This activity requests $30.0M in FY2027, 100% of project 4004, up 34% 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 4004 of PE 0604112N. 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

To continue Primary Hardware (HW) Development for Electrical Isolation and conduct the Critical Design Review (CDR) and Test Readiness Review (TRR); the development of additive manufacturing capability on select EMALS components via the Advancing Additive at Large Scale to Address Readiness and Sustainment (AALSTARS) project; and the development of Block Switch Controller (BSC) Complex Programmable Logic Device (CPLD) and conduct the Critical Design Review (CDR). To incorporate software development for the hybrid Software Support Activity (SSA), Autosuspends frequency reduction, Maintenance Laptop, and Catapult Status Dashboard (CSD). To initiate Windows 10 End of Life transition and EMALS Server & PC-104 Obsolescence replacements.

FY2026 to FY2027 change

Increase from FY2026 to FY2027 is due to the incorporation of software development for the Windows 10 End of Life transition and hardware obsolescence replacements for EMALS Server & PC-104.

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

To complete Automated Software Testing development efforts. To continue Primary Hardware (HW) Development for Electrical Isolation and conduct the Systems Requirements Review (SRR) and Preliminary Design Review (PDR); the development of additive manufacturing capability on select EMALS components via the Advancing Additive at Large Scale to Address Readiness and Sustainment (AALSTARS) project; and the development of Block Switch Controller (BSC) Complex Programmable Logic Device (CPLD) and conduct the Systems Requirements Review (SRR). To incorporate software development for the hybrid Software Support Activity (SSA), Autosuspends frequency reduction, Maintenance Laptop, and Catapult Status Dashboard (CSD).

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 4004's FY2027 request and 27% of PE 0604112N'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.
