BAE Systems has introduced a new Link 16 testing capability for US Air Force F-16 fighter jets. The upgrade is designed to improve aircraft readiness and reduce maintenance downtime.
It allows technicians to test and validate essential communication systems directly at military bases, rather than sending equipment to off-site facilities.
The new capability supports the Multifunctional Information Distribution System Joint Tactical Radio System (MIDS JTRS), which is used on F-16 aircraft. The system improves how maintenance crews diagnose and verify Link 16 communication equipment during repairs.
BAE Systems said the upgrade will help increase fleet availability for both US and allied military forces. The upgrade has been added to the company’s Versamodule Extensions for Instrumentation, Improved Avionics Intermediate Shop, and Rackmount Improved Avionics Intermediate Shop systems.

These platforms are used by maintenance teams to diagnose avionics problems on military aircraft. The added capability enables technicians to perform faster, more accurate checks directly at operational bases.
According to BAE Systems, the enhanced testing process provides higher-fidelity checks of tactical navigation functions. This means maintainers can better verify whether a MIDS JTRS terminal is fully operational after repairs. Faster testing also helps aircraft return to service sooner.
Meg Redlin, product line director for Advanced Mission Solutions at BAE Systems, said the upgrade supports ongoing modernization efforts inside the US Air Force.
She explained that maintainers can now diagnose failures and confirm system performance without relying on lengthy off-site inspections. The company said this helps increase aircraft availability while lowering maintenance delays.
What Link 16 and MIDS JTRS Do?
Link 16 is a secure military communications network used by NATO members, the US, and allies. It allows aircraft, ships, and ground units to exchange tactical information in real time throughout missions. The system shares encrypted voice, video, and battlefield data, while resisting electronic jamming.
MIDS JTRS is the radio system that enables Link 16 communications on modern military platforms. It is a software-defined radio with four communication channels. The terminal can operate the Link 16 waveform while supporting up to three additional communication protocols simultaneously.
One of those additional systems is Tactical Targeting Network Technology(TTNT). TTNT enables faster, lower-latency communication in contested combat environments. This improves connectivity between military platforms during high-speed operations.

The Department of War has been fielding MIDS JTRS systems across several combat aircraft and command platforms. These include the F-15, F-16, F/A-18, and F-22 fighter aircraft. The technology is also used on naval systems and command-and-control assets.
The upgraded testing capability replaces older support systems used for MIDS Low Volume Terminal equipment. Earlier testing methods provided less operational coverage and often needed more time to verify failures. The new automated process improves efficiency while reducing the need for replacement parts.
Why BAE Systems Upgrade Matters
Modern combat aircraft rely heavily on secure data sharing during missions. Fighter jets now exchange targeting information, navigation data, and threat alerts in real time. A communication failure inside these systems can reduce mission effectiveness and delay operations.
The new BAE Systems capability helps reduce that risk by improving maintenance accuracy. Technicians can isolate faults more quickly and verify repairs immediately after servicing. This also improves line-replaceable unit recovery rates, which lowers operational costs.

BAE Systems provides specialized emulators and software tools to assist avionics technicians during maintenance procedures. These tools simulate working conditions, so maintainers can identify problems more accurately. The company said that this reduces unnecessary part replacements and improves long-term sustainment.
The MIDS JTRS platform also offers advantages over older military radios by combining multiple functions into a single system. It supports tactical data links, tactical air navigation functions, and additional communication protocols without increasing aircraft size or power requirements. This makes it easier to integrate into different aircraft and naval systems.
Data Link Solutions, a joint venture between BAE Systems and Collins Aerospace, manufactures the MIDS JTRS terminal. The system is available in several configurations, including versions with TTNT support. All variants are designed with the same physical footprint as earlier systems, making upgrades simpler for military operators.
BAE Systems said it has delivered more than 700 avionics test stations during the last 45 years. These systems support military and commercial aviation customers in 25 countries.
The company’s testing platforms provide support for radar systems, electronic warfare equipment, flight controls, communication systems, and weapons management technologies.

Work on the upgraded Link 16 automatic test equipment is taking place at BAE Systems facilities in San Diego, California, and Wayne, New Jersey. The program reflects growing demand for faster maintenance cycles and stronger readiness across modern air combat fleets.
As military operations depend on networked warfare, reliable testing and communication systems are becoming a central part of air force modernization plans worldwide.
