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

Verbatim from the R-2A exhibit for project 643728 of PE 1206761SF. This is the budget justification's own description of work that has not happened yet — the one thing no other level of the budget carries.

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: the year under way

Prior-year accomplishments and current-year plans from the same exhibit. Context for the FY2027 plan, not a series — an activity partitions its project exactly in the request year, but can under-cover it in earlier years.

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.

Money

Three years, and no five-year plan

An R-2A activity publishes the prior year, the current year and the budget year. The FYDP outyears exist at project and program-element level and are deliberately absent here rather than inferred. Estimate types are colored and never summed into one figure.

This activity is 56% of project 643728's FY2027 request and 37% of PE 1206761SF's. In the request year the activities under a project sum to it exactly; in the current year they under-cover it in about 9% of cases, so an activity's delta can legitimately exceed its parent's and the two must not be compared row to row.
