The Vought-Sikorsky VS-300 was a helicopter designed by Igor Sikorsky. It first flew on 14 September 1939 and had a single three-blade rotor powered by a 75 horsepower (56 kW) engine. Its first free (untethered) flight was on 13 May, 1940. While not the first successful helicopter to fly, it was the first of the configuration that would later become the most popular.
