Quencher delivers superior suppression economics through high-frequency operations, continuous availability, and a class-leading projected operating cost in the sub-7-tonne water-capacity category.

Cost per Tonne Delivered

Cost per tonne delivered calculated assuming representative seasonal utilisation. Includes operating costs and straight-line aircraft depreciation.

Quencher delivers water at a significantly lower total cost than conventional firefighting aircraft.

Under representative annual utilisation, the cost per tonne of water delivered is approximately €72, including acquisition, operation, maintenance, and depreciation.

This cost level enables:

• larger fleets rather than single high-value assets

• continuous day-and-night operations

• sustained pressure on the fire line

It represents the lowest cost per tonne delivered currently achievable in aerial firefighting.

Methodology note: Competitor operating cost figures are based on a synthesis of publicly available manufacturer data, operator disclosures, and independent industry analyses. Where precise data is not publicly available, conservative industry-standard assumptions have been applied consistently across all aircraft types.

Assumptions (for reference)

The €72 per tonne delivered figure is based on: 250 flight hours per aircraft per year, 6 water drops per flight hour, 4,500 litres per drop, all operating costs and aircraft depreciation included

Indicative daily operational availability during active wildfire suppression periods. Actual hours vary by location, season, and conditions.

Night-Time Economics

Continuous day-and-night operations further strengthen this economic effect.

Wildfires typically exhibit lower intensity and reduced spread during night-time hours due to cooler temperatures and higher humidity. By maintaining suppression through the night, Quencher applies sustained pressure during the most favourable conditions, reducing fire growth and shortening the time to containment.

Earlier containment directly lowers total suppression cost by limiting the scale and duration of both aerial and ground resources required.
