From Strategic bombing of Axis Europe Januari 1943 -September 1944 dated 15 november 1944
"Between late July 1943, when attacks upon the German aircraft industry were launched, and 30 September 1944, a large number of attacks were made on German assembly, component, repair and aero-engine factories. Plants damaged by bombing totalled 58 in 1943, and 146 in 1944. Single-engine fighter aircraft factories bore the brunt of attacks, but production of twin-engine fighters, bombers and miscellaneous types also was materially reduced. Practically all the important aero-engine producers likewise suffered bomb damage ."
