This talk is about the history of Silicon Valley but it has a long, interesting section on electronic warfare of WWII, German radars, Allied stuff etc. There is also a nice section on cold war electronics.
It's a video of a talk given at the Haas School of Business at UC Berkeley. It's long. Skip the first ten minutes to get to the stuff.
http://steveblank.com/secret-history/I found this as I was looking around, irritated by an article about the history of Silicon Valley that said it really started in the '80's with a culture formed around hobby computers. What rubbish.
Anyway I really enjoyed this talk. Some of the classified stuff that was happening in my backyard during the Cold War was really something.
