On January 30 1943, H2S radar was used by RAF bombers for navigation for the first time and so became the first ground mapping radar to be used in combat. Initially it was fitted to Stirling and Halifax bombers and provided a ground mapping capability for both navigation and night bombing.

This develoment, using ten-centimeter radar, (actually 9.1 cm) was possible thanks to the development of the cavity magnetron. later versions of H2S reduced the wavelength used, first to 3 cm and then 1.5 cm, at which wavelength the system was capable of detecting rain clouds.

Later in World War II the Luftwaffe night fighters used Naxos radar detectors to home in on the transmissions of H2S.

The Americans adapted the X-Band version of H2S (H2S Mk VI) as H2X radar which they regarded as a significant improvement and which was tested by the RAF Bomber Command in 1945.
