BOYGA is a combat-proven rotary-wing UAV carrying 81mm mortar rounds, with VTOL, GNSS-denied autonomous navigation, 35-minute endurance, and day/night strike.

# STM Defense BOYGA – Rotary-Wing Munitions Dropping UAV System

The BOYGA is a combat-proven rotary-wing unmanned aerial vehicle developed by STM Defense for precision delivery of 81mm mortar ammunition. Designed for vertical takeoff and landing (VTOL), BOYGA combines low radar cross-section design with robust autonomy to perform day and night missions in contested environments.

Operational Capabilities

BOYGA integrates an ammunition release mechanism compatible with 81mm mortar rounds, enabling precision strikes guided via a Ground Control Station. Its advanced ballistic estimation algorithm and high-reliability fuze design support accurate delivery from high altitudes. The platform supports autonomous operations in GNSS-denied environments using KERKES technology and a CRPA antenna to resist GPS jamming.

Sensors and Navigation

Equipped with a 2-axis gimbal housing electro-optical and thermal imaging sensors, BOYGA provides HD (720p) video with 10× optical zoom for target acquisition and battle damage assessment. Precision landing sensors and emergency return-home functions increase mission safety and resilience.

Performance and Logistics

BOYGA offers approximately 35 minutes of flight endurance per mission load, a practical operational range up to 6.5 km, and a maximum takeoff weight near 17 kg. It is rated for temperatures from -20°C to +50°C and qualified to MIL-STD-810G for military environmental conditions. Quick installation (<1.5 minutes), mobile ground control, and compact dimensions make BOYGA easy to deploy and operate. It supports day and night operations seamlessly.
