> **NEW START.** $128.6M requested in FY2027 with no prior-year and no current-year funding.

## Summary

This activity requests $128.6M in FY2027, 100% of project 677825 — a new start with no prior-year and no current-year money. 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.** Complete Preliminary Design Review and begin work on Critical Design review. Purchase long lead hardware and begin prototyping and hardware test efforts. In addition, work will begin on the software and firmware for the hardware design that is chosen and being matured. Rapidly respond to implement system resiliency and situational awareness necessary to operate in the contested space domain while continuing to perform missile warning/missile track/missile defense missions. Activities may include, but are not limited to, program office support, studies, technical analysis, experimentation, risk reduction, prototyping, and activities that may leverage commercial, U.S. Government partnership, and international opportunities to respond to existing and emerging adversarial threats with speed and agility. Collaborate with Government stakeholders to solidify expectations, user needs, and areas for improvement on current operational systems.

**FY2026 to FY2027 change.** FY 2027 program increase is due to FY2026 mandatory funding (Reconciliation Bill) and not included in the previous budget document. Additionally, FY 2027 will procure long lead hardware items and begin prototype testing. Furthermore, design reviews are planned for FY 2027.

## Before the request year

**FY2026 plans — current year.** Complete System Requirements Review and begin initial design efforts. Stand up digital simulation laboratory. Begin purchasing of required hardware for digital receiver and prototype elements. Rapidly respond to implement system resiliency and situational awareness necessary to operate in the contested space domain while continuing to perform missile warning/missile track/missile defense missions. Activities may include, but are not limited to, program office support, studies, technical analysis, experimentation, risk reduction, prototyping, and activities that may leverage commercial, U.S. Government partnership, and international opportunities to respond to existing and emerging adversarial threats with speed and agility. Collaborate with Government stakeholders to solidify expectations, user needs, and areas for improvement on current operational systems.
