ALPAGU-B Fixed-Wing Loitering Munition Showcased at SAHA EXPO
STM, advancing its breakthroughs in autonomous systems, has debuted ALPAGU-B, the newest member of its fixed-wing loitering munition family, at SAHA 2026. As a larger and longer-range version of the ALPAGU, ALPAGU-B elevates 'surgical strike' capabilities to a strategic level on the modern battlefield with its AI-powered target tracking and high-explosive impact.
STM Savunma Teknolojileri Mühendislik ve Ticaret A.Ş., a leader in developing cutting-edge technologies for naval platforms and unmanned systems within the Turkish defense industry, is taking its ambition in the tactical loitering munition segment to the next level. Following the success of the man-portable ALPAGU system, the newly developed ALPAGU-B has made its global debut at SAHA 2026.
Next-Generation Strike Capability Across All Ranges
Highlighting the operational flexibility of ALPAGU-B, STM General Manager Özgür Güleryüz stated:
"We are bridging the critical gap between our 10-km range ALPAGU and our Long-Range Loitering Munition systems with ALPAGU-B. With this new move, we are completing our fully autonomous strike power at every level, from the tactical field to deep operational theaters. By merging the experience gained from ALPAGU with field feedback, we have transformed it into ALPAGU-B, a larger and more lethal platform. Despite weighing under 20 kg, this system carries a 4 kg warhead, serving as a critical force multiplier especially for our special forces and infantry units. Field testing has already commenced. Capable of neutralizing high-value targets without entering high-risk areas, ALPAGU-B once again proves STM’s engineering prowess through its indigenous software, advanced electronic munition safety, and AI-based guidance."
Precision Lethality Beyond the Line of Sight
ALPAGU-B is equipped with next-generation AI-powered image processing technology. The system autonomously detects and tracks both moving and stationary targets, neutralizing them through a high-precision dive in the terminal phase. With its low radar cross-section (RCS) design and minimal acoustic signature, ALPAGU-B is specifically engineered to evade radar and air defense systems.
Equipped with MIL-STD 331-compliant advanced electronic ammunition safety and fuzing systems, ALPAGU-B prioritizes user safety at the highest level. Featuring mission abort and self-destruct modes to ensure that full operational control remains with the user at all times, the system provides uninterrupted day-and-night mission capability via its EO/IR (Electro-Optical/Infrared) camera. Developed with indigenous hardware and embedded software architecture, the platform allows for operation in all terrain conditions.
