The Squadron In Action series was started in 1971. This series covers the development, testing, and production of aircraft, armored vehicles, and ships. The focus of this book is on the C-17 Globemaster III.
In 1968, the USAF was looking for a replacement of the C-130. They wanted a medium transport that could carry 67 percent more cargo with STOL capabilities. Two companies stepped up with two designs – Boeing with the YC-14 and McDonnell Douglas with the YC-15. McDonnell Douglas was eventually awarded the contract and thus the C-17A was born.
