France Safran
Patroller
A tactical, long-endurance ISR drone built by Safran on the Stemme ASP S15 motor-glider airframe, selected by the French Army to replace the Israeli-built Harfang. It carries a Euroflir 410 electro-optical/infrared turret and can be fitted with SAR/MTI radar or communications-intelligence payloads, with certified operation in non-segregated European airspace. Also ordered by Greece.

| Max speed Maximum level speed. For aircraft this is at optimal altitude; for ground vehicles, top road speed. Higher means faster response and better kinematic performance. | 314 km/h |
|---|---|
| Cruise speed Sustained economical speed. Determines transit time to station. | 92 km/h |
| Service ceiling Maximum operating altitude. Higher gives energy advantage and sensor horizon. | 7,620 m |
| Endurance Time on station. Critical for UAVs and patrol platforms, higher means longer persistent coverage. | 30 h |
Firepower
Armament, payload and guidance.
| Hardpoints External stations for weapons and pods. More means bigger and more flexible loadouts. | 2 |
|---|---|
| Weapons payload Maximum ordnance weight the platform can carry. Higher means more strike capacity per sortie. | 250 kg |
Physical
Dimensions, weight and crew.
| Length Overall length including gun/probe where applicable. | 8.5 m |
