This activity requests $31.7M in FY2027, 10% of project AX3, up 0.6% on FY2026. The R-2A exhibit describes it across FY2025–FY2027, including what the FY2027 money is planned to buy.

What the FY2027 request buys

Verbatim from the R-2A exhibit for project AX3 of PE 0604115A. 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

FY27 will continue to leverage National Investments and advances in Signal Intelligence (SIGINT), Electronics Warfare, and Cyber capabilities to prototype increased capability for use and advancement of Army Warfighter Capability.

FY2026 to FY2027 change

The FY27 Iron Sense TMI increase in funding is required to complete the porting of capabilities and the costs required for multiple in theater tests with enough systems to evaluate the user CONOPS and operations.

Before the request year

FY2025–FY2026: what came before

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

FY26 will continue to leverage National Investments and advances in Signal Intelligence (SIGINT), Electronics Warfare, and Cyber capabilities to prototype increased capability for use and advancement of Army Warfighter Capability.

FY2025 accomplishments

FY25 will leverage National Investments and advances in Signal Intelligence (SIGINT), Electronics Warfare, and Cyber capabilities to prototype increased capability for use and advancement of Army Warfighter Capability.

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 10% of project AX3's FY2027 request and 10% of PE 0604115A'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.
