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.
