| The USMC ordered 200 CH-53K production aircraft (including the four SDTA aircraft) to stand up 8 active duty, 1 reserve and 1 training squadron to replace the CH-53E Super Stallion.
First helicopter, SDTA #3, delivered for trials and testing on May 2018. Production of the helicopter is forecast to more than double from four (4) aircraft in 2022 to nine (9) in 2023, and then increase by an additional 2/3rds to fifteen (15) aircraft in 2026. It is expected that the CH-53K will remain in production through 2032 and beyond. The 2nd Marine Aircraft Wing (2 MAW) was selected to be the first to begin transition to the CH-53K in 2020 in a process that will continue with the rest of fleet up to FY30. The CH-53K entered Initial Operational Test and Evaluation in 2021 and is set to conclude in 2022. On January 24, 2022 HMH-461 (2 MAW) in MCAS New River became the first operational squadron to receive the CH-53K. In December 2022 the CH-53K entered Full Rate Production (FRP) and squadrons transition continues on schedule. Full Operational Capability is expected for FY2029. |
