[7] The bow had ploughed about 22 metres (72 ft) deep into the clay seabed, at a depth of 108 metres (354 ft). This explanation is supported by reports of two underwater explosions picked up by Western agencies monitoring the area at the time, as well as by the physical evidence of the wreck when it was finally brought up from the seabed by a Dutch salvage team more than a year after the accident. [44] But the cash-strapped Russian Navy continued to use the design because the fuel is very inexpensive. The likely chain of events was something like this: A hydrogen peroxide leak started a fire, which in turn detonated the Type 65-76A’s 900-lb. At 13:30, the scheduled time period for Kursk to complete the practice torpedo firing expired without any contact from the sub. [42], Maintenance records revealed that the 65-76 "Kit" practice torpedo carried by the Kursk came from a batch of 10 manufactured in 1990, six of which were rejected due to faulty welding. Included in the technical documentation were instructions that the HTP torpedo should never be loaded into the torpedo tube more than three hours before it would be fired. The blast, located at 69°36′N 37°34′E / 69.6°N 37.567°E / 69.6; 37.567Coordinates: 69°36′N 37°34′E / 69.6°N 37.567°E / 69.6; 37.567, showed that the ship had moved about .40 kilometres (0.25 mi) after the initial explosion. [11], The second explosion was equivalent to 2-3 tons of TNT,[3] or about 5-7 combat-ready torpedo warheads. [54] The hull was suspended beneath the specially modified barge Giant 4. [20] Minister of Defence Igor Sergeyev told the American Embassy that the rescue was well underway.
[34]:108 Up to this point, family members had received 1000 rubles (about US$$37 in 2000) in compensation, and Putin offered the families additional compensation equivalent to ten years' salary, about USD$7,000 in 2000.[34]:108[37]. Thirteen Oscar I and Oscar II submarines were built, including K-141—also known as Kursk. There was considerable debate over how long the sailors survived. They found that dust and ashes inside compartment nine severely restricted visibility. The fire resulting from this explosion in turn triggered the detonation of between five and seven torpedo warheads after the submarine had struck bottom.
Employing newly developed lifting technologies, they recovered all but the bow of the vessel, including the remains of 115 sailors, which were buried in Russia. When the nuclear reactors automatically shut down, emergency power would have been limited, and the crew would have been in complete darkness and experienced falling temperatures. This included 18 SS-N-16 "Stallion" anti-ship missiles that were designed to defeat the best Western naval air defenses. [24] But this fire was separate from that caused by the exploding torpedo. [16] They reported the phenomena, but their report was ignored. [16] It surfaced and as it was being lifted onto the deck its propulsion system was seriously damaged.

Can International Cooperation Prevent Future Submarine Accidents after Russian Sub Disaster? Russian experts on one of the most technologically advanced submarines in the Russian fleet told the divers that they must open the valve counter-clockwise or they would break it.
Despite a hastily organized rescue effort, including British and Norwegian rescue teams, the Russian government was unable to reach any of the survivors in time. [16] [55] Salvage divers built two hydraulic anchors into the seabed and attached a high-strength abrasive saw that was pulled back and forth between the anchors. They reported the sounds to the Petr Velikiy.
It was the first time a Russian submarine had taken part in a NATO led exercise. Combustion, though limited in area, was fierce and took some time to extinguish. The Kursk’s sinking didn’t kill all of its 118 crewmembers—at least not right away. The first blast destroyed the torpedo room compartment and killed all seven men within. The missiles had a top speed of Mach 1.6, a range of 388 miles, and used the now defunct Legenda satellite targeting system to home in on their aircraft carrier targets. They found that the first 18 metres (59 ft) of the ship had been destroyed by the explosions.

Crew aboard the Rudnitsky tried to contact the Kursk and briefly thought they heard an acoustic SOS signal, but this was determined to be of biological origin. Their response was compared to the Soviet style of cover up and stonewalling like that during the Chernobyl disaster. Rescuers’ efforts were hampered by the icy waters, stormy weather and poor underwater visibility. [45] The Kursk's crew had no prior experience with and hadn't been trained in handling or firing HTP powered torpedoes.[17]:35. Here's the true story of the doomed sub. about 250 kilometres (160 mi) from Norway, and 80 kilometres (50 mi) from the Kola Peninsula. A navy fleet exercise became a desperate race to recover survivors hundreds of feet beneath the sea. They had no experience with HTP-powered torpedoes. Leakage of 50% peroxide onto supporting pallets under polythene sheeting led to spontaneous ignition and a fierce fire.”. It collapsed the first three compartments and all the decks, and destroyed compartments four and five, killing everyone forward of the nuclear reactor compartment.
[10]:215, The first explosion caused a fire that raised the temperature of the compartment to more than 2,700 °C (4,890 °F).

Like the exterior hull, these bulkheads were designed to withstand pressure up to 1,000 metres (3,300 ft). [4] The government refused to release a list of the missing sailors even to the families of those aboard until a Pravda reporter paid an officer 18,000 rubles for the list. The operation required planners to compensate for the effects of wave motion due to rough seas which could sever the cables suspending the sub beneath the barge. The Soviets saw American carriers as both delivery platforms capable of launching thermonuclear airstrikes against the motherland and as hunters of the USSR’s own nuclear ballistic missile fleet. The AS-34 was damaged and surfaced, so the crew of the Rudnitsky began preparing the AS-32 for operations. An investigation after most of the wreck was raised along with analysis of pieces of debris found that a crack in the casing of the practice torpedo leaked high-test peroxide that caused the kerosene fuel to explode. Norwegian Radiation Protection Authority seismic readings of the explosions on the submarine Kursk on 12 August 2000. Kursk was fully armed with Granit missiles and torpedoes and was to make a simulated attack on Kuznetsov. Gear-obsessed editors choose every product we review. When they compared the second event with the first, they concluded that first event was also the explosion of a torpedo. On Sunday, after Popov already knew that the Kursk was missing and presumed sunk, he briefed reporters on the progress of the exercise. Even then, the government tried to prohibit reporters from contacting family members. https://www.britannica.com/event/Kursk-submarine-disaster. ", While the government insisted that bad weather was making it impossible to rescue the sailors, President Putin was shown enjoying himself in casual dress on a summer holiday at a villa on the Black Sea.
The second explosion would have been the detonation of the remaining torpedoes aboard the submarine. Updates? [12] The resulting fire was later estimated to have burned at 2,700 °C (4,890 °F).
This led investigators to conclude that it was likely that the internal door was not fully closed when the explosion occurred. This second explosion was equivalent to between 2 to 3 tonnes (2.0 to 3.0 long tons; 2.2 to 3.3 short tons) of TNT. [36] He said they were trying to profit from the tragedy.
On 21 August, the Chief of staff of the Russian Northern Fleet Mikhail Motsak announced to the public that the Kursk was flooded and the crew was dead. Early in the evening, more than six hours after the explosion, Kursk failed to complete a scheduled communication check at 18:00. The danger was that this chemical compound can become explosive if it comes in contact with organic compounds or a fire. Winds increased, blowing 10–12 m/sec to 15–27 m/sec (22MPH-38MPH), and the waves rose to 3-4 points (4–8 feet), forcing the Russians to suspend rescue operations. [10]:218 No one in the command post was able to initiate an emergency ballast tank blow that might have resurfaced the submarine. The official Russian inquiry concluded that a torpedo explosion was likely the cause. A huge explosion sank the giant nuclear-powered submarine Kursk, killing most of its crew and stranding nearly two dozen survivors hundreds of feet underwater. [7] Divers had found ash and dust inside the compartment when they first opened that hatch, showing evidence of a fire.
