See main article: Erich Hartmann.
Erich Alfred Hartmann (19 April 1922 – 20 September 1993) was a German fighter pilot during World War II and the most successful fighter ace in the history of aerial warfare. He flew 1,404 combat missions and participated in aerial combat on 825 separate occasions. He was credited with shooting down a total of 352 Allied aircraft: 345 Soviet planes and seven American while serving with the Luftwaffe. During the course of his career, Hartmann was forced to crash-land his fighter 16 times due either to mechanical failure or damage received from parts of enemy aircraft he had shot down; he was never shot down from direct enemy action.
According to US historian David T. Zabecki, Hartmann was credited with 352 aerial victories. Spick also lists Hartmann with 352 aerial victories claimed in 1,425 combat missions, all of which on the Eastern Front. Mathews and Foreman, authors of Luftwaffe Aces – Biographies and Victory Claims, researched the German Federal Archives and found records for 352 aerial victory claims, plus two further unconfirmed claims. This number includes two claims over United States Army Air Forces flown P-51 Mustangs, and 350 Soviet Air Forces piloted aircraft on the Eastern Front.
Victory claims were logged to a map-reference (PQ = Planquadrat), for example "PQ 44793". The Luftwaffe grid map (German: Jägermeldenetz) covered all of Europe, western Russia and North Africa and was composed of rectangles measuring 15 minutes of latitude by 30 minutes of longitude, an area of about 360sqmi. These sectors were then subdivided into 36 smaller units to give a location area 3x in size.
