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. The Type 41, together with the Type 61 variant introduced diesel propulsion into the Royal Navy, the perceived benefits being long range, low fuel use, reduced crew (especially skilled artificers), and reduced complexity.

Although successful, improvements in traditional steam turbine technology erased the fuel economy advantage of the diesel powerplants and led to production being curtailed in favour of the Type 12 frigate, which was similar in overall design.

HMS Lynx (F27), was a Leopard-class Type 41 anti aircraft frigate of the Royal Navy, named after the lynx.

She was laid down by John Brown & Company, Clydebank,[Scotland, on 13 August 1953, launched on 12 January 1955, and commissioned on 14 March 1957. On 12 March 1982 she was sold to the Bangladesh Navy and renamed BNS Abu Bakr. She was decommissioned and scrapped in 2014.
