What the FY2027 request buys

Verbatim from the R-2A exhibit for project 3301 of PE 0604501N. 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 ACE Phase 2 development and complete demo - Continue SBNCTR Phase 2A development to include integration of other sensors, and complete Integration and Test - Continue TNC Phase 1/2 development - Continue EA improvements technology development - Continue Radar Improvements Analysis - Continue ERACE Backfits - Continue ERACE Phase 3 development and conduct IPR #1 - Continue MMSP-R development to support AEGIS Modernization due to DMSMS and obsolescence issues - Continue MMSP-R ECP/software updates - Continue MMSP Next Generation requirements definition - Commence DMSMS Redesign/COTS Replacement

FY2026 to FY2027 change

- Increase in FY27 supports the commencement of MMSP DMSMS redesign and replacement of COTS computing infrastructure and hardware.

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.

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 100% of project 3301's FY2027 request and 33% of PE 0604501N'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.
