Measuring up

When compared to its predecessor – GE's T64 turboshaft engine powering the CH-53E Super Stallion aircraft – the T408 provides transformational performance improvements. To date, the T408 has logged more than 11,000 hours of ground and flight test in support of a variety of Department of Defense (DoD) programs.


More Power


Better specific fuel consumption


Fewer Parts


Reliable Fix-Forward Design

Impressive power for today’s demanding missions

External Payload

The T408 gives the CH-53K helicopter the power to carry a 27,000-pound external load over a mission radius of 110 nautical miles in hot weather conditions. That’s nearly triple the external load carrying capacity of the current CH-53E Super Stallion aircraft.

Proven technology

The T408 combines breakthrough technologies, innovative cooling schemes, and modern-day durability to deliver numerous mission-critical advantages in the world’s harshest operating environments.

GE’s T408 is equipped with Full Authority Digital Engine Control (FADEC) with prognostics and health management to improve performance and reduce maintenance cost.
