This activity requests $58.3M in FY2027, 10.0% of project MD09, up 777% 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 MD09 of PE 0603892C. 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

- Deliver BMD 5.2.2 (Aegis BL 9.C3.2). - Commence 5.2.3 (Aegis BL BL9.C3.3), which includes close-range ballistic missile defense improvements to include updates to the Mission Planner. - Commence PAC-3 integration with BMD 5.2.4 (Aegis BL 9.C3.4), which includes system performance enhancements with close-range ballistic missiles, AN/SPY-1 radar resource optimization, mission planning, and operating in a denied environment. Perform modeling and simulation to support requirements development and initial design, code, integrate and test engineering functions in BMD 5.2.4. Support continued PAC-3 integration and development with BMD 5.2.5 (Aegis BL 9.C3.5).

FY2026 to FY2027 change

Increase from FY 2026 to FY2027 provides for the delivery of the BMD 5.2.2 (Aegis BL 9.C3.2), commencement of the BMD 5.2.3 (Aegis BL BL9.C3.3) and commencement of PAC-3 integration with BMD 5.2.4 (Aegis BL 9.C3.4) in support of the U.S. Navy.

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

Congressional Add: Aegis Weapon System Improvements ($6.650 Million) - Commence BMD 5.2.2 (Aegis BL 9.C3.2) development which includes additional manual search sectors, Space Operations Control Variable Action Button (VAB) implementation, and updates to the Mission Planner.

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 10.0% of project MD09's FY2027 request and 6.3% of PE 0603892C'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.
