| 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. |
Prior to the Allied landings in Italy in September, HMS/M Severn had been involved in cloak & dagger operations such as the landing of commandoes on the island of Sardinia where they were to destroy the torpedo bomber base at Cagliari (but that's another story). The year was 1943 and the events recounted herein occurred towards the end of that year, following the unconditional surrender of the Italians in September.
Charts over a century of submarine development, from the earliest attempts to travel beneath the waves, two World Wars and the Cold War, through to the formidable machines in operation today.
Specification boxes provide at-a-glance information about each submarine's country of origin, length, displacement, speed, armament, propulsion and complement. Features more than 700 historical and modern photographs illustrating each type of submarine, plus artworks of selected examples. Includes fascinating quotes from military leaders and a glossary explaining key naval terms and abbreviations.
