One of the explosions ripped a large gash in her forward bow, near the torpedo compartment. The two attempts on Tuesday to reach the Kursk were frustrated by of poor underwater visibility and 12-foot high waves. As of Friday it was officially estimated it could last another five days. The Norwegian Stolt Offshore company received blueprints representatives of the naval design center which designed the sunken submarine that showed where deep water frogmen may enter the boat. script.setAttribute("async", true); A bleak reality of submarine operations is that if a submarine goes missing in an area where the depth of water is greater than its crush depth, there is little hope for the crew’s survival. Kursk went up to the periscope depth of 19 meters to find the ‘opponent’ ships, which were to enter the area, at around 11:00. K-129.

This suggests that, starting with 0.21 atm of oxygen, the oxygen partial pressure will still be 0.15 atm even when 0.06 atm of carbon dioxide is present. It would take several months only to build such a device. Likely no one will ever know for sure what caused the disaster. Radiation Hell: Russia Has Had Horrific Submarine Disasters The Soviet and later Russian Navy have unfortunately seen more than their fair share of modern submarine disasters.

The third version, the Vice-premier believed, could be an emergency situation in the submarine's torpedo compartment.
