Marcos Aerospace, a Greek aerospace startup based in Athens, has recently launched Quencher, an autonomous amphibious aircraft currently in what the company is describing as “the preliminary design phase.”
With a 4,500-litre water capacity*, Quencher is designed to conduct high-frequency aerial firefighting operations both day and night. Marcos Aerospace says patent application covering the platform’s core innovations have been filed.
The company announcement describes Quencher as “a deep-tech aerial firefighting platform”.
“Quencher integrates AI-assisted navigation, automated mission management, autonomous flight controls, and swarm coordination capability. The aircraft is optimized for continuous scooping operations from seas and lakes, as well as rapid refilling at designated ground stations, enabling relentless, around-the-clock initial attack and wildfire suppression,”
“Quencher is not merely a new aircraft; it represents a paradigm shift and a new category in aerial firefighting,”
said Marcos Caramalengos, aerospace engineer and founder of Marcos Aerospace.
One operator can coordinate up to five Quencher aircraft simultaneously. Maximum speed is 440 km/h, cruise speed is 360 km/h, built around a Pratt and Whitney PW127 turboprop engine.
Unlike conventional fixed-wing aircraft restricted to daylight, The Quencher is equipped for continuous day-and-night missions. Advanced sensors and AI flight control systems enable precision scooping and dropping in low-visibility conditions. This allows fires to be fought through the night, when winds are often calmer and conditions can be more favourable for suppression
A clarification of its current status on the website shows the concept is still in its very early days:
“Quencher is under development. The aircraft, systems, and operational concepts described on this site reflect the current design intent and program direction. Certification, testing, and operational deployment will follow applicable regulatory and safety requirements.”
Quencher is in Pre-Production Development Phase (2026–2029), which includes the design, engineering, and certification of the Quencher aircraft ahead of first production and commercial launch.
Marcos Aerospace says it is now open to strategic partnerships and discussions with civil protection authorities, industry stakeholders, and investors.
