Class Notes:
FY 1944. When the JCS on 10 Nov 43 directed the conversion of 130 APAs (106-235) and 30 AKAs (64-93), the Navy realized that it would also need additional AGCs for completion as early as possible during 1944. With C2's in short supply at both Federal and Moore, which had provided AGC 1-3 and 5, the Navy turned to C2's then building at a new yard, the North Carolina Shipbuilding Co. CominCh on 23 Nov 43 directed the acquisition of eight C2 hulls, the first three (AGC 7-9) to be converted similar to AGC-5, which was a Task Force Headquarters Ship, and the remaining five (AGC 10-14) to be converted with modifications to make them suitable as Task Group Headquarters Ships. Facilities then being provided in AGC's that were not necessary for a task group flagship, such as photographic reproduction and some communications equipment, were to be deleted from the last five ships and the saving in space allocated to useful troop and cargo lift. The Auxiliary Vessels Board ratified these decisions on 4 Dec 43 and recommended the acquisition of the eight hulls. However the MC on 2 Dec 43 agreed to provide only the first three ships, and it took a letter from JCS on 19 Jan 44 to obtain the other five ships.

On 13 Nov 43 BuShips asked if the Philadelphia Navy Yard could undertake some additional AGC design work, because the North Carolina Shipbuilding Co. C2-S-AJ1's had their main bulkheads in a somewhat different location from those in the Federal and Moore C2-S-B1's for which the yard had already produced plans. Philadelphia indicated that it wanted to have a North Carolina hull in the yard for conversion during the development of the plans. By 27 Nov 43 BuShips had decided that Philadelphia would be the design agent for all eight conversions and that it would receive a vessel some weeks before the first vessel arrived at a commercial conversion yard. The three Task Force ships (AGC 7-9) were to be converted at navy yards while the other five would be converted at repair yards in the New York area. Naval ferrying crews transferred the vessels to the conversion yards, AGC 7, 8, and 14 under their own power and the others under tow. AGC 10-13 were all towed north by the large WSA tug TRINIDAD HEAD (MC V4-M-A1 type) assisted by a smaller tug and one or more escort ships.

AGC 15-17: On 29 May 44 CominCh directed that three C2-S-AJ1 hulls be converted to Amphibious Force Flagships in 1945. These were part of a program for the acquisition of 56 auxiliaries, designed to provide for the orderly growth of the auxiliary fleet and replacement of any losses that might be incurred. JCS asked the MC for the 56 ships on 6 Jun 44, and on 22 Jun 44 the MC agreed to provide all but two tankers. On 5 Jul 44 the Auxiliary Vessels Board recommended the acquisition of the 54 ships including AGC 15-17. These were initially to be built by North Carolina and delivered to the Navy incomplete but capable of steaming to their conversion yards, but in December BuShips noted that the hulls were now to be acquired in such an unfinished stage of construction that they would have to be towed to the conversion yards.

On 30 Jun 44 BuShips wrote to CNO that forces afloat in the Pacific, where AGC's were increasingly to be used, had indicated in April that the current AGC design was inadequate for the purposes they had in mind and proposed a considerable increase in AGC facilities and accommodations. The Bureau noted that it had already squeezed everything it could into the current C2 design: personnel accommodations having grown from 130 officers and 738 crew in AGC-1 to 156 officers and 877 crew in AGC-7. There simply wasn't room or stability in a C2 for the 185 officers and 1,000 crew plus the additional deckhouses desired by the Pacific commands, and using a larger hull seemed both unwise because of vulnerability and impossible because of unavailability of hulls. The Bureau therefore recommended a thorough review of the characteristics of C2 size AGC's, focusing on radio, radar, boats, towers, booms, winches, vehicle spaces, guns, internal communications equipment, command spaces, aircraft support control, etc. For example, the Pacific commands did not seem to require aircraft support control, and boats and vehicles could be supplied by other vessels in company. This review presumably led to the numerous differences in external configuration visible in AGC 15-17 compared to their predecessors, including the substitution of a pole mast for the after kingpost pair.
