The Remains of Kursk Submarine
‘The Kursk sailed out to sea to perform an exercise of firing dummy torpedoes at Pyotr Velikiy, a Kirov class battlecruiser. On August 12, 2000 at 11:28 local time (07:28 UTC), the missiles were fired, but an explosion occurred soon after on Kursk. The only credible report to-date is that this was due to the failure and explosion of one of Kursk’s new/developmental torpedoes. The chemical explosion blasted with the force of 100-250 kg of TNT and registered 2.2 on the Richter scale [1]. The submarine sank to a depth of 108 metres, approximately 135km (85 miles) off Severomorsk, at 69°40′N, 37°35′E. A second explosion 135 seconds after the initial event measured between 3.5 and 4.4 on the Richter scale, equivalent to 3-7 tons of TNT [2]. Either this explosion or the earlier one propelled large pieces of debris far back through the submarine.’
