Availability & export
Italian export-licensed
UAMA authorisation; standard EU/Wassenaar controls.
Channel: Direct commercial / G2G
Fielded & proven
Established · 9 operators
In service since 1999. Status: active · ~220 built.
Lifecycle cost (est.)
$150M – $210M
Acquisition is only ~30% of lifecycle cost, operating & support dominate over ~30 yrs. Rough 2.5–3.5× the unit price. How we estimate this →
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. | 309 km/h |
|---|---|
| Range Maximum distance: ferry range for aircraft, operational range for vehicles, maximum engagement distance for missiles. Higher means more standoff or persistence. | 1,389 km |
| Service ceiling Maximum operating altitude. Higher gives energy advantage and sensor horizon. | 4,575 m |
Physical
Dimensions, weight and crew.
| Length Overall length including gun/probe where applicable. | 22.8 m |
|---|---|
| Height Overall height. Lower profile is harder to spot and hit for ground vehicles. | 6.62 m |
| Empty weight Weight without fuel, ammunition or crew. | 10,500 kg |
| Combat weight Fully loaded weight. Lighter eases transport and bridging limits; heavier often means more armor. | 15,600 kg |
| Crew Personnel required to operate. Fewer reduces exposure; autoloaders trade a loader for mechanical complexity. | 4 |
| Troop capacity Number of embarked troops/passengers (IFV, APC, transport). Higher carries more. | 30 |
Propulsion
Engine, power and fuel.
| Engine Powerplant model and type. | 3× Rolls-Royce Turbomeca RTM322 turboshaft |
|---|---|
| Engines Number of engines. Twin-engine gives redundancy at higher cost. | 3 |
| Propulsion type Turbofan, turboshaft, diesel, gas turbine, solid-fuel rocket, ramjet… | Turboshaft |
Sensors & avionics
Radar, sensor suite and datalinks.
| Radar Primary radar. AESA (active electronically scanned array) is the current state of the art. | Search-water 2000 surveillance radar |
|---|---|
| Sensors IRST, EO/IR turrets, laser designators, sniper pods, thermal sights. | dipping sonar, sonobuoy processor, FLIR |
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. | $60,000,000 |
|---|---|
| Units built Total production run. Higher means proven manufacturing, mature logistics and spares availability. | 220 |
| Operator countries Number of countries operating the system. More operators means broader support ecosystem. | 9 |
