Who Is L3Harris? Contractor Under Scrutiny Over FAA Shutdown

L3Harris Technologies, a major U.S. defense and communications contractor, is under investigation following a 4-hour nationwide ground stop of the Federal Aviation Administration's (FAA) flights. The incident occurred after a router involved in the company's upgrade of copper wire to fiber-optic cable generated an overwhelming number of connection requests, causing parts of the FAA network to fail.

Transportation Secretary Sean Duffy stated that investigators are still working to determine the exact cause of the failure, with no final determination made at this time. L3Harris has emphasized its support for the ongoing investigation and expressed concern over the nationwide disruption to travelers, airlines, and air traffic operations.

The company, formed in 2019 through the merger of Harris Corporation and L3 Technologies, employs around 45,000 people and generates billions of dollars in contracts for military communications, intelligence systems, surveillance technology, space programs, and aviation infrastructure. The fault in the FAA's communications network triggered the largest nationwide ground stop since the 9/11 terrorist attacks, with tens of thousands of flights delayed or canceled worldwide.

L3Harris has been responsible for key portions of the FAA Telecommunications Infrastructure for over two decades, with the network supporting approximately 45,000 daily flights and linking over 4,400 FAA facilities. The company has completed more than 70% of the upgrade from legacy copper wires to a fiber-optic system, striving to maintain a 99.99971% network reliability.
