Class Notes:
AP 193-195 were among 18 Maritime Admiminstration ships to be transferred to the Navy for which names, classification, and hull numbers were approved on 31 Jul 1950.

SECNAV on 7 Feb 1951 wrote to the Secretary of Commerce that an urgent requirement had developed to provide additional trooplift for the armed services which could not be met by the transports currently assigned to MSTS. The Navy had determined that the requirement could be satisfied initially by the acquisition of five C4 type transports. SECNAV therefore requested that MA transfer title to and possession of five of these ships to the Navy. On the next day Commander MSTS authorized COMSTSLANT and COMSTSPAC to accept delivery of these ships from MA and to activate them for operation by 1, 5, and 10 April for the three ships on the East Coast (including GEN OMAR BUNDY, AP 152, and MARINE CARP, AP 199) and by 20 and 25 March for the two ships on the West Coast (MARINE SERPENT [name and hull not stated] and MARINE CARDINAL (same, although if extensive repars were required to the main engines of the latter, GEN O H ERNST, AP 133, was to be substituted)). The ships were to be activated to provide maximum troop capacity. On 12 Feb 1951 MSTS headquarters cancelled this directive promising further instructions later. On 12 February 1951 Commander MSTS recommended retaining the names and assigning the bow numbers AP 199 to MARINE CARDINAL (Pacific), AP 200 to MARINE JUMPER (Atlantic), AP 201 to MARINE MARLIN (Atlantic), and AP 202 to MARINE SERPENT (Pacific). On 23 February 1951 the Navy requested that this acquisition be held in abeyance and instead recommended that some of these ships should be withdrawn from the NDRF and after essential repairs by the MA that they should be maintained in a ready status.

On 30 January 1952 Commander MSTS wrote to MARAD that the Navy's Program Objectives for FY 1953 included a provision for the acquisition of four C4 type transports for assignment to MSTS and conversion to full troop capacity. The Navy asked that MA authorize MSTS personnel to board MARINE CARP, MARINE JUMPER, MARINE MARLIN, and MARINE SERPENT to survey them and prepare specifications for bids for the conversions. On 13 March 1952 SECNAV wrote to MARAD that it had now been determined that four transports of the C4 type (in addition to T-AP 193-195) were needed by the Navy for transfer to MSTS as replacements for the six VC2 (Victory) type transports (T-AP 187-192) then in service. It was planned to return the six VC2 vessels to MA when replacement had been made. The Navy therefore requested transfer of MARINE CARP, MARINE JUMPER, MARINE MARLIN, and MARINE SERPENT (T-AP 199-202). MARAD agreed on 25 March 1952.
