HMS Lowestoft was a Rothesay-class or Type 12M class anti-submarine frigate of the British Royal Navy. Lowestoft was reconstructed in the late 1960s to largely the same pattern as the third group of Leander-class frigates, with new radar and fire control and a hangar and pad for a Westland Wasp helicopter for longer range, anti-submarine, engagement. In the late 1970s it was converted as the prototype towed array frigate for the Royal Navy, but retained its full armament. Lowestoft was sunk as a target on 8 June 1986 by HMS Conqueror using a Tigerfish torpedo. She was the last Royal Naval target to be sunk still displaying her pennant number.
