...turbine and machinery spaces behind the reactors. The flash flooding in the forward part of the Kursk would have caused the bow to drop, pitching the 14,000-ton boat into a steep dive with steam turbines still delivering power to its twin screws. In seconds, the sub would have pounded into the seabed some 350 ft. beneath the storm-driven surface of the Barents Sea with a shock that would have hurled survivors against equipment and bulkheads. Finally, as the boat settled onto the ocean floor, openings along the keel would probably no longer have been able to draw...
...more or less." The tapping out of SOS signals in Morse code indicated that some crew members survived for a time in the stern sections of the boat, but Admiral Vyacheslav Popov, commander of the Northern Fleet, admitted on Friday evening that no tapping had been heard from the sub since Aug. 14, two days after the accident...
...disaster. They made no announcement for two days, then issued a bland statement that there had been a "technical fault" and the boat was on the sea bottom. After the seriousness of the accident became clearer, Defense Minister Igor Sergeyev declared that there was "incontrovertible evidence" that the sub had collided with another vessel. In past years Soviet and U.S. vessels have had near collisions while spying on each other, but the Pentagon firmly rejected any suggestion that U.S. submarines were involved. Later, Russian officials dropped the collision claim and blamed an explosion in the weapons area, a theory supported...
Klebanov never truly let go of the collision theory, saying the sub hit a "huge, heavy object" of "very large tonnage" that tore open the boat's hull. But he offered no suggestions about what that might have been, and there were no reports of a surface ship in the area with severe hull damage...
...sub hasn't been lost for more than 30 years because of a rigorous certification program that gives each key piece of a submarine--including its hull, pipes, valves and flood barriers--a serial number pinpointing its source and whom to hold accountable if it fails. Critical systems are duplicated. For example, there are three ways to empty the ballast tanks on Trident missile boats. U.S. submarine crews are repeatedly drilled, ashore and afloat, with two key aims: to keep their sub safe and, if that fails, to get out alive. The top concerns for crews include knowing...
