The later version of the YHC-1B fitted with T55-L-7 turbines.

 

Military CH-47As were built around the box-like cabin, which was specified to hold 33 to 44 combat-ready troops. Alternately, 24 casualties on litters (and two medical attendants) could be carried, or bulk cargo of roughly 9,525 kg (21,000 lbs). The lower portion of the cabin was sealed, forming a water-tight compartment that enabled amphibious operation.
