Propulsion (PP)
Abstract
Propulsion F135 projects within the Continuous Capability Development & Delivery (C2D2) are provided for developmental efforts for propulsion systems and test engine requirements such as Block 4 Integrated Flight Test Support, Engine Flight Test Mechanics, Flight Test Engineering, Engine Hardware, Test Engine Procurements, research, component, and capability development, prototypes, various studies, costs integral to support the developmental stages for F-35 engine modernization, affordability drivers for top engine availability degraders, and improvement to support the F135 Propulsion System for the F-35 Air Vehicle. Testing and development of the three F-35 aircraft variants require engine propulsion funding to enable continued flight hours. Flight hours are budgeted and planned to meet the Block 4 Flight Test timelines and required Flight Test support. Flight Test Support efforts will transition to Organic support by CY2027. Transition of Flight Test Support requirements to organic capability includes efforts performed by contractor and government installations, Autonomic Logistics Information System / Operational Data Integrated Network (ALIS/ODIN) transition, replacement of development-only hardware, and updating Joint Technical Data (JTD) packages as required. The F-35 engine is being modernized as part of the Engine, Power, and Thermal Management System (PTMS) Modernization (EPM) subprogram. In FY24, Engine Modernization began being funded through the standard funding process. EPM Engine Modernization will continue funding propulsion system EMD in FY2025. In FY24 EPM began funding the Power and Thermal Management Upgrade, an upgrade to the F-35 Air System's (AS) Power and Thermal Management System (PTMS), Fuel Thermal Management System (FTMS) and Electrical Power System (EPS).
