Full specifications
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 Stronger than 24% of missiles
- Range
Maximum distance: ferry range for aircraft, operational range for vehicles, maximum engagement distance for missiles. Higher means more standoff or persistence.
- 124 km Stronger than 51% of missiles
Firepower
Armament, payload and guidance.
- Warhead
Warhead mass. Heavier generally means larger effect radius, at the cost of range.
- 221 kg Stronger than 64% of missiles
- 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 Stronger than 55% of missiles
- Units built
Total production run. Higher means proven manufacturing, mature logistics and spares availability.
- 7,500 Stronger than 67% of missiles
- Operator countries
Number of countries operating the system. More operators means broader support ecosystem.
- 30 Stronger than 89% of missiles
