STM’s autonomous unmanned underwater vehicle, STM NETA 300, successfully captured images of a sunken tank

STM Savunma Teknolojileri Mühendislik ve Ticaret A.Ş., one of Türkiye’s leading defence engineering
companies, continues to demonstrate its capabilities in autonomous underwater technologies across
diverse operational environments. STM NETA 300, the first member of STM’s Autonomous Unmanned
Underwater Vehicle (AUV) family, recently conducted an autonomous underwater reconnaissance
mission near Güvercin Island, off the coast of Kaş, Antalya, Türkiye.
Operating in an area of the Mediterranean known for its rich marine biodiversity and underwater
wrecks, STM NETA 300 conducted search and rescue, wreck detection and identification activities,
surveying the underwater environment using its advanced sonar systems and high-resolution imaging
capabilities. During the mission, the vehicle successfully captured images of a sunken tank,
demonstrating its autonomous reconnaissance, underwater object detection and imaging capabilities
under real-world maritime conditions.
The tank captured in images by STM NETA 300 had previously served in the Turkish Armed Forces
and was deliberately submerged off Güvercin Island in Kaş in 2017, following the end of its service
life, to promote diving tourism and create an artificial reef.
Güleryüz: Advancing the Future of Autonomous Maritime Operations
Highlighting the growing importance of unmanned maritime systems in future naval operations, Özgür
Güleryüz, General Manager of STM, stated:
“The maritime security landscape is undergoing a significant transformation driven by advances in
autonomous technologies. At STM, we combine our extensive naval engineering expertise with
artificial intelligence and autonomy to develop next-generation maritime systems. The recent
autonomous reconnaissance mission conducted by STM NETA 300 in the Mediterranean demonstrates
the capabilities of our underwater technologies in real-world operating conditions. Developed within a
short timeframe, STM NETA 300 represents the first platform in our expanding family of unmanned
maritime systems.
Building on this foundation, we have expanded our portfolio with TENGİZ, our Extra Large Unmanned
Undersea Vehicle (XLUUV), and STM YAKTU, our kamikaze unmanned surface vehicle, offering
solutions for a wide range of underwater and surface missions. We remain committed to advancing
autonomous maritime technologies that will shape future naval operations and enhance the
operational capabilities of the Turkish Navy and our international partners.”
STM NETA 300 Demonstrates Autonomous Mine Detection Capabilities During Naval
Exercise
STM NETA 300 previously demonstrated its operational capabilities during the TURNAs-2026 naval
exercise held in Antalya in October, participating in advance force operations. Equipped with advanced
sonar systems and high-resolution sensors, the vehicle autonomously detected and identified mines
and mine-like underwater threats along the transit route, contributing to the safe passage of main
naval units and successfully completing its mission. During the exercise, STM NETA 300 also
conducted underwater scanning and detection activities as part of seabed warfare operations,
supporting critical infrastructure security and underwater pipeline inspections. These missions further
demonstrated the vehicle’s capabilities in supporting Mine Countermeasures (MCM) operations and
enhancing the safety of naval operations.
