...his unusual arrangement is explained by the dimensions of the submarine developed by NII-400 under the leadership of N. Shamarina. The length of the torpedo was about 23 meters, weight torpedo - 40 tonnes, the weight of the warhead - 3,5-4 thousand. Kg. The main burden falls on the battery that ensures the dash speed of 29 knots, while the cruising range of 30 kilometers. Presumably torpedo T-15 was proposed to use a thermonuclear charge. Torpedo warhead was developed in the KB-11 Minsredmash Soviet Union, under the leadership of Chariton JB Undermining thermonuclear charge was produced shock or remote (hour) fuse. Management firing torpedoes T-15 was provided with torpedo fire control station "Tantalum".
The "nuclear supertorpedo" T-15 later was raised again, and in this context that the great complexity of life comes by itself. It was A.D.Saharov, who after a successful test 30 October 1961 his powerful 58 Mt bomb, thought about the delivery of such charges. It was clear that bulky and awkward "beast" ("superbomba" was 8 m and 2 m in diameter and 27 tonnes) were neither aircraft (in real combat sorties) nor the missile (at least none of those then existing). And that's when Sakharov decided that the delivery system can be a large torpedo. To attack from a distance of several hundred kilometers should become the enemy's ports. Of course, the destruction of the ports with 100 megaton charge and underwater explosion will produce very large loss of life.

Could they have made supertorpedoes to attack port cities based on the T-15? One of the first people with whom Sakharov spoke about the project was the counter agent and Admiral Fomin. He was shocked by the project's potential of taking so many civilian lives. Sakharov realized the navy was used to openly fighting armed opponents and the idea of such mass killings was revolting. Sakharov never discussed the project with anyone else again. Read his diaries. Life isn‘t easy...

Rubin, a submarine design bureau in St Petersburg. It would, apparently, be launched by nuclear-powered submarines of the 09852 "Belgorod" and 09851 "Khabarovsk" series. Rossiiskaya Gazeta called the torpedo a "robotic mini-submarine", travelling at 100 knots (185km/h; 115mph), which would "avoid all acoustic tracking devices and other traps" [the combitioan of speed and range claimed for this system is implausible].
