U.S. Marines test new F-35 ground comms tactics at WTI

U.S. Marines from Marine Fighter Attack Squadron 251 demonstrated improved communication and digital interoperability capabilities for F-35 and other fixed-wing aircraft ground operations during Weapons and Tactics Instructors course 2-26 at Marine Aviation Weapons and Tactics Squadron One, Marine Corps Air Station Yuma, Arizona, on 13 April.

The effort centred on the Marine Corps’ Digital Interoperability kit, a suite of hardware, software, and networked devices designed to connect Marines operating across otherwise incompatible systems. VMFA-251 personnel used specialised DI hardware to securely relay Link 16 data to ground-based tablets, extending the secure tactical data link, which carries real-time information on aircraft position, fuel status, and mission data, directly to flight line crews for the first time in this configuration.

Chief Warrant Officer 2 Jory D. Reed, an aviation ordnance officer with VMFA-251, identified the gaps that prompted the work. “A lot of this came from observing how Marines execute the mission and identifying where time and effort could be streamlined,” Reed said. “The goal was to make those processes both more efficient and repeatable.”

Chief Warrant Officer 2 Eladio Vega, an avionics officer with the squadron, led the technical integration and translation of those capabilities into operational practice. “The DI kit consolidates data from multiple communication systems onto a single platform allowing a cohesive flow of information between different military assets,” he said. “Using the MAGTAB, Marines can view aircraft location, fuel states, and remaining ordnance in real time, giving ground crews advance knowledge of aircraft needs before landing, which is something we couldn’t do before.”

Reed described the practical effect on turnaround operations. “Now we can see what assets the aircraft has expended and what it will require before it even touches down. That gives us the ability to respond faster and more accurately, preparing exactly what’s needed ahead of time instead of moving excess ordnance and equipment once the aircraft arrives.”

VMFA-251 also evaluated a direct communication system using the F-35’s Internal Communication System cable, enabling maintainers to communicate with pilots without requiring them to exit the cockpit, a capability Reed described as a significant change from previous practice. “Previously, maintainers relied on relayed communication or were required to wait for pilots to shut down and disembark before troubleshooting could begin. The direct connection the F-35 Lightning II ICS cable provides immediate coordination; this allows ground crews to diagnose and resolve problems while keeping the aircraft operational.”

Handheld radios were also integrated to establish a shared frequency across multiple maintenance sections, covering avionics, ordnance, airframes, and maintenance control, allowing all parties to receive aircraft status updates directly from pilots prior to take-off. “This eliminates secondhand communication across the flight line and allows maintainers to respond immediately with the information they receive directly from the pilot,” Vega said. “Now, instead of relying on a single point of contact, multiple maintenance sections can monitor the same frequency and receive information from the pilot in real time.”
