The temporary flight restrictions, which are set to last until Jan. 17, have been implemented beginning Wednesday in the following locations: Hamilton, Bridgewater, Cedar Grove, North Brunswick, Metuchen, Evesham, Camden, Gloucester City, Westampton, South Brunswick, Edison, Branchburg, Sewaren, Jersey City, Harrison, Elizabeth, Bayonne, Winslow, Burlington, Clifton, Hancocks Bridge and Kearny.
The restrictions say no uncrewed aircraft systems can operate within a nautical miles of the airspace specified in each Notice to Airmen, or NOTAM, including from the ground up to 400 feet. Recreational drones are allowed to operate up to 400 feet, under FAA rules.
The previously issued temporary flight restrictions for Bedminster and Picatinny Arsenal remain in place.
The government may use "deadly force" against the drones if they pose an "imminent security threat," the NOTAM said.
