Russian born Igor Sikorsky began work on helicopters as early as 1910. By 1940, Igor Sikorsky's successful VS-300 had become the model for all modern single-rotor helicopters. He also designed and built the first military helicopter, XR-4, which he delivered to Colonel Franklin Gregory of the U.S. Army.

Russian inventor Igor Sikorsky invented the first practical and useful helicopter. In 1941, his VS-300 craft achieved 92 minutes of fully controlled flight, and the modern helicopter was born. More than 400 helicopters were built to serve the Allied war effort.
