### Project 644862 — Installation Resiliency

The Installation Resilience (IR) project ensures continuity of critical missions that require energy availability throughout any potential disruption through the development and demonstration of technologies in the areas of (1) Advanced Nuclear, (2) Resilient Energy Technology, (3) Flightline Modernization, (4) Energy for the Tactical Edge, and (5) Digital Ecosystem for Enhanced Mission Readiness . These energy-focused efforts facilitate implementation of validated solutions that improve energy security and the resilience of Department of the Air Force supporting infrastructure - a critical and integral component of all weapon systems. This program element included all necessary expenses required to manage, execute, and deliver weapon system capability. The use of such program funds would be in addition to the civilian pay expenses budgeted in program elements 0605829F, 0605831F, 0605833F, and 0605898F.

| Activity (R-2A) | FY2025 | FY2026 | FY2027 |
|---|---|---|---|
| Installation Resilience | 24.6 | 16.0 | 61.0 |

> R-2A activities carry the prior, current and budget year only — no five-year plan. Coverage is partial, so count them, never total them.

### Project 644861 — Operational Energy

The Operational Energy projects develop, mature, prototype, and demonstrate technologies, software, and processes focused on optimizing energy usage to maximize combat capability. Activities include the necessary prototyping and technology validation to enable transition of technologies, software, and processes in the areas of (1) Mission Planning and Scheduling Optimization, (2) Mobility Fleet Optimization (including cargo efficiency improvements), (3) Operational Energy Optimization Technologies, and (4) Energy Supply Chain and Logistics. These energy-focused efforts facilitate implementation of validated solutions that increase weapon system and platform capabilities (range, endurance, number of sorties refueled, etc.) and mitigate supply chain risk for DoW's largest consumer of operational energy, the Department of the Air Force. This program element included all necessary expenses required to manage, execute, and deliver weapon system capability. The use of such program funds would be in addition to the civilian pay expenses budgeted in program elements 0605829F, 0605831F, 0605833F, and 0605898F. The FY 2026 spend plan amount for Operational Energy includes $34.909 million of discretionary and $102 million of mandatory (reconciliation) for a total of $136.909 million.

| Activity (R-2A) | FY2025 | FY2026 | FY2027 |

## Where the FY2027 request goes

| Category | Share | $M |
|---|---|---|
| Government labs & warfare centers | 1.5% | 0.9 |
| Other / unspecified | 99% | 60.1 |

> R-3 exhibit contract funding, not USAspending obligations.

## Mission & acquisition strategy

The Operational Energy and Installation Resilience program develops, matures, prototypes, demonstrates, and assesses technologies, software, and processes to create an energy-optimized force that maximizes combat capability in response to Department of the Air Force warfighters needs. Energy is a cross-cutting pervasive need across every weapon system, platform, installation, and austere operating location.

The efforts within this program employ multiple acquisition strategies to include leveraging existing Federal Acquisition Regulatory-based contracts and Other Transactional Authority (OTA) agreements, as appropriate.
