🇨🇳 Cai Hong-4B (CH-4B, reg. AD-34) MALE UAV with visible airborne (C?-Band), datalink antenna, gimballed EO-system and 4 pylons with no mounted carriage.

The 🇨🇳 CH-4B MALE UAV is the armed variant of the CH-4 (with the -A version being solely for reconnaissance purposes) developed by CAAA, which is part of CASC.

The drone changed dramatically in terms of aerodynamic design compared to it's predecessor, the CH-3; higher lift-to-drag and aspect ratios with V-shaped tail > lower fuel consumption and more endurance. Most of the body is made of alluminium alloy (with the exception of radome).

The drone has a retractable landing gear system equipped with a hydraulic shock adsorber (also used in the 🇮🇷 Gaza/Shahed-149 UAV) and is propelled by a 🇦🇹 Rotax 914 (114 hp/84 kW) 4-cylinder piston engine.

The drone has 4 composite pylons with the ability to carry 🇨🇳 AR-1 and 🇨🇳 FT-9 guided munitions; both of them spotted to be in use by 🇩🇿 Algeria.

Frames from the EO-system; the first in normal mode and the second in IR mode.

Specifications (🇨🇳 CH-4B for 🇩🇿 Algeria):
Length: 8.5 m
Wingspan: 18 m
MTOW: 1330 kg
Payload: 345 kg
Endurance: 35-40 hrs
Range: 250 km (within LOS), 2000 km (SATCOM)
Cruise altitude: 23,000 ft
Cruise speed: 180 km/h

They were presumably taken by the 🇨🇳 YY-12HD EO-system, specifications:
Diameter: 450 x 660 mm
Optical recognition range: +13 km
IR target recognition range: +18 km
Laser rangefinder (LRF): +15 km
Weight: ~60 kg
