Post war modification

Several major changes were made to the Amphion-class submarines after entering service including fitting a ‘snort mast’ (based on the German schnorkel), a night periscope and two radar masts were added. Each radar mast had a rotating antenna, one for aircraft warning and the other for surface warning, which could be used from periscope depth. Additional equipment which improved plotting and fire control arrangements resulted in a rearrangement of the entire control room. More modifications sere done in the 1950s when the upper decks and conning tower was ‘streamlined’ by removing all external torpedo tubes and fuel tanks. Her 4 inch, and other gun mounts were removed and her conning tower modified.

Modernisation refit

Many of the remaining Amphion-class vessels underwent a more radical modification refit and modernisation in the early 1960s which resulted in a radical change in appearance; they now resembled the silhouette of the Porpoise class Diesel Electric boats that were entering service in the late 1950s. In 1967 AENEAS played the part of the M1 submarine James Bond film ‘You Only Live Twice the same year saw the first of the class withdrawn from service for scrapping.

HMS AENEAS was hired by Vickers in 1972 for successful trials of SLAM (Submarine Launched Anti-Aircraft Missile), a system using a cluster of four Shorts Blowpipe missiles on an extendable mast, allowing attacks against low flying aircraft while the submarine was at periscope depth. She scrapped in 1974; the last operational Amphion-class boat, ANDREW, was decommissioned in 1974.

The only surviving example of the Amphion-class submarine, HMS ALLIANCE, has been preserved at the Royal Navy Submarine Museum, Gosport, Hampshire, and is open to the public.

LCdr Richard Sharpe relieved LCdr Greig in 1966. He was relieved in late 1967 or early 1968. I can't remember the name of his replacement. I was the executive officer (1965-1968) for all three of these commanding officers.
