French Navy

France's maritime armed service; operates nuclear submarines, Charles de Gaulle, and the Sirius MMCM drone.

In early June 2026 the French Navy embarked its Sirius autonomous minehunter aboard RFA Lyme Bay at Toulon alongside Britain's Ariadne, the first joint operation of the two navies' mine-hunting drones from one ship; by 23 June the pairing had reached the Gulf.

Background

The French Navy (Marine nationale) is the maritime branch of the French armed forces, responsible for nuclear deterrence at sea, power projection and mine-countermeasures across The Atlantic, Mediterranean, Pacific and Indian Ocean. It operates ballistic-missile submarines of the SNLE class, Barracuda-class attack submarines and the nuclear-powered carrier Charles de Gaulle, and is headquartered in Paris with major bases at Toulon and Brest.

France rejoined NATO's integrated military structure in 2009 after withdrawing in 1966, and remains a Permanent Member of the UN Security Council and an independent nuclear-weapons state; alongside the US and UK navies, it is one of three NATO fleets maintaining a continuous at-sea deterrent.

In the autonomous-systems domain, the Navy's Sirius uncrewed surface vessel has been developed since 2015 under the Anglo-French mine-countermeasures programme, with Thales supplying the sonar shared across both nations' drones.

The French Navy joins allied minehunting

At Toulon in early June 2026, the French Navy embarked Sirius aboard the Royal Fleet Auxiliary vessel Lyme Bay alongside the Royal Navy's Ariadne, the first time either service had operated its autonomous mine-hunter from a shared mothership rather than a national platform.

By 23 June the pairing had reached the Middle East, escorted by the destroyer HMS Dragon and two German vessels, giving the French Navy its most visible operational stake yet in the allied response to Iranian mining near the Strait of Hormuz.

Common Questions
What autonomous mine-hunting capability does the French Navy have?
The French Navy operates Sirius, an uncrewed mine-countermeasures surface vessel developed under the Anglo-French MMCM programme since 2015. In June 2026, Sirius was integrated with the Royal Navy's Ariadne aboard RFA Lyme Bay at Toulon in the first combined allied MMCM deployment from a single mothership.Source: Naval News
Does France have nuclear submarines?
Yes. France operates nuclear-powered ballistic-missile submarines (the SNLE class) for strategic deterrence and nuclear-powered attack submarines (the Barracuda class). France is one of three NATO navies with a nuclear deterrent at sea, alongside the US and UK.
How does the Anglo-French MMCM programme work?
The programme, running since 2015, developed a mine-countermeasures drone for each navy: France's Sirius and the UK's Ariadne, both using Thales sonar. In June 2026 both systems were integrated aboard RFA Lyme Bay at Toulon for the first time, testing whether joint allied autonomous MCM operations are feasible from a single mothership.Source: Naval News / USNI News
