USS Might (PG-94) was laid down as Canadian corvette CN-312 by Morton Engineering and Drydock Co., Ltd., Quebec, Canada, on 28 November 1941 and launched as HMS Musk on 15 July 1942.

The ship was transferred to the United States Navy on 20 July 1942, renamed Might on 14 August 1942, and commissioned at Quebec on 22 December 1942.

After fitting out and shakedown from Boston, Might reported to the Eastern Sea Frontier on 10 March 1943 at New York City for convoy escort duty.

Sailing primarily to Cuba and occasionally to Key West, she continued this duty after transferring to the Coast Guard on 27 June.

The protection she provided made it possible for this vital coastwise and Caribbean traffic to continue despite German submarine menace and freed larger destroyer types for the hunter-killer operations which defeated the U‑boats in the Atlantic.
