The US Marine Corps has declared initial operational capability for the CH-53K heavy lift helicopter, paving the way for a full rate production decision next year.

Sikorsky, a Lockheed Martin Company designed and manufactures the CH-53K, which enables the US Marine Corps and international militaries to move troops and equipment from ship to shore, and to higher altitude terrain, more quickly and effectively.

"This declaration is a vote of confidence from Marine Corps leadership and demonstrates the critical role of the CH-53K, giving forces more range and agility to conduct expeditionary heavy-lift assault transport of armoured vehicles, equipment, and personnel. This capability is critical in the Indo-Pacific region and around the globe in support of the joint force and allies," said Sikorsky president Paul Lemmo.

This latest announcement positions the programme for a full rate production decision in 2023. The approved acquisition objective is for 200 aircraft, which will be manufactured and delivered by Sikorsky and the supply chain in the US, including dozens of small businesses.

The CH-53K production line in Stratford, Connecticut, is active with seven aircraft in build, including three on schedule to deliver to the Marine Corps this year. There are 46 aircraft fully on contract including four heavy-lift helicopters for the government of Israel and another 14 aircraft on contract for long lead material.

The programme leverages digital thread technologies to achieve sustainment savings as well as increased performance and readiness. The digital thread permeates design, manufacture, operation, and sustainment of the CH-53K.

The CH-53K has been specifically designed with a digitally-enhanced modern maintenance support environment to dramatically improve the maintainer's experience:

• Maintenance times will be reduced by one-third with several physical design features and smart technologies designed and built into the aircraft.
• The digital aircraft feeds into a modern plane-side automated maintenance system that enables advanced diagnostics and proactive support solutions.
• There is a robust support system in place for the CH-53K with spare parts, support equipment, validated repair manuals, and Sikorsky technical experts on the ground to support entry into service.
