[3] She had a total length of 67.10 m (220 ft 2 in), a pressure hull length of 50.50 m (165 ft 8 in), a beam of 6.20 m (20 ft 4 in), a height of 9.60 m (31 ft 6 in), and a draught of 4.74 m (15 ft 7 in).
Futlyar is a wire-guided, combustion-driven torpedo with a top speed about 50 kn (93 km/h; 58 mph) and a maximum depth capability of more than 500 m (1,600 ft). It would be able to hit targets at a range of about 50 km (27 nmi; 31 mi). It will first equip the new Borei and Yasen classes of nuclear submarines. [1] [2] [3]
The torpedo attained a speed of 20 knots (37 km/h; 23 mph) using a wire 1.0 millimetre (0.04 in) in diameter but later this was changed to 1.8 mm (0.07 in) to increase the speed to 27 knots (50 km/h; 31 mph).

The same source suggests that the fission yield was 5·10 18 fissions (1.95mg of U-235 fissioned) which would deliver 156 MJ (37.3kg TNT equivalent) of heat into the reactor. Ten naval personnel were killed (8 officers and 2 enlisted men), probably by the explosion itself and not from radiation injuries .
