HMS Cubitt (K512)

HMS Cubitt (K512) was a Captain-class frigate of the British Royal Navy that served during World War II. The ship was laid down as a Buckley-class destroyer escort at the Bethlehem-Hingham Shipyard at Hingham, Massachusetts on 9 June 1943, with the hull number DE-83, and launched on 11 September 1943. The ship was transferred to the UK under Lend-Lease on 17 November 1943, and named after Captain J. Cubitt, a Navy officer who commanded the frigate HMS Mary Rose (1654) in 1661.

Service history
Cubitt was assigned to Nore Command, serving in the 21st Escort Group based at Harwich. She did not take part in the Normandy landings on 6 June 1944, but was afterwards deployed escorting convoys to and from the landing beaches. Towards the end of 1944 Cubitt became a Coastal Forces Control Frigate (CFCF), controlling a flotilla of Motor Torpedo Boats operating in the Channel and North Sea to counter the threat of enemy E-Boats.

In February 1945 Cubitt was refitted at Tilbury. Her 2-pounder "pom pom" bow chaser was removed, the two 20 mm Oerlikons mounted in front of the bridge were replaced with two single 40 mm Bofors, and splinter shields were fitted to her 3 in guns.

On the night of 7/8 April 1945 Cubitt and HMS Rutherford (K558) were on patrol with their MTB's when Cubitt encountered a large group of E-Boats. She opened fire, and two were severely damaged and a third was hit before they could move out of range, but a patrolling aircraft then attacked and drove them towards the MTB's, resulting in a fierce close-quarter action. A Motor Gun Boat and an E-Boat collided, and Cubitt picked up casualties from another MGB that was on fire. The following night Rutherford and Cubitt were on patrol off Ostend, when an aircraft directed Rutherford towards a formation of E-Boats, and in five minutes two E-boats were sunk and several others damaged. Cubitt managed to fire a few shots as the E-boats fled under cover of a smoke screen.

Cubitt visited several Dutch ports immediately after they were liberated, and after VE Day escorted ships to Oslo and Brunsbüttel. Cubitt was then assigned to "Operation Deadlight", towing surrendered U-boats from Loch Ryan out into the North Atlantic where they were sunk.

Cubitt was returned to the U.S. Navy on 4 March 1946, struck from the Navy List on 12 April 1946, and sold for scrapping on 7 March 1947.
