Submarine B-871 ("Alrosa")
Project 877V / Kilo class submarine
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. These missiles are manufactured by the Fakel Design Bureau, Kaliningrad. Strela- 3 (NATO Designation SA-N-8 Gremlin) has a cooled infrared seeker and 2kg warhead. Maximum range is 6km. Igla (NATO designation SA-N-10 Gimlet) is also infrared-guided but heavier, with a maximum range of 5km and speed of Mach 1.65.
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" was built by "Krasnoe Sormovo", Gorky, commissioned on 1990.
From 1990 submarine has name "B-871", in Jan 2003 was renamed to "Alrosa".
This submarine is equipped with a pump jet propulsion.
