Sikorsky made the S-70. The Military took the basic airframe and, with
Sirkorsky's blessing and assistance turned it into the aircraft known
as the Blackhawk. The civilian off the shelf helo is an S-70. . .or
something like that.
Like the Aerospatiale SA 365N Dauphin is not the USCG Dolphin. They look alike, but are not the same.
