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.

Lifecycle cost (est.)

No public unit price to model from. Why so few systems publish one →

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.

Performance specifications
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.	648 km/h Stronger than 42% of systems in its class
Cruise speed Sustained economical speed. Determines transit time to station.	474 km/h
Range Maximum distance: ferry range for aircraft, operational range for vehicles, maximum engagement distance for missiles. Higher means more standoff or persistence.	2,708 km Stronger than 46% of systems in its class
Endurance Time on station. Critical for UAVs and patrol platforms, higher means longer persistent coverage.	6 h

Physical

Dimensions, weight and crew.

Physical specifications
Length Overall length including gun/probe where applicable.	17.6 m
Wingspan Wingtip-to-wingtip span.	24.38 m
Height Overall height. Lower profile is harder to spot and hit for ground vehicles.	5.58 m
Empty weight Weight without fuel, ammunition or crew.	18,234 kg
Combat weight Fully loaded weight. Lighter eases transport and bridging limits; heavier often means more armor.	26,082 kg
Crew Personnel required to operate. Fewer reduces exposure; autoloaders trade a loader for mechanical complexity.	5

Propulsion

Engine, power and fuel.

Propulsion specifications
Engine Powerplant model and type.	Allison/Rolls-Royce T56-A-427A turboprop
Engines Number of engines. Twin-engine gives redundancy at higher cost.	2
Engine power Engine output power. Higher moves more weight faster.	5,100 hp
Propulsion type Turbofan, turboshaft, diesel, gas turbine, solid-fuel rocket, ramjet…	Turboprop

Sensors & avionics

Radar, sensor suite and datalinks.

Sensors & avionics specifications
Radar Primary radar. AESA (active electronically scanned array) is the current state of the art.	AN/APY-9 UHF-band AESA (rotodome)
