Post First World War German fighters were fitted with electrical synchronizers. In such a gear, a contact or set of contacts, either on the propeller shaft itself, or some other part of the drive train revolving at the same number of revolutions per minute, generates a series of electrical pulses, which are transmitted to a solenoid driven ...
The sector clock was a fundamental part of ground-controlled interception (GCI) before modern computerized systems were put in place for airspace control. The clock face is marked with five-minute red, yellow and blue triangular segments. [4]
This is a list of World War II electronic warfare equipment and code words and tactics derived directly from the use of electronic equipment.. This list includes many examples of radar, radar jammers, and radar detectors, often used by night fighters; also beam-guidance systems and radio beacons.

Interconnection of local generation plants and small distribution networks was greatly spurred by the requirements of World War I, where large electrical generating plants were built by governments to provide power to munitions factories; later these plants were connected to supply civil load through long-distance transmission.

Early models were used commercially from the early 1920s, and adopted by military and government services of several countries, most notably Nazi Germany before and during World War II. [6] Several Enigma models were produced, [7] but the German military models, having a plugboard, were the most complex. Japanese and Italian models were also in ...
