This activity requests $100.2M in FY2027, 43% of project 664597, down 9.5% 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 664597 of PE 0604759F. 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

Start the following Projects: - Increase Capability of Continuous Flow Hypersonic Ground T&E - Mach 5 Continuous Flow Test Continue the following Projects: - Guided Weapons Eval Facility (GWEF) - Hypersonic Hardware in the Loop (HITL) - Hypersonic Air Defense Effectiveness and Survivability (HADES) - DIADS - True Temperature Mach 7 T&E - Turbine Based Combined Cycle Test Improvements (TBCC) - High Pressure Air Additional Capacity Phase 2 (HPAAC2) - Subscale Modeling 1T/1S Wind Tunnels - Integrated Scramjet Direct Connect Diagnotiscs (ISJDC) - One Mission - Networked Intelligence (OMNI) - Early Operational Capability (EOC) Complete the following Projects: - High Enthalpy Standard Hypersonic Test Article (HESHTA) - Large Scale/High Dynamic Pressure Nozzle for Clean Air Facility; M6 M4 M5

FY2026 to FY2027 change

Funding increased $10.513 million due to: $76.683 million increase for hypersonic test and $64.380 million transfer to construct a new Advanced Battle Management System (ABMS) / Joint All-Domain Command and Control (JADC2) Test Capabilities (AJTC) Facility at Eglin AFB, FL.

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

Complete the following projects: -Gulf Range Enhancement -Imaging Improvement and Modernization Program (IIMP - LRWKC) -Improve Plant Reliability and Efficiency/Transonic Aero Test Capability (IMTPC) [IOC June 2026] -Improve Large Model Supersonic Aerodynamic Ground T&E Capability (ILMSC) [formerly Tunnel 16S Reactivation] -Improved Small Scale Hypervelocity Impact T&E -M6/M8 Nozzle for Tunnel B Continue the following projects: - Guided Weapons Eval Facility (GWEF) - Hypersonic Hardware in the Loop (HITL) - Hypersonic Air Defense Effectiveness and Survivability (HADES) - DIADS - True Temperature Mach 7 T&E - Turbine Based Combined Cycle Test Improvements (TBCC) - High Enthalpy Standard Hypersonic Test Article (HESHTA) - Large Scale/High Dynamic Pressure Nozzle for Clean Air Facility [M6 M4 M5] - High Pressure Air Additional Capacity Phase 2 (HPAAC2) - Subscale Modeling 1T/1S Wind Tunnels - Integrated Scramjet Direct Connect Diagnostics (ISJDC) - One Mission - Networked Intelligence (OMNI) - Early Operational Capability (EOC)

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 43% of project 664597's FY2027 request and 43% of PE 0604759F'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.
