The Type 41 or Leopard class were a class of anti-aircraft defence frigates built for the Royal Navy (4 ships) and Indian Navy (3 ships) in the 1950s. These ships were designed to provide anti-aircraft escorts to convoys, as a result they were not built for fleet speeds and made only 24 knots (44 km/h). They shared a common hull and machinery with the Type 61 or Salisbury class aircraft direction vessels. An intended anti-submarine version, the Type 11 class (see Type system of the Royal Navy), was cancelled due to the low top speed being insufficient to combat contemporary adversaries, and was replaced by the turbine powered Type 12. HMS Jaguar and HMS Lynx were sold to the Bangladesh Navy in 1978 and 1982 respectively, and were still in service in 2007.
