Pentagon lacks counter-drone procedure leading to incursions like at Langley, experts say

New reporting about over a dozen unidentified drones that were allowed to fly over Langley Air Force Base has prompted fresh calls for change to a threat that experts say will only become more prevalent. 

For more than two weeks in December 2023, the mystery drones traipsed into restricted airspace over the installation, home to key national security facilities and the F-22 Raptor stealth fighters. 

Experts say the incident is likely one of many that U.S. authorities are underprepared to tackle in an evolving threat environment. 

Lack of a standard protocol for such incursions left Langley officials unsure of what to do - other than allow the 20-foot-long drones to hover near their classified facilities. 

The Pentagon has said little about the incidents other than to confirm they occurred after a Wall Street Journal report this month. Whether it knows where the drones came from or what they were doing is unclear.

"I think they don't know," one congressional source familiar with defense operations told Fox News Digital.
