Renamed Talent in 1945.
| 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. |
K13 was carrying out her final acceptance trials prior to the Admiralty officially taking her over from her Clydeside builders. She had already covered the measured mile at a record 23 knots to gain the honour of the world's fastest submarine and there was a festive air about the pre-diving lunch which continued to 3:15 pm. And as she glided slowly down to the diving area in Gareloch she was carrying not only her regular crew of 53 officers and men but also 14 directors and employees of Fairfield, 13 other civilians, and two Royal Navy submarine officers acting as observers. When she arrived at the loch she picked up two more civilian experts. She dived smoothly enough but to Lt-Cdr Herbert's consternation she refused to trim level at 20 feet and continued plunging toward the bottom.
This book tells the exhilarating story of the will, endurance, and technical know-how of extraordinary people who made a lifelong impact on an entire nation and sixty-nine grieving families, recounting the search, discovery and the resulting attempts to find out what really happened that night, over thirty years previous. The story of the lost submarine captured the public's heart. Many Israeli cities and towns have a Dakar Street, and several schools and other public institutions are also named for the lost submarine.
Full Circle, a television documentary of the project was first aired on the National Geographic Channel in November 2003, adding to public recognition of this event.
