Design.
"Limbourne" was one of seven Type III Hunt-class destroyers ordered for the Royal Navy on 4 July 1940, as part of the 1940 War Emergency Programme. The Hunt class was meant to fill the Royal Navy's need for a large number of small destroyer-type vessels capable of both convoy escort and operations with the fleet. The Type III Hunts differed from the previous Type II ships in replacing a twin 4-inch gun mount by two torpedo tubes to improve their ability to operate as destroyers.
The Type III Hunts were long between perpendiculars and overall, with a beam was and draught . Displacement was standard and under full load. Two Admiralty boilers raising steam at and fed Parsons single-reduction geared steam turbines that drove two propeller shafts, generating at 380 rpm. This gave a design maximum speed of . of oil fuel were carried, giving a range of at .
Main gun armament was four 4 inch (102 mm) QF Mk XVI dual purpose (anti-ship and anti-aircraft) guns in two twin mounts, with a quadruple 2-pounder "pom-pom" and three Oerlikon 20 mm cannon providing close-in anti-aircraft fire. Two torpedo tubes were fitted in a single twin mount, while two depth charge chutes, four depth charge throwers and 70 depth charges 
comprised the ship's anti-submarine armament. Type 291 and Type 285 radars were fitted, as was Type 128 sonar.
Construction and service.
"Limbourne" was laid down at Alexander Stephen and Sons' shipyard at Linthouse, Glasgow on 8 April 1941. She was launched on 12 May 1942, and was completed on 24 October 1942.
After commissioning, "Limbourne" spent November in sea trials and work up with the Home Fleet at Scapa Flow, interrupting work up to escort the battleship out to Gibraltar and the aircraft carrier and battleship back to the UK from the Mediterranean Sea following the Anglo-American landings in North Africa. After completing workup, she joined the 15th Destroyer Flotilla based at Devonport.
In January and February 1943 "Limbourne" escorted convoys between the UK and Gibraltar, while in March, the ship was under repair at Portsmouth, with a propeller being replaced. Following the completion of these repairs, "Limbourne" was deployed on escort and anti-submarine patrol duties in the Western Approaches and the Bay of Biscay, together with operations against German convoys in the English Channel. On the night of 3/4 October 1943, "Limbourne", together with , and the destroyers and , was on patrol off the coast of Brittany when they encountered five German torpedo boats (, , , and ).
