Hans-Joachim Kroschinski (11 May 1920 – 7 January 1995) was a former Luftwaffe fighter ace and recipient of the Knight's Cross of the Iron Cross during World War II.
Serving with 2./JG 54 Kroschinski gained his first known Soviet victory, a MiG-3 on 5 August 1942. He had a total of four by the end of 1942. On 21 December 1944 while flying Focke-Wulf Fw 190 A-9 (Werknummer380360—factory number) "Yellow 6", he shot down five Petlyakov Pe-2 bombers, making him an "ace-in-a-day", but was then seriously wounded by return fire from other Pe-2s over Frauenburg. He bailed out of his Fw 190 but as a result of his wounds lost both eyes and his right leg.
Lieutenant Hans-Joachim Kroschinski was credited with at least 76 victories, all recorded over the Eastern Front in 360 missions, including 240 low level attacks. Included in his total is 15 Il-2 Sturmoviks, 2 tanks, a Gun Boat on Lake Ladoga, and 2 MTB's in the Finnish Bay.
According to Heaton, Lewis, Olds and Schulze, Kroschinski was credited with 76 aerial victories. Spick also lists him with 76 aerial victories claimed in 360 combat missions. Mathews and Foreman, authors of Luftwaffe Aces — Biographies and Victory Claims, researched the German Federal Archives and found documentation for 74 aerial victories, plus two further unconfirmed claims, all of which claimed on the Eastern Front.
