## What project 673506 buys

F-35 Combat Data Systems (CDS) Program Management Office mission includes investment and modernization activities required for Block 4 development, integration, test and evaluation of Mission Data Hardware/Tools, Reprogramming Verification & Validation Systems (RVVS), and Mission Planning Software/Hardware, which includes the Next Generation Open Mission System (NOMS). Funding related to key deliveries to Electronic Warfare Squadrons and F-35 Operational Squadrons and enables government and contractor labor for mission planning and joint reprogramming enterprise. Other costs support Technology Investment for key Modernization/ Innovation activities and Cloud-based DevSecOps infrastructure. 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. The FY2027 request for Combat Data Systems includes $40,002 thousand of discretionary and $19,000 thousand of mandatory for a total of $59,002 thousand for Block 4 capability development.

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