Prioritizing affordability and utilizing advanced manufacturing techniques, Sikorsky, a Lockheed Martin company, will build nine additional CH-53K King Stallion aircraft at a lower unit price than previous lot buys, resulting in significant savings for the U.S. government and taxpayers. The company’s experienced supply chain coupled with its active digital approach drives speed and affordability throughout design, development, production, and sustainment.
The CH-53K King Stallion will further support the U.S. Marine Corps in its mission to conduct expeditionary heavy-lift assault transport of armored vehicles, equipment and personnel to support distributed operations deep inland from a sea-based center of operations, critical in the Indo-Pacific region.
These nine helicopters are part of 200 aircraft Program of Record for the U.S. Marine Corps with deliveries beginning in 2025.
«By embracing resilient, predictive logistics and sustainment, we are enabling CH-53K King Stallion crews to make smarter, faster decisions, to increase reliability, and improve readiness and material availability at reduced burden to the fleet», said Bill Falk, Sikorsky Director, CH-53K King Stallion programs. «After 50 years of supporting the CH-53E Super Stallion, Sikorsky has a deep understanding of the heavy-lift mission and an enduring partnership with the U.S. Marines Corps enabling our team and our proven supply chain to offer tailored solutions resulting in more efficient missions».
Building to Deliver
The aircraft will be built at Sikorsky headquarters in Stratford, Connecticut, leveraging the company’s digital build and advanced technology production processes.
The factory is active with seven CH-53K King Stallion aircraft in build, and there are 47 more aircraft in various stages of production.
Sikorsky has made significant investments in workforce training, tooling, and machinery to increase the number of aircraft built and delivered year over year.
In total, Sikorsky has delivered five operational CH-53K King Stallion heavy-lift helicopters to the U.S. Marine Corps in Jacksonville, North Carolina, with four more planned for delivery this year.
Marines Flying CH-53K King Stallion in Fleet Environment
The CH-53K King Stallion program operated by the U.S. Marine Corps entered Initial Operational Test and Evaluation in 2021 and is set to conclude in 2022.
Sikorsky has a strong foundation to support the CH-53K King Stallion because the company already provides the U.S. Marines with predictive maintenance on the legacy CH-53E Super Stallion by utilizing the Fleet Common Operating Environment (FCOE) enabling the shift from reactive to predictive maintenance.
The CH-53K King Stallion aircraft is equipped with Integrated Vehicle Health Management System (IVHMS), which will transition the U.S. Marines from fixed interval to on-condition maintenance resulting in lower maintenance crew hours, reduced life cycle costs and increased aircraft readiness.
Lockheed Martin is working with the U.S. Navy on a performance-based logistics contract that expands from the CH-53E Super Stallion to add the CH-53K King Stallion with a contract award expected this year.
