| Beam | 15 ft 9 inch |
| Depth | 15 ft 9 inch |
| Displacement | 630 tons (surface) |
| 730 tons (submerged) | |
| Diving Depth | 200 ft |
| Speed | 11.5 knots (surface) |
| 9 knots (submerged) | |
| No. of shafts | 2 |
| Endurance | Surface: 4050 miles at 10 knots (design) |
| Submerged: 23 miles at 8 knots or 170 miles at 2.5 knots (design) | |
| Armament | (i) 4 x 21 inch bow tubes (8 torpedoes carried) |

| (ii) Undine and Unity, which were not fitted with the 3 inch gun, had 27-man complements. |
The last of four Chinese Yuan diesel electric submarine has appeared. There was no official information released, but based on photos available it appears to be another development in China's taking Russian submarine technology and adapting it for Chinese designs.
The 2000 K-141 Kursk submarine disaster is followed by governmental negligence. As the sailors fight for survival, their families desperately battle political obstacles and impossible odds to save them.
