Procurement snapshot
Availability & export
US ITAR-controlled
Export needs U.S. State Dept (DDTC) approval; end-use & re-transfer restrictions apply.
Channel: Foreign Military Sales (FMS) or Direct Commercial Sale
Fielded & proven
Operator data not public
Status: active · ~70,000 built.
Lifecycle cost (est.)
$420K – $588K
Acquisition is only ~30% of lifecycle cost, operating & support dominate over ~25 yrs. Rough 2.5–3.5× the unit price. Published studies put O&S anywhere from ~55% to ~70% of lifecycle cost depending on platform and method, which is why this is a band and not a single number. How we estimate this →

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. | 2 Mach |
|---|---|
| Range Maximum distance: ferry range for aircraft, operational range for vehicles, maximum engagement distance for missiles. Higher means more standoff or persistence. | 70 km |
Firepower
Armament, payload and guidance.
| Caliber Bore diameter of the main gun or rifle. Larger throws heavier projectiles; not simply better, ammunition commonality matters. | 227 mm |
|---|---|
| Warhead Warhead mass. Heavier generally means larger effect radius, at the cost of range. | 91 kg |
| Warhead type Blast-fragmentation, shaped charge (HEAT), penetrator, thermobaric or nuclear-capable. | Unitary high-explosive with multi-mode fuze (point detonation, delay or proximity airburst) |
| Guidance How the weapon finds its target: inertial, GPS/GLONASS, active/semi-active radar, infrared, laser, TV, wire. | GPS, Inertial navigation |
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. | $168,000 |
|---|---|
| Units built Total production run. Higher means proven manufacturing, mature logistics and spares availability. | 70,000 |
