Ernst Süß (31 August 1912 – 20 December 1943) was a Luftwaffe fighter ace and recipient of the Knight's Cross of the Iron Cross during World War II. During his career he was credited with 68 aerial victories. Career Süß was born on 31 August 1912 in Possessern, at the time in East Prussia, province of the Kingdom of Prussia within the German Empire, present-day Pozezdrze in northern Poland. As a reserve pilot, he was appointed to join 9./Jagdgeschwader 52 (JG 52—52nd Fighter Wing) as an Unteroffizier. With this unit he participated in the Battle of France and the Battle of Britain, without achieving any victory confirmed in this period. The rise of General Ion Antonescu in Romania in 1940 led to a reorganization of his country's armed forces. In this, he was supported by a military mission from Germany, the Luftwaffenmission Rumänien (Luftwaffe Mission Romania) under the command of Generalleutnant (equivalent to major general) Wilhelm Speidel. III. Gruppe of JG 52 was transferred to Bucharest in mid-October and temporarily renamed I. Gruppe of Jagdgeschwader 28 (JG 28—28th Fighter Wing) until 4 January 1941. Its primary task was to train Romanian Air Force personnel. Here, Süß joined the trio of Hermann Graf, Alfred Grislawski and Heinrich Füllgrabe. Later, Leopold Steinbatz and Edmund Roßmann joined as well. War against the Soviet Union Following its brief deployment in the Balkan Campaign, III. Gruppe was back in Bucharest by mid-June. There, the unit was again subordinated to the Luftwaffenmission Rumänien and reequipped with the new, more powerful Bf 109F-4 model. On 21 June, the Gruppe was ordered to Mizil in preparation of Operation Barbarossa, the German invasion of the Soviet Union. Its primary objective was to provide fighter protection for the oil fields and refineries at Ploiești. Prior to the invasion, Major Gotthard Handrick was replaced by Major Albert Blumensaat as commander of III. Gruppe. Blumensaat was then replaced by Hauptmann Hubertus von Bonin on 1 October. At the time, von Bonin was still in convalescence so that Hauptmann Franz Höring, the commander of 9. Staffel, was also made the acting Gruppenkommandeur (group commander). In the months following the beginning of Operation Barbarossa, the 9./JG 52, later dubbed the Karaya Quartet, became one of the most successful units of the Luftwaffe. Süß flew alongside Graf, Grislawski and Füllgrabe. He claimed his first victory on 8 August 1941 and in the next twelve months,
