Lt. Col Robert Pridgen on the CH-53K

Posted: 10/19/2009

The CH-53E in U.S. Marine Corps service is planned to be replaced by the CH-53K. The CH-53E is becoming expensive to sustain and has fatigue life issues.

The CH-53K has been designed with maintainers in mind, to keep the aircraft flying.

Key Performance Parameters of the CH-53K are as follows:

    • Net Ready• Range/Payload• Mission Reliability• Logistics Footprint• Sortie Generation Rate/Average Sortie Duration• Survivability• Force Protection

First Flight of the Aircraft is scheduled for 2011, with Initial Operational Capability in 2015 and Full Operational Capability in 2021.



Critical Technologies of the CH-53K are:

    • Rotor Blade—incorporating an improved inboard erosion system• The GE38-1B Engine• Structure• Main Rotor Gearbox• Main Rotorhead• Glass Cockpit

The Aircraft has been designed using a multi-disciplinary design approach.  The CH-53K has increased cabin dimensions over the CH-53E.

Total planned procurement is 156 CH-53Ks. Although the U.S. Navy also operates the MH-53E in a mine-sweeping role, there are no plans at present to replace this aircraft with the CH-53K.

The Preliminary Unit Cost of the CH-53K was quoted by Lt. Col. Pridgen as in the region of $55-75 million.
The Aim is to make the CH-53K the pre-eminent Marinized Heavy-Lift Helicopter in the World.

Note: The CH-53K is a candidate for the Franco-German Heavylift Helicopter Requirement.  Between 60 and 120 Helicopters are envisaged in this program and a political decision is considered to be imminent by the two nations.
