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.
- 3.5 Mach Stronger than 64% of missiles
- Range
Maximum distance: ferry range for aircraft, operational range for vehicles, maximum engagement distance for missiles. Higher means more standoff or persistence.
- 15 km Stronger than 19% of missiles
Firepower
Armament, payload and guidance.
- Warhead
Warhead mass. Heavier generally means larger effect radius, at the cost of range.
- 11 kg Stronger than 23% of missiles
- Warhead type
Blast-fragmentation, shaped charge (HEAT), penetrator, thermobaric or nuclear-capable.
- Blast-fragmentation, active laser proximity fuze
- Guidance
How the weapon finds its target: inertial, GPS/GLONASS, active/semi-active radar, infrared, laser, TV, wire.
- Imaging infrared homing, High off-boresight lock-on
Physical
Dimensions, weight and crew.
- Length
Overall length including gun/probe where applicable.
- 3.1 m
- Combat weight
Fully loaded weight. Lighter eases transport and bridging limits; heavier often means more armor.
- 105 kg
Propulsion
Engine, power and fuel.
- Propulsion type
Turbofan, turboshaft, diesel, gas turbine, solid-fuel rocket, ramjet…
- Solid-fuel rocket
Program
Cost, production scale and operators.
- Operator countries
Number of countries operating the system. More operators means broader support ecosystem.
- 10 Stronger than 73% of missiles
