Clemenceau and her sister ship served as the mainstays of the French fleet. During the carrier's career, Clemenceau sailed more than 1000000nmi during 3,125 days at sea. She was equipped to handle nuclear munitions to be delivered by her air complement and was later modified to fire nuclear-capable missiles. She took part in numerous exercises and cruises, seeing action during the Lebanese Civil War and Gulf War and in air operations over the former Yugoslavia.
The development of Clemenceau represented France's effort to produce its own class of multi-role aircraft carriers to replace the American and British ships provided at the end of World War II. The ship had a small but effective design, using some of the elements of United States carriers, but on a smaller scale. The vessels were given relatively heavy gun armament for their size, and some stability problems were encountered which required bulging the hull.
The Clemenceau-class aircraft carriers are of conventional CATOBAR design. The landing area was 165.5m (543feet) long by 29.5m (96.8feet) wide; it was angled at 8 degrees off of the ship's axis. The flight deck is 265m (869feet) long. The forward aircraft elevator was to starboard, and the rear elevator was positioned on the deck edge to save hangar space. The forward of two 52m (171feet) catapults was at the bow to port, the aft catapult was on the angled landing deck. The hangar deck dimensions were 152m (499feet) by 22- with 7m (23feet) overhead.[3]
Clemenceau went through a major refit from September 1977 to November 1978. She was refitted again with new defensive systems from 1September 1985 to 31August 1987, this included the replacement of four of the 100 mm guns with a pair of Crotale surface-to-air missile launchers. She was modified in 1978 to enable her aircraft to deliver several AN 52 bombs. In 1993 she was modified again to take nuclear capable Air-Sol Moyenne Portée missiles.[4]
Throughout the course of the aircraft carrier's lengthy career, it participated in the majority of French naval operations. From 12January to 5February 1962, Clemenceau participated in a NATO exercise known as BigGame with the United States Sixth Fleet in the western Mediterranean as an anti-submarine aircraft carrier. This was followed from 9March to 2April with another NATO exercise called OTAN Dawn Breeze VII, in the Gibraltar zone.
In January 1968, Clemenceau participated in the search for the lost submarine in the Mediterranean when contact was lost from port at Toulon. Minerve remained lost until French Defence Minister Florence Parly announced on 22 July 2019 that the wreck had been discovered.[5]
During the same year, the carrier was deployed to the south Pacific for French nuclear bomb testing in Polynesia including Canopus, the first French hydrogen bomb. With the deployment of the fleet, codenamed Alfa Force (French: [[:fr:Essais nucléaires français#Force Alfa (1966-1968)|Force Alfa]]), the naval force present around two atolls represented more than 40% of the tonnage of the entire French navy. Clemenceau was the flagship of a fleet composed of forty ships.[6]
During 1974–1977 Clemenceau was deployed off the African coast in the Indian Ocean in Operation Saphir I and Operation Saphir II in support of newly independent Djibouti. During the Lebanese Civil War Clemenceau was deployed in the East Mediterranean in 1983–84. The carrier rotated with, providing constant on-station air support to French peacekeepers in the Multinational Force in Lebanon FSMB and the United Nations Interim Force in Lebanon UNIFIL. The carrier's main support engagement was in Operation Olifant.[3] In 1987–1988 she participated in Operation Prométhée in the Gulf of Oman during the war between Iraq and Iran. The Promethée battle force (Task Force 623), included Clemenceau, the mine counter-measures support ship Loire, and s Meuse, Var, and Marne. In 1990, escorted by the cruiser and the tanker Var, she transported 40 helicopters (SA-341F/ -342 Gazelles, SA-330 Pumas), three Br-1050 Alizés and trucks to Iraq during Operations Desert Shield and Desert Storm.[7] The carrier was mainly engaged in Operation Salamandre in the Red Sea and the Arabian Sea during the conflict between Iraq and Kuwait. During 1993 to 1996 Clemenceau completed several tours including combat operations and air patrol over the former Yugoslavia in Operation Balbuzard [8] in order to support the UN's troops, then Salamandre in the Adriatic Sea during the Yugoslav Wars.
Clemenceau operated around the world with a career total of more than one million nautical miles traveled, the equivalent of circumnavigating the globe 48 times. The carrier has passed 3,125 days at sea, with 80,000 hours of function, and conducted more than 70,000 catapult-launches.
In 1983, the bâtiment was the first unit of the French Navy to embark female personnel. Three women were assigned on board: one maître principal, one secrétaire militaire and one premier maître.
Loyal to the tradition of the French Navy, Clemenceau welcomed on board numerous fine art painters, some for a week and others for up to two months.
On 31 December 2005, Clemenceau left Toulon to be dismantled in Alang, India despite protests about improper disposal and a lack of facilities for the management of toxic waste.
On 6January 2006, the Supreme Court of India temporarily denied access to Alang.[9] After having been boarded by activists, held by Egyptian authorities, and then transiting the Suez Canal on 15January, a court ruling by the Conseil d'État ordered Clemenceau to return to French waters.[10] Able UK, based at the Graythorp yard near Hartlepool received a disassembly contract to use accepted practices in scrapping the ship.[11] [12] The dismantling started on 18November 2009 and the break-up was completed by the end of2010.
