## What project 657011 buys

The Long Range Stand-Off (LRSO) Cruise Missile is a long-range survivable stand-off weapon capable of delivering lethal nuclear effects on strategic targets. LRSO will replace the currently fielded Air Launched Cruise Missile (ALCM) and will be integrated on both legacy and future bomber aircraft. The LRSO weapon system will be capable of penetrating and surviving advanced Integrated Air Defense Systems (IADS) from significant stand-off range to prosecute strategic targets in support of the Air Force's global attack capability and strategic deterrence core function. FY 2025 funds continued to design, develop, integrate and test the LRSO weapon system through the EMD contract and continued Developmental Test and Evaluation program execution on B-52. FY 2026 funds continued to design, develop, integrate and test the LRSO weapon system through the EMD contract and continue Developmental Test and Evaluation program execution on B-52. FY 2027 funds continued to design, develop, integrate and test the LRSO weapon system through the EMD contract and complete the Developmental Test and Evaluation program execution on B-52. Milestone C is planned for 3QFY2027. Funds may be used to address emerging or short notice Diminishing Manufacturing Sources and Material Shortage (DMSMS) and supply chain issues. 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 program is conducting Engineering and Manufacturing Development (EMD) tasks to validate requirements to support Developmental and Operational Testing, and Production Readiness.

**R-3 lines of work:** Product Development; Support; Test and Evaluation; 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.
