What the FY2027 request buys

Verbatim from the R-2A exhibit for project 0480 of PE 0604261N. 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

Conclude FR-115 DT/OT. Initiate Tactical Open Mission Systems (TOMS) software changes to add the SSQ-145 receiver. Conduct USAB1 DDVLA sonobuoy (SSQ-145) Critical Design Review (CDR).

FY2026 to FY2027 change

FY 2026 to FY 2027 decrease incorporates reductions for higher priorities.

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

MAC-E and USA Blk 1: Conclude MAC-E Operational Testing (OT) concurrent with P-8A OT and IOC MAC-E in Q1/FY26. Continue software improvements for incorporation into the P-8A Training system associated with MAC-E. Conduct data gathering events, data collection and analysis for USA Blk 1. Continue risk reduction prototype engineering and development for USA Blk 1 System-of-Systems capabilities and initiate USA Blk 1 AOFP software development. Conduct MS-B to enable acceleration of program and initiate contracts for the DDVLA sonobuoy (SSQ-145) and AOFP software.

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 89% of project 0480's FY2027 request and 73% of PE 0604261N'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.
