USS Ardent (AM-340)

The second USS Ardent (AM-340) was a Auk-class minesweeper in the United States Navy.

Ardent was originally laid down as HMS Buffalo (BAM-8), for the Royal Navy on 20 February 1943 at Alameda, California, by the General Engineering & Drydock Co.; rescheduled for delivery to the United States Navy; renamed Ardent and redesignated AM-340 on 24 May 1943; launched on 22 June 1943; sponsored by Mrs. Bernadette Armes, the daughter-in-law of George A. Armes, President of the General Engineering & Drydock Co., and commissioned on 25 May 1944, Lt. Comdr. Allan D. Curtis in command.

World War II Pacific operations

During the first seven months of her career, Ardent escorted convoys and ships operating between the west coast of the United States and the Hawaiian Islands, though she also ranged as far as Eniwetok in the Marshalls and Tarawa in the Gilberts.

Sinking of the Japanese submarine I-12

The highlight of her service during this period occurred on 13 November. Ardent and the frigate USS Rockford (PF-48) were escorting a six-ship convoy midway between Honolulu and the United States. At 12:32, Ardent's sonar picked up a submarine contact. Ardent attacked first at 12:41, firing a 24-charge "hedgehog" pattern, and again at 12:46 with a second "hedgehog" pattern. Rockford left her escort station to assist, and fired her first barrage of rockets from her "hedgehog" at 13:08; two explosions followed, before an underwater detonation rocked the ship.
