CH-53K King Stallion

Mission

The CH-53K will transport Marines, heavy equipment and supplies during ship-to-shore movement in support of amphibious assault and subsequent operations ashore.


Description

The CH-53K is the United States Marine Corps’ (USMC) heavy lift replacement for the CH-53E. The most powerful helicopter in the Department of Defense, the CH-53K 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 (27,000 lbs/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 with an equivalent logistics shipboard footprint, lower operating costs per aircraft, and less direct maintenance man hours per flight hour. The CH-53K is currently on track to provide an initial operating capability in 2019. The USMC’s procurement objective is 200 helicopters.
