Belarus’ State Authority for Military Industry has introduced the Quad-M unmanned aerial system (UAS), a major upgrade of the earlier Quad-1400 platform. The system supports pre-programmed coordinate-based release of unguided munitions. It is intended to engage personnel and light vehicles.
Quad-M uses a multirotor vertical takeoff and landing (VTOL) configuration. Maximum takeoff weight is approximately 79 lb (36 kg). The aircraft can carry up to three PTAB-2.5 anti-armor submunitions or alternative ordnance with a combined payload of up to 22 lb (10 kg).
The platform can hover over the target area to refine aimpoint parameters prior to release. This profile enables controlled, short-range employment of unguided munitions.
Mission Systems
The primary upgrade centers on a new electro-optical (EO) payload. The UAV carries a three-axis gyro-stabilized turret integrating a daylight zoom camera, an infrared (IR) sensor, and a laser rangefinder.
This configuration enables day-night target detection, range measurement, and generation of targeting data for ballistic munitions.
Communications and Performance
Control is provided through a digital radio link. Effective control range is stated at up to 3.1 miles (5 km), extendable to 6.2 miles (10 km) with a relay node. Maximum speed reaches 45 mph (72 km/h). Endurance is approximately 25 minutes. Operational altitude is listed at up to 1,640 ft (500 m) and above.
Positioning Within the Emerging Heavy Multirotor Segment
A distinct class of heavy multirotor bomb-drop UAVs has emerged during the war in Ukraine. These platforms differ from high-speed FPV strike drones and from light quadcopters adapted for improvised grenade release.
| Parameter | “Quad-M” (Belarus) | “Berdysh” / “Zanoza” / “Provod” (Russia) | “Baba-Yaga” / “Vampire” (Ukraine) |
|---|---|---|---|
| Payload capacity | estimated up to 8–10 kg | 4.5–20+ kg (depending on variant) | up to 15 kg |
| Operational range | up to 5 km; up to 10 km with relay | 12–30 km (including fiber-optic control) | ~6–10 km |
| Endurance | up to 25 minutes | 15–30 minutes | 20–37 minutes |
| Control method | radio data link | radio / fiber-optic control (Zanoza, Provod) | radio data link |
| Surveillance and targeting system | 3-axis gyro-stabilized EO module with thermal imager and laser rangefinder | FPV cameras; stabilization and rangefinder not standard | FPV cameras, limited stabilization |
| Capability against fortified targets | limited | yes (82/120 mm mortar rounds, HE charges, RPG munitions) | limited |
| Primary tactical role | controlled multi-munition release from hover | fortification attack, deep strike, logistics support | localized strikes on positions and troop concentrations |

Typical parameters for the segment include payload capacity above 9–11 lb (4–5 kg), operational range of 6–18 miles (10–30 km), and the ability to engage fortified positions.
Rather than competing with long-range heavy platforms, Quad-M focuses on short-range precision strike missions. Unlike Russian heavy platforms such as Berdysh, Zanoza, and Provod—which operate at extended ranges, carry heavier ordnance, and in some cases use fiber-optic control links to mitigate electronic warfare—Quad-M prioritizes integrated targeting and controlled release at limited standoff distances.
Ukrainian systems such as Baba Yaga and Vampire generally offer comparable payload capacity but rely primarily on FPV guidance with limited stabilization and high operator dependency.
Quad-M is not intended to compete with long-range heavy strike systems. Its tactical role centers on precision engagement within constrained depth, where hover capability, stabilized EO targeting, and operator-controlled gravity release define mission effectiveness.
