SAN DIEGO (AP) A U.S. Navy official says a malfunctioning drone left a hole in a Navy guided missile cruiser and caused internal damage after it struck the ship during a weekend exercise off the California coast.
Lt. Rick Chernitzer says officials examined the USS Chancellorsville on Monday, aday after it pulled into San Diego.
The ship was tracking the unmanned aircraft during radar testing Saturday when the drone struck it.
Two sailors were treated for minor burns.
Officials have declined to comment further while the cause is being investigated.
The aerial drone was a BQM-74 series, manufactured by Aerospace giant Northrop Grumman Corp. According to the company website, the drones can simulate enemy missiles or airplanes.
