Scorpène submarines combine the latest advances in hull shape and modular construction with state-of-the-art technologies, including synchronous propulsion motor, two-stage turbo-charged diesel engine, high capacity batteries.
Acoustic discretion The overall architecture is optimized for reduced noise. The hull shape is designed for quiet running and to maximize the efficiency of the vessel's own acoustic arrays. Each item is selected for its silence, and equipment mountings and installations made quiet by design. Scorpène family DCN International proposes: - Scorpène Basic, already selected by two navies, with conventional diesel/electric propulsion. - Scorpène Basic-AIP offers basic Scorpène qualities plus Mesma AIP for improved endurance. - Scorpène Compact is ideal for operations in littoral waters. Uses diesel engines for surface propulsion, AIP for prime underwater propulsion, and diesel/ electric for added flexibility. New-generation combat system Scorpène's high-performance integrated combat system offers flexibility and reliability. Multifunction consoles give each operator full control over array deployment, surface sensors, weapons, and countermeasures. Scorpène submarines can launch a variety of 21-inch weapons, including wire-guided torpedoes and pop-up antiship missiles. Deep diving The choice of type 80 HLES high-yield steel for the pressure hull - the same as used for the French Navy's nuclear submarines - allows unlimited diving to more than 300 m while offering greater freedom for tactical manoeuvres. There is no limit on the number or duration of dives to maximum depth. Mesma AIP Scorpène's modular design readily accommodates the Mesma air-independent propulsion system during construction (Scorpène Basic-AIP) or at any stage of the cycle life. Mesma increases submerged endurance by a factor of 3 to 4. Risk of detection is radically reduced since the vessel spends much less time at snorkel depth recharging batteries. Integrated platform management system The Shipmaster IPMS moni-tors all submarine plant and subsystems. Functions such as piloting, diving/safety, and power/propulsion are fully integrated allowing officers and crew to concentrate on high-level tasks Reduced crew The highly automated IPMS and combat system reduce workloads to the point where a Scorpène with a crew of 30 is more effective than an earlier generation submarine with a crew of 50. Comfortable work areas and quarters provide excellent living conditions for optimal crew efficiency throughout the mission.

To date, 13 Agosta-class submarines have been ordered by France, Spain and Pakistan. The original design featured innovative architectural solutions and state-of-the-art equipment. More importantly, its inherent adaptability made it an excellent candidate for a thorough upgrade, in the early 1990s, resulting in the Agosta 90B. The upgrade - which focused primarily on the combat system - incorporates the latest sensors and computer technologies.

Missions Agosta-class submarines are ideal for missions ranging from anti-shipping and anti-submarine warfare to surveillance, intelligence gathering, mine-laying, special operations and training. French, Spanish and Pakistani Agosta-class submarines have successfully undertaken a wide variety of missions, including long patrols and major multinational exercises, in times of peace or during crises. They have operated worldwide from the Caribbean to the Mediterranean and from the Sea of Oman to the China Sea.
