Early life and career

Haiböck was born on 28 February 1917 in Linz in Austria-Hungary. In 1937, he joined the military service of Austrian Air Force. Following the Anschluss in March 1938, the forced incorporation of Austria into Nazi Germany, Haiböck was transferred to the Luftwaffe (the Nazi German Air Force). In 1938, he attended the Theresian Military Academy at Wiener Neustadt and the Luftkriegsschule 2 in Berlin–Gatow.^[1]

World War II

World War II in Europe began on Friday 1 September 1939 when German forces invaded Poland. On 1 December 1939, Leutnant Haiböck joined Jagdgeschwader 26 "Schlageter" (JG 26—26th Fighter Wing), which had been named after Albert Leo Schlageter on 1 May 1939.^[2] There, he was assigned to 9. Staffel (9th squadron).^[3] At the time, the Geschwader was commanded by Oberst Eduard Ritter von Schleich, 9. Staffel by Oberleutnant Gerhard Schöpfel, and III. Gruppe, to which the Staffel was subordinated, was led by Major Ernst Freiherr von Berg.^[4] The Gruppe was based at Werl and patrolled western German border during the "Phoney War" without having contact with the enemy. On 1 November, III. Gruppe was ordered to Essen-Mülheim Airfield.^[5]

Haiböck claimed his first aerial victory on 29 May during the Battle of Dunkirk against the Royal Air Force (RAF). At 18:10, he shot down a Supermarine Spitfire west of Dunkirk. The Spitfire belonged to either No. 64, No. 229 or No. 610 Squadron.^[6] Two days later, he claimed a No. 609 Squadron Spitfire over Dunkirk.^[7] He claimed his last and third aerial victory of the Battle of France on 8 June over a Hawker Hurricane.^[8]

On 15 August, Haiböck claimed his first aerial victories against the RAF during the Battle of Britain. That day, Luftflotte 2 (Air Fleet 2) sent 88 Dornier Do 17 bombers from Kampfgeschwader 3 (KG 3—3rd Bomber Wing) attacking the Rochester and Eastchurch airfields. JG 26 participated on this mission, flying ahead of the bombers. Later that day, Haiböck claimed a No. 151 Squadron Hurricane shot down near Folkestone on a combat air patrol.^[9] On 22 August, the command hierarchy in JG 26 changed. Hauptmann Adolf Galland, who had commanded III. Gruppe, was appointed Geschwaderkommodore (wing commander) of JG 26. In consequence, Schöpfel, who had led 9. Staffel until then, succeeded Galland as Gruppenkommandeur (group commander) of III. Gruppe and Haiböck was transferred to the Gruppenstab, the headquarters unit of III. Gruppe.^[10] On 28 August, the Luftwaffe attacked the airfields at Eastchurch and Rochford. In defense of this attack, the RAF dispatched 32 Hurricane fighters and 12 Boulton Paul Defiant interceptor aircraft from No. 264 Squadron. In this encounter, Haiböck was credited with the destruction of a Defiant shot down east of Canterbury.^[11]

Haiböck claimed his first aerial victory in 1941 on 17 June. That day, the RAF flew "Circus" No. 14, attacking the Kuhlmann chemical complexes at Chocques near Béthune. Defending against this attack, Haiböck claimed a Spitfire shot down near Saint-Omer which was not confirmed.^[12] On 27 September, Haiböck was again flying with 9. Staffel, then under command of Hauptmann Kurt Ruppert. Following combat with Spitfires in the vicinity of Calais, he claimed an aerial victory. That day, the RAF flew two "Circus" missions, No. 103A attacking the Amiens motor yards, and No. 103B, targeting the Mazingarbe power station.^[13]

Squadron leader

On 22 November 1941, Reichsmarschall Hermann Göring informed Galland that he would succeed Oberst Werner Mölders as General der Jagdflieger (General of the Fighter Arm), a staff position with the RLM in Berlin.^[14] In consequence of this decision, on 6 December, Schöpfel, Gruppenkommandeur of III. Gruppe was appointed Geschwaderkommodore of JG 26, and Hauptmann Josef Priller was given command of III. Gruppe, and Haiböck was appointed Staffelkapitän (squadron leader) of 1. Staffel.^[15]

On 19 August 1942, Allied forces launched Operation Jubilee, the amphibious attack on the German-occupied port of Dieppe in northern France. Defending against this attack, Haiböck led 1. Staffel of JG 26 against the Spitfire fighters protecting the landing fleet.^[16] On 28 October, Haiböck received orders that he had been transferred to Jagdgeschwader 52 (JG 52—52nd Fighter Wing) fighting on the Eastern Front. In consequence, command of 1. Staffel of JG 26 was passed on to Oberleutnant Franz Nels.^[17] The transfer was delayed and on 8 November, Haiböck claimed his last aerial victory with JG 26 when he shot down a Spitfire fighter 5 kilometers (3.1 miles) north of Gravelines.^[18]

