The Macchi C.202 Folgore ("thunderbolt") was a World War II fighter aircraft built by Macchi Aeronautica and operated by the Regia Aeronautica (RA; Royal Air Force). Macchi aircraft designed by Mario Castoldi received the "C" letter in their model designation, hence the Folgore is referred to as the C.202 or MC.202. Considered to be one the best wartime fighters to serve in large numbers with the Regia Aeronautica, the Folgore operated on all fronts in which Italy was involved
June 14, 1943: Accompanying a raid by 197 British Lancaster bombers against Oberhausen, Germany, five British Beaufighter night fighters make the first operational use of Serrate, a radar detector and homing device that allows them to home in on German night fighters employing the Lichtenstein airborne radar from up to 80 km (50 mi) away and intercept them. The Beaufighters do not intercept any German aircraft during the raid, however, and 17 British bombers are lost.
