France unveils De Grasse nuclear submarine with 270-day endurance (X @DGA)
France has just revealed its new attack nuclear submarine, called De Grasse, which is part of the Barracuda program.
This approximately $11.4 billion initiative aims to replace the old Rubis-class fleet by 2030 with six modern and more powerful submarines, built and maintained by the Naval Group in partnership with TechnicAtome.
The new submarine, measuring 99 meters in length and weighing 5,200 tons, features a pressurized water reactor that provides endurance for over 270 days on continuous patrols.
In addition to the extended endurance, these submarines are equipped with advanced precision weapons, including cruise missiles capable of striking targets over a thousand kilometers away, SM39 Exocet anti-ship missiles, and heavy F21 torpedoes. This technology represents a significant leap in France’s defense capabilities, allowing greater flexibility and resilience in various missions.
This enhancement of France’s military capabilities comes amid an intensified arms race in Europe driven by the war between Russia and Ukraine. The modernization of the French nuclear fleet also contributes to strengthening NATO’s strategic presence in the North Atlantic and the Mediterranean, demonstrating a clear response to geopolitical tensions and challenges in the region.
