This activity requests $17.3M in FY2027, 4.1% of project 675345 — a new start with no prior-year and no current-year money. The R-2A exhibit describes it across FY2026–FY2027, including what the FY2027 money is planned to buy.

New start

This activity requests $17.3M 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 675345 of PE 0101127F. 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

This is not a FY2027 new start. Development of additional capabilities through further aircraft integration, hardware, software upgrades and testing to include technical data required for permanent TCTO roll on/roll off modification and sustainment planning for version 2.0 EMD efforts.

FY2026 to FY2027 change

Increase in funding for incremental development approach to transition prototype into EMD effort.

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

This effort was initiated by Congressionally approved spend plan for the Congressional add titled "NC3 Modernization and Golden Dome Initiatives"

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 4.1% of project 675345's FY2027 request and 4.1% of PE 0101127F'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.
