This activity requests $22.4M in FY2027, 57% of project 1950, down 1.3% 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 1950 of PE 0604558N. 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 design and component selection for the TI-28 S/CC/A configuration. -Complete land based integration testing at the System of Systems level for the emerging new architecture employing a common computing environment and Platform As A Service (PaaS) architecture. -Continue NPES level test and evaluation of cyber hardening measures in a land based test environment. -Generate GFI required for delivery to by the shipbuilder for any TI-28 configuration power, weight, cooling or and cabling changes.

FY2026 to FY2027 change

Decrease from FY26 to FY27 properly scales non-recurring engineering developmental scope of work planned in FY27.

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

-Initiate design and component selection for the TI-28 S/CC/A configuration. -Continue land based integration testing at the System of Systems level for the emerging new architecture employing a common computing environment and Platform As A Service (PaaS) architecture. -Conduct NPES level test and evaluation of cyber hardening measures in a land based test environment. -Update GFI required for delivery to the shipbuilder for any power, weight, cooling or cabling changes required by the shipbuilder to evaluate emerging new NPES architectures.

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 57% of project 1950's FY2027 request and 9.4% of PE 0604558N'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.
