Inaugural was built and launched by the
Winslow Marine Railway and Shipbuilding Company of
Winslow, Washington. She was commissioned on 30 December 1944. Following shakedown off the
California coast,
Inaugural sailed on 14 March 1945 for
Pearl Harbor, where she arrived eight days later. For the next two months, the minesweeper performed patrol and escort duties between
Hawaii and the islands of the western Pacific. She was at
Saipan on 22 May and departed that day with a
convoy bound for
Okinawa, site of the last and largest amphibious operation of the Pacific war. After a voyage enlivened by several attacks on suspected
submarines, the convoy reached Okinawa on 30 May. During the desperate struggle for Okinawa,
Inaugural patrolled the seas around the island group, often firing at Japanese aircraft as they made suicidal efforts to destroy the ships supporting the invasion force. Except for 19–24 July, when the ship put to sea to ride out the great
typhoon,
Inaugural remained in the dangerous waters around Okinawa until 30 August 1945. With the war over, she steamed to the waters around Japan and Korea for minesweeping operations that were a necessary prelude to occupation. She swept the approaches to
Jinsen, Korea, in September, and later cleared mines in waters off
Nagasaki and
Sasebo, Japan.
Inaugural proceeded to Okinawa where she received needed equipment from 14 to 24 October, and then returned to minesweeping around the Japanese home islands. The minesweeper sailed on 24 December for the United States, via Saipan and Pearl Harbor, and arrived at
San Pedro,
California, on 7 February 1946. Sailing again on 11 March, she proceeded to
Galveston, Texas, and decommissioned there on 9 September 1946. She was reclassified
MSF-242 on 7 February 1955.
Inaugural entered the
Atlantic Reserve Fleet, Texas Group, where she remained until struck from the Navy List on 1 March 1967 and sold. Overall,
Inaugural cleared 82 mines and was awarded two
battle stars for service during World War II. ==Museum ship==
