## Summary

This activity requests $56.9M in FY2027, 86% of project 3359, up 36% on FY2026. The R-2A exhibit describes it across FY2026–FY2027, including what the FY2027 money is planned to buy.

## What the FY2027 request buys

**FY2027 planned work.** Avionics will continue with software integration, system integration laboratories, development testing and Model Based Systems Engineering (MBSE) activities associated with SCS. Continue design, development and testing for Digital Interoperability (DI) improvements, to include Adaptive Network Wideband Waveform 2 (ANW-2), Link-16 Mission Commander/Strike Intercept (J12), portable tablet improvements for Marine Air-Ground Task Force, Advanced Data Transfer System (ADTS), Small Tactical Terminal (STT), and a switch and Cross Domain Solution (CDS) that support NSA security requirements for airborne networks. Continue Digital Interoperability (DI) development of Net enabled weapons control (J.11) to enable receiving and transmitting near real-time battlefield tactical intelligence and targeting information. Begin Digital Interoperability (DI) Increment III hardware and software efforts that are compatible with Proliferated Low Earth Orbit (pLEO). Continue to develop and test communication solutions for inclusion of Variable Message Format (VMF) for ARC-210 RT-1939 / RT-2036 Radios. Avionics components / systems obsolescence mitigation efforts including, Health and Usage Monitoring System (HUMS), peculiar avionics support equipment, automatic test equipment, Digital Interoperability, and mission computer SCS improvements. Continue enhancement of digital map and data storage capabilities, digital video recording, display systems, digital systems upgrade. Continue design, development, and test on Terrain Awareness Warning System (TAWS) II. Develop Embedded Global Positioning System (GPS)/Inertial Navigation System (INS) Modernization; or EGI-M, to provide open architecture that enables rapid responses to future threats. The fully modernized system integrates new M-Code capable GPS receivers, providing interoperability with civil controlled air space, and implements a new resilient time capability and will include a federated Radar Altimeter (RADALT) solution. Avionics improvements include test asset components to support software and cybersecurity testing efforts.

**FY2026 to FY2027 change.** FY2026 to FY2027 increase to Avionics supports H-1 Modernization efforts to includes Health and Usage Monitoring System (HUMS) and Digital Interoperability (DI) - pLEO. Additionally, Avionics will managing obsolescence and integrating next-generation systems for navigation, safety, and mission processing.

## Before the request year

**FY2026 plans — current year.** Continue with software integration, system integration laboratories, Development Testing (DT) activities associated with SCS and Model Based Systems Engineering (MBSE). Continue design, development and testing for Digital Interoperability (DI) improvements, to include Adaptive Network Wideband Waveform 2 (ANW-2) UH-1Y Aft Cabin Display for situational awareness, portable tablet improvements for Marine Air-Ground Task, Advanced Data Transfer System (ADTS), Small Tactical Terminal (STT), and a switch and Cross Domain Solution (CDS) that support NSA security requirements for airborne networks. Begin Digital Interoperability (DI) development of Net enabled weapons control (J.11) to enable receiving and transmitting near real-time battlefield tactical intelligence and targeting information. Continue to develop and test communication solutions for inclusion of Variable Message Format (VMF) for ARC-210 RT-1939 / RT-2036 Radios. Avionics components / systems obsolescence mitigation efforts including, Health and Monitoring System Upgrade (HMU), peculiar avionics support equipment, automatic test equipment and mission computer SCS improvements. Continue enhancement of digital map and data storage capabilities, digital video recording, display systems, digital systems upgrades. Continue design and development on Terrain Awareness Warning System (TAWS). Develop Embedded Global Positioning System (GPS)/Inertial Navigation System (INS) Modernization; or EGI-M, to provide open architecture that enables rapid responses to future threats. The fully modernized system integrates new M-Code capable GPS receivers, provides interoperability with civil controlled air space, and implements a new resilient time capability and will include a federated Radar Altimeter (RADALT) solution. Avionics improvements include test asset components to support software and cybersecurity testing efforts.
