[7] 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.

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.

[9] According to the DGA “Competition at the subcontractor level will be open to foreign companies for the first time.”[10] According to the contract, the first boat was to commence sea trials in early 2016, with delivery occurring in late 2016/early 2017.

[3] 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.

[19][20] Naval Group submitted a conventionally powered diesel-electric variation to the design – named the Shortfin Barracuda Block 1A, a derivative of the SMX Ocean concept – to the competitive evaluation process (CEP) phase of Australia's Collins-class submarine replacement.

"While exact details remain confidential, DCNS can confirm the Shortfin Barracuda is over 90 metres (300 ft) in length and displaces more than 4,000 tons when dived," said Sean Costello, CEO of Naval Group Australia.

[46] 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 Rubis class onward; this therefore requires a domestic nuclear industry, which Australia lacks.

On 15 March 2024 State Secretary for Defence Christophe van der Maat announced that Naval Group had been selected as the winning bid.
