L3Harris has completed more than 70% of a planned conversion of the National Airspace System's communications infrastructure from legacy copper wires to a fiber optic system. This modernization project, conducted in coordination with the Federal Aviation Administration (FAA), is under scrutiny following a nationwide ground stop of air travel on November 13.
Infrastructure Modernization Efforts
L3Harris is a primary contractor involved in modernizing the communications infrastructure that supports the National Airspace System. Working alongside the FAA and various telecommunications partners, the company is replacing outdated copper wiring with a more resilient fiber optic network.

The transition is a significant undertaking designed to enhance the reliability of air traffic communications. By moving to fiber optics, the system aims to provide a more stable foundation for the data required to manage safe flight paths and ground operations.
Response to the November 13 Ground Stop
Following the nationwide ground stop on November 13, L3Harris issued a statement emphasizing that safety and reliability remain its highest priorities. The company is actively cooperating with the FAA to identify the conditions that triggered the disruption.
The ground stop impacted travelers, airlines, and air traffic operations across the country. L3Harris stated it takes the impact of this event seriously as it works with regulators to understand the underlying technical failures.
Ongoing Transition and Uncertainties
While the conversion to fiber optics is more than 70% complete, the remaining 30% of the infrastructure remains in a transitional state. The interplay between the legacy systems and the new fiber network presents a complex environment during the rollout.
The exact technical conditions that led to the November 13 ground stop have not yet been publicly detailed. The investigation is ongoing to determine whether the issue was a result of the legacy hardware, the new fiber implementation, or a failure in the integration between the two.
