Naval SystemsExplosive unmanned surface vesselUncrewed surface vesselExplosive unmanned surface vessels used by the Houthis are small remote or semi-remote maritime attack craft adapted for one-way strikes against ships in the Red Sea and Gulf of Aden. In the current Yemen conflict they broaden Houthi sea denial beyond missiles and aerial drones, with confirmed attacks against commercial shipping and repeated launches from Yemen's Red Sea coast.
