Malfunctioning Drone Hits US Navy Ship

A Navy guided missile cruiser hit by a malfunctioning drone during a training exercise on Saturday afternoon has returned to San Diego, where investigators will assess the damage and determine what went wrong. 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. She says investigators at Naval Base San Diego are assessing the damage and determining why the drone malfunctioned. About 300 crew members were aboard the ship at the time and the Navy could not say how the two sailors were injured. (More drones stories.)
