What the FY2027 request buys
Verbatim from the R-2A exhibit for project A61 of PE 0601275A. 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.
Will investigate alternative diamond substrate configurations to enable epitaxial overgrowth of diamond and cubic boron nitride thin films to fabricate high-power, small form-factor radio frequency (RF) devices; research topological, two-dimensional, and magnetic materials and heterostructures to devise concepts for electromagnetic (EM) and event-based sensing for electronic support functions of electronic warfare (EW); explore electrochemical stability and rate capabilities of new battery electrolyte compositions at elevated temperatures; conduct experiments on the electrochemical synthesis of ammonia for energy storage and related photocatalytic ammonia decomposition; conduct experiments on nitride heterostructures to explore the relationships between polarization switching kinetics and semiconductor conductivity, aiming to validate power diversion and amplification concepts; research polarization-sensitive detection of EM signals at wavelengths ranging from infrared (IR) to Terahertz; analyze and validate alpha-voltaic power conversion of ultrawide bandgap (UWBG) aluminum gallium nitride (AlGaN) and diamond vertical device designs coupled to Americium-241 (Am-241) radioisotope for persistent stand-in sensing; investigate optical modulator components derived from potassium tantalate niobate materials in an integrated photonic circuit; explore incorporating constraints in machine learning (ML) surrogate models of complex physical systems; conduct research into ML surrogate models of history-dependent physical systems; model the responsivity of quantum materials to polarized electromagnetic signals; examine how Monte Carlo based materials parameters impact performance of UWBG Technology Computer Aided Design (TCAD) device models.
FY 2027 funding increase reflects the consolidation of other ongoing efforts within this project from Beyond Novel Materials, Compact Non-Linear Elements and Non-Linear Arrays, Novel Materials and Architectures for Emerging Bands and Modalities, Physics Research for Army Innovation, Physics-informed Machine Learning for Complex Phenomena, and Semiconductor Modeling for Advanced Electronics to support the creation of Electronic Warfare (EW) Enabling Electronic and Photonic Physical Phenomena (E3P3).
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) |
|---|---|---|
| FY2027 | Request | 18.1 |
This activity is 64% of project A61's FY2027 request and 28% of PE 0601275A'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.
13 activities in project A61
Every R-2A line of this project, largest FY2027 request first. Linked where the activity has enough of its own narrative to carry a page; the rest are shown in full on the project page.
