## What project 644862 buys

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.

**R-3 lines of work:** Product Development; Support; Management Services.

## What is NOT on this page

Congressional marks, the R-2 mission description and acquisition strategy, the industry vs government split of the whole request, and related program elements are recorded at **program-element** grain — an NDAA mark lands on a PE, never on a project.
