Despite the potential benefits for the Air Force, the military was satisfied with its expendable boosters and did not need or want the shuttle as much as NASA did. Because the space agency needed outside support, the Defense Department (DoD) and the National Reconnaissance Office (NRO) gained primary control over the design process. For example, NASA planned a 40-by-12-foot (12.2 by 3.7 m) cargo bay, but NRO specified a 60-by-15-foot (18.3 by 4.6 m) bay because it expected future intelligence satellites to become larger.
