Boeing , which merged with McDonnell Douglas in 1997, continued to manufacture C-17s for export customers following the end of deliveries to the U.S. Air Force. Aside from the United States, the C-17 is in service with the United Kingdom , Australia , Canada , Qatar , United Arab Emirates , NATO Heavy Airlift Wing , India , and Kuwait . The final C-17 was completed at the Long Beach, California plant and flown on 29 November 2015. [4]

In the 1970s, the U.S. Air Force began looking for a replacement for its Lockheed C-130 Hercules tactical cargo aircraft. [5] The Advanced Medium STOL Transport (AMST) competition was held, with Boeing proposing the YC-14 , and McDonnell Douglas proposing the YC-15 . [6] Though both entrants exceeded specified requirements, the AMST competition was canceled before a winner was selected. The Air Force started the C-X program in November 1979 to develop a larger AMST with longer range to augment its strategic airlift. [7]

Alternative proposals were pursued to fill airlift needs after the C-X contest. These were lengthening of C-141As into C-141Bs, ordering more C-5s, continued purchases of KC-10s , and expansion of the Civil Reserve Air Fleet . Limited budgets reduced program funding, requiring a delay of four years. During this time contracts were awarded for preliminary design work and for the completion of engine certification. [8] In December 1985, a full-scale development contract was awarded, under Program Manager Bob Clepper. [9] At this time, first flight was planned for 1990. [8] The Air Force had formed a requirement for 210 aircraft. [10]
