Growth in aircraft capability must be matched with propulsion modernization to ensure the full mission capability of the F-35 weapon system, now and in the future.
Designed with the knowledge that operational environments evolve and threats advance, the F135’s modular design and advanced digital architecture allow for spiral development and insertion of both hardware and software.
Pratt & Whitney developed EEP for the F135 with the objective of providing the most cost-effective solution to meet future F-35 propulsion requirements. This means inserting the latest technologies into the F135 without breaking variant commonality, which would drive increased costs into the program.
As the air vehicle grows, so must the engine. To date, there is no propulsion growth requirement or funding commensurate to support planned Block 4 air vehicle upgrades. This needs to urgently change as planned air vehicle growth will soon exceed the current F135’s capabilities.
Without propulsion modernization, there will be substantial operational impacts for F-35 warfighters and sustainment cost increases for the taxpayer.
EEP is the only cost-effective, variant-common modernization solution for the F-35 that can fill this capability gap AND reduce sustainment costs.
