Hynaero Secures €117M to Develop Next-Gen Amphibious Water Bomber

This article is based on an official press release from Hynaero.

French aerospace startup Hynaero has successfully closed a combined Seed and Series A funding round, securing €117 million ($135.2 million) to accelerate the development of its next-generation amphibious water bomber, the Fregate-F100. Announced on March 23, 2026, the funding marks a significant milestone in European efforts to modernize aerial firefighting capabilities amid a growing global megafire crisis.

According to the company’s press release, the investment round was led by Bpifrance and the Région Sud (Sud Provence-Alpes-Côte d’Azur Region), alongside an undisclosed private investor. The newly acquired capital is earmarked for finalizing the initial design phase of the aircraft and advancing the program toward its first physical prototype.

Founded in 2023 by David Pincet, a former fighter pilot, air force general, and former director of the French airpower fleet for forest firefighting, Hynaero aims to address the critical shortage and aging of current firefighting fleets. We note that Pincet’s firsthand experience with legacy aircraft directly informed the operational requirements of the Fregate-F100 project.

A New Era in Aerial Firefighting

The Fregate-F100 Capabilities

The Fregate-F100 is designed as a clean-sheet, twin-engine amphibious aircraft intended to replace and outperform existing legacy water bombers. Based on specifications provided in the Hynaero press release, the aircraft will feature a payload capacity of 10 tons of water (approximately 2,690 US gallons). The company notes this represents a roughly 70% capacity increase over the current industry standard, the Canadair CL-415 and DHC-515.

Performance metrics released by Hynaero indicate the Fregate-F100 will boast a cruising speed of 250 knots and a mission endurance of 2.5 to 3 hours. It is designed to operate up to 400 kilometers (approximately 220 nautical miles) from its base. Furthermore, the aircraft will incorporate modern aviation technologies, including fly-by-wire controls, a Heads Up Display (HUD), and a digital twin system for predictive maintenance.

The capital will be used to finalize the initial design phase of the Fregate-F100 (scheduled for completion by summer 2026) and to advance the program toward its first prototype, according to the official announcement.

Hynaero also highlights the aircraft’s multi-role adaptability. While purpose-built for firefighting, the Fregate-F100 is designed with removable seating and cargo space, allowing operators to reconfigure the airframe for passenger transport, maritime patrol, and search-and-rescue missions during off-peak fire seasons.

Strategic Backing and European Sovereignty

Airbus and Government Support

The development of the Fregate-F100 is heavily supported by major European aerospace and governmental entities. In early 2025, Airbus Defence and Space signed a Memorandum of Understanding (MoU) to partner with Hynaero. According to the project’s documentation, Airbus is providing crucial expertise in aero-structure design, flight controls, mission systems, industrial processes, and marketing. Jean-Brice Dumont, Executive VP at Airbus, previously noted that the Fregate-F100 completes Airbus’s range of firefighting capabilities and brings immense credibility to the project.

In addition to private and regional investment, the project has received backing from the French government, including a prior €7 million grant from the France 2030 public investment program, as well as support from the European Commission and the GIFAS aerospace association.

Economic Impact and Production Timeline

Job Creation in Istres

Hynaero is headquartered in Bordeaux (Merignac), but its manufacturing and assembly line will be established at the Jean Sarrail aeronautical hub in Istres, located in the Provence region. The company projects significant economic benefits from the program. According to their timeline, Hynaero plans to employ around 80 people by 2026, scaling to 300 by 2029.

During full production, the Istres assembly plant is expected to support 500 direct jobs and an estimated 2,000 indirect supply-chain jobs over the aircraft’s projected 30-to-40-year lifespan. Environmentally, the Fregate-F100 is designed to operate on Sustainable Aviation Fuel (SAF), which the company states will significantly reduce its carbon footprint.

The company has outlined a clear development timeline: following the completion of the initial aircraft design in the summer of 2026, Hynaero plans to occupy a 7,000 to 9,000 square meter hangar at the Istres air base in 2028. The first physical prototype is expected by 2029, with a target date for official launch and entry into service between 2031 and 2032.

AirPro News analysis

The €117 million capital injection into Hynaero represents a critical pivot in European civil defense strategy. For 50 years, the global aerial firefighting market has been effectively monopolized by the North American Canadair family (now De Havilland Canada). As climate change accelerates the frequency and intensity of megafires across Europe, evidenced by recent devastating seasons in France, Spain, and Sweden, reliance on an aging, foreign-built fleet has become a glaring vulnerability. For context, France currently operates only 12 Canadairs, which struggle with maintenance and availability issues.

By backing Hynaero, the French government and Airbus are making a calculated sovereignty play. The Fregate-F100 is not merely a commercial venture; it is a strategic asset designed to reclaim European industrial independence in specialized aviation. If Hynaero meets its 2031/2032 entry-into-service target, it could fundamentally disrupt the global water bomber market, offering a modernized, higher-capacity, and SAF-compatible alternative just as legacy fleets reach the end of their viable service lives.
