WASHINGTON — The U.S. Navy tested what one commander described as a combination of “unmanned and unmanned” sea and air capabilities in a Pacific Fleet demonstration known as Integrated Battle Problem 23.1. During the exercise, which began May 1 off the coast of California and runs through Friday, a V-BAT drone made by Shield AI was launched from a Leidos Seahawk medium displacement unmanned surface vessel, according to Cmdr. Jerry Daley , the leader of Unmanned Surface Vessel Division One. IBP
