Class Notes:
Six relatively late LSM's were designated on 10 April 1951 for conversion and transfer under the new Mutual Defense Assistance Program (MDAP): LSM 481, 484, 490, 492, and 493 to Turkey and Norway as coastal minelayers (later called the MMC 6 class) and LSM 500 to Denmark as a Motor Torpedo Boat Tender (listed here as an AGP). LSM 481 began conversion on 2 February 1952 and the other four minelayer LSMs began conversion four days later, all five at different commercial yards. All were initially to be completed on 1 August 1952 and were actually delivered on 6 October 1952. Two minelayer LSMs for Greece were added to the program in early 1953 and two for Norway in mid-1953. The converted LSMs were all stricken by the USN before being transferred, but they remained in the Naval Vessel Register (NVR) as LSM's in MDAP loan status. Following the creation of the coastal minelayer (MMC) category for the Norwegian GOR class minesweeper conversions in 1958 (MMC 1 class) and the Danish FALSTER class new construction ships in 1960 (MMC 4 class), the minelayer LSMs were assigned MMC numbers in place of their original LSM designations as of 1 Oct 1960 while remaining stricken, with the FY 1953 units (MMC 6-9) being numbered before the FY 1951 units (MMC 10-14).

The ships had two minelaying rails on the former LSM vehicle deck and four booms (two forward, two aft) for loading mines onto them. The redesigned topside area was crowded with anti-aircraft guns. A Greek source gives the capacity of the Greek ships as 100-130 mines and a Danish source gives the Danish ships 98 Mk I mines.
