Brief introduction
The CH-37 was the largest helicopter in the world at the time, the prototype first flew in 1953 and deliveries began in July 1956 with 154 units produced, the CH-37 was one of the last heavy helicopters to use a piston engine, which was larger, heavier and less powerful than the turboshaft engines used in later military helicopters. This resulted in a rather short service life of the model, which was completely decommissioned by the end of the 1960s
Its carrying capacity is also quite impressive, about the same as that of the C-47 transport aircraft. Its cabin is enough for 3 M422 or 26 soldiers or 1 105 gun. It features a front-opening hatch and two external engines.
