> Most people don't think of WWII as being a theater with particularly advanced electronic warfare going on. Ehh? At a minimum, WWII was when cryptography and code-breaking became popular. The Battle of Midway was an overwhelming American victory because the USA effectively hacked the Japanese codes and reversed the trap. Thousands of code-breakers were employed to try to crack the Enigma machine, and only one exotic project by Mr. Alan Turing (THE Alan Turing, the father of modern computers) was able to break it. ------ While radios existed in WWI, they were still somewhat exotic. By WWII, every single tank, ship, and airplane was equipped with radios, and those communications were 100% the target of many exotic attacks. England experimented on new forms of Radio, such as RADAR. Germany began to use radio-guided missiles (the V1 "Flying Bombs" were radio-guided by Morse Code... primitive by today's standards but obviously open to electronic attack if you could just figure out the codes). WW2 was the start of electronic warfare on every front. Radio-guided weapons, jamming, radar, even cryptography and information security. Sure: these electronics in WW2 were pretty bad by modern standards. But they were still electronics and computers and integral to both the Pacific and European theaters. I'd argue that cryptography and code-breaking is one of the highest forms of electronic warfare, its practically the invention of the information-security fields (HTTPS, SSL, TLS, etc. etc.) that we use to... well... chat on Hacker News, among other things.
