Formelly known as CH-53X, the CH-53K is a general redesign of the CH-53E with new engines, new cockpit layout and a wider cargo hold to allow it to carry a Humvee internally resulting in over twice the lift capacity and radius of action of the previous variant.

The CH-53K is scheduled to achieve its Initial Operating Capability (IOC) in FY2018.
