HMS Aeneas (P427)

Birkenhead-Built

HMS Aeneas was built by Cammell Laird at Birkenhead, laid down on 28 April 1944, launched on 5 October 1945 and commissioned on 31 July 1946, an Amphion-class submarine developed from the wartime T-class design, displacing 1,385 tons on the surface and armed with ten 21-inch torpedo tubes alongside a 4-inch deck gun, three machine guns and an Oerlikon 20mm cannon.

Training a Future Admiral of the Fleet

In 1950, Aeneas was visited by nuclear submarine engineers from the Harwell Laboratory, an early sign of the direction the Submarine Service was heading, and between 1951 and 1952 she carried a young officer named John Fieldhouse, who would go on to become Admiral of the Fleet and command British forces during the Falklands War.

She took part in the Coronation Review of the Fleet for Queen Elizabeth II in 1953, a proud moment for any warship of the era.

A Star Turn in You Only Live Twice

Aeneas achieved a rather different kind of fame in 1967, playing the part of the fictional submarine M1 in the James Bond film You Only Live Twice, a fun bit of Cold War-era cinema trivia for a boat that spent most of her career in far less glamorous, entirely serious naval work.

Testing Anti-Helicopter Missiles

In 1972, Aeneas was loaned to Vickers to support trials of the Submarine-Launched Airflight Missile, or SLAM, an experimental system intended to let a submerged submarine engage helicopters and low-flying aircraft, a particularly inventive if ultimately niche piece of Cold War weapons development.

The End of the Line

HMS Aeneas was placed on the disposal list by the UK government in 1973 and sold on 14 November 1974, before being scrapped at Dunston on Tyne, bringing to a close the career of a submarine whose service ranged from training future admirals to a memorable supporting role on the silver screen.
