L3Harris leads the industry as the premier provider of data links and communications systems for the world’s most advanced airspaces, weapon systems and Command and Control platforms. We also provide safety-critical and highly-secure managed infrastructure services for mission-critical communications, air traffic surveillance, and information management systems to deliver connectivity across government enterprise networks.
Resilient Communications and Networks
Cutting-edge communications, data link and information management technologies critical to safe skies and the national security of the U.S. and allied defenses.
'Resilient in a degraded environment' – in other words: maintaining communications in remote and austere locations – is one of six JADC2 guiding principles. However, despite the near-universal acknowledgement throughout the U.S. government and defense industrial base of the criticality of resilient communications, industry remains without a clear definition or standard for the term. This lack of clarity poses significant risk of slowing progress toward realizing JADC2.

L3Harris plays a critical role in worldwide air traffic management by providing safety-critical managed enterprise infrastructure services and delivering communications, information management and airspace surveillance solutions. Our networks provide the security, reliability and availability for safe manned and unmanned aircraft operations, and enable the safe and efficient modernization for the future.
For three decades, L3Harris has delivered increasingly advanced communications technologies; developed the largest dedicated communications and operations network infrastructure for the Federal Aviation Administration and international customers; and instituted air-to-ground and inflight data communications. L3Harris also designed, developed, installed and operates the automatic dependent surveillance-broadcast (ADS-B) ground network for U.S. air traffic surveillance.
