Transportation Secretary Sean Duffy criticized the U.S. air traffic system for being outdated and pushed the Senate to approve the Big Beautiful Bill, which allocates $12.5 billion for system upgrades.

During a briefing at the Transportation Department, Duffy shared updates about Newark International Airport in New Jersey, where old infrastructure and insufficient staffing have already caused radar and telecom failures.

“Our air traffic control system is old and outdated, with equipment ranging from 25 to 40 years in some areas,” Duffy stated. “It urgently needs a complete overhaul, and Congress must take action.”

Additionally, only 16 of the 27 people at Philadelphia TRACON, which controls Newark’s airspace, are working due to trauma leave and medical leave, Duffy said. Five of the 27 are supervisors.

He said that 16 controllers are in training and will be deployed over the coming months.

“We normally run 50–54 departures an hour at Newark, that’s now down to 28 an hour due to staffing,” Duffy said. “When the runway reopens June 15, we’ll bump that up to 34 an hour and reassess again in October once more controllers are certified.”

There is currently a shortage of 3,000 air traffic controllers across the U.S., Duffy said, but he insisted the system is safe.
