Radar in World War II greatly influenced many important aspects of the conflict. [1] This revolutionary new technology of radio-based detection and tracking was used by both the Allies and Axis powers in World War II , which had evolved independently in a number of nations during the mid 1930s. [ 2 ]
Cryptography was used extensively during World War II because of the importance of radio communication and the ease of radio interception. The nations involved fielded a plethora of code and cipher systems, many of the latter using rotor machines .
Work was done using a third transmitter to improve system performance. Range with a normal Freya was up to 250 km, work was underway to use a Wasserman system instead of a Freya to increase range too 350 km. (the Freya signal was too weak to trigger the Fug25a at ranges beyond 250 km), but this was not completed.
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.
The Norden saw reduced use in the post–World War II period after radar-based targeting was introduced, but the need for accurate daytime attacks kept it in service, especially during the Korean War. The last combat use of the Norden was in the U.S. Navy's VO-67 squadron, which used it to drop sensors onto the Ho Chi Minh Trail in 1967. The ...
A toy kaleidoscope. A kaleidoscope (/ k ə ˈ l aɪ d ə s k oʊ p /) is an optical instrument with two or more reflecting surfaces (or mirrors) tilted to each other at an angle, so that one or more (parts of) objects on one end of these mirrors are shown as a symmetrical pattern when viewed from the other end, due to repeated reflection.
World War II marked the first full-scale war where mechanization played a significant role. Most nations did not begin the war equipped for this. Most nations did not begin the war equipped for this. Even the vaunted German Panzer forces relied heavily on non-motorised support and flank units in large operations.
In World War II and earlier submarines, it was the only means of gathering target data to accurately fire a torpedo, since sonar was not yet sufficiently advanced for this purpose (ranging with sonar required emission of an acoustic "ping" that gave away the location of the submarine) and most torpedoes were unguided.
