## Summary

This activity requests $15.6M in FY2027, 21% of project 643726, down 33% 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 integration and test towards Initial Operational Capability and Full Operational Capability. Perform test and integration activities with PTW-capable modems necessary to expand PTW capability to other Services and user groups. Witness and support PTES integration and test events, including validation and verification activities and test scenario developments. Support software qualification testing, regression testing, capability demonstrations, risk reduction events, and cybersecurity assessments required to achieve Authorization to Operate. Rapidly respond to implement system resiliency and situational awareness necessary to operate in the contested space domain. Activities may include, but are not limited to program office support, studies, technical analysis, experimentation, 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.

**FY2026 to FY2027 change.** Decrease is due to progress made on subsystem development, and test planning on the path to achieving Initial Operational Capability and Full Operational Capability.

## Before the request year

**FY2026 plans — current year.** Initiate Development and Operational Test towards Initial Operational Capability and Full Operational Capability. Perform test and integration activities with PTW-capable modems necessary to expand PTW capability to other Services and user groups.
