This activity requests $32.7M in FY2027, 100% of project 65A039, down 8.1% 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 65A039 of PE 1206422SF. 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

Complete integration and test for WSF-M SV-2. Complete launch preparation activities, including Day-in-the Life and Integrated Crew Exercises. Conduct SV-2 Launch and Early On-orbit Test Activities and post-launch calibration/validation activities. Conduct on-orbit trending analysis factory reach-back and operational support for SV-1 and SV-2. 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

FY 2027 decrease due to completion of WSF-M SV-2 build 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

Conduct on-orbit trending analysis factory reach-back and operational support for SV-1. Complete integration and test for WSF-M SV-2 and prepare for launch. Initiate launch preparation activities, including Day-in-the Life and Integrated Crew Exercises. Conduct SV-2 pre-ship review ahead of shipment of SV-2 to payload processing facility for launch processing. 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.

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 65A039's FY2027 request and 94% of PE 1206422SF'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.
