What the FY2027 request buys
Verbatim from the R-2A exhibit for project 066 of PE 0603183D8Z. 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.
These funds will support projects selected from the FY 2026 JHTO S&T solicitation and those identified through the FY 2026 technology demonstration plans developed by JHTO cross-service Integrated Product Teams. Technologies will be matured and demonstrated in the areas of collaborative engagement with multi-payload deployment mechanisms, novel detonation-based propulsion technologies, rigorous thermal protections system material testing, robust and integrated alternative navigation technologies, additively manufactured radomes and apertures, and utilizing simulation environments to support mission or systems engineering analyses.
The $263.330 million increase from FY 2026 and FY 2027 supports a greater emphasis on operational technology demonstrations that accelerate the integration of advanced capabilities into emerging programs, including enhanced lethality, air-breathing propulsion technologies, and improved navigation. An increase of $45.000 million designated as Munitions - Joint Hypersonics Transition Office Technology Maturation will make investments in assured position, navigation and timing, cooperative engagement, and other classified technologies. A $5.000 million increase for Next Generation Hypersonic Concepts Studies will provide robust analysis based on modeling and simulation to derive technical requirements and drive effective technical trade decisions. An additional $0.330 million accounts for inflation adjustments for non-pay and non-fuel purchases.
FY2026: the year under way
Prior-year accomplishments and current-year plans from the same exhibit. Context for the FY2027 plan, not a series — an activity partitions its project exactly in the request year, but can under-cover it in earlier years.
These funds will support projects selected from the FY 2025 JHTO S&T solicitation and those identified through the FY 2025 technology demonstration plans developed by JHTO cross-service Integrated Product Teams. Technologies will be matured and demonstrated in the areas of robust navigation (to ensure that hypersonic systems arrive at the target), target seeking and target recognition (to increase the hit probability), thermal management and power generation (to reduce hypersonic system size and weight), highly manufacturable heat shields and structures (to improve hypersonic system affordability), scramjet propulsion technologies and design tools (to decrease the development timelines of novel propulsion systems), enhanced weapon effects and warhead system design (to enhance the lethality of hypersonic weapons), and kill chain analysis and demonstration (to better support warfighting objectives).
Three years, and no five-year plan
An R-2A activity publishes the prior year, the current year and the budget year. The FYDP outyears exist at project and program-element level and are deliberately absent here rather than inferred. Estimate types are colored and never summed into one figure.
| Fiscal Year | Estimate Type | Amount ($M) |
|---|---|---|
| FY2026 | Enacted | 20.7 |
| FY2027 | Request | 284.1 |
This activity is 67% of project 066's FY2027 request and 67% of PE 0603183D8Z'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.
