Developed as the YHC-14 in 1958 due an US
army 's request for a medium-size turbine powered helicopter, was soon
cancelled on behalf of the biggest CH-47 Chinook of the same company.
However, the US marines test a modified version, the Model 107M , that was
soon accepted as the HRB-1 and with the normalization of 1961 became in
the CH-46
A real workhorse of the US navy and marines since 1965, is primarily used
to provide all-weather day or night assault transport of combat troops,
supplies and equipment.
It was intended to be replaced by the Bell/Boeing V-22 Osprey.
The model 107 was built with license in Japan by Kawasaki as the KV-107
and is also used in Canada as CH-113 Labrador / Voyageur and Sweden as
HKP-4
