This activity requests $93.4M in FY2027, 40% of project 664597, up 8580% 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 664597 of PE 0604759F. 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 the following projects: - War-fighter Data Links Test Capability (WDLTC) [Eglin & Edwards] - Advanced Battle Management System Test Capability (ABMS)/Joint All Domain C2 (JADC2) Test Capability

FY2026 to FY2027 change

Funding increased $92.325 million due to construction of a new Advanced Battle Management System (ABMS) / Joint All-Domain Command and Control (JADC2) Test Capabilities (AJTC) Facility at Eglin AFB, FL, via the Defense Laboratory Modernization Program (DLMP).

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

Start the following projects: - Advanced Battle Management System Test Capability (ABMS)/Joint All Domain C2 (JADC2) Test Capability Continue the following projects: - War-fighter Data Links Test Capability (WDLTC) [Eglin & Edwards]

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 40% of project 664597's FY2027 request and 40% of PE 0604759F'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.
