There have been “multiple” cases of drones entering the airspace of a Navy weapons station in New Jersey, officials there said Friday, as concerns continue to grow over widespread drone sightings in the region.

Naval Weapons Station Earle, located in Colts Neck, New Jersey, said it was “aware” of the sightings in the area and “continues to work closely with federal and state authorities to ensure the safety of our personnel and operations.” to ensure”.

“While no direct threats to the installation have been identified, we can confirm multiple instances where unidentified drones have entered the airspace over Naval Weapons Station Earle,” Naval Station Public Affairs Officer Bill Addison said in a statement to ABC News . “The base remains prepared to respond to potential risks by leveraging robust security measures and advanced detection capabilities.”

The base did not say when the incidents occurred.

Residents in northern New Jersey — particularly in Morris and Somerset counties — have shared many videos and stories since mid-November about drones larger than those used by hobbyists that have been overheard at night. Colts Neck is located in Monmouth County, in the eastern part of the state.

Sen. Andy Kim, who took office just this week, spent Thursday night in Hunterdon County, which borders Somerset, where he said he saw dozens of drones in two hours.

“The people deserve answers,” Kim told reporters after his visit to the county. “We don’t need conspiracy theories or conjecture, we need reassurance that the people responsible for our security know about the problem, and a line of communication so that people feel their government is taking the matter seriously.”

He reiterated his calls for a federal investigation by the FBI and Department of Homeland Security. Kim was one of four senators in New York and New Jersey – along with Democratic senators Chuck Schumer, Kirsten Gillibrand and Cory Booker – who wrote a letter to federal officials on Wednesday calling for action.

“We write with urgent concern about the unmanned aerial system (UAS) activity that has affected communities across New York and New Jersey in recent days,” the letter said.

Although the letter did not specifically mention Naval Weapons Station Earle, it included a note that the drones were observed near “critical infrastructure and sensitive locations, including reservoirs and military facilities.”

The White House downplayed some of residents’ concerns in a news conference Thursday. National security communications adviser John Kirby said “many” of the reported drone sightings appeared to be legally operating manned aircraft.

“We currently have no evidence that the reported drone sightings pose a threat to national security or public safety or have any foreign connection,” Kirby added. “The Department of Homeland Security and the FBI are investigating these sightings and working closely with state and local law enforcement to provide resources to better understand their origins using a variety of detection methods.”

After seeing the drones with his own eyes late Thursday, Kim said the comments weren’t necessarily reassuring to residents.

“It’s hard for people to feel safe when unexplained drones are flying overhead and they’re not getting the answers they need from federal investigations,” Kim said. “This has been going on for weeks and I’m as frustrated as everyone else at not getting any more information and details. So I came out to see for myself and I’m grateful to the local police for showing me around.”
