The Army utility-helicopter competition began around 1968, although the exact start is sometimes given as 1967. Its requirement to fit the aircraft inside a C-130 constrained the height and length, as well as provisions for removing or folding components. Air transport allowed urgent reinforcement and the return of damaged helicopters for repair; it did not imply that most helicopters would move by air, especially under 1970s planning assumptions. At the same time, the Navy wanted a helicopter for LAMPS, the Light Airborne Multipurpose System, to replace the Seasprite and considered several candidates. The Black Hawk's large Army production run gave Sikorsky a strong economies-of-scale advantage. A land-service acquisition and its logistics assumptions supplied the affordable basis for a naval helicopter family.

Black Hawk scale and the Navy's LAMPS requirement
The Seahawk grew out of an Army utility-helicopter competition whose C-130 transport limits and large production run made Sikorsky's airframe attractive for the Navy's LAMPS program.
