STM’s NETA 300, the first of the NETA Unmanned Underwater Vehicle (UUV) family, has been shown diving down during the sea trials in a video shared on X.
NETA 300 UUV being developed for underwater surveillance against various threats, including mines, was shown on its sea trials for the first time in a social media post by STM.
The NETA family of UUVs were revealed during the SAHA EXPO 2024 exhibition as two variants: the NETA 300 and the larger NETA 1000.

NETA 300 can carry side-scan and gap-filling sonars to detect underwater mines and operate for 24 hours. The first deployment of NETA 300 is expected on the Turkish Navy’s minehunting ships as remote sensors.
NETA 1000, as the larger variant, will have a longer endurance at 32 to 55 hours and carry a larger variety of sensors. Due to higher-end sensor capabilities, NETA 1000 might be used as a remote sensor in Anti-Submarine Warfare (ASW) missions in addition to mine detection.
During SAHA EXPO 2024, it was also stated that even larger UUVs will be developed for other types of missions. This signals that STM will not stop at medium-class UUVs but will move towards large or extra-large types with far longer endurance and possibly light armaments.
