Visão geral
18 m multi-mission USV from ST Engineering, chosen for Singapore's mine countermeasures fleet.
The Swift 18m is an 18-metre uncrewed vessel from Singapore's ST Engineering that carries a 20-foot container's worth of mission equipment. It can reach 35 knots, run for three days and berth or hold position on its own, with operators supervising from shore or a mothership. Mission kits include towed sonar and expendable mine-disposal drones, firefighting and search and rescue. The Republic of Singapore Navy chose it for its mine countermeasures modernisation, with French firm Exail supplying navigation and sonar.
