## Summary

This activity requests $96.0M in FY2027, 100% of project 650012 — a restart, funded in FY2025 and zeroed in 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.** - Will initiate contract execution activities - Will conduct System Level Design Reviews to enter production - Will start purchase of long lead items - Will start sensor management software suite design, development, and update activities - Will continue buildout and deployment of on-island fiber optic/WAC network segments - Will continue ionospheric modeling to inform target tracking software development activities - Will conduct electromagnetic interference surveys at the transmit site (Babeldaob, Palau) - Will fund program support costs to include DCA manpower, test assets, and initiation of iterative integrated developmental and operational testing

**FY2026 to FY2027 change.** Funding decreased due to purchase of long-lead radar components and material development in FY2026.

## Before the request year

**FY2026 plans — current year.** - Continue market research activities for the acquisition of subsystems - Conduct fiber optic/network design reviews and factory acceptance tests - Conduct system performance analyses with latest ionospheric data - Conduct ionospheric and electromagnetic interference data collections in the receive site (Angaur, Palau) - Continue Model Based System Engineering (MBSE) activities - Start Cybersecurity and Risk Management Framework process for fiber optic cable subsystem - Select system integrator
