RTX’s Pratt & Whitney completes F135 engine core upgrade PDR

Pratt & Whitney, an RTX business, completed the F135 Engine Core Upgrade’s preliminary design review, affirming the ECU’s design is on schedule and exceeding expectations. 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. During the PDR, Pratt & Whitney and 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.
