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

Established · 8 operators

In service since 1995. Status: active · ~279 built.

Lifecycle cost (est.)

$850M – $1.2B

Acquisition is only ~30% of lifecycle cost — operating & support dominate over ~35 yrs. Rough 2.5–3.5× the unit price.

Interoperability

No standardised NATO calibre / datalink detected in public specs.

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.

830 km/h
Stronger than 32% of transport aircraft
Cruise speed

Sustained economical speed. Determines transit time to station.

830 km/h
Stronger than 88% of transport aircraft
Range

Maximum distance: ferry range for aircraft, operational range for vehicles, maximum engagement distance for missiles. Higher means more standoff or persistence.

4,482 km
Stronger than 23% of transport aircraft
Service ceiling

Maximum operating altitude. Higher gives energy advantage and sensor horizon.

13,716 m
Top 3% of transport aircraft

Physical

Dimensions, weight and crew.

Length

Overall length including gun/probe where applicable.

53 m
Wingspan

Wingtip-to-wingtip span.

51.75 m
Height

Overall height. Lower profile is harder to spot and hit for ground vehicles.

16.79 m
Empty weight

Weight without fuel, ammunition or crew.

128,100 kg
Combat weight

Fully loaded weight. Lighter eases transport and bridging limits; heavier often means more armor.

265,350 kg
Crew

Personnel required to operate. Fewer reduces exposure; autoloaders trade a loader for mechanical complexity.

3
Cargo payload

Maximum cargo the transport can carry. Higher means more lift per sortie.

77,519 kg
Stronger than 88% of transport aircraft
Troop capacity

Number of embarked troops/passengers (IFV, APC, transport). Higher carries more.

102
Stronger than 55% of transport aircraft

Propulsion

Engine, power and fuel.

Engine

Powerplant model and type.

Pratt & Whitney F117-PW-100 turbofan
Engines

Number of engines. Twin-engine gives redundancy at higher cost.

4
Thrust

Total engine thrust (with afterburner where applicable).

180 kN
Propulsion type

Turbofan, turboshaft, diesel, gas turbine, solid-fuel rocket, ramjet…

Turbofan

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.

$340,000,000
Units built

Total production run. Higher means proven manufacturing, mature logistics and spares availability.

279
Stronger than 75% of transport aircraft
Operator countries

Number of countries operating the system. More operators means broader support ecosystem.

8
Stronger than 70% of transport aircraft
