The JSF Continuous Capability Development & Delivery (C2D2) efforts provide incremental warfighting capability improvements to maintain joint air dominance against evolving threats. Block 4 capability requirements were initiated through ongoing Service-led operational analysis of warfighting gaps identified in the Fifth Generation Fighter Modernization Initial Capabilities Document (ICD), and through F-35 JSF Block 4 Mission Decomposition analysis completed in FY2014. These analyses served as the basis for the Block 4 Capability Development Document (CDD), staffed through the Air Force Requirements Oversight Council (AFROC) and signed by the USAF Chief of Staff in January 2015. Joint Requirements Oversight Council (JROC) approved the CDD 21 March 2017. Modernization activities in FY2026 continue with the incremental releases of capabilities & execution of continuous development efforts as part of the C2D2 acquisition strategy. Block 4 efforts include a robust weapons integration portfolio and provide new opportunities for International Partners to assess, integrate, and field unique capabilities based on global sovereign requirements. The United Kingdom, Italy, Netherlands, Canada, Australia, Denmark and Norway are participants in F-35 modernization. The program shown here reflects United States Navy funding. Total funding for all Service and International Partners is reported at the accomplishment/planned program level since activities support all aircraft variants. Foreign Military Sales are ongoing separately. PE 0604840M/N replaced PE 0604810M/N beginning in FY2019 due to budget being moved from BA05 to BA07. Beginning in FY2022, separate, distinct project units were established within the Continuous Capability Development & Delivery (C2D2) Program Element, per Congressional direction, to provide traceability between execution and budget requests. Efforts are continued from initial C2D2 Project Unit 2936. The C2D2 structure and budget submissions mirror the Joint Strike Fighters Program Management Office organizational structure in order to provide more transparency and visibility to development efforts across the F-35 enterprise. JUSTIFICATION FOR BUDGET ACTIVITY: This program is funded under OPERATIONAL SYSTEMS DEVELOPMENT because it includes development efforts to upgrade systems that have been fielded or have received approval for full rate production and anticipate funding in the current or subsequent fiscal year.
Mission — Utility and Subsystem Support to Mission Systems
The Power Thermal Management Upgrade (PTMU) program will provide the required power and cooling upgrade to the current F-35 thermal management system to meet the estimates for a 5th Generation F-35 fighter. During development, air vehicle cooling requirements grew to exceed planned bleed air extraction. To provide the necessary bleed air, the engine was required to run hotter, and early engineering assessments indicate that this increase in operating temperature decreases engine life, resulting in earlier depot inductions and an increase in life cycle cost. Future capabilities and mission systems will be limited by PTMS cooling capacity. With threats continuing to develop, the F-35 requires new mission systems to out pace the emerging threats to remain relevant and lethal. This upgrade will consist of modifications to the current Power Thermal Management System (PTMS), Fuel Thermal Management System (FTMS), and Electrical Power System (EPS). This work includes nonrecurring engineering for the development, test, and certification of the upgraded PTMS, FTMS, and EPS systems to ensure suitable cooling is available for future capacities.
