| 05-04-1943 | Laid Down |
| 18-04-1944 | Launched |
| 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. |
By the time the Holland's and the A class submarines had come from the berths at Barrow and entered service, the Royal Navy's Submarine Service - every man a volunteer, by the way - had become accustomed to dicing with death.
This witty and perceptive account of the early years of submarine development contains much new material and the lives of the forgotten pioneers of submarines.
It includes many wonderful inventions and even more colourful inventors, but focuses primarily on John Philip Holland, the Irish-American genius who took submarine development out of the hands of lunatics and visionaries and turned it into a deadly weapon of war
