Perle is a first-generation nuclear attack submarine of the French Navy. The boat is the sixth and last of the Rubis series. Construction began on the submarine on 27 March 1987. The boat was launched on 22 September 1990 and entered active duty service on 7 July 1993.
On 12 June 2020 at 10:35a.m., a fire started at bow of Perle, while in drydock for maintenance and repair at the military port of Toulon.[3] The fire was reported as under control at 9:36 PM.[4] Firefighters flooded the rear compartments of the submarine with foam. At least 30 specialist naval fighters and a fireboat were involved.[4] There were no reported injuries in the fire. Since the submarine's 48 megawatt pressurized water nuclear reactor had been removed when it entered the drydock in January 2020, there was no risk of radioactive contamination.[4]
In October 2020 it was announced that the submarine would be repaired using the forward section of her decommissioned sister boat, Saphir. The repair was to begin in January 2021 with envisaged completion in 2023.[5]
In October 2021, the joining of the forward section of Saphir with Perle was said to have been completed and the submarine was transferred from the Cherbourg shipyard back to Toulon to resume her original refit where it had been interrupted by the June 2020 fire. The joining of the forward section of Saphir to Perle involved about 100,000 hours of study and more than 250,000 hours of work. At the end of the process, the submarine's displacement increased by 68 tonnes and her length by about one meter.[6]
Perle was scheduled for continued work through 2022 with sea trials envisaged toward the end of the year and a return to operational service in the first half of 2023.[7]
2022 fire and return to operational service
While continuing refit in dry dock at the arsenal in Toulon, Perle experienced another fire on 26 September 2022. Prior to the fire, the submarine had been slated to return to service in the first quarter of 2023.[8] On 17 November 2022, the submarine left dry dock to continue her tests prior to an envisaged start of sea trials.[9] The submarine returned to sea in May 2023 for the start of post-refit sea trials.[10] In July she was declared ready to return to a regular operational cycle in the fleet until 2028.[11]
The Barracuda class is a nuclear attack submarine, designed by the French shipbuilder Naval Group for the French Navy. It is intended to replace the Rubis-class submarines. Construction began in 2007 and the first unit was commissioned on 6 November 2020. The lead boat of the class, Suffren, entered service on 3 June 2022.
The Rubis class is a class of nuclear-powered attack submarines operated by the French Navy. It comprises six boats, the first entering service in 1983 and the last in 1993. Two additional units originally planned were cancelled as a result of post-Cold War budget cuts. All six submarines of the Rubis class are based at Toulon and are part of the Escadrille de sous-marins nucléaires d'attaque. Smaller than contemporary designs of other major world navies, the Rubis class shares many of its system designs with the conventionally-powered Agosta class. In the late 1980s, the Rubis class was proposed to Canada in the context of their plan to acquire nuclear-powered submarines.
Le Rubis, initially named Provence, was a first-generation nuclear attack submarine and lead boat of the Rubis class of the French Navy, assigned to the attack nuclear submarine squadron.
Améthyste is a nuclear-powered attack submarine of the French Navy, the fifth of the Rubis type. The boat's name is a pun on a precious stone (Amethyst) and the acronym AMElioration Tactique, HydrodYnamique, Silence, Transmission, Ecoute. The boat is a major upgrade upon the initial design of the Rubis type, and earlier units have since been refitted to meet her standards.
Saphir was a first-generation nuclear attack submarine of the French Navy. Saphir was the second of the Rubis series. The boat was originally to be named Bretagne, but the name was changed to Saphir before commissioning in 1981.
Casabianca was a Rubis-class nuclear attack submarine of the French Navy. Laid down in 1981, she was launched in 1984 and commissioned in 1987. She was withdrawn from service in September 2023.
Émeraude is a nuclear attack submarine from the first generation of attack submarines of the French Navy. Having been in service since 1988, she is scheduled to be retired in 2024.
Le Triomphant is a strategic nuclear submarine of the French Navy; the submarine is the lead boat of her class commissioned in 1997 with the home port of Île Longue. The vessel carries sixteen strategic missiles, whose launch can only be authorized by the President of France.
Le Terrible is a Triomphant-class strategic nuclear submarine of the French Navy. The boat was launched on 21 March 2008
The Submarine Forces of France are one of the four main components of the French Navy. The force oversees all French submarines regardless of role.
The Saphir-class submarines were a class of six submarines built in France between 1926 and 1935 for the French Navy. Most saw action during World War II for the Vichy French Navy or the Free French Naval Forces. Three were captured by Italian forces but not used.
The French submarine Diamant was a Saphir-class submarine built for the French Navy in the mid-1930s. Laid down in July 1930, it was launched in May 1933 and commissioned in June 1934. Diamant was scuttled at Toulon on 27 November 1942 to prevent her capture by German forces, then refloated by Italian forces on 29 March 1943. On 22 June 1944, Diamant was bombed and sunk at Toulon by Allied aircraft.
The French submarine Nautilus was a Saphir-class submarine built for the French Navy in the mid-1930s. Laid down in August 1927, it was launched in March 1930 and commissioned in July 1931.
