What project 675365 buys
The F135 Aircraft Engine Component Improvement Program (CIP) supports the F-35 single-engine fighter propulsion system and provides critical sustaining engineering support for the F135 engine. F135 CIP maintains flight safety (highest priority), corrects service revealed deficiencies, improves system Operational Readiness (OR) and Reliability & Maintainability (R&M), reduces propulsion system Life Cycle Cost (LCC), and sustains the propulsion system throughout its service life. Past investments have reduced warfighter Class A rates and decreased Engine Related Loss of Aircraft (ERLOA) and generated significant returns on investments. F135 CIP, through "Lead the Fleet" operational use and accelerated mission testing, identifies and fixes propulsion-related problems ahead of operational impacts. F135 CIP ensures continued improvements in R&M, which reduce out year support costs. Program RDT&E funding may be utilized to implement innovation insertion, capability insertion, software increments, spiral upgrades, modular component swaps, and other insertions consistent with Modular Open System Architecture. Program RDT&E funding may be utilized to design, develop, integrate, and test weapon system and/or component level open architectures. Program RDT&E funding may be utilized to fund the concept refinement, design, development, integration, and testing of interdependent technologies and common architectures that underpin weapon system and portfolio-wide mission outcomes.

Project 675365 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.
| Fiscal Year | Estimate Type | Amount ($M) |
|---|---|---|
| FY2025 | Actual | 0.0 |
| FY2026 | Enacted | 0.0 |
| FY2027 | Request | 33.6 |
| FY2028 | Outyear | 34.3 |
| FY2029 | Outyear | 34.9 |
| FY2030 | Outyear | 35.6 |
| FY2031 | Outyear | 36.3 |

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. Each describes FY2027 work in enough detail to have its own page; the rest are shown here in full. Coverage is partial across the corpus, so count activities, never total them.
-Execute approximately 80+ AF-funded F135 engine tasks supporting F-35 flying operations. -Conduct accelerated mission test and analytical condition inspection -Address safety of flight, engine component redesign, repair/rework procedures and life limit/mission analysis. -Validate redesigned parts and new repair procedures…

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.
