Sea tests of a new unmanned surface vehicle (USV) for coastal defense have started off the coast on Singapore. When the tests are finished, the autonomous vessels will take over patrol operations in the Singapore Strait. The new ship, made by Singapore Technologies, is 16 meters long and five meters wide with a 30-ton displacement, maximum speed of 25 knots and capable of operating continuously for 36 hours. It will be equipped with sensors, weapons systems, strobe lights and sirens.   

The Janes website reports that the tests are being carried out off of a 16-kilometer area of Singapore's coast, mainly to test the operational functioning of the vessels in autonomous situations at sea. Singapore's Defence Ministry announced that the deployment of unmanned ships for defense of the coasts will allow large manned ships of the Navy to carry out operations far from the coast.
