The U.S. Army Engineer Research and Development Center’s Research Vessel Martin, the first full-size, semi-autonomous craft of its kind in the U.S. Army Corps of Engineers (USACE), maneuvers near the Vicksburg, Mississippi, harbor April 1, 2021. A USACE civil works Navigation Systems Research Program project, the system gives surveyors the ability to conduct survey missions with a limited crew during emergencies — like the recent COVID-19 pandemic — or in post-disaster areas where it’s not safe to send a manned vessel.
