What project 2555 buys
Integrated Test activities in support of C2D2, to include Lockheed Martin support at all test sites. Non-recurring engineering required to plan for the service life extension of existing DT aircraft and modifications necessary to bring DT aircraft fleet to a more production-representative and sustainable configuration, and to develop flight test instrumentation and release test software to meet Block 4 requirements. Additional upgrades required to support development and evaluation of improvements driven by changes in the threat environment and as identified in the Electronic Warfare ICD, the Fifth Generation Fighter Modernization ICD, and the Block 4 Capability Development Document (CDD). Efforts include non-recurring engineering and procurement of a test article to evaluate service life of F-35B STOVL Aircraft. Integrated test also supports the evaluation of upgrades to ALIS, fielding of ODIN Base Kits, regression testing of fielded weapons upgrades, and various validation/verification efforts. 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 Test & Evaluation includes $142,320 thousand of discretionary funding and $92,299 thousand of mandatory (reconciliation) funding for Flight Science Aircraft and Block 4 capability development.

Project 2555 funding, FY2025–FY2031
Prior years are actuals, the budget year is the request, and the outyears are the FYDP plan. Estimate types are colored and never summed into one figure. Projects carry the full five-year plan; the activities inside them stop at the budget year.

The R-2A exhibit — the only level of the budget that describes work that has not happened yet. Activities carry the prior, current and budget year only, no five-year plan. 4 of them describe FY2027 work in enough detail to have their own page; the rest are shown here in full. Coverage is partial across the corpus, so count activities, never total them.

Read the FY2027 plan →FY2027 planned work Operational Test activities will continue from FY2026 into FY2027 under a level-of-effort OT capacity as defined in the Integrated Test Team (ITT) charter and as required to support Block 4 construct's capability releases. These activities may include OT squadron participation in large force fleet-representative exercises or joint force exercises to stress the capabilities in an operational environment. Funding will also be used to continue refining and improving OT data analysis tools and OT data management.
FY2026 to FY2027 change When considering the FY2027 mandatory funding in addition to discretionary funding, the increase from FY2026 to FY2027 is due to additional operational testing and weapon development tests in FY2027 to support added Tech Refresh 2 software delivery in addition to the TR3 software development lines. This adds additional "for score" OT requirements in addition to the additional OT feedback during development cycle. Additionally, increase accounts for procurement of additional HW modification kits for the OT fleet.
FY2026 plans — current year Operational Test activities will continue from FY2025 into FY2026 under a level-of-effort OT capacity as defined in the Integrated Test Team (ITT) charter and as required to support the C2D2 construct's incremental capability releases. These activities may include OT squadron participation in large force fleet-representative exercises or joint force exercises to stress the capabilities in an operational environment. Funding will also be used to continue refining and improving OT data analysis tools and OT data management.
Named performers on project 2555
Performers named in the R-3 exhibit under this project. Share is of the project's whole FY2027 R-3 total — the same denominator the program-element split uses, so the two read on one scale and will not sum to 100% when unnamed or government work is in the mix. Budget-justification contract funding, not obligations.
