South Korea's LIG Nex1 announced on 15 December that it has completed sea trials of its Haegum-2 (Sea Sword 2) unmanned surface vehicle (USV).
The company said development work on the Sea Sword 2 was carried out under a three-year programme supported by the Defense Acquisition Program Administration and the country's Ministry of Trade, Industry, and Energy.
It added that the Sea Sword 2 was put through a seaworthiness trial in waters near Namhae Island on the southern coast, proving its ability to operate without supervisory personnel aboard in conditions of up to Sea State 4.

It is equipped with various sensing and mapping technologies and an automated launch and recovery system. It features a displacement of 11 tonnes and has an overall length of 12 m and a 3.5 m beam.
