USS Muir (DE-770) was a Cannon-class destroyer escort built for the United States Navy during World War II. She served in the Atlantic Ocean and provided escort service against submarine and air attack for Navy vessels and convoys.

She was named in honor of Kenneth Hart Muir who was posthumously awarded the Purple Heart and the Navy Cross for his "outstanding courage and unselfish devotion to his men" when he went down with his ship after getting his men off before it went down.

Muir was laid down by Tampa Shipbuilding Co., Tampa, Florida, on 1 June 1943; launched on 4 June 1944, sponsored by Mrs. Witten H. McConnochie, sister of the late Lieutenant (jg.) Muir; and commissioned on 30 August 1944, Lt. Comdr. Theodore A. O’Gorman, USNR, in command.

World War II North Atlantic operations[edit]

Following shakedown off Bermuda, British West Indies, Muir operated as school ship in the Chesapeake Bay area from 16 November into December. On 9 December she sailed for Europe, arriving off Gibraltar the 26th to begin a year of convoy duty between the east coast and Mediterranean ports. She also served as part of a "Killer Group," Task Group 22.13, so called because the primary duty was to hunt and destroy enemy submarines. Towards the end of the European war, Muir operated with Task Force 63 which stymied the German U-boats' final thrust against Allied shipping in the North Atlantic.

End-of-War activity[edit]

When the news of Germany's surrender was received on 8 May 1945, Muir and her group began locating German submarines to accept their surrender. On 10 May she and Carter (DE-112) approached German submarine U-858 through a dense fog, her black flag of surrender barely visible even at close range. She was turned over to two other escort ships for delivery to a U.S. port.

On 17 May Muir joined Sutton (DE-771) in escorting under guard publicized U-234, with high ranking Luftwaffe officers and men German civilian technicians on board, to Portsmouth, New Hampshire, arriving two days later. The escort ship continued on to New York City, mooring the 20th.

Post-War stateside duties[edit]

From 14 June Muir operated off Mayport, Florida, with Guadalcanal (CVE-60), training carrier pilots for Pacific duty until Japan surrendered in mid-August. On 27 August she departed Mayport for Charleston Navy Yard, Charleston, South Carolina, arriving a day later.

After visiting Houston, Texas, for Navy Day on 27 October, she devoted November and December to a cruise testing "SOFAR," a new long-range air sea rescue method. She traveled 7,500 miles in the Atlantic dropping bombs for naval ships in the Bahamas to pick up the sound waves and plot the position of the destroyer escort as far away as Dakar, French West Africa (now Senegal).

In March 1946 Muir reactivated and was assigned to the Operational Development Force, with Norfolk, Virginia, as her homeport, for service into late 1947.

Decommissioning and transfer to South Korea[edit]

In September 1947 she decommissioned and entered the Atlantic Reserve Fleet at Green Cove Springs, Florida, until 2 February 1956 when she was delivered on loan under the Military Assistance Program to the Republic of Korea at Boston Naval Shipyard. Struck from the Navy List on 1 July 1960, she continued to serve the South Korean Navy on loan as ROKS Kyongki (F-71) until she was stricken on 28 December 1977 and sent to the Philippines for cannibalization of parts.
