Description
RTX company Pratt & Whitney has completed the F135 Engine Core Upgrade's (ECU's) preliminary design review (PDR), a major step on the way towards creating a Block 4 version of the engine for Lockheed Martin's F-25 fighter aircraft.
The F-35 Joint Program Office evaluated the ECU's design changes and propulsion technologies, both of which are needed to restore full life to the engine and provide improved performance to enable next-generation weapons and sensors.
The upgrade will deliver increased engine durability and performance that will fully enable Block 4 and beyond capabilities for all three variants of the F-35 worldwide.
US Navy F-35 propulsion programme manager Capt. Mitchell Grantsaid: “The PDR was a successful first step towards the capability the ECU will provide in meeting the challenging performance and durability requirements of the F135.
“The ECU will ensure that the US and our international partners remain well positioned to outpace adversary threats.”
In September 2022, Raytheon and Pratt & Whitney received a $232.78 million contract to procure material and support equipment for depot-level F135 engine maintenance facilities and unit-level support equipment at various locations by September 2025, including sites in Australia, Japan, the Netherlands, Norway and the US.
