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
Limited · 1 operator
In service since 2021. Status: active · ~30 built.
Lifecycle cost (est.)
$225M – $315M
Acquisition is only ~30% of lifecycle cost, operating & support dominate over ~30 yrs. Rough 2.5–3.5× the unit price.
Interoperability
Derived guidance from public data, export regime by country of origin, lifecycle from the GAO ~30% acquisition rule. Verify eligibility, pricing and offsets with the manufacturer and your acquisition authority.

Full specifications
Performance
Speed, range, altitude and engagement capability.
- Max speed
Maximum level speed. For aircraft this is at optimal altitude; for ground vehicles, top road speed. Higher means faster response and better kinematic performance.
- 2,660 km/h Top 4% of fighters
- Max speed (Mach)
Maximum speed as a multiple of the speed of sound. Mach 2+ is typical for air-superiority fighters.
- 2.5 Mach Top 5% of fighters
- Range
Maximum distance: ferry range for aircraft, operational range for vehicles, maximum engagement distance for missiles. Higher means more standoff or persistence.
- 3,900 km Stronger than 85% of fighters
- Combat radius
Distance an aircraft can fly, complete its mission and return without refueling. Roughly a third of ferry range.
- 1,200 km Stronger than 63% of fighters
- Service ceiling
Maximum operating altitude. Higher gives energy advantage and sensor horizon.
- 19,200 m Stronger than 85% of fighters
- Rate of climb
How fast the aircraft gains altitude. Higher means better energy recovery in combat.
- 254 m/s Stronger than 31% of fighters
- Thrust-to-weight
Engine thrust divided by loaded weight. Above 1.0 the aircraft can accelerate going straight up.
- 1.06 Stronger than 72% of fighters
Firepower
Armament, payload and guidance.
- Main armament
Primary weapon: main gun, cannon or missile type.
- 20 mm M61A1 Vulcan rotary cannon
- Hardpoints
External stations for weapons and pods. More means bigger and more flexible loadouts.
- 12 Stronger than 86% of fighters
- Weapons payload
Maximum ordnance weight the platform can carry. Higher means more strike capacity per sortie.
- 13,380 kg Top 1% of fighters
Protection
Armor, countermeasures and survivability.
- Countermeasures
Self-protection: chaff, flares, DIRCM, towed decoys, smoke dischargers, jammers.
- AN/ALQ-250 EPAWSS electronic warfare suite, chaff, flares, towed decoys
Physical
Dimensions, weight and crew.
- Length
Overall length including gun/probe where applicable.
- 19.43 m
- Wingspan
Wingtip-to-wingtip span.
- 13.05 m
- Height
Overall height. Lower profile is harder to spot and hit for ground vehicles.
- 5.63 m
- Empty weight
Weight without fuel, ammunition or crew.
- 14,300 kg
- Combat weight
Fully loaded weight. Lighter eases transport and bridging limits; heavier often means more armor.
- 36,700 kg
- Crew
Personnel required to operate. Fewer reduces exposure; autoloaders trade a loader for mechanical complexity.
- 2
Propulsion
Engine, power and fuel.
- Engine
Powerplant model and type.
- 2x General Electric F110-GE-129 or Pratt & Whitney F100-PW-229 afterburning turbofans
- Engines
Number of engines. Twin-engine gives redundancy at higher cost.
- 2
- Thrust
Total engine thrust (with afterburner where applicable).
- 129 kN Stronger than 69% of fighters
- Fuel capacity
Internal fuel volume.
- 7,900 L
- Propulsion type
Turbofan, turboshaft, diesel, gas turbine, solid-fuel rocket, ramjet…
- Turbofan
Sensors & avionics
Radar, sensor suite and datalinks.
- Radar
Primary radar. AESA (active electronically scanned array) is the current state of the art.
- AN/APG-82(V)1 AESA
- Sensors
IRST, EO/IR turrets, laser designators, sniper pods, thermal sights.
- AN/AAQ-13 LANTIRN/Sniper targeting pod, AN/AAQ-33 Sniper, large-area-display cockpit
- Datalink
Network connectivity: Link 16, MADL, national datalinks. Enables cooperative engagement.
- Link 16, TTNT
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.
- $90,000,000 Stronger than 26% of fighters
- Units built
Total production run. Higher means proven manufacturing, mature logistics and spares availability.
- 30 Stronger than 12% of fighters
- Operator countries
Number of countries operating the system. More operators means broader support ecosystem.
- 1 Stronger than 23% of fighters
