It is also equipped with state-of-the-art detection equipment and can perform coastal surveillance, marine disaster response, and surveillance missions in a dangerous coastal environment.
The Sea Sword Multi-purpose USVs can be deployed to near-enemy sea areas for surveillance, reconnaissance and underwater search to contribute and conduct sea search operation. It can be also used to survey illegal fishing, life-saving operations, oceanographic investigation, and other maritime operations.
For combat operations, the Sea Sword USV can be fitted with a remotely operated weapon station that can be armed with a 12.7mm heavy machine gun. The rear deck can be also fitted with a two-axis eight-cell guided-rocket launcher for 70 mm Poniard rockets.
The Sea Sword USV has a weight of 11 tones and an overall length of 12 m, a 3.5 m beam, and is based on a low RCS (radar cross-section) monohull made of fiber-reinforced plastic. It is powered by two diesel engines driving two Kamewa waterjets to a speed of more than 35 knots, or a maximum range of 180 n miles at a cruising speed of 20 knots.
