ASV (Air to Surface Vessel) designated a family of airborne radars developed by the Alliesduring the Second World War. ASV Mark II was the first true production airborne radar and first came into operational use in late 1940. It was used in a large number of British aircraft types, including the Sunderland, Wellington, Beaufort, and Lend-Lease Hudson and Liberator. Mark III was a centimetric radar using scarce magnetrons, and there was considerable wrangling over the available equipment between RAF Coastal Command and Bomber Command. The very similar American DMS-1000 was installed on Liberators from March 1942 on.
