Nordmann claimed 78 aerial victories, 69 of which on the Eastern Front, achieved in flying over 800 combat missions.[3] Matthews and Foreman, authors of Luftwaffe Aces — Biographies and Victory Claims, researched the German Federal Archives and found records for 75 aerial victory claims, plus two further unconfirmed claims. This number includes 1 claim over Poland, 8 on the Western Front, and 66 on the Eastern Front.[16]
