Haas was posted to 5. Staffel (5th squadron) of Jagdgeschwader 52 (JG 52—52nd Fighter Wing) in late 1943.[1] He flew on 385 combat missions,[2] scoring 74 kills over the subsequent year and a half.[3] Haas' squadron was often outnumbered and short on fuel at this late stage of the war.[4]
On 1 February 1945, Haas succeeded HauptmannErich Hartmann as Staffelkapitän (squadron leader) of 4. Staffel of JG 52. On 1 March, this Staffel was renamed and became the 5. Staffel of JG 52. At the same time, the former 5. Staffel was also renamed and became the 6. Staffel.[6][7] At the time, II. Gruppe was based at Veszprém in Hungary.[8]
Haas was shot down over Vienna on 9 April 1945 and, though he managed to bail out from his Bf 109 G at low altitude, he struck the vertical stabilizer and fell to his death.[9] He was posthumously awarded the Knight's Cross of the Iron Cross (Ritterkreuz des Eisernen Kreuzes) in April.[10][11][12] Haas was succeeded by Leutnant Paul Linxen as commander of 5. Staffel.[6] He is buried in Oberwölbling, Austria.[2]
Summary of career
Aerial victory claims
According to Barbas, Obermaier and Spick, Haas was credited with 74 aerial victories claimed in 385 combat missions.[13][14][15] Mathews and Foreman, authors of Luftwaffe Aces — Biographies and Victory Claims, researched the German Federal Archives and found records for 50 aerial victory claims recorded on the Eastern Front.[16]
Victory claims were logged to a map-reference (PQ = Planquadrat), for example "PQ 66671". The Luftwaffe grid map (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 360 square miles (930 km2). These sectors were then subdivided into 36 smaller units to give a location area 3 km × 4 km (1.9 mi × 2.5 mi) in size.[17]
Chronicle of aerial victories
This and the ♠ (Ace of spades) indicates those aerial victories which made Haas an "ace-in-a-day", a term which designates a fighter pilot who has shot down five or more airplanes in a single day.
This and the ? (question mark) indicates information discrepancies listed by Barbas, Mathews and Foreman.
