The Tiger class were a class of three British warships of the 20th century and the last all-gun cruisers of the Royal Navy. Construction of three Minotaur-class cruisers (under the names Blake, Defence and Bellerophon) began during World War II but, due to post-war austerity, the Korean War and focus on the Royal Air Force over the surface fleet, the hulls remained unfinished. Against a background of changing priorities and financial constraints, approval to complete them to a modified design was given in November 1954 and the three ships – Tiger, Lion and Blake – entered service from March 1959.

In January 1964, due to postponement of the Escort Cruiser programme, the cruisers were approved for conversion into helicopter-carrying cruisers. At first they were intended to carry four Westland Wessex helicopters for amphibious operations and anti-submarine protection operating "East of Suez" then four Westland Sea Kings for anti-submarine work. The conversion of Blake and Tiger, carried out between 1965 and 1972, was more expensive and time-consuming than expected and, with the UK Treasury opposing each cruiser's conversion, the conversion of Lion was cancelled and she was scrapped in 1975, having been used for spares for her sister ships.

Described in one book as "hideous and useless hybrids" after conversion^[1] and with limited manpower, resources, and better ships available, Tiger and Blake were decommissioned in the late 1970s and placed in reserve. Blake was scrapped in 1982 and Tiger in 1986.
