HitchAI read

This activity requests $40.9M in FY2027, 100% of project 674804 — a restart, funded in FY2025 and zeroed in FY2026. The R-2A exhibit describes it across FY2026–FY2027, including what the FY2027 money is planned to buy.

Restart

This activity was funded in FY2025 ($116.0M), zeroed in FY2026, and requests $40.9M again in FY2027. A restart has an incumbent and a new start does not; with a zero current year there is no percentage to quote, which is why it appears in no growth ranking.

What the FY2027 request buys

Verbatim from the R-2A exhibit for project 674804 of PE 0207253F. 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

Will continue PME development, integration, and test on platform upgrades and associated simulators/trainers, address PME discrepancies as required, and future analysis/ maturation of baseline and capability development activities. Specific efforts include, but are not limited to, the following: • Will continue platform and PME engineering, upgrade, and test activities • Will continue advancing Electromagnetic Attack offensive capabilities • Will continue studies and analysis for current/future baseline development planning • Will continue training systems/simulation lab environments

FY2026 to FY2027 change

Funding increased from $0 to $40,896 thousands in FY 2027 to support BL4 development, test and evaluation, and maturation of AEA technologies.

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 PME development, integration, and test on platform upgrades and associated simulators/trainers, address PME discrepancies as required, and future analysis/maturation of baseline and capability development activities. Specific efforts include, but are not limited to, the following: • Continuing platform and PME engineering, upgrade, and test activities • Continuing advancing Electromagnetic Attack offensive capabilities and expanding frequency coverage • Continuing studies and analysis for current/future baseline development planning • Continuing future capabilities to combat emerging and modern threats • Continuing future external communications upgrades • Continuing training systems/simulation lab environments • Continuing Program Support Costs (PSC)

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 674804's FY2027 request and 61% of PE 0207253F'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.
