USAAF/ USAF Helicopter Designations

Early USAAF helicopters were given the R for Rotor designation. This was later changed to H for Helicopter, with many of the R aircraft receiving the same H code. After 1962 H went from being a main mission code to being an aircraft type suffix, but the numerical sequence continued on. Helicopters now have at least a two letter code - AH for attack helicopter, UH for Utility or CH for Cargo.
