## Summary

This activity requests $166.3M in FY2027, 56% of project 643728, up 31% 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 the development of the PTS-P Enhanced space vehicle. Conduct a CDR event for the space vehicle leveraging previous PTS-P technology maturation. Initiate the manufacturing, build, and test phase of the satellite development by building both payload and bus components and begin integration with long lead items. Conduct modeling and simulation activities on software and hardware development using PTS-P testbed infrastructure to inform early integration and test activities. Initiate space vehicle to ground modifications to integrate with enterprise systems. 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, 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.

**FY2026 to FY2027 change.** Increase due to significant design review activity with CDR, initiation of space vehicle manufacturing, build, and test phase of the Enhanced PTS-P development and increased ground system integration activities.

## Before the request year

**FY2026 plans — current year.** Initiate an additional rapid space payload prototype development effort that enhances an existing PTS-P design with operationally critical and/or technologically low risk enhancements to incrementally deliver rapid anti-jamming capabilities to the warfighter. Conduct a tailored Systems Requirement Review (SRR) and delta Preliminary Design Review (PDR). Prepare and lay groundwork to conduct a Critical Design Review (CDR) in early FY27. Develop the delivery plan of the additional prototype space vehicle and continue the incremental technology maturation and risk reduction effort from the initial PTS prototypes to enable a future cost-controlled PTS-R acquisition. Initiate the order of long lead parts as a key indicator of commitment from both the satellite contractor and government to execute an aggressive RP schedule.

## Funding

| Fiscal Year | Estimate Type | Amount ($M) |

| FY2026 | Enacted | 127.3 |
| FY2027 | Request | 166.3 |

> Prior, current and budget year only — an R-2A activity carries no five-year plan. It sums exactly into its project in the request year and not necessarily in any other.
