Two sailors were treated for minor burns after the USS Chancellorsville was struck by the unmanned aircraft during radar testing off Point Mugu in southern California. A Navy official says the the drone—which was 13 feet long, 1 foot in diameter, and had a wingspan of nearly 6 feet —hit the ship's left side.

About 300 crew members were aboard the ship at the time and the Navy could not say how the two sailors were injured.
