Work on further units of the Valiant Class was suspended as emphasis switched to the production of Resolution Class ballistic missile submarines. However as the polaris project neared completion, three new nuclear powered submarines were laid down - Churchill and Courageous at Vickers and Conqueror at Cammal Laird.

Appropriately Churchill is one of the few warships to have been named during the lifetime of her namesake. As First Lord of the Admiralty, Winston Churchill had insisted that submarines be named rather than numbered, as a mark of respect to those who last their lives in the silent service. Churchill had the distinction of being the last nuclear submarine to be refitted at Chatham Dockyard. She decommissioned on February 28th 1991 and is laid up at Rosyth.

Courageous served in the Falklands Conflict under the command of Rupert Best. She was the first RN sub fitted with sub-harpoon. She paid off on April 10th 1992.

Conqueror was the only fleet submarine to be built by a company other than Vickers and was one the most distinguished warships of recent years, being the only nuclear submarine to sink enemy warship, and the first to fire in anger. Under the command of Christopher Wreford-Brown (who was later awarded the DSO) Conqueror spotted the Argentine Cruiser General Belgrano. The war cabinet approved the sinking and on May 2nd 1982 Conqueror fired three torpedoes (Mk 8 torpedoes, rather than the less reliable but newer Mk 24 Tigerfish) two of which hit the Belgrano, and the third reportedly hit her escorting destroyer Hippolite Bouchard without effect. Bouchard and her sistership Piedra Bueno attempted to depth charge Conqueror as she withdrew. 321 members of Belgrano’s crew were lost, making her destruction the biggest loss of the war. During the conflict Belgrano carried out a 90 day patrol, the longest ever by a Royal Navy submarine. Conqueror was fitted with sub-harpoon in 1985. She collided with a yacht in July 1988 off the Mull of Kintyre. Paid off together with Warspite in a joint ceremony at Devonport in 2 August 1990. After decommissioning her reactor core was removed, her hatches sealed and her inside gutted.