Eastern Front

I./JG 52 insignia

On 30 December 1942, Haiböck officially succeeded Oberleutnant Friedrich Bartels as Staffelkapitän of 1. Staffel of JG 52. The Staffel was subordinated to I. Gruppe of JG 52 which was commanded by Hauptmann Helmut Bennemann.^[19] On 6 December, I. Gruppe had moved to an airfield at Rossosh where they stayed until 15 January 1943. Following further relocation, the Gruppe arrived at an airfield near Kursk on 26 January. Here on 29 January, Haiböck claimed his first aerial victories on the Eastern Front when he shot down two Ilyushin Il-2 ground-attack aircraft.^[20] On 1 February, Haiböck was shot down in a Messerschmitt Bf 109 G during a strafing attack flown 6 kilometers (3.7 miles) east of Tim. He crash landed his aircraft and returned to his unit.^[21]

On 10 February, I. Gruppe moved to Poltava where they stayed until 10 March. Here, Haiböck increased his number of aerial victories claimed to 19 by end-February.^[22] Following the German defeat at Stalingrad and Soviet advance in Voronezh–Kharkov offensive, I. Gruppe was moved to Anapa located on the northern coast of the Black Sea near the Sea of Azov on 16 May.^[23] Haiböck was awarded the German Cross in Gold (Deutsches Kreuz in Gold) on 17 October 1943.^[24]

Group commander

On 1 December 1943, Major Günther Rall, the Gruppenkommandeur of III. Gruppe of JG 52 was sent on home leave. During his absence, Haiböck temporarily was given command of the Gruppe until Rall's return on 30 January 1944.^[25] Behind Major Johannes Wiese and Leutnant Johann-Hermann Meier, Haiböck was the third most successful active fighter pilot of I. Gruppe of JG 52 at the time.^[26]

On 8 February 1944, Haiböck was transferred to take command of I. Gruppe of Jagdgeschwader 3 "Udet" (JG 3—3rd Fighter Wing) which was fighting in Defense of the Reich. He replaced Hauptmann Joachim von Wehren who had temporarily led the Gruppe after Major Klaus Quaet-Faslem was killed on 30 January.^[27][28] Command of 1. Staffel of JG 52 was passed to Oberleutnant Karl-Heinz Plücker.^[29] On 25 February, Haiböck made a forced landing in his Bf 109 G-6 (Werknummer 410377—factory number) following engine failure near Malsch, district of Karlsruhe. On the ground, he was then attacked by strafing American aircraft and seriously wounded.^[30] During his convalescence, he was awarded the Knight's Cross of the Iron Cross (Ritterkreuz des Eisernen Kreuzes) on 9 June 1944. Due to reoccurring medical complication, he remained hospitalized in a Luftwaffe hospital in Bad Ischl until the end of World War II in Europe.^[31] In consequence, command of I. Gruppe of JG 3 had been passed on to Hauptmann Helmut Mertens.^[28]

Later life and service

In 1956, Haiböck volunteered for military service in the Austrian Air Force, initially holding the rank auf Hauptmann.^[31]

Following retirement from military service in 1977, Haiböck became the president of the Austrian Aero Club.^[31] In 1986, he opposed the removal of the Alexander Löhr commemorative plaque from the Vienna the garrison church Stiftskirche. Löhr was one of the main creators of the Austrian Air Force and a convicted war criminal. The commemorative plaque had been donated by the Austrian Aero Club in 1955.^[32][33]

Haiböck, who had been living with the widow of his friend Leopold Fellerer, died on 3 July 2002 at the age of 85 in Salzburg, Austria.^[31][34]

Summary of career

Aerial victory claims

According to US historian David T. Zabecki, Haiböck was credited with 77 aerial victories.^[35] Spick also lists him with 77 aerial victories claimed in 604 combat missions. This figure includes 60 aerial victories on the Eastern Front, and further 16 victories over the Western Allies.^[36] Mathews and Foreman, authors of Luftwaffe Aces — Biographies and Victory Claims, researched the German Federal Archives and found records for 73 aerial victory claims, plus twelve further unconfirmed claims. This figure of confirmed claims includes 59 aerial victories on the Eastern Front and 14 over the Western Allies.^[37]

Victory claims were logged to a map-reference (PQ = Planquadrat), for example "PQ 73652". 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.^[38]
