Haste (PG--92), was one of a group of Canadian corvettes turned over to the Navy and manned by the Coast Guard. She was launched as Mandrake (CN--310) by Morton Engineering & Dry Dock Co., Quebec, Canada, 22 August 1942, taken over by the Navy renamed, and commissioned 6 April 1943, Lt. W. A. Dobbs, USCG commanding.
Haste took up regular escort duties following shakedown, making ten voyages to Newfoundland or the Caribbean before November 1944. Small patrol ships such as Haste did much to lessen the effect of U-boat patrols on allied commerce during this critical period of the war. During the period November 1944--May 1945 the corvette served on patrol duty for 10-day periods out of New York. After making two more escort voyages to Newfoundland and return, the ship departed New York 2 July for Charleston where she arrived 3 days later. Haste decommissioned 3 October 1945 and was returned to the Maritime Commission.
