Class Notes:
On 18 February 1958 CNO provided 7.5 million dollars of 1958 funds to BUSHIPS for the construction of two new coastal minelayers (MMCs) for Norway under the Mutual Defense Assistance Program (MDAP). CNO had provided the desired characteristics on 10 January 1958. On 8 April 1958 BUSHIPS responded that there was not sufficient time to complete a new design within the time limits imposed by the use of 1958 funds. In addition a preliminary study indicated that the funds were inadequate for the construction of two new ships. Following a discussion between representatives of CNO and BUSHIPS a study was made of the conversion of the 220-foot MSF hull and it was estimated that this conversion could be accomplished within the funds available. The 220-foot steel hulled AUK-class minesweepers (AM) had been reclassified to MSF with all other AM's on 5 February 1955. BUSHIPS attached the resulting plans and characteristics to its letter of 8 April 1958 and requested CNO to approve them, and it also informed CNO that it intended to assign the work to the Charleston Naval Shipyard. The Bureau therefore asked that CNO designate two ships with similar propulsion plants from the reserve fleet, preferebly from a location near Charleston. The characteristics provided for 94 MK 6 mines, all under cover, and an armament of one 3"/50 single and two 20mm twin gun mounts and a MK 63 gun fire constrol system. The detail specifications were based on earlier ones for the conversion of minesweepers (MSF) to patrol craft (PCE). This was probably a reference to SCB 143 dated 6 April 1955, which was developed for MDAP as the cheapest way of getting coastal escorts.
MSF 117 and 119, were redesignated Coastal Minelayers MMC 1-2 effective 30 November 1958 and a third ship, MSF 323, was redesignated MMC 3 on 4 December 1959. These three were converted to coastal minelayers by NSY Charleston. A fourth ship, MSF 112, was converted to the same design under the offshore procurement program at the main Norwegian navy yard at Horten. The main deck aft of the original forecastle was enclosed and fitted as a mine deck with 60 to 90 mines stowed on and launched from three rails. The ships were also fitted for anti-submarine warfare with sonar, two Hedgehog projectors, one depth charge rack suspended over the mine rails at the stern, two K guns, and in ULLER a Norwegian Terne III ASW system.
