Early Utility Helicopter
The CH-19 Chickasaw was part of the Sikorsky H-19/S-55 family that helped move helicopters into routine military utility service.
The CH-19 Chickasaw traces to Sikorsky's H-19/S-55 design, an early postwar helicopter family used by U.S. military services and allies. The National Museum of the U.S. Air Force identifies the UH-19B as a Chickasaw variant, while broader H-19 histories show the type's use in transport, rescue, liaison, and medical evacuation roles. Its large nose engine installation and elevated cabin arrangement were distinctive features of the family.
