> **NEW START.** $10.3M requested in FY2027 with no prior-year and no current-year funding.

## Summary

This activity requests $10.3M in FY2027, 4.0% of project 634920 — a new start with no prior-year and no current-year money. The R-2A exhibit describes it across FY2026–FY2027, including what the FY2027 money is planned to buy.

## What the FY2027 request buys

**FY2027 planned work.** Continue development of component technologies - Activities include design advancement of intelligent power distribution, design advancement of engine-agnostic power generation, and planned initial testing of affordable power generator hardware. Complete aircraft-scale power generation subsystem concept design - Activities include identification of high-tech risk components and controls development. Commence development and demonstration of integrated architectures for autonomous collaborative platforms - Activities include model-based systems engineering informed early design of electrical power system and thermal management system demonstrations.

**FY2026 to FY2027 change.** FY 2027 funding increased by $10.286 million due to the transfer of the Power & Thermal Systems Integration and Demonstration effort and associated funding within this Program Element from Project 634927 / Flight Systems Control to Project 634920 / Flight Vehicle Tech Integration (now called Aerospace Systems Integration and Demonstration). This includes an increase from FY2026 to FY2027 of $3.829 million due to programmatic adjustments to the DAF Science and Technology portfolio. This reduction reflects a strategic realignment to optimize core research areas and improve resource efficiency.

## Before the request year

**FY2026 plans — current year.** In FY 2025 and FY 2026, the Power & Thermal Systems Integration and Demonstration effort and funding were reported in Program Element 0603211F / Aerospace Technology Dev/Demo /Project 634927 / Flight Systems Control. FY 2025 funding was $8.082 million and FY 2026 funding is $14.115 million.

## Funding

| Fiscal Year | Estimate Type | Amount ($M) |
|---|---|---|
| FY2025 | Actual | 0.0 |
| FY2026 | Enacted | 0.0 |
| FY2027 | Request | 10.3 |
