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 |
|---|---|
| Max speed (Mach) Maximum speed as a multiple of the speed of sound. Mach 2+ is typical for air-superiority fighters. | 2.5 Mach |
| 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 |
| Combat radius Distance an aircraft can fly, complete its mission and return without refueling. Roughly a third of ferry range. | 1,200 km |
| Service ceiling Maximum operating altitude. Higher gives energy advantage and sensor horizon. | 19,200 m |
| Rate of climb How fast the aircraft gains altitude. Higher means better energy recovery in combat. | 254 m/s |
| Thrust-to-weight Engine thrust divided by loaded weight. Above 1.0 the aircraft can accelerate going straight up. On a standalone engine record, this is the engine's own thrust divided by its dry weight, the standard figure of merit for jet engines. | 1.06 |
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 |
| Weapons payload Maximum ordnance weight the platform can carry. Higher means more strike capacity per sortie. | 13,380 kg |
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 |
| 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 |
|---|---|
| Units built Total production run. Higher means proven manufacturing, mature logistics and spares availability. | 30 |
| Operator countries Number of countries operating the system. More operators means broader support ecosystem. | 1 |
