History
Development
In October 1998, the '' Delegation Générale pour l'Armement'', the French government's defense procurement agency, established an integrated project team consisting of the Naval Staff, DCN (now known as Naval Group), Technicatome and the '' Commissariat à l'Énergie Atomique'', a regulatory body that oversees nuclear power plants, to oversee a program the design of a new attack submarine class, called Barracuda. DCN was to be the boat's designer and builder while Technicatome (since acquired by Areva) was to be responsible for the nuclear power plant. The two companies were to act jointly as a single prime contractor to share the industrial risks, manage the schedules, and be responsible for the design's performance and costs, which at the time was estimated to be US$4.9 billion.
On 22 December 2006, the French government placed a €7.9 billion order for six ''Suffren'' submarines with Naval Group and their nuclear power plants with Areva-Technicatome. According to the DGA “Competition at the subcontractor level will be open to foreign companies for the first time.” According to the contract, the first boat was to commence sea trials in early 2016, with delivery occurring in late 2016/early 2017. This was to be followed by entry into service in late 2017. However, this timetable for service entry was later pushed back into the early 2020s.
The first boat of the class, ''Suffren'', became fully operational in June 2022. The second boat of the class, ''Duguay-Trouin'', also suffered delays but began sea trials on 26 March 2023, performing her first dive on 27 and 28 March. The submarine was formally delivered to the French Navy in August 2023. In early 2024, '' Duguay-Trouin'' deployed to the Caribbean as part of her ongoing trials and was declared fully operational in April 2024. The third submarine in the class, '' Tourville'', began her sea trials in July 2024 and was delivered in November 2024.
Description
Barracudas will integrate technology from the , including pump-jet propulsion. This class reportedly produces approximately 1/1000 of the detectable noise of the boats, and they are ten times more sensitive in detecting other submarines. They will be fitted with torpedo tube-launched MdCN cruise missiles for long-range (well above ) strikes against strategic land targets. Their missions will include anti-surface and

, land attack, intelligence gathering, crisis management and special operations.
The Barracuda class nuclear reactor incorporates several improvements over that of the preceding ''Rubis''. Notably, it extends the time between refueling and complex overhauls (RCOHs) from 7 to 10 years, enabling higher at-sea availability.
In support of special operations missions, the Barracuda can also accommodate up to 15 Commandos Marine. It integrates a removable dry deck shelter aft of the sail able to embark the commandos' new generation PSM3G Swimmer Delivery Vehicle (ECA Special Warfare Underwater Vehicle).
Specifications
Designed by Naval Group and TechnicAtome, the Barracuda integrates the following systems:
Note: The Antenne Linéaire Remorquée à technologie Optique (ALRO) under development by Thales for the SNLE 3G is expected to replace the ETBF DSUV 62C towed array sonar on the Barracuda-class submarines.

. Construction was expected to begin in 2023. The class would have been known as the ''Attack''-class submarine with the first vessel named HMAS ''Attack''.
On 16 September 2021, Australia cancelled the ''Attack''-class project and entered into a partnership with the United States and United Kingdom to obtain nuclear submarine technology ( SSN-AUKUS). The reactors run on weapons-grade uranium, are sealed and last for the thirty three years. The ones France uses, on the other hand, have to be serviced every ten years since it switched from weapons-grade to low-enriched uranium (LEU) to fuel its nuclear-powered submarines from the onward; this therefore requires a domestic nuclear industry, which Australia lacks.

as one of the three competitors in the ''Walrus''-class replacement program. The design was competing against the SaabA26 submarine and the TKMSType 212 submarine. On 15 March 2024 State Secretary for Defence Christophe van der Maat announced that Naval Group had been selected as the winning bid. The boats will be known as the ''Orka'' class, with the first two planned to be delivered within ten years of the contract signing.
