    The YH-19 (company model number S-55) was the first practical single-rotor utility helicopter. Designed for the Air Force for arctic rescue, the S-55 served all U.S. military branches throughout the 1950s, especially during the Korean War and in most major military conflicts of the early Cold War. Highlighted in this image is the tail rotor of the Sikorsky YH-19.
