Key Points
- A Marine Corps CH-53K King Stallion lifted a Medium Tactical Vehicle Replacement during the Weapons and Tactics Instructor course 2-26 at Yuma, Arizona, showcasing the aircraft’s heavy lift capability in realistic training conditions.
- The exercise underscores the CH-53K’s central role replacing the aging CH-53E fleet, with the new variant carrying nearly triple the external load capacity to sustain Marines across dispersed, contested environments.
A United States Marine Corps CH-53K King Stallion helicopter assigned to Marine Aviation Weapons and Tactics Squadron One lifted a Medium Tactical Vehicle Replacement during a heavy lift training exercise at Auxiliary Airfield II in Yuma, Arizona, on March 31, as part of the Weapons and Tactics Instructor course 2-26.
The exercise is one element of WTI 2-26, a seven-week training event hosted by MAWTS-1 that brings together the most demanding integration tasks Marine aviation performs in support of the Marine Air Ground Task Force, as well as joint and coalition partners. Heavy lift operations — moving vehicles, artillery, fuel, and supplies by air — sit at the core of that curriculum, and the CH-53K is now the primary platform through which the Marine Corps intends to execute that mission at scale.
MAWTS-1 serves as the Marine Corps’ premier aviation training and standardization organization, and its WTI course produces the tactics instructors who carry advanced techniques back to operational squadrons across the service. Graduating a WTI is a significant qualification, and the scenarios run during the course are designed to stress-test the integration of fixed-wing strike, rotary-wing assault and lift, electronic warfare, and unmanned systems into a coherent air-ground operation. Heavy lift exercises involving the CH-53K fit within the course’s broader focus on logistics under fire — the ability to sustain ground forces in contested or austere environments without relying on fixed infrastructure.

The Medium Tactical Vehicle Replacement represents a substantial real-world load. The MTVR is a 7-ton truck used across the Marine Corps to move troops, ammunition, and supplies over rough terrain, and lifting one externally beneath a helicopter places significant demands on both the aircraft and its crew. Performing that task as part of a graded, integrated training course rather than a controlled demonstration reflects MAWTS-1’s emphasis on replicating the conditions instructors and students will face in actual operations.
The CH-53K is the newest and most capable variant of the King Stallion family, which has served as the Marine Corps’ primary heavy lift helicopter for decades. Compared to its predecessor, the CH-53E, the King Stallion nearly triples the external lift capacity, carrying up to 27,000 pounds on an external sling load while also incorporating modern fly-by-wire flight controls, more powerful engines, and a wider cabin. Those improvements allow it to operate effectively at higher altitudes and in hotter ambient temperatures — conditions that significantly degrade the performance of older rotary-wing designs and that are increasingly relevant across potential operating environments in the Pacific and Middle East.
The Marine Corps has been fielding the CH-53K progressively to replace the aging CH-53E fleet, and its incorporation into WTI course events signals that the new platform is now sufficiently mature and available to anchor advanced training at the institutional level.
