STM unveiled two of its latest innovations at IDEF 2025: the BOYGA-B rotary-wing UAV, capable of carrying multiple munitions, and the TUNGA Smart Munition System. IDEF, the International Defense Industry Fair, is a globally recognized trade fair in the defense industry, ths year hosted by Türkiye in Istanbul July 22-27.

The BOYGA-B Ammunition Drop UAV is engineered for tactical missions such as reconnaissance, surveillance, target detection and precision munition deployment. The system can carry smart munitions as well as two 81 mm UAV munitions.

The TUNGA Smart Munition System, developed for anti-personnel missions, has a modular design, image-based or GNSS-based guidance, and proximity-fuze detonation capability. Both new systems are designed to meet the evolving needs of modern combat environments.

BOYGA-B Ammunition Drop UAV

BOYGA-B is a high-precision rotary-wing UAV designed for reconnaissance, surveillance, target engagement and precision munition deployment in tactical operations. It can operate in GNSS-denied or jammed environments with its CRPA antenna and KERKES integration. The system can carry up to 8 kg of munitions and precisely release them onto targets using its integrated drop mechanism.

Key Features

  • GNSS-denied operation via CRPA and KERKES
  • Flight time: 35 minutes
  • Range: Minimum 5 km
  • Operable by a single soldier
  • Target detection and tracking
  • Real-time EO/IR image transmission
  • Autonomous munition release and mission abort

Payload Options

  • 2× 81 mm UAV Munitions
  • 1× TUNGA Smart Munition
  • 1× Kargu FPV Drone

TUNGA Smart Munition System

TUNGA is a glide-type guided munition developed by STM for anti-personnel missions. Equipped with a 1750 g warhead, TUNGA can be precisely guided to its target using EO/thermal imaging and onboard image processing. It offers safe operation with self-destruct functions and can be deployed from BOYGA-B or other compatible platforms.

Key Features:

  • GNSS or image-based guidance
  • Self-destruct options
  • Modular design for different mission profiles
  • Low visibility with EO/thermal imaging
  • Proximity-fuse detonation

Technical Specifications

  • Length: 540 mm
  • Warhead: 1750 g
  • Endurance: 30 minutes
  • Operational altitude: 300–800 m
