This activity requests $115.0M in FY2027, 100% of project 673030 — a new start with no prior-year and no current-year money. The R-2A exhibit describes it across FY2027, including what the FY2027 money is planned to buy.

New start

This activity requests $115.0M in FY2027 with no prior-year and no current-year funding. There is no incumbent line to compare it with — it did not exist before this President's Budget.

What the FY2027 request buys

Verbatim from the R-2A exhibit for project 673030 of PE 1203165SF. 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

Initiate technology maturation and risk reduction efforts for new PNT Control segment in order to meet the modern threat environment and capitalize on advances in commercial technology; develop technical baseline to utilize open interfaces and MOSA to enable enduring, multi-vendor competition and plug-and-play development; achieve contract ATP; manage cost, schedule, and performance of numerous vendors for control segment development. Initiate efforts to mature technology for increased resiliency and availability across future GPS Segments (Ground, Space, and User Equipment). 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

FY27 funding increased due to FY27 being first year of funding.

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 100% of project 673030's FY2027 request and 100% of PE 1203165SF'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.
