WW2 electronic technology
A very interesting account of systems and devices developed during WW2 concerning mainly electronic radar systems and precision electronic navigation/bombing systems. It includes many "countermeasures" and "jamming" systems developed as well. Some were secreted by the Allies and not used for some time for fear the Germans might unleash the same techniques upon the Allies.
I would say this is a complementary companion book to "Wizard War" by R. V. Jones, who was involved in intelligence work for England's secret establishment during WW2. Very fascinating reading.
