Performance
Speed, range, altitude and engagement capability.
| Max speed (Mach) Maximum speed as a multiple of the speed of sound. Mach 2+ is typical for air-superiority fighters. | 0.85 Mach |
|---|---|
| Range Maximum distance: ferry range for aircraft, operational range for vehicles, maximum engagement distance for missiles. Higher means more standoff or persistence. | 124 km |
Firepower
Armament, payload and guidance.
| Warhead Warhead mass. Heavier generally means larger effect radius, at the cost of range. | 221 kg |
|---|---|
| Warhead type Blast-fragmentation, shaped charge (HEAT), penetrator, thermobaric or nuclear-capable. | Penetrator blast-fragmentation |
| Guidance How the weapon finds its target: inertial, GPS/GLONASS, active/semi-active radar, infrared, laser, TV, wire. | Active radar homing, GPS/INS mid-course update |
Physical
Dimensions, weight and crew.
| Length Overall length including gun/probe where applicable. | 4.6 m |
|---|---|
| Combat weight Fully loaded weight. Lighter eases transport and bridging limits; heavier often means more armor. | 691 kg |
Propulsion
Engine, power and fuel.
| Propulsion type Turbofan, turboshaft, diesel, gas turbine, solid-fuel rocket, ramjet… | Turbojet with solid rocket booster |
|---|
Program
Cost, production scale and operators.
| Unit cost Approximate flyaway/unit cost where public. Defense pricing varies hugely by contract, offsets and configuration. Lower is cheaper. | $1,200,000 |
|---|---|
| Units built Total production run. Higher means proven manufacturing, mature logistics and spares availability. | 7,500 |
| Operator countries Number of countries operating the system. More operators means broader support ecosystem. | 30 |
