For the second time in just a week an Iranian drone flew ‘too close’ to a US Navy F-18 Hornet and followed the USS Nimitz aircraft carrier at night. The US Navy stated that these activities are putting their pilots lives at risk.

The Iranian Sadegh drone flew without any warning lights during the encounter Sunday night with the USS Nimitz, said Lt. Ian McConnaughey, a spokesman for the Bahrain-based 5th Fleet.

The drone did not respond to repeated calls over the radio and came within 1,000 feet (300 meters) of U.S. fighters, he said.
