Messerschmitt Bf 109 was called the Me 109R, suggesting it was just another variant of the standard fighter, but in fact it was a racing aircraft having little in common with the Bf 109. It was powered by the DB 601ARJ, producing 1,156 kW (1,550 hp), but capable of reaching 1,715 kW (2,300 hp). This world record for a piston-engined aircraft was to stand until 1969, when Darryl Greenamyer's modified Grumman F8F Bearcat, "Conquest I", broke it with a 777 km/h (483 mph) record speed.

Luftwaffe 437,000 Hungarian Jews deported between May and July 1944, about 320,000 were gassed on arrival at Auschwitz and the remainder forced to work. Only 50,000 survived. Almost 1,000 fuselages of the jet fighter Messerschmitt Me 262 were produced at Gusen, a subcamp of Mauthausen and brutal Nazi labor camp, where the average life expectancy was six months. By 1944, one-third of production at the crucial Regensburg plant that produced the Bf 109, the backbone of the "Luftwaffe" fighter arm, originated in Gusen and Flossenbürg alone. Synthetic oil was produced from shale oil deposits by prisoners of Mittlebau-Dora as part of
