McNamara conducted many cuts during his period as Secretary of Defense. He prematurely ended the F-105 Thunderchief and F-106 Delta Dart program in favor of the F-4 Phantom, merged a Navy interceptor and Air Force strike fighter program together in the F-111 program, and ended the B-70 Valkyrie program over the objections of SAC Commander Curtis LeMay and many members of Congress. He also ended the Enterprise and Long Beach nuclear powered aircraft carrier/cruiser programs after only one ship, instead of the half dozen or so originally planned. McNamara also ended the Air Force manned space program, ending both Dynasoar and Blue Gemini.

During his seven years as Secretary of Defense, McNamara made many more cuts and changes. What if McNamara did not become Secretary of Defense, or his cuts did not occur?
