Algeria has reportedly received two Kilo-class (Project 636) diesel-electric submarines from Russia, ordered as part of an arms package signed in mid-2006. The new arrivals take the fleet to four, French media say.
The package included 180 T-90 main battle tanks and 28 Sukhoi Su-30MK fighter aircraft.
The wikipedia notes the Project 636 “Varshavyanka” class is mainly intended for anti-shipping and anti-submarine operations in relatively shallow waters. GlobalSecurity notes the tear-drop hulled submarine is 72.6m long, 9.9m wide and can dive to 300 meters. The design has a displacement of 3076 tons. Underwater, it reportedly has a speed of up to 25 knots. The complement is 52 and the submarine has an endurance of 45 days. The boat is fitted with six 533mm torpedo tubes and carries up to 18 homing or wire-guided torpedoes, or 24 AM-1 mines.
The outer hull is covered with sound damping tiles and its machinery as well as design is regarded as very quiet. Designed by the Rubin Central Maritime Design Bureau of St Petersburg, the submarine entered service in 1982. The type was originally built at the Komsomolsk shipyard and lately by the Admiralty Shipyard in St Petersburg. It is in service with the navies of Russia, China, Vietnam, Iran, India and Poland, among others. Some 49 of the submarines have been built.
