Naval Group has rolled out the fourth Barracuda nuclear attack submarine (SSN), named De Grasse, at its facility in Cherbourg, France. This significant advancement in the French Navy’s capabilities marks a key milestone in the fleet’s modernization efforts. Following the rollout, the submarine will undergo extensive outfitting and testing phases before it can embark on sea trials, which are scheduled to commence in 2026.
The De Grasse is the fourth unit in a series of six submarines that are set to replace the aging Rubis-class submarines. Notably, the third submarine, named Tourville, was delivered to the French defense procurement agency in November 2022. Tourville started its maiden sea trials in July 2024, aiming to evaluate its technical and operational capabilities before official integration into the French Navy.
Barracuda SSNs are engineered for multi-role operations, showcasing cutting-edge technology in propulsion, stealth, and combat efficacy. The submarines utilize a nuclear propulsion system, combining turbine and electric motor technologies to achieve remarkable operational capabilities. Capable of reaching submerged speeds of approximately 25 knots (29 miles or 46 kilometers per hour), the Barracuda class operates at depths exceeding 300 meters (985 feet).
In terms of weaponry, the Barracuda is well-equipped, featuring F21 heavyweight torpedoes for anti-ship and anti-submarine warfare, Exocet SM39 missiles targeted at surface vessels, and MdCN naval cruise missiles for land assaults. The integration of advanced communication systems allows for effective coordination in joint air and naval operations. Furthermore, these submarines are designed to operate with high acoustic discretion, advanced underwater detection capabilities, and extended mission endurance, making them formidable assets for France’s naval strategy.
The De Grasse measures 99 meters (325 feet) in length and features a beam of 8.8 meters (29 feet), culminating in a surface displacement of roughly 4,700 tonnes. As the French Navy transitions to the Barracuda class, the emphasis on modern warfare capabilities and enhanced operational flexibility is evident, signaling a strong commitment to maintaining strategic maritime superiority.
