## Summary

This activity requests $50.4M in FY2027, 94% of project 0921, up 16% 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.** Continue Lab/Ground/Flight Testing on MH-60R/S for LN-100M. Continue Accurate Navigation System - 3 Modernization (ANAV-3M) development for F/A-18E/F and EA-18G. Continue lab/ground/flight/weapons testing of Accurate Navigation System - 3 Modernization (ANAV-3M) on F/A-18E/F and EA-18G. Complete Statement of Requirements (SOR) and begin platform integration for the F/A-18E/F and EA-18G EGI-M based receiver including hardware design and software missionization . Continue platform integration of MAGR-2K-M on CMV/MV-22B. Complete Preliminary Design Review (PDR) and Critical Design Review (CDR) on CMV/MV-22B. Complete lab/ground/flight/weapons testing of LN-251M on E-2D & P-8A and complete Fleet releases for both platforms. Commence platform integration of LN-351 on CH-53K. Continue missionization to develop CH-53K mission specific requirements for LN-351 integration that will leverage USAF PNT PO contracts. Deliver LN-351 Production Representative Unit (PRU) test articles for E-2D, MQ-4C, and CH-53K. Begin platforms integration for the MQ-4C. Continue missionization to develop UH-1Y/AH-1Z mission specific requirements for LN-351 integration that will leverage U.S. Air Force (USAF) Positioning, Navigation, and Timing Program Office (PNT PO) contracts. Continue providing overarching management, central coordination, government oversight and guidance, shared expertise, and engineering during M-Code receiver development to review M-Code receiver requirements and ensure these requirements support aircraft performance and integration on CMV-22B/MV-22B, E-6B, F/A-18E/F, EA-18G, E-2D, MH-60 R/S, CH-53K, P-8A, MQ-4C, UH-1Y/AH-1Z, and KC-130J. Continue to support USAF Embedded GPS/Inertial Navigation System (EGI-M) GPS receiver development, performance, and certification testing. Continue to support EGI-M GPS receiver program events to include but not limited to Systems Engineering and Technical Reviews (SETR), Integrated Baseline Reviews, Preliminary Design Reviews (PDR) and Critical Design Review (CDR). Continue LN-351M EDM testing on E-2D for lead platform efforts.

**FY2026 to FY2027 change.** Funding increase of $6.916M from FY 2026 to FY 2027 is due to LN-251M, and ANAV-3M interim solution testing for E-2D, P-8, F/A-18E/F, and EA-18G.

## Before the request year

**FY2026 plans — current year.** Continue M-Code interim solution efforts on MH-60R/S with LN-100M. Commence Lab/Ground/Flight Testing on LN-100M for MH-60R/S. Continue Accurate Navigation System - 3 Modernization (ANAV-3M) development for F/A-18E/F and EA-18G. Commence lab/ground/flight/weapons testing of Accurate Navigation System - 3 Modernization (ANAV-3M) on F/A-18E/F and EA-18G. Continue platform integration of MAGR-2K-M on CMV/MV-22B. Complete support platform integration of MAGR-2K-M on E-6B. Continue lab/ground/flight/weapons testing of LN-251M on E-2D & P-8A. Continue missionization to develop CH-53K mission specific requirements for LN-351 integration that will leverage USAF PNT PO contracts. Continued M-Code integration efforts to include, but not limited to, systems requirement review (SRR), structural analysis, electrical power load analysis, human engineering, product support analysis, and missionization for UH-1Y/AH-1Z. Deliver LN-351 test articles for UH-1Y/AH-1Z. Continue providing overarching management, central coordination, government oversight and guidance, shared expertise, and engineering during M-Code receiver development to review M-Code receiver requirements and ensure these requirements support aircraft performance and integration on CMV-22B/MV-22B, E-6B, F/A-18E/F, EA-18G, E-2D, MH-60 R/S, CH-53K, P-8A, MQ-4C, UH-1Y/AH-1Z, and KC-130J. Complete to support USAF Miniaturized Airborne Global Positioning System (GPS) receiver 2000-Modernization (MAGR-2K-M) & Embedded GPS/Inertial Navigation System (EGI-M) GPS receiver development, performance, and certification testing. Complete supporting USAF MAGR-2K-M & EGI-M GPS receiver program events to include but not limited to Systems Engineering and Technical Reviews (SETR), Integrated Baseline Reviews, Preliminary Design Reviews (PDR) and Critical Design Review (CDR). LN-351M EDM testing on E-2D for lead platform efforts. Completed Functional Configuration Audit (FCA) for LN-251M. Complete LN-251M development for E-2D and P-8A.
