This activity requests $15.6M in FY2027, 21% of project 643726, down 33% 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 643726 of PE 1206760SF. 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 integration and test towards Initial Operational Capability and Full Operational Capability. Perform test and integration activities with PTW-capable modems necessary to expand PTW capability to other Services and user groups. Witness and support PTES integration and test events, including validation and verification activities and test scenario developments. Support software qualification testing, regression testing, capability demonstrations, risk reduction events, and cybersecurity assessments required to achieve Authorization to Operate. 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, 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

Decrease is due to progress made on subsystem development, and test planning on the path to achieving Initial Operational Capability and Full Operational Capability.

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 Development and Operational Test towards Initial Operational Capability and Full Operational Capability. Perform test and integration activities with PTW-capable modems necessary to expand PTW capability to other Services and user groups. Witness and support PTES contractor-led events, including validation and verification activities and test scenario developments. Support software qualification testing, regression testing, capability demonstrations, risk reduction events, and cybersecurity assessments required to achieve Authorization to Operate.

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 21% of project 643726's FY2027 request and 10% of PE 1206760SF'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.
