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. | 20 Mach |
|---|---|
| Range Maximum distance: ferry range for aircraft, operational range for vehicles, maximum engagement distance for missiles. Higher means more standoff or persistence. | 9,600 km |
Firepower
Armament, payload and guidance.
| Warhead type Blast-fragmentation, shaped charge (HEAT), penetrator, thermobaric or nuclear-capable. | up to 10 MIRV (W87) |
|---|---|
| Guidance How the weapon finds its target: inertial, GPS/GLONASS, active/semi-active radar, infrared, laser, TV, wire. | Inertial (AIRS, Advanced Inertial Reference Sphere) |

Dimensions, weight and crew.
| Length Overall length including gun/probe where applicable. | 21.8 m |
|---|---|
| Width Overall width, matters for rail/road transport of vehicles. | 2.34 m |

|---|---|
| Propulsion type Turbofan, turboshaft, diesel, gas turbine, solid-fuel rocket, ramjet… | 3-stage solid |
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. | $70,000,000 |
|---|---|
| Units built Total production run. Higher means proven manufacturing, mature logistics and spares availability. | 114 |
| Operator countries Number of countries operating the system. More operators means broader support ecosystem. | 1 |
