Reference News Network reported on January 8 The British Sun News website published a report on the top secret plan on December 30, 2018: The Soviet Union used German technology to develop a report on a giant submarine capable of carrying tanks to join the battle.
The report quoted a top-secret plan during the Cold War period when Soviet engineers developed a giant submarine that could transport tanks to fight. The ultimate war machine, called P2, is 10 times the size of a submarine of the same type, with the aim of changing the face of underwater combat.
It is reported that this giant submarine designed in 1949 and built with German technology will become the pride of the Soviet Navy once it is in service.
Submarine expert H.I. Sutton said that P2 was the most advanced submarine in the world at the time. He said: From the design point of view, the submarine is huge in size, with three separate torpedo compartments (two in the boat and one in the stern) with a total of 16 torpedo tubes. At that time, the US Navy submarines were equipped with up to 10 launch tubes, and the nuclear-powered attack submarines that later became the main force were reduced to four.
The report said that the P2 submarine is equipped with two anti-aircraft guns with calibers of 57 mm and 25 mm, respectively, to withstand enemy anti-submarine aircraft. It also has a cruise missile launcher, but its secret weapon is the 9 small submarines, each capable of carrying an amphibious landing with a main battle tank.
Sutton told the reporter of the Volkswagen Machinery Monthly that P2 was the pinnacle of the ambitious (plan) of the Soviet Navy during Stalin. It combines the latest submarine design knowledge from World War II with the latest cruise missile technology. He said that until the Soviet Union mastered the relevant technologies of Nazi Germany at the end of World War II, they had the opportunity to obtain advanced cruise missile design and manufacturing methods.
Sutton said that at the time of the Cold War "both sides of the Iron Curtain, both sides had seriously considered designing the transport submarine and using it to carry out amphibious operations, but (like P2) combined the amphibious transport capability and the missile strike capability. The submarine is still puzzling.
For whatever reason, the submarine was not actually built, and the Soviet Union chose a more practical ballistic missile submarine.
