The skies over the battlefield just got a whole lot louder – and deadlier – for America’s adversaries. Pratt & Whitney, a subsidiary of RTX, has recently aced the initial design review (PDR) for the F135 Engine Core Upgrade (ECU) program.

This critical milestone paves the way for a significant power boost for the F-35 Lightning II, solidifying its position as the undisputed champion of air dominance for years to come.

A Multi-Pronged Power Boost for the F-35

The ECU program isn’t just about raw power. It’s a strategic investment in the future of air combat.

Imagine a fighter jet with an engine that not only roars with renewed vigor but also boasts an extended lifespan and the ability to seamlessly integrate next-generation weaponry.

That’s the reality the F-35 is hurtling towards with the ECU.

This upgrade will benefit all three F-35 variants—the A (conventional takeoff and landing), B (short takeoff/vertical landing), and C (carrier variant)—ensuring that no battlefield scenario is left unaddressed.
