Rapid avionics testing solution designed to reduce maintenance downtime and improve fleet availability

BAE Systems has completed the development and integration of an upgraded Link 16 testing capability for Multifunctional Information Distribution System Joint Tactical Radio System (MIDS JTRS) terminals installed on U.S. Air Force F-16 aircraft.

The enhancement is aimed at streamlining avionics maintenance processes and accelerating aircraft return-to-service timelines by enabling faster and more accurate on-site diagnostics.

The new automated testing capability has now been integrated into both the Versamodule Extensions for Instrumentation Improved Avionics Intermediate Shop (VXIIAIS) and the Rackmount Improved Avionics Intermediate Shop (R-IAIS). The systems enable maintainers at operational bases to rapidly validate the status and functionality of MIDS JTRS terminals without requiring extended off-site testing procedures.

“This enhanced Link 16 test capability on the R-IAIS system marks a major milestone in our efforts to support the U.S. Air Force’s modernisation efforts,” said Meg Redlin, Product Line Director for Advanced Mission Solutions at BAE Systems.

“Providing more fidelity in testing with tactical navigation functions will enable U.S. forces and allies to rapidly diagnose failures and validate the operational status of their MIDS JTRS terminals on-site, increasing the availability of their aircraft and reducing maintenance downtime.”

ENHANCED TACTICAL CONNECTIVITY SUPPORT

MIDS JTRS provides secure Link 16 connectivity, delivering jam-resistant line-of-sight voice, video, and data communications across air, land, and maritime assets. The upgraded test solution offers improved performance over previous MIDS Low Volume Terminal testing capabilities used on F-16 aircraft.

The system incorporates BAE Systems-developed emulators and software that support avionics shop technicians during terminal testing procedures. The solution assists maintainers in accurately diagnosing faults, verifying repairs, and improving line-replaceable unit recovery rates, while reducing the need for additional spare parts procurement.

Link 16 remains one of the primary tactical data link standards used by NATO forces, the United States, and allied militaries to share encrypted real-time operational data.

MIDS JTRS is a four-channel software-defined radio capable of operating the Link 16 waveform alongside up to three additional communication protocols. The system is designed to provide scalable and adaptable communications architectures suited to evolving operational requirements, particularly within contested environments.

The U.S. Department of Defense is fielding MIDS JTRS across multiple combat platforms including the F-15, F-16, F/A-18, and F-22 fighter fleets, as well as naval and command-and-control assets.

LONG-TERM TEST SYSTEM EXPERIENCE

BAE Systems noted that it has supplied avionics test solutions for military and commercial aerospace applications for more than 45 years, delivering over 700 test stations across 25 countries.

The company’s support capability spans organisational, intermediate, and depot-level maintenance environments covering systems such as electronic warfare, radar, communications, display systems, flight controls, fire control systems, and stores management.

Development work on the upgraded Link 16 automatic test equipment is being carried out at BAE Systems facilities in San Diego, California, and Wayne, New Jersey.
