Full specifications

Performance

Speed, range, altitude and engagement capability.

Performance specifications
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 68% 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 24% of missiles

Firepower

Armament, payload and guidance.

Firepower specifications
Warhead

Warhead mass. Heavier generally means larger effect radius, at the cost of range.

11 kg
Stronger than 25% 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
