In 2020, the South Korean firm unveiled a prototype of its unmanned surface vehicle (USV) Sea Sword (Haegum), which was developed and designed for coastal defense.

This Sea Sword Multi-purpose USV enables mapping and fusion of detected data, and creation of complex data through the unmanned surface & underwater platforms even in maritime environment difficult for human to approach. For the military application, underwater, where submersibles can infiltrate, surveillance and mine detection missions are feasible in the West Sea of the North Korea.

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.
