China China Aerospace Science and Technology Corporation (CASC)
CH-4 (Caihong-4)
A medium-altitude long-endurance armed reconnaissance drone roughly comparable to the MQ-1 Predator, exported widely across the Middle East, Africa and Asia at a lower cost than Western systems. One of the most widely proliferated Chinese armed UAVs.

Availability & export
Chinese state channel
State export agencies (NORINCO/CATIC); limited availability to Western-aligned states.
Channel: State export agency
Fielded & proven
Established · 10 operators
In service since 2014. Status: active.
Lifecycle cost (est.)
$10M – $14M
Acquisition is only ~30% of lifecycle cost — operating & support dominate over ~20 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.
- 235 km/h Stronger than 59% of UAVs
- Cruise speed
Sustained economical speed. Determines transit time to station.
- 180 km/h Stronger than 65% of UAVs
- Range
Maximum distance: ferry range for aircraft, operational range for vehicles, maximum engagement distance for missiles. Higher means more standoff or persistence.
- 3,500 km Stronger than 83% of UAVs
- Service ceiling
Maximum operating altitude. Higher gives energy advantage and sensor horizon.
- 7,000 m Stronger than 48% of UAVs
- Endurance
Time on station. Critical for UAVs and patrol platforms — higher means longer persistent coverage.
- 30 h Stronger than 85% of UAVs
Firepower
Armament, payload and guidance.
- Hardpoints
External stations for weapons and pods. More means bigger and more flexible loadouts.
- 6 Stronger than 68% of UAVs
- Weapons payload
Maximum ordnance weight the platform can carry. Higher means more strike capacity per sortie.
- 345 kg Stronger than 53% of UAVs
Physical
Dimensions, weight and crew.
- Length
Overall length including gun/probe where applicable.
- 8.5 m
- Wingspan
Wingtip-to-wingtip span.
- 18 m
- Empty weight
Weight without fuel, ammunition or crew.
- 850 kg
- Combat weight
Fully loaded weight. Lighter eases transport and bridging limits; heavier often means more armor.
- 1,330 kg
- Crew
Personnel required to operate. Fewer reduces exposure; autoloaders trade a loader for mechanical complexity.
- 0
Propulsion
Engine, power and fuel.
- Engine
Powerplant model and type.
- Piston engine
- Propulsion type
Turbofan, turboshaft, diesel, gas turbine, solid-fuel rocket, ramjet…
- Piston, pusher propeller
Sensors & avionics
Radar, sensor suite and datalinks.
- Sensors
IRST, EO/IR turrets, laser designators, sniper pods, thermal sights.
- Electro-optical/infrared targeting turret
- Datalink
Network connectivity: Link 16, MADL, national datalinks. Enables cooperative engagement.
- LOS datalink, SATCOM
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.
- $4,000,000 Stronger than 59% of UAVs
- Operator countries
Number of countries operating the system. More operators means broader support ecosystem.
- 10 Stronger than 79% of UAVs
