This activity requests $60.6M in FY2027, 100% of project 660191, up 45% 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 660191 of PE 1206759SF. 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.

FY2026 to FY2027 change

FY 2027 increase of 18.949M will provide technical and administrative support required to execute classified space-related testing, integrated systems end-to-end testing, expanded management requirements to support the programs at Delta and Headquarters (HQ) levels, and evaluate activities intended to prepare Guardians for near-peer competition on timelines directed by the Secretary of the Air Force, and the Chief of Space Operations. The funding increase will also establish USSF Cyber survivability test teams and associated test unit to support the sustained increased USSF weapon system fieldlings

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

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 660191's FY2027 request and 92% of PE 1206759SF'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.
