Sikorsky S-65
The Sikorsky CH-53 Sea Stallion was, for decades, the heaviest-lifting helicopter in Western military service, built to carry troops, vehicles, and heavy equipment for the US Marine Corps and several allied militaries. Its large, watertight hull-shaped lower fuselage allows amphibious operations, letting it land briefly on calm water if needed during ship-to-shore missions. It saw extensive combat service from Vietnam through the Gulf War, and export versions remain in active use with several air forces today. Its considerably more powerful three-engine successor, the CH-53E/K Super/King Stallion, has gradually taken over its heaviest-lift missions in US service.
