"The AN/APS-4, originally known as ASH (air-surface, model H) is an early military air to air and air to surface radar used by American and British warplanes during World War II. APS-4 operated in the X band at 3 cm, compared to the 10 cm S band used by most radars of the era. This allowed the antenna to be greatly reduced in size and the unit as a whole to fit into a single streamlined fairing that could be mounted to many aircraft. In American service it was used on many aircraft, including the Douglas C-47 Skytrain, North American P-82D/F/H Twin Mustang, Vought F4U-2\\5N Corsair, Grumman F6F-3/5 Hellcat, Curtiss SB2C-5 Helldiver and Grumman TBF-3 and TBM-3S Avenger. In RAF service it was known as ASV Mark IX and equipped a number of aircraft including the Fairey Firefly, Fairey Barracuda, de Havilland Mosquito and a small number of Grumman Avengers."@en . . .
