The Royal Navy's all nuclear-powered submarine force arrived just a few years after it accepted for service four modern diesel-electric submarines of the UPHOLDER (S40) class (designated SSK for hunter killer). The decision to retire these excellent boats was made for financial reasons following the Cold War. This note reviews the Upholders and their retirement from the fleet.
The story of HM Submarine Upholder, ordered just days before the Second World War started.
Serving with the 10th Submarine Flotilla, she was commanded by David Wanklyn VC. One of the most successful British submarines of World War Two, sinking two destroyers, three submarines, three transports, ten merchant ships, two tankers and one trawler, totalling 128,353 tons of shipping.
Upholder sailed out of Grand Harbour, Valetta, in Malta in April 1942, never to be seen again, and is believed sunk off the Lybian coast, near Tripoli.
