| Description |
English: Royal Air Force Radar, 1939-1945. Airborne Interception Radar: AI Mark VIIIB installed in the nose of a De Havilland Mosquito NF Mark XIII night fighter. The transmitter box is at the top, mounted above the scanner hydraulic motor assembly. The rotating scanner is contained in the perspex nose. Photograph taken at No. 10 Maintenance Unit, Hullavington, Wiltshire. Operating at a frequency of 3 GHz (10 centimeters wavelength) powered by the new magnetron tube invented by John Randall and Harry Boot at Birmingham University, UK in 1940, this was the first microwave air intercept radar, used on British warplanes in World War 2 beginning late 1941. The development of microwave radar was a game changer for the Allies during World War 2, credited with significantly shortening the war. |

Licensing
This image is in the public domain because it is a mere mechanical scan or photocopy of a public domain original, or – from the available evidence – is so similar to such a scan or photocopy that no copyright protection can be expected to arise. The original itself is in the public domain for the following reason:
This tag is designed for use where there may be a need to assert that any enhancements (eg brightness, contrast, colour-matching, sharpening) are in themselves insufficiently creative to generate a new copyright. It can be used where it is unknown whether any enhancements have been made, as well as when the enhancements are clear but insufficient. For known raw unenhanced scans you can use an appropriate {{PD-old}} tag instead. For usage, see Commons:When to use the PD-scan tag.  |
