The Sikorsky CH-53K King Stallion is a large, heavy-lift cargo helicopter being developed by Sikorsky Aircraft, owned by Lockheed Martin, for the United States Marine Corps (USMC). The design features three 7,500 shp (5,590 kW) engines, new composite rotor blades, and a wider aircraft cabin than previous CH-53 variants. It will be the largest and heaviest helicopter in the U.S. military. The USMC plans to receive 200 helicopters at a total cost of $25 billion.

The H-53 family of heavy lift helicopters combines power and versatility. They are at home in searing desert heat, arctic cold and everything in between. Flying a range of missions, including carrying cargo, vehicles, artillery and troops, the H-53 is designed to operate on land or at sea. These aircraft provide a key capability that facilitates the United States Marine Corps’ Sea Basing strategy. With the 5 May 2014 roll out of the all new CH-53K, the United States Marine Corps’ launches the next generation of heavy lift that will extend the H-53 legacy well into the future.

The CH-53K model heavy-lift helicopter leverages the lessons learned over 50 years of manufacturing and operational success with its CH-53A/D/E predecessors. Built to thrive in the modern battlefield, the extremely capable CH-53K aircraft will be intelligent, reliable, low maintenance and survivable across the full spectrum of operating conditions for which it was designed. Expeditionary in nature, the CH-53K aircraft will be fully shipboard compatible and capable of operating from austere and remote forward operating bases. The CH-53K helicopter is the Marine Corps' critical land and sea based logistics connector.
