Agosta
Displacement: Agosta 1490 tons surfaced, 1740 tons submerged.
Dimensions: 67.6 x 6.8 x 5.5 meters (222 x 22 x 18 feet)
Armament: 4 21 inch torpedo tubes (16 F 17 torpedoes & Harpoon SSM or 28 mines)
Propulsion: Agosta: single shaft diesel electric drive; two SEMT-Pielstick diesel generators; one Jeumont-Schneider electric motor; 2540bhp for 12.5kts surfaced, 2990hp for 17.5kts submerged.
Maximum Depth: ??? meters
Description: The Agosta was designed to replace the Daphne class submarines in French naval service. The new design was larger than the Daphne and incorporated streamlining lessons from US experience with the Albacore hullform. battery capacity was doubled over previous French submarines giving these boats very good underwater endurance. This submarine is a double-hulled design. The main motor can provide 4725hp for short periods, giving a speed of 20.5kts.

Rubis-AMETHYSTE class

Displacement: 2,670 tons submerged
Dimensions: 73.6 x 7.6 x 6.4 meters (241 x 25 x 21 feet)
Armament:6 21 inch torpedo tubes (14 Exocet & torpedoes)
Propulsion: Turbo-electric, 1 reactor, 1 shaft, 9,500 shp, 25 knots
Maximum Depth:350 meters
Description: Very first nuclear attack submarine built in France, the Rubis was launched in 1976 and commissioned in 1983. Original plans scheduled the building of 8 units, but budget restriction brought their number to 6.
The 5th unit, S605 Améthyste, is an upgraded version. Améthyste is not only the name of a gemstone, it's an acronym for "AMElioration Tactique, HYdrondynamique, Silence, Transmissions, Ecoute"(Tactical, hydronynamical, Silent, Transmissions and Sensors Improvement). This version is fitted with a linear towed array working on low frequencies. Automation of some tasks are also part of the improvements. All Rubis class have been upgraded to the Améthyste standard, but the first one which will be replaced in 2010 by a new class of submarines called "Barracuda".

L'Inflexible (Le Redoutable) class

Displacement: 14,120 tons submerged
Dimensions: 138 x 12.5 x 12.5 meters (452.5 x 41 x 41 feet)
Armament:16 MSBS(Sea to Shore Ballistic Strategic) ballistic missiles, 4 21 inch torpedo tubes (12 Exocet & torpedoes)
Propulsion: Steam turbines, 1 reactor, 1 shaft, 41,500 shp, 25+ knots
Maximum Depth:300 meters
Description: In 1958, French President Charles de Gaulle took the decision to grant France a nuclear deterrence. This finalized with the Military Program Law 1960-1964.The first unit, Le Redoutable was ordered on May the 16th,1963 and launched on March the 29th,1967.
Originally fitted with M-1 Ballistic missiles, this class saw all of further developments, with Le Foudroyant equipped with improved M-2 as it was commissioned, Le Tonnant with M-20(last of the first generation missiles) and L'Inflexible with M-4, all other subs but the decommisionned Redoutable being fitted with these missiles as of 1995.

Le Triomphant class

Displacement: 14,120 tons submerged
Dimensions: 138 x 12.5 x 12.5 meters (452.5 x 41 x 41 feet)
Armament:16 MSBS(Sea to Shore Ballistic Strategic) ballistic missiles, 4 21 inch torpedo tubes (12 Exocet & torpedoes)
Propulsion: Steam turbines, 1 reactor, 1 shaft, 41,500 shp, 25+ knots
Maximum Depth:+300 meters
Description:
The 6th Military Program Law laid the basis of an improved version of Le Redoutable class, dubbed "new generation". This was to take into account the fact the original design was from the 60es. Improvements were mainly around discretion, thus the overall weight of the submarines climbed from 8,000 to 13,000 tons. As other French submarines, automation allowed the reduction of the crew from 135 to 111 and electronics now improves detection abilities.
Fitted with new generation of French nuclear missiles M-45, the last unit will be fitted with an improved missile M-51.
Belonging to the Force Océanique Stratégique( Strategic Ocean Force), at least 2 submarines are at sea at every moment, ensuring French independance through nuclear deterrence.
