This activity requests $32.0M in FY2027, 98% of project AET-01, up 686% 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 AET-01 of PE 0603469E. 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

- Investigate fully homomorphic architecture for secure artificial reasoning on platforms in the field. - Develop planning capabilities with artificial intelligence to support operational preparation. - Conduct design study on impacts to integration with current mission planning software. - Investigate forward-looking, machine-driven scenario development capable of identifying critical data sets for situational awareness. - Investigate potential to create a hybrid modeling environment where subject matters experts assess the utility and validity of forecasted scenarios. - Demonstrate feasibility of a potential secure and scalable mobile ad-hoc network for maritime vehicles. - Investigate nonlinear mission architectures to generate decision advantage and optionality overmatch by imposing complexity on the adversary. - Formally evaluate operating system for network appliances. - Generate a library of sensing target features and images that can be used for identification and classification. - Conduct state-of-the-art analysis for current information systems technology and begin tradeoff studies. - Meet with transition partners and government stakeholders to define situational awareness gaps.

FY2026 to FY2027 change

The FY 2027 increase reflects studies and concepts initiations including, but not limited to, the advancement of new technologies to enable homomorphic architecture for secure artificial reasoning, to demonstrate a secure and scalable mobile ad-hoc network for maritime vehicles, and to support enhanced forward-looking, machine-driven scenario development.

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

- Conduct multi-domain studies and assess impact to resilience. - Characterize the range and imaging performance of existing radars using fundamental targets of various sizes and shapes.

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 98% of project AET-01's FY2027 request and 9.7% of PE 0603469E'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.
