HMS Lawson was a British Captain-class frigate of the Royal Navy in commission during World War II. Originally constructed as the United States Navy Evarts-class destroyer escort DE-518, she served in the Royal Navy from 1943 to 1946.

The ships had a diesel–electric powertrain derived from a submarine propulsion system with four General Motors 16-cylinder diesel engines providing power to four General Electric electric generators which sent electricity to four General Electric electric motors which drove the two propeller shafts. The destroyer escorts had enough power give them a speed of and enough fuel oil to give them a range of at. Their crew consisted of 198 officers and ratings.
The armament of the Evarts-class ships in British service consisted of three single mounts for 50-caliber /50 Mk 22 dual-purpose guns; one superfiring pair forward of the bridge and the third gun aft of the superstructure. Anti-aircraft defence was intended to consisted of a twin-gun mount for Bofors anti-aircraft (AA) guns atop the rear superstructure with nine Oerlikon AA guns located on the superstructure, but production shortages meant that that not all guns were fitted, or that additional Oerlikons replaced the Bofors guns. A Mark 10 Hedgehog anti-submarine mortar was positioned just behind the forward gun. The ships were also equipped with two depth charge rails at the stern and four "K-gun" depth charge throwers.

Construction and career

The ship was laid down by the Boston Navy Yard in Boston, Massachusetts, on 9 July 1943 as the unnamed U.S. Navy destroyer escort DE-518 and launched on 13 August 1943. The United States transferred the ship to the United Kingdom under Lend-Lease on 15 November 1943. The ship was commissioned into service in the Royal Navy as HMS Lawson on 15 November 1943 simultaneously with her transfer. She served on patrol and escort duty in the North Atlantic Ocean for the remainder of World War II, and also supported the Allied invasion of Normandy in June 1944.
After the conclusion of the war, the Royal Navy steamed Lawson to the United States, bringing her into port at the Philadelphia Naval Shipyard in Philadelphia, Pennsylvania, on 12 March 1946. The United Kingdom officially returned her to United States custody on 20 March 1946. The United States sold Lawson for scrap on 31 January 1947.
