Grosbeak (AMS-14), was launched as YMS-317, by the South Coast Co., Newport Beach, Calif., 27 February 1943; sponsored by Mre. Marjorie Boutelle; and commissioned 18 November 1943, Lt. John B. Warner in command.
After shakedown, YMS-317 swept the San Francisco Bay area until 3 May 1944, when she sailed for Pearl Harbor. In the Pacific, she acted as an escort vessel to convoys in back and staging areas, such as Eniwetok, Saipan, and Kwajalein, as well as patrolling and minesweeping in these areas. After the war's end, YMS-317 returned to Pearl Harbor for a badly-needed overhaul. She reached Charleston S.C. via San Pedro and the Panama Canal in June 1946 and again underwent overhaul. The ship was named Grosbeak and redesignated AMS-14 18 February 1947.
Grosbeak spent most of her post-war career at the Mine Warfare School, Yorktown, VA., and the Naval Minecraft Base at Charleston as a training ship. She also participated in various experiments at the Naval Mine Countermeasures Station, Panama City, Fla., and engaged in numerous exercises along the coast from New England to the Gulf of Mexico. From 24 February to 19 March 1950 Grosbeak was in the Caribbean to participate in Operation PORTEX out of Vieques Island, P.R., and in February 1951 she became the first of her type to Journey from Yorktown to Charleston via the intracoastal waterway.
