Reach the fire before it reaches scale.
The M3 HH heavy-lift UAV is engineered to deliver over 500,000 litres of suppressant per day per system — reaching remote ignitions fast, dropping with precision, and flying when crewed aircraft stand down.
Suppression that
can't keep up
Wildfire response is straining against legacy systems that don't scale — just as fires grow more frequent and severe.
Frequency & severity
Record seasons are overwhelming conventional aerial fleets.
Scarce aircraft
Crewed bombers and helicopters are limited and in global demand.
Slow response
Remote ignitions grow into complexes before crews can reach them.
High operating cost
Crewed flight hours are expensive — and put pilots at risk.
Open-water dependency
Bucket and skimmer operations are grounded without a nearby water source.
Night stand-down
Most crewed assets cannot fly suppression after dark — fires don't stop.
M3 HH —
the heavy hauler
A heavy-lift autonomous aircraft purpose-built for suppression: internal-combustion endurance, VTOL launch from anywhere, and onboard suppressant that removes the open-water reload cycle entirely.
- Suppressant payload1,000KG
- System throughput500kL / DAY
- Operational range800KM
- LaunchVTOLNO RUNWAY
- Operations24/7DAY / NIGHT
- Water sourceOnboardNO OPEN WATER
// M3 HH design targets, validated progressively through the M1 and M2 flight-test programs.
Autonomous,
end to end
Detect & task
Ignition detected and confirmed; the system is tasked to coordinates within minutes.
Launch anywhere
VTOL departure from a staging pad near the fire — no runway, no water source.
Precision drop
Autonomous run onto hotspots with up to 1,000 kg of suppressant, day or night — every release authorized by a supervising operator.
Reload & repeat
Fast turnaround at the staging area keeps a continuous suppression cycle in the air.
Where it fits
the fire line
| Method | Speed | Cost | Range | Open-water reload |
|---|---|---|---|---|
| WaterStrider | High | Low | High | None |
| Drone buckets | Low | Medium | Low | Yes |
| Bombers | High | Very high | High | Varies |
| Helicopters | High | High | High | Yes |
// Skimmers and bucket operations need open water nearby; land-based airtankers reload at fixed tanker bases. The M3 HH carries suppressant onboard and stages from any clearing. Ratings reflect WaterStrider's modelled remote-ignition scenario — methodology available in a briefing.
