## Summary

This activity requests $162.1M in FY2027, 100% of project EX2, down 16% on FY2026. The R-2A exhibit describes it across FY2025–FY2027, including what the FY2027 money is planned to buy.

## What the FY2027 request buys

**FY2027 planned work.** Management Services: Funding in FY 2027 provides continued mission essential office operations, programmatic analysis, and functional services in direct support of the LTAMDS Product Office. Funding also supports continued development of formal acquisition documentation in support of acquisition milestones and objectives, management of ongoing contract actions, and LTAMDS operations and reporting. Product Development: Funding in FY 2027 continues critical LTAMDS CI/CD of capability. This includes development efforts in support of software, modeling and simulation, Combat Identification (CID) / Discrimination updates, advanced threat defeat development and integration through continued software integration, delivery, and testing required to support radar enhancements. Funding will also support development and implementation of new signal processing techniques and waveforms to enhance Electronic Attack and Electronic Protect (EA/EP) techniques based on the evolving threat, further enhancing radar survival and effectiveness in contested complex environments. Support: Funding in FY 2027 supports the development, modifications, and integration of the LTAMDS support equipment. Test and Evaluation: Funding in FY 2027 includes the completion of LTAMDS IOT&E informing operational effectiveness of the LTAMDS RS. Additional activities include component contractor verification and developmental testing. Funds provide for Continuous Transformation and Experimentation in Combatant Commands. Funding also supports test and evaluation to support program assessments and progress toward closure of identified performance gaps.

**FY2026 to FY2027 change.** The decrease in FY 2027 from FY 2026 reflects the completion of IOT&E and the program's transition to procurement-related activities.

## Before the request year

**FY2026 plans — current year.** Management Services: Funding in FY 2026 provides continued mission essential office operations, programmatic analysis, and functional services in direct support of the LTAMDS Product Office. Funding also supports continued development of formal acquisition documentation in support of acquisition milestones and objectives, management of ongoing contract actions, and LTAMDS operations and reporting. Product Development: Funding in FY 2026 continues critical LTAMDS Continuous Integration and Continuous Delivery (CI/CD) of capability. This includes development efforts in support of software, modeling and simulation, Combat Identification (CID) / Discrimination updates, advanced threat defeat development and integration through continued software integration, delivery, and testing required to support radar enhancements. Support: Funding in FY 2026 supports the development, modifications, and integration of the LTAMDS support equipment. Test and Evaluation: Funding in FY 2026 includes initiation of the LTAMDS IOT&E informing operational effectiveness of the LTAMDS RS. Additional activities include component contractor verification and developmental testing leading to participation in IFTC 26. Funds provide for Continuous Transformation and Experimentation in Combatant Commands. Funding also supports test and evaluation to support program assessments and progress toward closure of identified performance gaps.
