Let’s face it, the naked eye can only see so far and it can’t track the really fast stuff. Radar makes up for that natural shortcoming and has become a necessity in warfare. In fact, it’s arguably the main reason that the British won the Battle of Britain.

Ever since the Battle of Britain, folks who wanted — or needed — to put bombs on target in enemy territory needed to disable enemy radar first. Blowing up enemy radar is no easy task as most military forces keep them well guarded. Thankfully, you don’t need to blow up the enemy radar — you just need to make sure it can’t see. During World War II, specialized units, like No. 100 Group of the Royal Air Force, flew a variety of planes modified with jammers with the sole purpose of disrupting radar.
