Construction

Conn was ordered on 10 January 1942, as DE-80, a long-hulled turbo-diesel (TE) type destroyer escort, one of more than 500 such vessels built for Anti-Submarine Warfare to a collaborative British-American design.^[3] She was laid down on 2 June 1943 at the Bethlehem Hingham Shipyard, in Hingham, Massachusetts,^[4] and was transferred during construction to the Royal Navy under Lend-Lease. She was launched on 21 August 1943 as HMS Conn, and was completed three months later on 31 October 1943.^[5][6] She was named after Captain John Conn^[2] of HMS Dreadnought at the Battle of Trafalgar.

Service history

After commissioning Conn was assigned to Western Approaches Command as a convoy escort and ASW vessel. After several voyages reinforcing a depleted B7 Escort Group in early 1944 Conn was assigned to 21 EG, and in the spring of 1944 part for the escort for several coastal convoys. In June Conn and 21 EG were part of Operation Neptune, the naval component of the Normandy landings escorting convoys and patrolling for U-boats. In October Conn was part of the escort of Arctic convoy JW 61, with a new commander and as senior officer's ship of 21 EG. Her new Commanding Officer was Lt. Cdr. Raymond Hart DSC,^[2] an experienced and successful ASW officer.

In January Conn and 21 EG were operating as escort or support group to various Atlantic convoys; one of these, HX 332 came under attack, losing two ships, but despite an extensive hunt the U-boat (U-825) was not found. In March 1945 Conn and 21 EG were assigned to patrol the north-east coast of Scotland; during this period the group found and destroyed four U-boats, with Conn being credited with two of these.

After the German surrender in May 1945 Conn moved to general duties, and with the final end of the war in August 1945 was prepared for return under the Lend-Lease agreement, to the United States for eventual disposal.^[7]
