On 24 February 1941 the MC ordered six ordinary cargo ships of the C2-S-B1 type (MC hulls 183-188) from the Moore Dry Dock Co. in Oakland, Cal., but before delivery it was decided that a group of refrigerated vessels was required to carry frozen meat to Allied forces. These six ships were therefore converted while building with refrigerated holds and the suffix (R) was added to their designation. Following the success of these ships six more ships (MC hulls 1202, 1205-07, 1210, and 1212) were selected from a large group of C2-S-B1 cargo ships ordered from Moore on 11 June 1942 and were built, instead of being converted, as reefer ships with full refrigerated capacity and intended for permanent use after the war. All six of the C2-S-B1(R) ships and four of the six R2-S-BV1 ships ended up in the Navy after the war.
On 18 March 1946 the Auxiliary Vessels Board received a request from the DCNO for Operations (OP-03) for the Navy to take title to two MC-built refrigerated cargo ships, OCEAN CHIEF and GOLDEN ROCKET, to be manned with the crews of two smaller ADRIA (AF 30) class AFs. This request was based on post-war requirements for two fast, fully-refrigerated ships for point to point transportation of frozen provisions to Pacific bases. In its report No. 105 of 29 March 1946 the Board noted that the two ships were then under allocation to the Navy operating with merchant crews. The allocation had to terminate on 30 June 1946 to avoid payment of charter hire. The Board was informed that sufficient personnel to man the ships could not be realized by decommissioning two of the small ADRIA (R1-M-AV3) class ships but that one ADRIA plus SATURN (AF 49), a former German ship with special type boilers that would be expensive to replace, would provide enough men. The Board therefore recommended that title to the two ships be acquired by the Navy from WSA before 30 June 1946 and that they be manned by minimum naval crews sufficient only for operation in the transportation of bulk refrigerated cargoes for the logistic supply of bases. The expense was charged to a wartime program, Program 45c of FY 1944.
As acquired ALSTEDE and ZELIMA, MC Design R2-S-BV1 ships, had single-temperature (15 degree F) open hold reefers without insulation between levels of the holds and suitable only for carrying refrigerated cargo like frozen meat in bulk for complete discharge by holds. They could only handle the split cargoes needed for fleet issue (zero degrees F for quick frozen foods and 30 degrees for chilled items) through extensive modifications, including the installation of insulation on transverse watertight bulkheads, and their centrifugal type compressors could not provide the necessary zero degree freeze temperature. On 10 May 1948 Commander, Service Force Pacific recommended that they be converted for fleet issue in two phases, the first phase to provide for issuing at sea and the second to make them fleet issue ships. Although BUSHIPS advised in 1948 that there were then no funds available for such conversions, the conversions had been carried out by mid-1950. In contrast to later fleet issue ships, ZELIMA's Replenishment Handbook (ca. 1960) warned that she was not equipped with modern, time saving cargo handling equipments such as fork lift trucks, vertical lift conveyors, etc., and that it took about twelve hours to break out a normal load for a crarrier task group, the last four hours being devoted to the break out of chill and freeze items.
AF 50-52, C2-S-B1(R) ships, were among the Army ships operating out of continental US ports that were to be acquired on 1 Mar 1950 for which names, classification, and hull numbers were approved on 21 Feb 1950. GOLDEN EAGLE had been in Army service from 1948 to 1950. They would have been used in point to point service (until 1960 for AF 52).
On 5 September 1950 BUSHIPS directed that GREAT REPUBLIC, a C2-S-B1(R) refrigerated cargo ship with characteristics like ALSTEDE, be transferred from MARAD (MA) for active service in the Navy's operating forces and be converted similarly to AF 48 and AF 49 with facilities for 13 officers, 19 CPOs and 100 other enlisted, a reefer plant modified to permit split operation, and an armament of ten 20mm twin mounts with all other guns removed. GREAT REPUBLIC was named PICTOR for a constellation and designated AF 54 on 18 Sep 1950. She was delivered to NSY Mare Island on 13 September 1950 and commissioned on 18 October 1950. She served as a fleet issue ship.
The SCB first proposed characteristics for a full conversion of a C2 cargo ship to a store ship (reefer), SCB Project No. 57, in a memo of 22 April 1949. An AF conversion (AF 55, SCB Project No. 57) was included in the First Supplemental FY 1951 Shipbuilding and Conversion Program along with an AKS (SCB 49) and an AOR (SCB 50) conversion. The SCB forwarded its final recommended characteristics for the AF to CNO on 16 October 1950, and CNO approved the SCB characteristics for all three FY 1951 conversions and forwarded them to BUSHIPS and BUORD by letter on 27 October 1950. Major alterations for the AF listed in October 1950 included the replacement of the existing open hold centrifugal blower type compressors with Navy Standard reciprocating reefer machinery suitable for "fleet issue" and the installation of insulated hatch trunks and brine coil cooling in isolated boxes. On 6 December 1950 CNO informed BUSHIPS that SS MATCHLESS (R2-S-BV1) had been designated as the AF and WACCAMAW (AO 109) as the AOR. New York SB Corp. was awarded a contract on 22 Dec 1950 for the conversion. On 16 January 1951 the Navy approved the name ALUDRA and designation AF 55 for SS MATCHLESS. In accordance with the SCB characteristics, ALUDRA was listed in April 1952 with an authorized armament of 6-3"/50 twin mounts (not yet installed), and in April 1955 she was listed with the six mounts installed including two on the amidships superstructure, probably in the upper bridge wings. However rigging, kingposts and booms interfered with the arcs of fire of these amidships guns and for this reason they were soon removed. In addition space for gun magazines, ready service rooms, etc., was more readily available near the bow and stern. Photos in Febuary 1956 show the ship with only four twin mounts, two at each end. See TULARE (AKA 112) for a larger auxiliary that kept 6-3"/50 twin mounts.
SIRIUS, ex TRADE WIND, a C2-S-B1(R), was ordered in May 1956 to be acquired as a steam-powered replacement for POLARIS (AF 11), which was powered by by an unreliable main propulsion diesel and needed an overhaul. POLARIS had been serving as a testbed for improved underway replenishment gear, and the funds for her overhaul were used instead in the Triple A Yard in San Francisco to transfer her UNREP booms and winches to SIRIUS. SIRIUS became a commissioned USN ship with no gun armament and conducted UNREP trials beginning in 1957 and culminating in April 1959 in trials with PASSUMPSIC (AO 107)for the development of the FAST (Fast Automatic Shuttle Transfer) UNREP system that became a key feature of the AOE 1 class. SIRIUS was also the first in this group of C2 reefers to be disposed of.
On 13 September 1961 effective 13 October 1961 the name of AF 52 was changed from GOLDEN EAGLE to ARCTURUS and she moved from MSTS to commissioned status with the active fleet. At the same time the newly acquired FLYING SCUD (MC 188, C2-S-B1(R)) and FLEETWOOD (MC 1207, R2-S-BV1) were renamed and reclassified PROCYON (AF 61) and BELLATRIX (AF 62), both as commissioned store ships. The single 3" gun attributed to them in 1961 was probably displaced by a helicopter deck, and these three commissioned ships were also effectively unarmed.
