World War II Aviation (UHC)

It was not the first helicopter to see military service, but the XR-4 was the world's first mass-production helicopter and the first successful production rotorcraft of single-rotor configuration. The success of this aircraft paved the way for the large-scale introduction of more advanced rotorcraft into military and civilian service. The XR-4 represents the culmination of Igor I. Sikorsky's attempts to create a practical helicopter. This work began in 1909 but did not reach fruition until 30 years later. The XR-4 also helped ushered in training practices and procedures that became standard in all future rotary winged operations in America.
