This activity requests $14.1M in FY2027, 11% of project 670131 — a new start with no prior-year and no current-year money. The R-2A exhibit describes it across FY2026–FY2027, including what the FY2027 money is planned to buy.

New start

This activity requests $14.1M in FY2027 with no prior-year and no current-year funding. There is no incumbent line to compare it with — it did not exist before this President's Budget.

What the FY2027 request buys

Verbatim from the R-2A exhibit for project 670131 of PE 0207146F. 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 non-recurring engineering (NRE) and integration development efforts on multiple contracts to develop and integrate open mission systems / multi-function processor (OMS/MFP) with aircraft systems to allow capability to alleviate current ADCP II constraints.

FY2026 to FY2027 change

This is not an FY27 new start. Increase shown based on efforts started in FY2026 using Mandatory funding.

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

Begin non-recurring engineering (NRE) and integration development efforts on multiple contracts to develop and integrate open mission systems / multi-function processor (OMS/MFP) with aircraft systems to allow capability to alleviate current ADCP II constraints.

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 11% of project 670131's FY2027 request and 11% of PE 0207146F'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.
