CH-53K King Stallion

The most powerful helicopter in the Department of Defense, the CH-53K King Stallion is a new-build helicopter that will expand the fleet's ability to move more material, more rapidly throughout the area of responsibility using proven and mature technologies.
Designed to lift nearly 14 tons (27,000lbs/12,247 kg) at a mission radius of 110 nautical miles (203 km), in Navy high/hot environments, the CH-53K is designed to lift triple the baseline CH-53E lift capability. The CH-53K can lift up to 36,000lbs via the external cargo hook. The CH-53K will have an equivalent logistics shipboard footprint, lower operating costs per aircraft, and less direct maintenance man hours per flight hour. It is the only fully marinized helicopter capable of lifting 100% of the Marine Air-Ground Task Force's (MAGTF) vertical "Middle Weight Force." Once fielded, the CH-53K will:

- Support the full range of military operations

- Externally lift two "up-armored" High Mobility Multipurpose Wheeled Vehicles (HMMWV)
(~27,000lbs), Light Armored Vehicles (~31,000lbs), and dual Joint Light Tactical Vehicles (~32,500)

- Feature a cabin section 12 inches wider than the CH-53E, which can internally load 2 x 10,000lb AMC 463L pallets or 5 AMC 463L half-pallets or internally load an HMMWV

- Leverage a next-generation "glass cockpit" Common Avionics Architecture System open architecture design

- Utilize triple redundant fly-by-wire flight controls adding additional survivability, safety and maintenance improvements

- Include fourth-generation high-efficiency composite rotor blades with swept anhedral tips

- Leverage low-maintenance elastomeric rotor head
The CH-53K is the Marine Corps' heavy lift replacement for the CH-53E. There are four Engineering Development Model and three System Development Test Article aircraft in flight test, logging more than 1,000 flight test hours. Delivery to the Marine Corps for operational squadron deployment is expected in 2023-2024. The Marine Corps plans to stand up eight active duty squadrons, one training squadron, and two reserve squadrons to support operational requirements. The Marine Corps' procurement objective is 200 helicopters.
