Full specifications
Performance
Speed, range, altitude and engagement capability.
- 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.
- 278 km/h Stronger than 18% of helicopters
- Cruise speed
Sustained economical speed. Determines transit time to station.
- 220 km/h Bottom 3% of helicopters
- Range
Maximum distance: ferry range for aircraft, operational range for vehicles, maximum engagement distance for missiles. Higher means more standoff or persistence.
- 550 km Stronger than 33% of helicopters
- Service ceiling
Maximum operating altitude. Higher gives energy advantage and sensor horizon.
- 4,880 m Stronger than 32% of helicopters
- Rate of climb
How fast the aircraft gains altitude. Higher means better energy recovery in combat.
- 12 m/s Stronger than 59% of helicopters
Firepower
Armament, payload and guidance.
- Hardpoints
External stations for weapons and pods. More means bigger and more flexible loadouts.
- 2 Bottom 5% of helicopters
Protection
Armor, countermeasures and survivability.
- Armor
Armor technology: composite, modular, ERA-fitted, uranium-ceramic. Exact compositions are classified.
- Limited armored cockpit protection
- Countermeasures
Self-protection: chaff, flares, DIRCM, towed decoys, smoke dischargers, jammers.
- radar/laser warning receivers
Physical
Dimensions, weight and crew.
- Length
Overall length including gun/probe where applicable.
- 12 m
- Height
Overall height. Lower profile is harder to spot and hit for ground vehicles.
- 3.8 m
- Empty weight
Weight without fuel, ammunition or crew.
- 2,450 kg
- Combat weight
Fully loaded weight. Lighter eases transport and bridging limits; heavier often means more armor.
- 4,000 kg
- Crew
Personnel required to operate. Fewer reduces exposure; autoloaders trade a loader for mechanical complexity.
- 2
Propulsion
Engine, power and fuel.
- Engine
Powerplant model and type.
- 2x Mitsubishi TS1-M-10 turboshaft, 950 hp each
- Engines
Number of engines. Twin-engine gives redundancy at higher cost.
- 2
- Engine power
Engine output power. Higher moves more weight faster.
- 950 hp Stronger than 21% of helicopters
- Propulsion type
Turbofan, turboshaft, diesel, gas turbine, solid-fuel rocket, ramjet…
- Turboshaft
Sensors & avionics
Radar, sensor suite and datalinks.
- Sensors
IRST, EO/IR turrets, laser designators, sniper pods, thermal sights.
- Mast-mounted electro-optical/infrared sight, helmet-mounted display
- Thermal imaging
Thermal sights for night and obscured-visibility operations.
- Yes
Program
Cost, production scale and operators.
- Units built
Total production run. Higher means proven manufacturing, mature logistics and spares availability.
- 38 Stronger than 17% of helicopters
- Operator countries
Number of countries operating the system. More operators means broader support ecosystem.
- 1 Stronger than 18% of helicopters
