STM reports NETA 300 mine-detection mission at TURNAs-2026

STM reported on 25 October that its NETA 300 light autonomous underwater vehicle took part in an advance-force operation during Türkiye's TURNAs-2026 unmanned maritime systems exercise. The company says the vehicle used onboard sonar and other sensors to detect and identify mines and mine-like objects along a transit route, helping the main naval force assess navigation safety. This is a supplier account of an exercise mission; no independent scoring report was provided.

What was demonstrated

The reported task combined autonomous underwater survey with the detection and identification stages of a mine-countermeasures operation. STM did not publish the number of objects, false-alarm rate, water depth, survey area, navigation error, mission duration or environmental conditions. It did not say NETA 300 neutralised a mine. The exercise therefore supports a narrower conclusion than full, operational mine-clearance capability.

Programme status

STM's existing product information describes a modular, two-person portable AUV with optional sensor configurations. It has previously announced a first domestic sales contract and says the Turkish Navy will use NETA 300. A contract and a successful exercise sortie are separate milestones; this release does not identify a delivery, service acceptance date or routine deployment. The existing NETA 300 profile and underwater-systems guide place the event in the wider mine-countermeasures landscape. Further evidence should cover repeatable detection performance, human review of classifications and an accepted naval configuration.
