This activity requests $64.1M in FY2027, 56% of project 3095, down 12% 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 3095 of PE 0603273N. 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 development of an accelerometer that can handle higher g-loading - Continue development of a radiation hardened inertial measurement unit (IMU) - Continue development of a radiation hardened flight computer - Continue development of navigation aids for challenging environments - Continue advanced hardened actuator development - Continue attitude control system (ACS) development - Further information can be provided at a higher classification level

FY2026 to FY2027 change

The $8.48 million decrease from FY 2026 to FY 2027 is a result of the program's strategic phasing. FY 2026 funding supports the majority of the preparatory work for the integrated aeroshell and GN&C demonstration, while the reduced FY 2027 budget covers the demonstration's execution.

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

- Continue development of an accelerometer that can handle higher g-loading - Continue development of a radiation hardened inertial measurement unit (IMU) - Continue development of a radiation hardened flight computer - Continue development of navigation aids for challenging environments - Begin advanced hardened actuator development - Continue attitude control system (ACS) development - Further information can be provided at a higher classification level

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 56% of project 3095's FY2027 request and 56% of PE 0603273N'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.
