Sikorsky Ch-53e Super Stallion / Ch-53k King Stallion

Tri Rotorcraft

The Sikorsky CH-53 Super Stallion and its successor, the CH-53K King Stallion, represent the most powerful heavy-lift helicopters in the U.S. military inventory. Introduced in 1981, the CH-53E was the first helicopter designed from the outset with three engines, giving it unmatched lifting capacity for shipboard operations, capable of carrying a 16-ton payload or towing disabled aircraft off carrier decks. The Marine Corps has relied on the type for decades to move artillery, vehicles, and supplies in expeditionary environments from the Persian Gulf to the Pacific. The newer CH-53K, which began operational testing in 2018, nearly doubles the external lift capacity to 36,000 pounds and features fly-by-wire controls, composite rotor blades, and significantly improved hot-and-high performance, making it the most capable production helicopter in the world by gross weight and payload. Both variants share the distinctive three-engine configuration and seven-blade main rotor, but the King Stallion's more powerful GE38 engines and advanced transmission allow it to carry triple the payload of the legacy Echo model over the same mission radius. Maximum speed is around 170 knots, with a service ceiling near 18,500 feet. The CH-53K holds multiple records, including the heaviest external load ever carried by a helicopter during testing: a 36,000-pound shipping container lifted to altitude in hot desert conditions. Operational missions range from amphibious assault support and combat search-and-rescue to humanitarian relief, where the type's ability to sling-load heavy equipment into austere landing zones is unmatched. The callsigns in SkyMeter's data (WLFPK, FENIX, THNDR) reflect U.S. Marine Corps heavy helicopter squadrons operating both the E and K models from bases including MCAS Miramar, MCAS New River, and forward-deployed units. SkyMeter has tracked 6 flights across 5 airframes and 1 operators, with distinct routes observed.
