**R-2A activity** of project FD5 — Apache Product Improvement  
**Program element:** 0607145A — Apache Future Development  
**Component:** U.S. Army · **Budget Activity:** 7  
**Vintage:** President's Budget PB2027

## Summary

This activity requests $27.4M in FY2027, 89% of project FD5, down 35% on FY2026. The R-2A exhibit describes it across FY2025–FY2027, including what the FY2027 money is planned to buy.

## What the FY2027 request buys

**FY2027 planned work.** Projected Level of Effort (LOE) includes all Non-Recurring Engineering (NRE) and procurement activities associated with developing and integrated system design onto the AH-64E.

**FY2026 to FY2027 change.** Decrease in funding due to the projected completion of all LOE and NRE activities associated with the development and integration of the OCG into the AH-64E platform.

## Before the request year

**FY2026 plans — current year.** Once the contract has been definitized (projected Q4FY25) Non-Recurring Engineering (NRE), testing, and qualification Level of Effort (LOE) will commence. Initial scope includes baselining effort via SRR / IBR, design activity and reviews (PDR milestone). FY26 funding will allow completion of the necessary design, integration and qualification activities required to field the Oil Cooled Generator (OCG) capability as directed material solution to the current air-cooled generator as a safety mitigation.

**FY2025 accomplishments.** Apache PMO will continue to work with the contractor and the Original Equipment Manufacturer (OEM) supplier to conduct Integrated Baseline Review (IBR) and System Readiness Review (SRR) activities. Contractor will also continue limited material procurement to minimize risk of long lead items to the overall qualification program.

## Funding

| Fiscal Year | Estimate Type | Amount ($M) |
|---|---|---|
| FY2025 | Actual | 7.9 |
| FY2026 | Enacted | 42.0 |
