TOULOUSE – Deep inside the carcass of a disused turboprop aircraft, engineer Jonathan Beck squeezes between rows of tanks as he demonstrates how his French startup plans to challenge ageing Canadair water-bombers in combatting European wildfires.

From the birthplace of Concorde to the laptops of a retired general in southern France or an architect in Belgium, designs for new or converted water-bombers have gained momentum after nearly 500,000 hectares burned across Europe this year.

A parliamentary panel warned last year that France’s existing fleet of aerial firefighters faced a “major crisis” and called for European alternatives to the rugged water-scooping Canadairs, which have dominated the market for decades.

At first glance, the task looks daunting. A water-scooper is partly a seaplane, the art of ⁠which has eroded over the years.

“We will have eight tons of water ⁠inside this aircraft,” former Airbus engineer Beck, who heads design at Positive Aviation, told Reuters, pointing to Y-shaped pipes that would draw water from new floats designed to skim over lakes or sea.
