Several drones repeatedly swarmed Navy destroyers off the California coast in July 2019, and it remains unclear who was behind the brazen nighttime flights, according to a report on the website The Drive, quoting ship logs.
As many as six drones flew around the warships at a time in often low-visibility conditions near Southern California's Channel Islands over a number of days, with the drones flashing lights and prompting security precautions onboard, according to the report.
The report was based mainly on Navy ship logs The Drive obtained through a Freedom of Information Act request, as well as publicly available ship tracking data. A documentary filmmaker, Dave Beaty, first uncovered some details about drone flights around the USS Kidd, a Navy destroyer, the report said.
The Navy did not respond to a request for comment.
