This activity requests $234.6M in FY2027, 77% of project 642407, up 20% 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 642407 of PE 0207606F. 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

FY 2027 is a continuation of FY 2026 efforts to include, but are not limited to, Global Reusable Interface Domain (GRID) development, Next Generation Threat System (NGTS) virtual entities expansion, Weapon Server Common Environment (WSCE) server integration, GRID core services (weather, Infrared, Electronic Warfare, Cyber, Space, data links, communication, etc.), Virtual Airborne Threat Solution (VATS - manned red air) development and Multi Mission Test Platform (MMTPs) refinement. Continue to develop, test, document, and deliver aircraft threat models using threat modeling and analysis. Implement and integrate the collaborative development environment at higher multi-level security within JSE (Impact Levels (IL) 5, 6, and 6+). FY27 environment upgrade support provided by the Navy organic software developers ramps down assuming some workload transfer to Air Force Sustainment Center Software Engineering Directorate.

FY2026 to FY2027 change

FY 2027 funding increased by 39.240 million due to a ramp up in organic Software Engineering Directorate personnel with an increased knowledge base after cross training. Expanding representation of friendly and threat platforms, weapons, and capabilities required to fully represent realistic combat scenarios and assess potential outcomes.

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

FY 2026 is a continuation of FY 2025 efforts to include, but are not limited to, Global Reusable Interface Domain (GRID) development, Next Generation Threat System (NGTS) virtual entities expansion, Weapon Server Common Environment (WSCE) server integration, GRID core services (weather, Infrared, Electronic Warfare, Cyber, Space, data links, communication, etc.), Virtual Airborne Threat Solution (VATS- manned red air) development and Multi Mission Test Platform (MMTPs) refinement. Continue to develop, test, document, and deliver aircraft threat models using threat modeling and analysis. Implement and integrate the collaborative development environment at higher multi-level security within JSE (Impact Levels (IL) 5, 6, and 6+).

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 77% of project 642407's FY2027 request and 77% of PE 0207606F'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.
