HitchAI read

Project 127 — Nuclear Prototyping requests $90.0M in FY2027, 29% of the $311.0M requested for program element 0603838D8Z — a new start, with no prior-year and no current-year money. 1 R-2A activity decomposes the request, 1 new this cycle.

New start

This project requests $90.0M in FY2027 with no prior-year and no current-year funding. There is no incumbent line to compare it with — it did not exist before this President's Budget.

What project 127 buys

(U) The primary objective of this effort is to prove technological feasibility and assess the operability of key technologies to meet the most pressing operational needs identified in the 2026 National Defense Strategy and to provide response options to unique deterrence challenges. The near-term focus will be on the identification, maturation, and demonstration of subsystems and components. This effort prioritizes the rapid integration of these components into system demonstrators for field experiments and tests within simulated operational environments. This approach is designed to quickly prove the military utility of the technology and provide actionable data for future acquisition decisions. (U) In parallel, this program will develop a strategic roadmap to guide long-term technology maturation, consistent with the Department of War's vision. This ensures a comprehensive strategy that balances immediate technology demonstrations with the development of enduring capabilities. The goal for these projects is to achieve a Technology Readiness Level (TRL) of 6, making the technology available for transition out of the Science & Technology (S&T) phase and into a formal acquisition program within the Future Years Defense Program (FYDP). Upon successful completion, the technology will be transitioned to a service partner to address validated requirements. (U) Further details are available at higher classification levels.

Funding trajectory

Project 127 funding, FY2025–FY2031

Prior years are actuals, the budget year is the request, and the outyears are the FYDP plan. Estimate types are colored and never summed into one figure. Projects carry the full five-year plan; the activities inside them stop at the budget year.

Inside the project

1 accomplishment / planned program

The R-2A exhibit — the only level of the budget that describes work that has not happened yet. Activities carry the prior, current and budget year only, no five-year plan. Each describes FY2027 work in enough detail to have its own page; the rest are shown here in full. Coverage is partial across the corpus, so count activities, never total them.

(U) The program will conduct engineering feasibility studies and analysis to inform the development of system prototypes. The effort will prioritize technology solutions that demonstrate general military utility and can be rapidly integrated into form, fit, and function prototypes. Concurrently, this program will establish a strategic…
