K – 141 "Kursk" – the Soviet/Rusian nuclear submarine

K-141 "Kursk" (Russian К-141 "Курск") is a submarine of the Russian Navy's, which sank in 2000. August 12 The ship sank in the Barents Sea at 11:20 p.m. local time by participating in military exercises. All 118 sailors on board were killed. Two major explosions sank a gigant nuclear-powered submarine, the “Kursk”, killing most of its crew and imprisoning the survivors and sinking deep underwater. At the time, the Russian navy did not have the technical capacity to rescue the surviving crew, and the international rescue team was unable to reach the sailors in time. The K-141 “Kursk” was an “Oscar II”-class submarine, designed to destroy large ships, mostly aircraft carriers. The “Oscar II”-class submarines were 155 meters long and 18 meters wide at their widest point. Its water capacity is 19,400 tons. The ship was powered by two OK-650 nuclear reactors, which together produced 97,990 h. p.. Such power enabled the ship to develop a speed of 33 knots underwater. Each “Oscar II”-class submarine carried 24 P-700 “Granit” missiles, each a small 10-meter-long aircraft weighing 6,985 kilograms. The maximum rocket speed was 548.8 meters per second and the range was 624 kilometers. The “Legend” satellite tracking system, which is no longer operational, was used to target their aircraft carriers. The P-700 “Granit” missile had 749.7 kilograms of explosive heads, which was enough to destroy the aircraft carrier, or 500 kiloton heads, which were also enough to destroy the aircraft carrier in one shot. On August 12, 2000, “Kursk” participated in a major military exercise with the air carrier “Admiral Kuznetsov” and the cruiser “Peter the Great”. “Kursk” was armed with P-700 “Granit” missiles and torpedoes to simulate an attack by “Admiral Kuznetsov”. At 11:20 a.m. local time, the exercise site was shaken by an underwater explosion, followed by an even larger explosion a few minutes later. The Norwegian seismic observation station recorded both explosions. Affected by the explosions, the “Kursk” sank at a depth of 108 meters at a vertical angle of 20 degrees. One of the explosions ripped through a notch in the front hull near the torpedo compartment. The Russian Navy's inquiry council later found an explosion in one of the submarine's 65-76A heavy-duty torpedoes, resulting in an incision. The explosion was caused by improper welding, which prevented the hydrogen peroxide fuel chamber from surviving. A leak of hydrogen peroxide sparked a fire, that then detonated a type 65-76A explosive head. This led to a notch in the hull above the torpedo compartment. The second explosion is detonation the remaining submarine torpedoes. According to skeptics, the sailors, imprisoned on board, could have been rescued, if the international rescue team had been allowed to come and start work in time. But Russian President Vladimir Putin told a news conference a few days after the tragedy, that no Russian or foreign rescuers were technically able to reach the people on the submarine in time. Experts refuted this assessment. They said it was likely, that the submarine would be opened in time and some of the survivors rescued after the Western aid proposals were accepted.

A huge, well-designed and richly detailed model, the main complexity of which is size. And anyway, like all modern nuclear submarine models, it's another a big "cigar." In the model it is possible to make an openable rocket shaft with rockets inside, all protruding details of the control superstructure. However, without giving it all up, this model will be assembled best even for an advanced beginner, working under the supervision of a more experienced colleague. The publication consists of a 1 mm thick additional cardboard sheet.
