Latecoere Partners With HYNAERO on Fregate-F100 Water Bomber

French aerostructures manufacturer Latecoere and Bordeaux-based startups HYNAERO SAS established a strategic partnerships on August 18, 2026, to advance the development of the Fregate-F100 amphibious water bomber. The collaboration pairs an established aerospace supplier with a new entrant aiming to build a European successor to the legacy Canadair firefighting fleet.

In a press release announcing the agreement, Latecoere confirmed it will supply technical expertise to guide the aircraft through its design, certification, and maintainability phases. The Fregate-F100 program targets a significant capability increase over existing aerial firefighting platforms to address the growing severity of global wildfires.

Technical specifications and development roles

Latecoere’s involvement brings established industrial processes to HYNAERO, which was founded in 2023. The partnership will also see Latecoere assist with the global commercial promotion of the aircraft.

“Latecoere will provide technical exchanges and advice to support the design, certification and maintainability of the aircraft,” the company stated, adding that it will also support promotional efforts to potential customers worldwide.

The Fregate-F100 is designed to carry a water payload of 10 tonnes. This represents a 67 percent capacity increase compared to the De Havilland Canada CL-415. The aircraft is projected to cruise at 250 knots and requires 12 seconds to scoop a full load of water from a lake or ocean surface.

HYNAERO Co-founder and President David Pincet emphasized the importance of standardized operations for the new platform. According to reporting by Aviation International News, Pincet noted that the company recognized the need for a common doctrine from the outset to ensure the mission system baseline remains interoperable across different operators.

Funding, timeline, and market dynamics

The global aerial firefighting sector relies heavily on the De Havilland Canada CL-215 and CL-415 amphibious aircraft. Production of the CL-415 ended in 2015, leaving operators with an aging fleet and limited replacement options.

To fund the concept and preliminary design phases of the Fregate-F100, HYNAERO secured €117 million in a combined seed and Series A funding round in early 2026. The company estimates the program could generate more than 2,500 direct and indirect jobs over its lifespan.

HYNAERO has scheduled the preliminary design review for autumn 2028. The company targets early 2031 for the first test-flights, followed by initial customer deliveries in late 2032. This schedule represents an adjustment from earlier French government projections, which had outlined a target first flight in 2029.

The manufacturer has already secured letters of intent from the French Civil Security agency and two private operators. The Latecoere agreement joins existing strategic partnerships with Airbus Defence and Space and Altitude Aerospace.

AirPro News analysis

We view the addition of Latecoere to the Fregate-F100 program as a critical step in maturing HYNAERO from a conceptual startup into a viable original equipment manufacturer. Developing a clean-sheet amphibious aircraft involves complex hydrodynamic and aerodynamic engineering challenges, alongside stringent European Union Aviation Safety Agency (EASA) certification requirements. By integrating an experienced aerostructures partner early in the preliminary design phase, HYNAERO mitigates significant technical risk. The market demand for a CL-415 replacement is clear, but the revised 2031 first flight target reflects the industrial reality of bringing a specialized, heavy-payload amphibious platform to market.
