5G Cellular to 5G.MIL® Pilot Network Data Transfer Demonstrated

September 23, 2022

Lockheed Martin and AT&T securely and rapidly transferred UH-60M Black Hawk health and usage data through an AT&T 5G private cellular network and Lockheed Martin’s 5G.MIL® multi-site pilot network in a test conducted at Lockheed Martin’s Sikorsky headquarters in Stratford, Connecticut. The test demonstrated that wireless 5G technologies on the flight line can support accelerated maintenance operations and improved aircraft readiness to support service members. It also proved highly secure interoperability between the AT&T millimeter wave 5G private cellular network and the 5G.MIL pilot network.

The AT&T 5G millimeter wave private cellular network wirelessly transferred data to the 5G.MIL network through ground support equipment from the Black Hawk’s Integrated Vehicle Health Management System (IVHMS). The data was then routed to local Sikorsky networks for processing and distribution through the secure Lockheed Martin 5G.MIL pilot network to the Waterton, Colorado, 5G test range site. Currently, it takes Black Hawk crews about 30 minutes to remove the IVHMS data cartridge from the helicopter, transport it to an operations center and extract the data for analysis. Lockheed Martin used AT&T 5G private cellular technologies to reduce the time required to less than 5 minutes including cartridge removal, demonstrating the potential benefits in time and cost for military and commercial helicopter operations.

The IVHMS provides monitoring and diagnostic capabilities to ensure a more reliable aircraft. It monitors, captures, and evaluates detailed aircraft-generated data as a result of flight maneuvers. It also captures aircraft limit exceedances on airframe and dynamic components and monitors temperature and vibration of key components on the aircraft. It does this through hundreds of on-board sensors that report the status of the aircraft by monitoring the airframe, engines, and other dynamic components. Operators assess these thousands of data points to ensure the aircraft is safe, reliable and ready to fly.

Lockheed Martin and AT&T also are working with other leading companies in networking and defense to modernize and transform communications capabilities for defense purposes. Future demonstrations are expected to further enhance 5G wireless technology communications solutions for flight lines, aiming to continually shorten aircraft turnaround times to reduce costs and improve military operational readiness. These capabilities deployed at scale can support high-speed, secure-data transfer on both commercial and military flight lines.
