France has carried out the first operational firefighting mission by an Airbus A400M Atlas, using the military transport to lay retardant lines against the wildfire burning through the Gironde department.
The French Air and Space Force aircraft performed its first drop on the afternoon of July 25, 2026, near Lacanau, toward Sainte-Hélène. The mission marked the first time the A400M’s experimental firefighting kit had been deployed against an active wildfire.
Congratulations to the @Armee_de_lair and Sécurité Civile @SecCivileFrance for the first successful #A400M deployment to fight the wildfires in South West of France.

Prime Minister Sébastien Lecornu had ordered the aircraft’s deployment earlier that day, bringing the capability into operational use several days ahead of the timeline announced by the government. Technical preparations and crew qualification had begun on July 20, with the first field deployment initially expected within around ten days.
The fire, which began near Saumos on July 22, had burned approximately 42,000 hectares by July 26. Nearly 220,000 people had been evacuated across 23 communes, while 240 homes had been destroyed and 75 firefighters injured, according to the Gironde prefecture. The A400M was due to be committed again on July 26 alongside 18 other aerial firefighting assets.
Twenty metric tons laid ahead of the flames
The roll-on/roll-off kit requires no structural modification to the aircraft and allows it to release up to 20 metric tons of retardant in a single pass. The French government describes that as the equivalent of two drops by a Dash 8-Q400MR, the largest aircraft in the country’s civil-protection firefighting fleet.
Rather than attacking flames directly, the A400M is intended to operate ahead of the fire, laying long retardant lines around vulnerable areas to slow its advance and support firefighters on the ground.
The aircraft cannot scoop water from lakes or the sea like a Canadair CL-415 and must return to an airfield to refill its tank. Its role is therefore complementary to that of dedicated water bombers capable of conducting faster, repeated rotations over a fire.
Airbus first demonstrated the kit in Spain in July 2022, releasing 20 metric tons of water in less than 10 seconds. Further accuracy trials were conducted at Nîmes in April 2025 with France’s Directorate General for Civil Security and Crisis Management.
Spain announced on May 21, 2026, that it would equip part of its own A400M fleet with the same system.
From prototype to operational deployment
The July 25 mission completed an unusually rapid transition from experimental equipment to an initial operational capability.
The French Interior and Armed Forces ministries signed an agreement with Airbus on July 17 to make an aircraft and drop kit available on an experimental basis. Crew qualification began three days later, followed by a second trial drop near Air Base 123 Orléans-Bricy on July 24 and the first operational mission the next afternoon.
Evaluation work has been underway since 2024 between the French Air and Space Force’s Military Air Expertise Center, Airbus Defence and Space and the civil-security directorate.
The French Air and Space Force operates more than 25 A400Ms from Orléans-Bricy. The government has consistently presented their firefighting use as a temporary reinforcement rather than a substitute for France’s dedicated fleet of Canadairs, Dash 8s, Air Tractors and water-bombing helicopters.
The aircraft is being employed through the armed forces’ wildfire-support mission, which forms part of the interministerial Héphaïstos protocol activated each summer to support French civil-protection authorities.
