Toulon
France's principal naval base on the Mediterranean coast; homeport of the French Navy's Mediterranean fleet.
In early June 2026, Toulon hosted the first joint embarkation of French and British autonomous minehunters, now positioned in the Gulf awaiting Oman's order to begin clearing mines near the Strait of Hormuz.

Autonomous Systems: Land & SeaBackground
Toulon is the largest naval base in the Mediterranean and Western Europe, sited in the VAR department on France's south coast. Naval use dates to the late sixteenth century, when Henry IV ordered an arsenal built there; expansion under Cardinal Richelieu and Colbert made it the centre of French Mediterranean sea power.
Around 20,000 military and civilian personnel work at the base today, which holds more than 60% of French Navy tonnage, including the aircraft carrier Charles de Gaulle. The arsenal contains France's principal naval dockyards and drydocks, and Toulon serves as the operational home of the Mediterranean Fleet, from which France projects power into The Atlantic, Indian Ocean and Indo-Pacific.
Under the Lancaster House defence treaties, Toulon is a regular staging point for Royal Navy vessels working alongside French counterparts, giving the base a durable role in Anglo-French maritime cooperation beyond any single deployment.
Toulon staged the stalled Gulf mission
On 1 June 2026, RFA Lyme Bay called at Toulon to embark France's Sirius autonomous minehunter alongside Britain's RNMB Ariadne, the first time either navy had sailed with two allied robot minehunters aboard one ship. For Toulon, the call underlined the base's role as the hinge of Anglo-French naval cooperation: the point where interoperable systems change custody rather than merely visit.
Lyme Bay reached the Middle East on 23 June still carrying both drones, and Oman authorised clearance work on its southern Hormuz route in early July, before a tanker strike on 7 July stalled the start. The mission that Left Toulon remains parked rather than under way.
