The Bell H-13 Sioux was developed in the late 1940s as a light utility helicopter for the U.S. Army, evolving from Bell’s earlier Model 47. It became famous for its reliability, simplicity, and versatility. Designed for observation, training, and medical evacuation, it featured a bubble canopy for maximum visibility and an exposed tail boom. The H-13 saw extensive service during the Korean War, particularly for battlefield medevac missions, earning the nickname “Angel of Mercy.” Its proven design influenced future helicopters, making it an iconic symbol of early military rotary-wing aviation worldwide.
The H-13 Sioux was powered by a single piston engine (Lycoming or Franklin), producing roughly 200–260 hp. It could carry one pilot plus one or two passengers in the bubble cockpit, or a patient on a stretcher for medevac missions.
