The Russian Kilo Class submarine first entered service in the early 1980s. It was designed by the Rubin Central Maritime Design Bureau, St Petersburg. Subsequent developments have led to the current production versions, the Type 877EKM and the Type 636. The Kilo submarine was originally built at the Komsomolsk shipyard but is now constructed at the Admiralty Shipyard in St Petersburg. China has two Type 636 submarines. In September 2007, it was announced that Indonesia had placed an order for two Kilo Type 636 submarines, plus options to purchase up to eight more.In November 2007, Venezuela signed a memorandum of understanding for three Type 636 submarines to be delivered from 2012 to 2013. 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 U.S. 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.
