The U.S. Marine Corps flew a CH-53E Super Stallion while refueling midair and carrying two vehicles near Yuma, Arizona, during WTI 2-26.
The sortie, executed by crews from Marine Aviation Weapons and Tactics Squadron One, combined dual external lift with aerial refueling, one of the most demanding assault-support profiles in Marine aviation. Conducted during the seven-week Weapons and Tactics Instructor course at Marine Corps Air Station Yuma, the event tested the ability to sustain heavy rotary-wing operations under realistic combat pressure while supporting distributed Marine Air-Ground Task Force operations.

The sortie took place inside MAWTS-1’s seven-week WTI cycle at Marine Corps Air Station Yuma. This was not a simple proficiency flight but a rehearsal for expeditionary combat logistics under realistic operational pressure, designed to prepare Marine aviation crews to support the Marine Air-Ground Task Force in complex and contested environments.
The CH-53E remains the Marine Corps’ legacy heavy-lift workhorse for exactly this kind of mission. Powered by three General Electric T64-GE-416 turboshaft engines rated at 4,380 shaft horsepower each, the helicopter has a top speed of about 150 knots and a maximum takeoff weight of 69,750 pounds with internal load and 73,500 pounds with external load. Its standard range is roughly 540 nautical miles without refueling, and its dual-point cargo hook system is specifically intended to improve control and stability when carrying large sling loads. From its original design onward, the aircraft has been built to move heavy equipment and supplies from ship to shore and then sustain operations inland.
That technical baseline explains why the helicopter in this event could transport two vehicles externally. The aircraft is carrying a dual external load, and the CH-53E’s dual-hook arrangement is central to that kind of task because it reduces load instability and allows larger or more awkward cargo to be moved at useful speeds. The Super Stallion has long been associated with carrying representative heavy loads such as artillery pieces, light armored vehicles, engineering equipment, and tactical support assets. External-lift operations become essential when vehicles, artillery, fuel bladders, or oversized stores cannot be moved efficiently inside an aircraft or over damaged terrain. For commanders, that means wheeled mobility, command vehicles, ammunition carriers, or recovery assets can be inserted directly where road access is poor, blocked, or too dangerous.
The helicopter’s armament is secondary to lift capacity, but it still matters tactically. The CH-53E is fitted with .50-caliber defensive machine guns, typically positioned to provide lateral and rear coverage during vulnerable phases of flight. It is not a gunship and is not intended to perform dedicated attack missions, but it carries enough defensive firepower to suppress threats during approach, touchdown, hook release, loading, unloading, and departure. When a large helicopter arrives low, heavy, and predictable, those few seconds of suppressive fire can determine whether the load reaches the ground intact. In expeditionary assault-support operations, survivability is often less about armor alone and more about a combination of speed, crew coordination, fields of fire, tactical routing, and the ability to exit the landing zone quickly after delivery.
Air-to-air refueling is what turns that heavy-lift function from a local shuttle into a theater-scale maneuver tool. The CH-53E’s refueling probe gives it effectively open-ended operational reach when tanker support is available. Doing that while carrying two vehicles is especially demanding because the crew must manage power margins, drogue closure, formation discipline, fuel transfer, and external-load behavior at the same time. Every variable becomes more sensitive when the helicopter is heavy and the sling loads add drag, oscillation risk, and handling penalties. Yet the payoff is considerable. Heavy equipment can be repositioned much farther inland without stopping at exposed forward refueling points that might themselves become targets. In a contested theater, that reduces dependence on fixed infrastructure and allows forces to sustain maneuver even when traditional ground supply routes are under threat.
From an operational perspective, the ability to move two vehicles in one heavy-lift sortie is significant. It compresses timelines, reduces the number of aircraft required to support distributed units, and lowers cumulative exposure to enemy observation and fire. Instead of launching multiple separate missions for individual tactical vehicles, commanders can place more capability on the ground in a single lift evolution. That may include mobility assets for reconnaissance teams, vehicles for command-and-control elements, utility platforms for logistics detachments, or support vehicles needed to keep an advanced position operational. In expeditionary warfare, where timing and concentration of effect often matter more than sheer mass, that kind of lift efficiency directly supports operational tempo.
MAWTS-1 exists to standardize advanced tactics and certify instructor-level expertise across Marine aviation, and its course culminates in a fully integrated combined-arms exercise that brings together aviation, ground maneuver, logistics, and command-and-control functions. The key point is that this sortie should be read as a combat systems test, not as a stand-alone helicopter vignette. It examines whether the MAGTF can preserve tempo when distances stretch, infrastructure degrades, and tactical resupply must be executed by air under conditions that simulate real operational friction.
There is also a broader force-development message in this event. The Marine Corps is training both its legacy CH-53E fleet and the newer CH-53K King Stallion in advanced heavy-lift and refueling profiles, showing continuity in doctrine as the service transitions to a more capable platform. The CH-53K is designed to lift substantially heavier loads over useful combat radii, particularly in high-and-hot conditions, but the CH-53E continues to carry the operational burden today. That makes events such as WTI 2-26 especially relevant because they demonstrate how the Marine Corps is sustaining current readiness while preparing for the future heavy-lift force.
A heavy helicopter that can refuel in flight and move two vehicles in one external-lift mission gives a naval expeditionary force a way to bypass chokepoints, reinforce isolated detachments, reposition mobility assets after firing, and regenerate combat power where the enemy does not expect it. That is why this WTI sortie deserves attention well beyond Marine aviation circles. It shows the U.S. Marine Corps rehearsing contested logistics, self-protected assault support, and distributed sustainment in a single evolution, using a platform that remains central to expeditionary warfare even as its successor enters service.
