France Submarine Capabilities

  • Barracuda Submarine Barracuda Submarine
  • Le Redoutable Submarine Le Redoutable Submarine
  • Le Triomphant Submarine Le Triomphant Submarine
  • Rubis/Améthyste Submarine Rubis/Améthyste Submarine

The French submarine fleet consists of nuclear-propelled attack (SSNs) and ballistic missile submarines (SSBNs). France decommissioned its last Agosta-class diesel-electric boat in 1999 without plans to replace the class with modernized diesel-electric vessels. This is despite France's pioneering role in the development of air independent propulsion (AIP) technology.[1]

The French Navy's area of operation includes the North Atlantic, the Mediterranean Sea, and the Indian Ocean. France also maintains a presence near the economic zones of its numerous overseas territories and former colonies, such as French Polynesia and New Caledonia in the South Pacific, the West Indies and French Guyana in the Caribbean Sea, Reunion Island and Mayotte in the South Indian Ocean, and Djibouti at the mouth of the Red Sea.[2]

Submarine Tables for France
 

France currently operates four Le Triomphant-class strategic missile submarines (SSBNs) based at Ile Longue, Brest. Since 1991, all six units from France's former fleet of Le Redoutable-class SSBNs have been progressively decommissioned, with the final vessel, L'Inflexible, completing its last deployment in 2007. [3] While plans originally called for the procurement of six Le Triomphant-class vessels to replace these older units, in 1991 this number was decreased to four. The final vessel of this project, Le Terrible, entered service in 2010 and is equipped with 16 new M-51 submarine-launched ballistic missiles (SLBMs) carrying four warheads each.[4] The previous three Le Triomphant-class submarines are currently equipped with M-45 SLBMs, each carrying six TN-75 nuclear warheads, but will be progressively adapted to carry the M-51 by 2017-2018.[5] Since France decided to dismantle its land-based ICBMs at Plateau d'Albion in 1996, its SSBN force is the nucleus of the country's strategic deterrent, and maintains a continuous at-sea presence.[6]

France also has six nuclear-powered Rubis/Améthyste-class attack submarines (SSNs) currently on active duty, based at Toulon. However, the class is to be gradually decommissioned and replaced with the newly developed Barracuda-class attack submarines, the first of which, Suffren, was ordered in December 2006 and is due to enter service in 2017. [7] The new class will feature improved communication capabilities and, more importantly, an increased force-projection capability based on cruise missiles.[8] France and Britain have jointly developed the Storm Shadow/Scalp EG cruise missile, which can fulfill this force projection requirement due to its high accuracy and effectiveness against hardened targets.[9] The attack boats' main task is the protection of France's SSBN force and carrier group via anti-submarine and anti-surface warfare. In addition to traditional sea control and sea denial operations, its attack submarines are tasked with special forces deployment, surveillance and intelligence gathering, and missions against piracy, narcotics, and human trafficking.[10]

About

The submarine proliferation resource collection is designed to highlight global trends in the sale and acquisition of diesel- and nuclear-powered submarines. It is structured on a country-by-country basis, with each country profile consisting of information on capabilities, imports and exports.

Understanding
the Nuclear Threat

Reducing the risk of nuclear use by terrorists and nation-states requires a broad set of complementary strategies targeted at reducing state reliance on nuclear weapons, stemming the demand for nuclear weapons and denying organizations or states access to the essential nuclear materials, technologies and know-how.
