Submarine B-871 Alrosa
Project 877V / Kilo class submarine
 

Kilo class is the NATO reporting name for a type of military diesel-electric submarines that are made in Russia. The original version of these vessels is designated in Russia Project 877 "Paltus" (Turbot).

The Russian Kilo Class submarine first entered service in the early 1980s. It was designed by the Rubin Central Maritime Design Bureau, St Petersburg.

The Kilo Class (Project 877) submarine was designed for anti-submarine and anti-ship warfare in the protection of naval bases, coastal installations and sea lanes, and also for general reconnaissance and patrol missions. The Kilo is considered to be to be one of the quietest diesel submarines in the world.

The submarine consists of six watertight compartments separated by transverse bulkheads in a pressurised double-hull. This design and the submarine's good reserve buoyancy lead to increased survivability if the submarine is holed, even with one compartment and two adjacent ballast tanks flooded. The foreplanes are positioned on the upper hull in front of the fin or sail. The command and control systems and fire control systems are located in the main control room which is sealed off from the other compartments.

The submarine's propulsion system consists of two diesel generators, a main propulsion motor, a fuel-economic motor and a single shaft driving a seven-blade fixed-pitch propeller. There are two additional stand-by motors for running in shallow waters, at mooring and in cases of emergency. Two 120-cell storage batteries are installed in the first and third compartments of the submarine. The main machinery is equipped with an automatic control system.

The submarine has a launcher for eight Strela-3 or Igla surface-to-air missiles.

The submarine is equipped with six 533mm forward torpedo tubes situated in the nose of the submarine and carries 18 torpedoes with six in the torpedo tubes and twelve stored on the racks. Alternatively the torpedo tubes can deploy 24 mines. Two torpedo tubes are designed for firing remote-controlled torpedoes with a very high accuracy. The computer-controlled torpedo system is provided with a quick-loading device. The first salvo is fired within two minutes and the second within five minutes.

Submarine B-871 Alrosa laid down on 17 May 1988 at Krasnoe Sormovo Shipyard, Gorky (yard No.607), launched on 10 September 1989 , commissioned on 30 November 1990.

This submarine is equipped with a pump jet propulsion.

Now in service.
