HMS Redoubt was an R-class destroyer built for the Royal Navy during the Second World War.

Redoubt displaced 1,705 long tons (1,732 t) at standard load and 2,425 long tons (2,464 t) at deep load. She had an overall length of 358 feet 3 inches (109.2 m), a beam of 33 feet 8 inches (10.3 m) and a deep draught of 13 feet 6 inches (4.1 m). She was powered by two Parsons geared steam turbines, each driving one propeller shaft, using steam provided by two Admiralty three-drum boilers. The turbines developed a total of 40,000 shaft horsepower (30,000 kW) and gave a maximum speed of 36 knots (67 km/h; 41 mph). Redoubt carried a maximum of 470 long tons (480 t) of fuel oil that gave her a range of 4,675 nautical miles (8,658 km; 5,380 mi) at 20 knots (37 km/h; 23 mph). Her complement was 176 officers and ratings.^[1]

The ship was armed with four 45-calibre 4.7-inch (120 mm) Mark IX guns in single mounts. For anti-aircraft (AA) defence, Redoubt had one quadruple mount for QF 2-pdr Mark VIII ("pom-pom") guns and six single 20-millimetre (0.8 in) Oerlikon autocannon. She was fitted with two above-water quadruple mounts for 21-inch (533 mm) torpedoes. Two depth charge rails and four throwers were fitted for which 70 depth charges were provided.^[2]

HMS Redoubt was built by Clydebank and launched in 1942.

Between 1946 and 1947 Redoubt was part of the reserve held at Chatham Dockyard, being transferred to the Harwich reserve in August 1947. Between 1948 and 1949 she underwent a refit at Chatham Dockyard. She was transferred to India 4 July 1949, where she was commissioned as INS Ranjit and allocated the pennant number D209.^[3]

In 1953 she took part in the Fleet Review to celebrate the Coronation of Queen Elizabeth II^[4] Along with two other former R-class destroyers (Rajput and Rana) she formed part of the 11th destroyer Squadron.^[5] She served until 1979, and was scrapped after decommissioning.^[6]
