Russian nuclear submarine to be disposed of soon

ARKHANGELSK. Sept 25 (Interfax-AVN) -The Zvyozdochka shipyard in the Arkhangelsk region's town of Severodvinsk is preparing to dispose of a Murena project missile-carrying strategic nuclear submarine (DELTA-1 under NATO classification).

The shipyard's press secretary, Nadezhda Shcherbina, told Interfax that the K-447Kislovodsk submarine (factory number 311) was delivered in the second half of August.

After the spent nuclear fuel has been removed, the submarine will be taken to a dry dock to be scrapped. Documents, including on the funding of the scrapping procedures, were signed two weeks ago.

Submarines of this project belong to the second generation of underwater vessels. Russian sailors used to call them "bugs."

They were armed with the D-9 missile system that entered the Russian army's inventory on March 12, 1974. Murenas had 10 silos aboard. The first submarine of this project was laid down at the Sevmashpredpriyatiye shipyard in Severodvinsk in 1971.

The K-447 was built in 1973. It had a main power plant developing 52,000hp that consisted of two VM-4B water-cooled reactors and two OK-700 steam turbines. It was written off from the Navy in1999.

The Kislovodsk was the first Russian nuclear submarine of this type to be fitted with an autonomous digital calculating system for controlling missile armament. Its entire allowance of missiles could be launched in one burst. The D-9 system incorporated 12 R-29 (4K75, RSM-40) two-stage liquid-fuel missiles (Western designation SS-N-8) with a maximum range of 7,800km. The missile's round deviation from the target amounted to 1,500m. The missile was equipped with assets for overcoming the enemy's antimissile defense system. The warhead had a capacity of 1Mt.

The Murenas' missile systems were the first in the world to get protection from unsanctioned actions. Missile launches from these submarines were only possible if the supreme commander-in- chief issued an order to this effect. They could be effected from a depth of 55m when the submarine was moving at a speed of up to five knots and the sea swell amounted to six points.

The Murenas were organic of the 41st division that has been based in the village of Gremikha since 1974. Their combat patrolling area was mostly located between Greenland and Russia's Novaya Zemlya archipelago.

The Kislovodsk submarine had a length of 139m, width of 11.7m, average draught of 8.4m, regular water displacement of 8,900 cubic meters, full displacement of 13,700 cubic meters, operational submergence depth of 320m, full underwater speed of 26 knots, surface speed of 16 knots, crew of 120 persons, and endurance of 70 days.
