Defense Acquisitions: CH-53K Helicopter Program Has Addressed Early Difficulties and Adopted Strategies to Address Future Risks

The United States Marine Corps is facing a critical shortage of heavy-lift aircraft. In addition, current weapon systems are heavier than their predecessors, further challenging the Marine Corps's current CH-53E heavy-lift helicopters. To address the emerging heavy-lift requirements, the Marine Corps initiated the CH-53K Heavy Lift Replacement program, which has experienced significant cost increase and schedule delays since entering development in 2005. This report (1) determines how the CH-53K's estimates of cost, schedule, and quantity have changed since the program began development and the impact of these changes and (2) determines how the CH-53K's current acquisition strategy will meet current program targets as well as the warfighter's needs. To address these objectives, GAO analyzed the program's budget, schedules, acquisition reports, and other documents and interviewed officials from the program office, the prime contractor's office, the Marine Corps, the Defense Contract Management Agency, and the Office of the Secretary of Defense.
