Naval Group transferred Rubis (S639), the fifth Barracuda-class nuclear attack submarine, to its launch platform in Cherbourg on October 16, 2026. The milestone advances France's program to replace six aging Rubis-class submarines with four already delivered and the fifth expected by end-2027.
What's happening
- Rubis (S639) moved to the DME floating shiplift platform in Cherbourg for completion work and trials ahead of French Navy delivery.
- Four Barracuda-class submarines delivered between November 2020 and June 2026; fifth expected by end-2027 and sixth by 2030.
- The program engages 3,000 personnel across Naval Group and subcontractors including partner TechnicAtome, which develops nuclear reactor components.
Why it matters
- France's six-submarine replacement program addresses aging Rubis-class SSNs deployed since the 1980s, maintaining continuous nuclear attack submarine capacity for Atlantic and North Sea operations.
- Industrial continuity on the Barracuda program sustains the French nuclear submarine industrial base and supply chain across 800 Naval Group subcontractors and partner companies.
- Sea trials and delivery timeline determine when Rubis enters operational service, affecting French Navy force structure readiness through the program completion window.
Going deeper
- Rubis will undergo alpha trials by summer 2027 and quayside trials before sea acceptance, establishing readiness gates for delivery timing.
- DGA and Naval Group are developing an evolution roadmap called Evol SNA to maintain Barracuda-class capabilities over the next 30 years.
- Naval News reports DGA and Naval Group are working on SNA3G, a third-generation SSN concept, though it is not yet an official program.
The fine print
- Completion work, quayside trials and sea trials remain ahead before Rubis delivery to French Navy, with timing dependent on trial performance.
