This activity requests $15.4M in FY2027, 49% of project 675, down 2.1% 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 675 of PE 0605604A. 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 maintain and advance M&S threat representation, analytical methodologies and performance analysis tools to conduct SLV analyses of Army C3 systems and technologies to include Army tactical network systems (e.g., network baseline), and C3 components supporting autonomous systems. For T2COM, will continue to maintain and generate kinetic/non-kinetic models and threat emulations to support future concepts development. Will provide component and systems-level performance analyses to inform technology maturation, trade-off decisions, and risk reduction.

FY2026 to FY2027 change

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

Will develop and advance M&S threat representation and performance analysis tools and methodologies to support the survivability, vulnerability and HMI assessment of the Army's priority C4ISR technologies for the FCC and PAEs. For DEVCOM Centers/ARL, will continue to provide cyber and electronic warfare threat representation, and component and systems-level performance analyses to inform prototype technology development, inform design decisions and reduce risks through experimentation and T&E of the Army's priority C4ISR technologies.

FY2025 accomplishments

Developed and advanced foundational cyber and electronic warfare analytical capabilities to conduct analyses and assessments of C4ISR technology survivability as specified by AFC/DEVCOM and AEC highest priority systems including vulnerabilities related to Artificial Intelligence (AI) and CEMA. Provided data and analysis support throughout AFC experimentation and the Future Study Program. For DEVCOM Centers/ARL, provided cyber and electronic warfare threat representation and performance analyses to inform prototype technology developers, influence design, and mature C4ISR technologies and reduce risk.

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 49% of project 675's FY2027 request and 49% of PE 0605604A'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.
