The USS Alacrity (PG-87) was an Action-class patrol boat designed for coastal defense and patrol duties during World War II. Originally constructed in Collingwood, Ontario, Canada, by the Collingwood Shipyard, Ltd., the vessel was initially built as the British Flower-class corvette HMS Cornel (K-278). The ship was transferred to the U.S. Navy on January 6, 1942, launched on September 4, 1942, and officially commissioned at Collingwood on December 10, 1942. As the second vessel to bear the name Alacrity in the U.S. Navy, she was a vital asset in maritime security during the war. Following her commissioning, the USS Alacrity moved to Sorel, Quebec, by the end of December 1942, where she remained into March 1943. On March 3, she departed via the St. Lawrence River heading toward Boston, Massachusetts. After a brief stop in Quebec on March 5, she spent two months there before resuming her voyage on May 5, arriving at the Boston Navy Yard Annex on May 12. Her shakedown training was conducted in Bermuda waters, which she completed on August 15, 1943. She then arrived in New York City on August 18 and conducted routine voyage repairs and training. Throughout her service, USS Alacrity primarily functioned as an escort vessel, patrolling and screening coastal merchant traffic between New York City and the Caribbean, including destinations such as Guantánamo Bay, Cuba, and Key West, Florida. In May 1945, her operations shifted from the Atlantic Fleet to the Eastern Sea Frontier, where she served along the U.S. East Coast, including Staten Island, New York, and Charleston, South Carolina. She remained at Charleston until she was placed out of commission on October 4, 1945, and was subsequently struck from the Naval Vessel Register on October 24, 1945. Her final disposition was transferred to the War Shipping Administration on September 22, 1947, marking the end of her naval service. The USS Alacrity played a crucial role in safeguarding American coastal waters and maritime trade during wartime, exemplifying the versatile use of corvettes and patrol vessels in the U.S. Navy's World War II efforts.
