A U.S. Marine Corps Hero-400 loitering munition drone is staged before flight on San Clemente Island, California, May 25, 2022. The Hero-400 is a loitering munition that the United States Marine Corps and other Department of Defense entities are beginning to incorporate into specific mission sets. This initial training flight develops the unmanned aerial systems pilots’ confidence and abilities to be able to operate the Hero-400 in any clime and place, and enabling 3rd MAW to remain a more lethal and ready force.
