U.S. defense contractor L3Harris Technologies said it has completed more than 70% of a project to modernize the communications infrastructure supporting the National Airspace System, as the Federal Aviation Administration (FAA) investigates a telecommunications outage that prompted a nationwide flight halt on Nov. 13.
In a statement shared on social media, L3Harris said it has been working closely with the FAA and telecommunications partners to replace outdated copper cables with a fiber-optic system, prioritizing safety and reliability.
The company, which is responsible for modernizing the FAA's communications infrastructure, said more than 70% of the planned conversion has been completed.
L3Harris said it is assisting the FAA in investigating the circumstances that led to the Nov. 13 ground stop, which disrupted air travel across the U.S.
The company emphasized that it takes the incident and its impact on passengers, airlines and air traffic operations seriously.
The FAA announced on Nov. 13 that a temporary telecommunications outage had affected air traffic control centers, prompting authorities to suspend flights at airports nationwide as a precaution.
Flights across the U.S. were halted for more than four hours before operations returned to normal following the telecommunications disruption.
Despite the resumption of flight operations, delays and cancellations continue to affect air travel nationwide.
L3Harris said it remains engaged with the FAA in the investigation while continuing its communications modernization project.
