Steve Blank's Secret History of Silicon Valley [0] is worth reading, an in-depth introduction to the crucial contributions to the development of semiconductor during the Cold War made by secret military projects.
Edit: I do not understand the downvotes. This blog series was once submitted to Hacker News with 188 upvotes, 48 comments, and a largely positive response [1]. The topic is well-researched by Steve Blank to allow him making a presentation at the Computer History Museum. Recognizing the roles played by military projects in semiconductor history does not imply that the military-industrial complex is the greatest blessing of humanity ever, just like recognizing the scientific contributions of Manhattan Project to nuclear science does not mean that a nuclear war is great to have. To the contrary, one is free to criticize the uncomfortable violence behind today's technology that is not often discussed, like many authors did in recent years.
Steve Blank's "Secret History" leaves off the first 20--30 years of this (where not much happens), but is far more comprehensive and informative:
