US Navy revives interest in Super Hornet engine upgrades
The US Navy has revived interest in studying a major upgrade of the engine that powers the Boeing F/A-18E/F, EA-18G and two foreign fighters, including the possible addition of new technologies.
In early February, Naval Air Systems Command (NAVAIR) notified industry that it would ask GE Aviation to submit a proposal for a contract for the company’s engineers to perform a study on an “F414-GE-400 core enhancement evaluation”.
“NAVAIR has expressed interest in GE evaluating how our latest engine technologies could be applied to the F414 Enhanced Engine,” GE says.
