**R-2A activity** of project AA3 — Single Investigator Basic Research  
**Program element:** 0601102A — Defense Research Sciences  
**Component:** U.S. Army · **Budget Activity:** 1  
**Vintage:** President's Budget PB2027  
**Canonical URL:** https://hitchintel.com/programs/0601102A/AA3/a13  
**Parent:** https://hitchintel.com/programs/0601102A/AA3

> **NEW START.** $21.0M requested in FY2027 with no prior-year and no current-year funding.

## Summary

This activity requests $21.0M in FY2027, 33% of project AA3 — a new start with no prior-year and no current-year money. The R-2A exhibit describes it across FY2027, including what the FY2027 money is planned to buy.

## What the FY2027 request buys

**FY2027 planned work.** Material Sciences: Will explore ferroelectric material nanostructures for new capabilities in secure communication, computing, and electronics; examine precursory ceramic materials for extreme temperatures and pressure applications; investigate complex severe plastic deformation pathways for robust electronic and optoelectronic devices. Physics: Will analyze novel topological materials for resilient communication and data transmission; explore plasmonic nanostructures for improved power efficiency. Electronics and Photonics: Will explore impact ionization in semiconductor materials for uncooled long-wave infrared detection; examine novel pumping and confined nanostructures for high-efficiency, compact ultraviolet (UV) lasers; identify compact semiconductor light sources for optical-based communications.

**FY2026 to FY2027 change.** This is not a new start effort. FY 2027 funding reflects the consolidation of other ongoing efforts within this project from Basic Research in Materials Sciences, Basic Research in Physics, and Basic Research in Electronics and Photonics to support the creation of Physical Sciences. Funding decrease reflects the strategic reallocation of resources to support evolving priorities and objectives.

## Funding

| Fiscal Year | Estimate Type | Amount ($M) |
|---|---|---|
| FY2027 | Request | 21.0 |

> Prior, current and budget year only — an R-2A activity carries no five-year plan. It sums exactly into its project in the request year and not necessarily in any other.
