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). There is also a more advanced version, which is designated in the west Improved Kilo and in Russia as Project 636 Varshavyanka. The Kilo will be succeeded by the Lada class submarine, which began sea trials in 2005.
The boats are mainly intended for anti-shipping and anti-submarine operations in relatively shallow waters. Kilo class submarines can operate very quietly. Project 636, sometimes called by the US Navy "The Black Hole" for its uncanny ability to "disappear", is thought to be one of the quietest diesel-electric submarine classes in the world. [1]
Anechoic tiles are fitted on casings and fins to absorb the sonar sound waves of active sonar, which results in a reduction and distortion of the return signal. These tiles also help attenuate sounds that are emitted from the submarine, thus reducing the range by which the sub may be detected by passive sonar.[1]

[edit] Operators
The first submarine entered service in the Soviet Navy in 1982, and submarines of these types are still in use with the Russian navy. By November 2006, 16 vessels were believed to be in active service and 8 vessels were thought to be in reserve [2]. Another 29 vessels have been exported to various countries:
- Algeria (2 Kilo; Rajs Hadi Mubarek and El Hadi Slimane, operational since 1987, refitted in 1990)
- People's Republic of China (2 Kilo, 2 Improved Kilo, and 8 further Improved Kilo)
- India (10 Kilo designated the Sindhughosh Class )
- Indonesia (2 Improved Kilo on order in 2006, Scheduled to arrived at 2009)
- Iran (3 Kilo)[3]
- Libya has decided to buy Kilo-636 submarines. An order is expected soon.
- Venezuela has arranged to buy three Kilo-636 submarines at a cost of approximately $1 billion. [4]
