Alternate Title: United States Air Force

"This history continues the story of the complex effort to maintain and develop a reliable ICBM force, under centralized command and control, which could accurately destroy targets thousands of miles away. One part of that story was the Minuteman modernization program, which included the installation of such features as an 'enable command time' as another safeguard against unauthorized launch, development of plans for airborne launch control centers (ALCCs) that could be used to launch remotely 470 Minutemen, and the implementation of an emergency rocket communication system (ERCS) that would enable SAC headquarters to launch the Minuteman force during or after a nuclear strike. Also to ensure tighter control, SAC worked on a cancel launch in process (CLIP) program, which could prevent missile launch up to the moment the silo lid opened up. […]. In addition to the most significant weapon systems, the narrative covers chaff and decoys developed to protect against ABM, problems with developing short-range attack missiles (SRAMs) designed to destroy defensive radars, and hardrock silos that were to withstand overpressures of up to 3,000 pounds per square inch. Moreover, R&D on an Advanced ICBM proceeded, although the Defense Department was not ready to approve deployment during the mid-1970s, partly because it was not convinced of the need for a Minuteman follow-up."
