What the FY2027 request buys

Verbatim from the R-2A exhibit for project 2195 of PE 0604759N. 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

- Complete replacement of the hydrophone tracking system at AUTEC. - Continue the minor upgrade and modernization of test capabilities at AUTEC, Nanoose and Dabob. - Continue replacement of underwater cables to hydrophone arrays at Nanoose and Dabob. - Continue upgrade of T&E target emulator at Nanoose and Dabob. - Continue upgrade of electronic warfare signal generator at AUTEC. - Continue site 2 power plant and lightning protection upgrade at AUTEC. - Continue remotely operated vehicle upgrade at Nanoose and Dabob. - Continue range data management software at Nanoose and Dabob. - Continue upgrade to the acoustic acquisition system at Nanoose and Dabob. - Continue site 1 power plant upgrade at AUTEC. - Initiate subsea cable installation at AUTEC.

FY2026 to FY2027 change

Funding decreases from FY 2026 to FY 2027 due completing the purchase of equipment for hydrophone replacement at AUTEC.

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 19% of project 2195's FY2027 request and 19% of PE 0604759N'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.
