The Russian authorities say an explosion on a Russian submarine , within Russian territorial waters has killed 14 sailors.
The submarine is identified as AS-12 (nicknamed LOSHARIK). President Putin said seven of the 14 were captains and that two of the dead had received high military honors.
Russian authorities did not say how many people were aboard the vessel at the time of the fire. The Ministry of Defense said the vessel was returned to the base at Severomorsk.
The authorities refused to say if the vessel was powered by a nuclear reactor or whether it was submerged at the time of the accident.
On Tuesday evening, an official with the Radiation and Nuclear Safety Authority in Norway said the agency had taken radiation measurements after the incident but detected nothing unusual, Reutersreported.
Although the Ministry of Defense described the stricken vessel as a “scientific experimental deep water apparatus intended to study the natural environment and sea floor” other sources describe it as a nuclear-powered submarine used to spy.
The accident aboard the Kursk in 2000 had proved a difficult moment for Mr. Putin.
The Kursk, sank after a torpedo exploded during a test launch. The Russian military, threadbare after the Soviet collapse, lacked rescue equipment and waited days before appealing for international help.
Vladimir Putin was outspoken about this secret submarine and especially about the crew, most of whom were officers. “It is not an ordinary vessel, as we know. It is a scientific-research vessel, its crew is highly professional.” The officers who died included First rank captain Denis Dolonsky, the commander of the Losharik. Dolonsky received the Hero of Russia for “Arctic and Antarctic research works”. Nikolay Filin, another captain and recipient of the Hero of Russia award, was a tester of deep sea military equipment.
A third captain was Andrey Voskresensky, the son-in-law of Russian rear admiral Vladimir Bederdinov. In all seven first rank sea captain were killed on board the submarine while deployed on an unknown secret mission.
