New Power for the Tactical Field: BOYGA-B and TUNGA Make Their Debut at IDEF
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.
STM, a leading defense technology company known for its innovative and indigenous solutions, introduced two new game-changing products at the IDEF 2025 International Defence Industry Fair, held in Istanbul between July 22–27. Making their first public appearance, the BOYGA-B Ammunition Drop UAV and the TUNGA Smart Munition System are designed to meet the evolving needs of modern combat environments.
BOYGA-B 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. TUNGA, developed for anti-personnel missions, stands out with its modular design, image-based or GNSS-based guidance, and proximity-fuze detonation capability.
“We Are Elevating Our UAV Capabilities with BOYGA-B and TUNGA”
STM General Manager Özgür Güleryüz emphasized that STM continues to expand its family of tactical UAVs based on the evolving needs of the field. He stated:
“With the power of Turkish engineering, we are introducing new capabilities to the tactical battlefield. BOYGA-B, the enhanced version of our munition-drop UAV BOYGA, brings a flexible platform capable of carrying and deploying different types of munitions. This makes it an effective solution against a wide range of threats. TUNGA, on the other hand, leverages image processing technologies to deliver pinpoint strikes via tactical UAVs. Both systems have successfully completed field tests and are ready for deployment. With BOYGA-B and the TUNGA Smart Munition System, STM is taking its UAV expertise to the next level. We will continue to deliver innovative, indigenous solutions for our Armed Forces and our allied nations.”
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.
