According to Joinfo.ua with reference to Rzeczpospolita, the construction of submarines is carried out in the shipyard Sevmash located in Severodvinsk.
Each submarine is capable of carrying on board 20 Bulava ballistic missiles, aimed at transportation of nuclear warheads to the distance of 8000 kilometers. The submarines will be called "Knyaz Vladimir", "Knyaz Oleg", "Kazan" and "Generalissimo Suvorov".
These four submarines will be built in the coming years. And by the year of 2020, the Russian Federation intends to lay the foundations of nuclear forces in the Arctic region, erecting eight nuclear submarines.
Previously, it was reported that the United States developed a secret aircraft TR-3B Astra.
American TR-3B Astra is the secret development of tactical reconnaissance aircraft. Most often witnesses of this aircraft consider it a triangular-shaped UFO due to the fact that the power plant of the aircraft is a generator of the powerful magnetic vortex field and people see the luminous flux emitted periodically by this generator as unearthly and inhuman. Thiscreates an opportunity to move around easily and maneuverably in the air and to surpass all the aircraft by specifications.
