This was a 'T' class destroyer of which nine were built between 1936 and 1937. HMS Imogen displaced 1,370 long tons (1,390 t) at standard load and 1,888 long tons (1,918 t) at deep load. The ship had an overall length of 323 feet (98.5 m), a beam of 33 feet (10.1 m) and a draught of 12 feet 5 inches (3.8 m). She was powered by Parsons geared steam turbines, driving two shafts, which developed a total of 34,000 shaft horsepower (25,000 kW) and gave a maximum speed of 36 knots (67 km/h; 41 mph). Steam for the turbines was provided by three Admiralty 3-drum water-tube boilers. HMS Imogen carried a maximum of 470 long tons (480 t) of fuel oil that gave her a range of 5,530 nautical miles (10,240 km; 6,360 mi) at 15 knots (28 km/h; 17 mph). The ship's complement was 145 officers and enlisted men in peacetime.
The ship mounted four 45-calibre 4.7-inch Mk IX guns in single mounts. For anti-aircraft (AA) defence, Imogen had two quadruple Mark I mounts for the 0.5 inch Vickers Mk III machine gun. She was fitted with two above-water quintuple torpedo tube mounts for 21-inch (533 mm) torpedoes. One depth charge rail and two throwers were fitted; 30 depth charges were originally carried, but this increased to 35 shortly after the war began.
The ship was ordered on 30 October 1935 from Hawthorn Leslie at Hebburn under the 1935 Naval Programme. She was laid down on 18 January 1936, launched on 30 December 1936, as the seventh Royal Navy ship to carry this name, and completed on 2 June 1937, at a contract price of £256,917, excluding items supplied by Admiralty such as armaments and communications equipment. HMS Imogen was assigned to the 3rd Destroyer Flotilla of the Mediterranean Fleet upon commissioning and was initially based in Malta. Transferred to Gibraltar, she patrolled Spanish waters enforcing the policies of the Non-Intervention Committee during 1938. The ship was given a brief refit in Malta from 17 October–28 November 1938 and another at Sheerness Dockyard in August 1939.
Imogen returned to the Mediterranean on 3 September, but was transferred to the Western Approaches Command for convoy escort duties two days later when Italy did not enter the war. Together with the entire 3rd Destroyer Flotilla, the ship was transferred to the Home Fleet in October. Together with her sister Ilex, she sank the German submarine U-42 on 13 October after the submarine attempted to sink the freighter SS Stonepool. Whilst escorting the merchant ship to Barry, Imogen rescued survivors from the ships Louisiane and Bretagne. She was refitted at Liverpool between 20 October and 7 November and then rejoined Home Fleet. The following month, the ship came to the aid of the torpedoed battleship HMS Barham off the Butt of Lewis on 28 December.
With her sister Inglefield and the destroyer Escort, Imogen sank U-63 after it had been spotted by the British submarine Rorqual on 25 February 1940. During the Norwegian Campaign, the ship searched unsuccessfully for German ships, escorted ships of Home Fleet and troopships carrying Norwegian Army units from Kirkenes and Alta to Sjøvegan in mid-April.
In mid-June, she escorted the aircraft carrier HMS Illustrious to Bermuda to work up. Off Duncansby Head during the night of 16 July, Imogen collided with the light cruiser HMS Glasgow in thick fog whilst bound for Scapa Flow. She was badly damaged and caught fire. HMS Glasgow rescued 10 officers and 125 enlisted men. The stern section was carried west by the ebb tide until it sank about 4 miles to the west-north-west of Stroma light at position 58 34 13N, 02 56 09W. She had fired distress signals repeatedly by gun and rocket and aid was summoned by the Stroma coastguards but owing to fog and strong tides she was not located in time to save the crew. Seventeen men who were still on board were killed and one other died later from his injuries. One officer and eight ratings were injured. She was commanded by Cdr. C.L. Firth, M.V.O.
The wreck of the HMS Imogen is believed to lie in a least depth of 73m, in orientation 165/345 degrees.
