What the FY2027 request buys
Verbatim from the R-2A exhibit for project 680 of PE 0603680D8Z. 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.
Fund Year 3 of 3 for Carbon Nanotube Fiber Cathodes for High Power Microwave Weapons, Year 3 of 5 for Harnessing Microbe-Sourced Cellulose for Advanced Fiber Manufacturing, Year 2 of 4 for Affordable Hydrogen On-Demand, Year 2 of 4 for Additive Manufacturing for Hypersonic Radomes, and Year 2 of 3 for Powder Granulation for Expanded Production Capacity of Thermal Batteries. Additional funding being applied to advanced manufacturing of hypersonic radome materials for the defense industrial base.
The increase of $28.000 million between FY 2026 and FY 2027 reflects $15.000 million for Additional Carbon-Carbon Suppliers, $7.000 million for Hypersonic Aperture Manufacturing Development and $6.000 million for Manufacturing and Production Assessments and Improvements for Hypersonics.
FY2025–FY2026: what came before
Prior-year accomplishments and current-year plans from the same exhibit. Context for the FY2027 plan, not a series — an activity partitions its project exactly in the request year, but can under-cover it in earlier years.
Fund Year 4 of 4 for Mobile Fabrication and Repair, Year 2 of 2 for Carbon Nanotube Fiber Cathodes for High Power Microwave Weapons.
Fund Year 3 of 3 for Self-Damping Structural Materials, Lightweight Hydrogen Fuel Cell Separator Plate Manufacturing, Year 3 of 4 for Mobile Fabrication and Repair, and Year 1 of 2 for Carbon Nanotube Fiber Cathodes for High Power Microwave Weapons for DoD.
Three years, and no five-year plan
An R-2A activity publishes the prior year, the current year and the budget year. The FYDP outyears exist at project and program-element level and are deliberately absent here rather than inferred. Estimate types are colored and never summed into one figure.
| Fiscal Year | Estimate Type | Amount ($M) |
|---|---|---|
| FY2025 | Actual | 5.5 |
| FY2026 | Enacted | 8.2 |
| FY2027 | Request | 36.2 |
This activity is 44% of project 680's FY2027 request and 6.2% of PE 0603680D8Z'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.
