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. When the Bf 109 was designed in 1934, by a team led by Willy Messerschmitt and Robert Lusser,

Casualties rose rapidly until HQ Desert Air Force ordered a fighter escort for all Tac.Rs. One of the casualties was on 9 April 1942, a P-40 Tomahawk flown by Lieutenant Gouws on a mission over the Chichiba-Ezzeiat area was intercepted by two Bf 109’s and he was shot down by Luftwaffe flying ace
