HMS Jaguar was a J-class destroyer of the Royal Navy.

Construction

The eight ships of the J-class were ordered on 25 March 1937, and Jaguar was laid down at the Dumbarton shipyard of Denny on 25 November 1937. She was launched on 22 November 1938 and commissioned on 12 September 1939.

Jaguar was 339 feet 6 inches (103.48 m) long between perpendiculars and 356 feet 6 inches (108.66 m) overall, with a beam of 35 feet 8 inches (10.87 m) and a draught of 9 feet (2.7 m). Displacement was 1,690 long tons (1,720 t) standard and 2,330 long tons (2,370 t) deep load. Two Admiralty three-drum boilers fed steam at 300 pounds per square inch (2,100 kPa) and 620 °F (327 °C) to Parsons to two sets of Parsons single-reduction geared-steam turbines, rated at 40,000 shaft horsepower (30,000 kW). This gave a design speed of 36 knots (67 km/h; 41 mph) at trials displacement and 32 knots (59 km/h; 37 mph) at full load.

As completed, Jaguar had a main gun armament of six 4.7 in (120 mm) QF Mark XII guns in three twin mountings, two forward and one aft. These guns could only elevate to an angle of 40 degrees, and so were of limited use in the anti-aircraft role, while the aft mount was arranged so that it could fire forwards over the ship's superstructure to maximise the forward firing firepower, but was therefore incapable of firing directly aft. A short range anti-aircraft armament of a four-barrelled 2 pounder "pom-pom" anti-aircraft mount and eight .50 in machine guns in two quadruple mounts was fitted, while torpedo armament consisted of ten 21 inches (533 mm) torpedo tubes in two quintuple mounts.

Service

On commissioning, Jaguar joined the 7th Destroyer Flotilla based at Grimsby, operating off Britain's east coast. On 11 October, the ship ran aground in the Firth of Forth and was under repair until November. In May 1940, during Operation Dynamo, Jaguar and other destroyers rescued survivors from the sinking of SS Abukir.

In February 1941 she took part in Operation Abstention in February 1941, where she engaged the Italian destroyer Crispi off Kastelorizo without consequences and the Battle of Cape Matapan next March. Jaguar was struck by two torpedoes fired by the German submarine U-652 and sank off Sidi Barrani Egypt on 26 March 1942 with the loss of 3 Officers and 190 of her crew. 8 Officers and 45 crewmen were rescued by Naval Whaler HMS Klo.
