   The Scorpene class submarine was developed by DCN of France and Izar (formerly Bazan) of Spain. It is based on the proven Amethyste class of the French Navy.

   The first two units were ordered by Chile to be constructed in France and Spain for commissioning in 2005 and 2006 as the O'Higgins and Carrera, replacing two Oberon class boats. The Malaysian navy placed a contract for two Scorpene class submarines in June 2002. After construction in France and Spain both boats entered service in 2009.

   France and India also signed an agreement for the latter to build six Scorpene class boats at the state-owned Mazagon Docks in Bombay, with technical aid from the French DCN and Thales companies. The boats are to be completed on 2016-22 with SM.39 Exocet underwater-launched anti-ship missiles. Construction started in 2009.

   In 2008 Brazil ordered four submarines and one more hull, which will be fitted with an indigenous nuclear propulsion system. Construction started in 2010.

   As ordered for the Chilean navy, the Scorpene class submarine not have a towed-array sonar but are equipped with flank-array sonar. The six 533-mm bow torpedo tubes are capable of launching German SUT torpedoes, F-17 Mod 2, Mk 48 or, in Chilean service, Black Shark 184 Mod 3 torpedoes, as well as the SM.39 Exocet anti-ship missile. The tubes possess a salvo launch capability, and use a positive-discharge system by air turbine pump. The submarine's weapon complement is 18 torpedoes and missiles, or 30 mines. Handling and loading of weapons is automated.

   The SUBTICS combat management system, with up to six multi-function consoles and a central tactical table, is located with the platform-control facilities. SUBTICS comprises a command and tactical data-handling system, a weapon control system and a suite of integrated acoustic sensors, interfaced with the air/surface detection sonar and the navigation system.

   The boat has a high level of automation. A crew of 32 men is just half the number, comparing with earlier generation submarines.

   Submarine is available with basic or shorter hull, designed for improved maneuverability and lower signature. Hull of the Scorpene was designed for quiet running.

   The Scorpene class submarines feature diesel propulsion. They are powered by four diesel generators, developing more than 2 500 kW. Some vessels were ordered with an Air-Independent Propulsion system (AIP). Submarine has a range of 6 500 nautical mines (12 000 km) at 8 knots surfaced or 550 nm (1 020 km) at 5 knots submerged. Usually food supplies carried are sufficient for 50 days. Submarines with AIP system are capable of remaining submerged for three times longer than Scorpenes with conventional propulsion. They are sometimes referred as diesel-electric attack submarines.
