Summary

Description
English: Royal Air Force Radar, 1939-1945.
Air interception radar: the installation of the AI Mark VIIIA receiver unit on the starboard side of the radar operator's position in a Bristol Beaufighter night fighter. 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, the AI Mark VIII 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.

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.

Note: This tag applies to scans and photocopies only. For photographs of public domain originals taken from afar, {{PD-Art}} may be applicable. See Commons:When to use the PD-Art tag.
