## What project 673508 buys

The F-35 Joint Program Office equips U.S. and allied forces with operational F-35 weapon systems in support of military and national security operations. The acquisition and product support workforce provides cutting edge weapon systems, sustainment capabilities, and is charged with providing management, tools, and technical and business capabilities needed to oversee acquisition programs throughout their life cycle. The acquisition workforce funded in this program element will support development phases of acquisition programs to include material solution analysis, technology development, engineering and manufacturing development. This funding does not include costs for base operating support civilian personnel. This program element supports both civilian pay and non-pay support requirements. Additional infrastructure and program management support costs include travel, supplies, contractor support including advisory and assistance support, off-base lease costs, program office IT, cybersecurity, model-based systems engineering, and risk reduction studies including audit readiness and affordability initiatives directly related to C2D2 development efforts. 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. Funding allocations at the project level have historically been subject to change due to the complexity of the F-35 budget structure and cost share ratios. The program will ensure any within-PE adjustments during execution year are reflected in future budget submissions.

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