added a directive the acquisition and conversion of two more C2s to help fill the burgeoning need in the Pacific theater for ammunition ships. On 15 Apr 44 CominCh directed the acquisition of two more AEs for the Pacific, noting that operations scheduled there for late 1944 and in 1945 would take place at much greater distances from Pearl Harbor and the continental United States. In arguing for more Navy-operated AEs, he wrote that "the present use of merchant cargo vessels to carry part of the Fleet ammunition supply is dangerous, due to lack of refrigeration and special handling and stowing facilities. It is also inefficient as mixed cargoes cannot be carried and ammunition must be transferred to Navy manned Ammunition Ships for further issue to the Fleet." On 6 Jun 44 JCS requested that the MC modify its building program for the first half of 1945 to provide for the construction of 56 merchant type vessels as Naval auxiliaries. The MC on 22 Jun 44 agreed to supply 54 ships, including four more AEs, and the Auxiliary Vessels Board approved the program on 5 Jul 44. The four AEs were to be delivered to the Navy by their builder incomplete but capable of steaming under their own power for conversion by the Navy similar to the procedure used for AE 14-15.

For AE 11-12, the Navy and the Maritime Commission turned to a new variant of the C2 design and a new shipyard. The C2-S-AJ1 differed from the standard C2 in that it was of the full scantling rather than the shelter deck type, with a greater maximum draft and higher gross and deadweight tonnages. All C2s of the AJ type were built by the North Carolina Shipbuilding Co. of Wilmington, N.C., a wartime yard built and operated by the Newport News Shipbuilding and Drydock Co. The availability of conversion plans for the AJ type caused the Navy to return to this yard for AE 14-19. In November 1944 the Navy added to the conversion specifications features to make the ships capable of transferring ammunition (including aircraft bombs) while underway at sea. All of these ships were delivered in an incomplete status but capable of steaming to conversion yards under their own power. AE 11-12 were to carry 1-5"/38 and 2-20mm guns on the ferry trip, but AE 16-19 were to make the trip unarmed.

The first ship of this class was lost in a cataclysmic explosion after only a little over four months service. At the time of the accident, the ship was acting as an ammunition depot, both receiving and delivering ammunition to other ships and lighters simultaneously from all five holds of the ship. An official analysis of her loss, promulgated to the fleet on 15 Aug 45, noted that the explosion originated within the ship and described numerous unsafe conditions and practices on board that were revealed by the investigation.

Although these ships, and those of the previous LASSEN (AE-3) and MAUNA LOA (AE-8) classes, became ubiquitous in the Navy of the late 1950s and the 1960s, their value was apparently not fully appreciated during the massive post-World War II demobilization. When the Korean War broke out in 1950, all but two of them (MOUNT KATMAI and GREAT SITKIN) were out of commission in reserve. Much of the ammunition resupply to the fleet during the early part of this war was carried out by AKAs of the LIBRA (AKA-12) and ANDROMEDA (AKA-15) classes. Two of these, VIRGO (AKA-20) and CHARA (AKA-58), served again as ammunition ships during the Vietnam War.
