HMS Andrew (P423), was an Amphion-class submarine of the Royal Navy, built by Vickers Armstrong and launched on 6 April 1946.

The submarine was fitted with a 4 inch deck gun in 1964 for service during the Indonesia–Malaysia confrontation to counter blockade running junks.[1] The gun was fired for the last time in December 1974.[2] She was sold off in 1977 and was broken up.

HMS Andrew made several claims to submarine history:

  • she was the oldest submarine of the Amphion class in service
  • she was the last UK submarine to carry a deck gun
  • she was the last submarine designed during the Second World War remaining in service
  • she was the first submarine to cross the Atlantic submerged using the "snort", in May 1953.[3] The 2,500-nautical-mile (4,600 km), 15 day trip from Bermuda to England set a new world record for continuous underwater operation.[3]

Film career[edit]

HMS Andrew was used in the 1959 film On the Beach to depict the fictional United States Navy nuclear submarine USS Sawfish because the U.S. Navy did not cooperate in the production of the film.
