1950/1951, moderately streamlined for noise reduction, by the removal of the gun and other appendages. The bow external tubes were removed but this was widespread in the post-war fleet. It is notable the stern facing midship tubes were retained. As was the snort. The purpose of this modest conversion was the fitting of USN JT sonar. Various Submarine vs Submarine exercises and trials were carried with scientists aboard. The submarine was fully operational. Later in 1951 the submarine was taken to Chatham to be converted into a stretched high underwater speed, fully streamlined submarine.
| Length overall | 273 ft 6 inch |
| Beam | 26 ft 6 inch |
| Depth | 14 ft 3 inch |
| Displacement | 1422 tons (surface) |
| 1571 tons (submerged) | |
| Diving Depth | (i) 300 ft |
| Speed | Surface 15.25 knots (design) |
| Surface 15.25 knots (service) | |
| Submerged 9 knots (design) | |
| Submerged 8.75 knots (service) | |
| No. of shafts | 2 |
| Endurance | Surface: 7500 miles at 15.25 knots (design) |
| (ii) Surface: 8000 miles at 10 knots (service) | |
| Submerged: 80 miles at 4 knots (design) | |
| Submerged: 80 miles at 4 knots (service) | |
| Armament | 8 x 21 inch bow tubes (2 external) |
| 2 x 21 inch amidship tubes | |
| (17 torpedoes carried) | |
| 1 x 4 inch gun | |
| 1 x 20mm Oerlikon cannon | |
| 3 x 0.303 inch machine-guns | |
| Complement | (peacetime) 5 Officers and 51 Ratings |
| (wartime) 6 Officers and 56 Ratings | |
| Notes | (i) This was increased to 350 feet in the all-welded boats. |
| (ii) T Class submarines serving in the Far East were modified to carry extra fuel, which increased endurance to 11 000 miles at 10 knots. |
HMS Affray was the last RN submarine to be lost at sea. At the time of her sinking, rumours about the cause of her loss circulated widely. Many were discounted once her final resting place had been found and the Official Inquiry's report had been published. However, speculation persists to this day as to the reasons why she sank.
This is the definitive history of the Russian submarine program since WWII.
Submarines emerged as a particularly terrifying weapon after WWII, in no small part through the application of nuclear propulsion and the development of shipborne nuclear missiles. The Soviet Union invested huge funding into a world-class submarine program, producing innovative designs in imposing numbers.
Norman Polmar is a best-selling author and recognized authority on the topic. His earlier works on Russian and Soviet subs earned plaudits from high-ranking officers in both the US and Russian navies. This new volume, based on those earlier works, provides readers with the authoritative English-language history of the postwar submarine force of the USSR and Russian Federation. It includes more than 100 photographs and line drawings.|Submarines emerged as a particularly terrifying weapon after WWII, in no small part through the application of nuclear propulsion and the development of shipborne nuclear missiles.
