Fassmer Defence | GREYSHARK AUV – Port & Pipeline Security

Autonomous underwater strength

The AUV for the next generation of underwater defense

GREYSHARK™ is a state-of-the-art, fully autonomous underwater vehicle (AUV) designed for long-endurance, multi-mission operations in complex maritime environments. With its extreme range, high speed, and superior sensor capabilities, GREYSHARK™ sets new standards in reconnaissance, surveillance, and critical infrastructure protection.

GREYSHARK™

Long-range AUV for protection and reconnaissance

With a range of over 1,000 nautical miles, an economical cruising speed of around 10 knots, and high-precision navigation, the GREYSHARK™ is ideal for long-distance pipeline protection, port security, or covert reconnaissance.
