The Quencher – Day and Night Firefighter

The world’s first unmanned amphibious water bomber.

The future of aerial firefighting is continuous day-and-night drops — affordable to acquire, economical to operate, with no crews at risk, and fleets of dispersed aircraft ready to respond within minutes.

Quencher is Marcos Aerospace’s flagship autonomous amphibious firefighting aircraft — designed to operate where manned aviation reaches its limits.

Carrying up to 4,500 litres of water, Quencher combines endurance, precision, and rapid redeployment in a single integrated platform. Its fully autonomous flight system allows continuous day-and-night suppression, while the advanced hull design enables operations from both inland lakes and open sea up to Beaufort Force 6 conditions.

Built around a Pratt & Whitney PW127 turboprop engine, Quencher delivers exceptional performance at altitude, reaching fire zones up to 2,800 metres and completing seven scoops per mission. Constructed from high-strength aluminium alloys and optimized for maintainability, it achieves a lower lifecycle cost than any conventional firefighting aircraft.

Developed and engineered entirely by Marcos Aerospace, Quencher represents a new generation of aerial resilience — a system that combines aerospace precision with operational autonomy to meet the world’s escalating wildfire challenges.

Delivers a powerful 4,500-liter water drop in every cycle — scooped in under 15 seconds from lakes, rivers, or the sea.

The first water bomber capable of continuous day-and-night firefighting, with zero risk to human crews.

AI-assisted swarm technology allows a single operator to supervise up to five aircraft at once, maximizing efficiency.

Affordable to acquire and economical to operate — enabling nations to build larger, more dispersed fleets.

Quencher combines low CO₂ per tonne of water delivered with earlier night-time fire containment, producing a compound reduction in both operational and wildfire-generated emissions.
