Bob joined the Luftwaffe in 1936, at the rank of a Fahnenjunker, and began his flight training on 1 June 1937.
World War II
In 1939, prior to the Invasion of Poland, Bob was transferred to the newly formed 3./Jagdgeschwader 21 , which was redesignated on 6 June 1940 into 9./Jagdgeschwader 54. It was equipped with the Bf 109 fighter, an aircraft Bob would become very familiar with over the years – flying every model except the Kurfürst. During the French campaign on 10 May 1940, Bob claimed his first victory when he shot down a Gloster Gladiator over Tongeren in Belgium. That August, he was promoted to the rank of Oberleutnant. On 10 October 1940, he was appointed Staffelkapitän of 7./JG 54 for a short period; he was soon appointed Staffelkapitän of 9./JG 54. During the Battle of Britain, 9./JG 54 was activated as a Jabo unit, targeting shipping vessels. By November 1940, Bob had recorded 19 kills, and was awarded the Knight's Cross of the Iron Cross by ReichsmarschallHermann Göring on 7 March 1941. On 21 March 1941, Bob survived, unhurt, a ditching into Cherbourg harbour with his Bü 131 training aircraft, which had suffered engine failure. After the Battle of Britain, he participated in the Balkan campaign, where he recorded his 20th and 21st victories. JG 54 was re-equipped with the new Bf 109 F and relocated to airfields in Prussia, in preparation for Operation Barbarossa, the invasion of Russia. On 23 June 1941, Hans Ekkehard Bob recorded his first victory in Russian airspace – a Tupolev SB twin-engined bomber. During this combat, his Bf 109 F-2 was hit by return fire, resulting in a forced landingbehind enemy lines. He evaded capture and returned to his unit two days later. Between 13 July and 30 October 1941, Bob made three more emergency landings due to aircraft combat damage behind enemy lines, but in each case returned to his unit. On 29 September 1942, Bob had his 50th victory, and was promoted to Hauptmann later that year. Flying on the Eastern Front ended for Hans Ekkehard Bob and III./JG 54 in February 1943, after he received orders from General der JagdfliegerAdolf Galland to change positions with elements of the then French-based JG 26. This order was later cancelled, but III. Gruppe stayed on the Western Front, separated from the rest of the 'Greenhearts', serving initially in northern Germany with Jagdgeschwader 1. On 17 April 1943, Bob recorded his 57th victory; the ramming of a USAAFBoeing B-17 bomber near Bremen with his Bf 109 G-6. He bailed out and survived the crash without injury. On 1 August, Bob was promoted to the rank of Major and was appointed Gruppenkommandeur of IV./JG 54. He returned to the Eastern Front, where he scored a further two victories. By May 1944, Bob was back at the Western Front as Gruppenkommandeur of II./Jagdgeschwader 3, based in the Normandy invasion front corridor, flying Reichsverteidigung duties. In August, he was transferred to Erprobungskommando 262 where he learned to fly the Messerschmitt Me 262. In early 1945, his experience led to his becoming a member of General der Flieger Josef Kammhuber's staff. Bob was responsible for allocating newly built Me 262's to operational units. Later, he took command of I. and II./EJG 2 and was responsible for practice and training former bomber pilots in flying the Me 262. Bob was one of the aces chosen to fly as a member of the jet fighter unit JV 44, led by Adolf Galland. In the final days of World War II, Bob was responsible for building a longer runway at Innsbruck airfield for the Me 262 jets. At the capitulation on 8 May 1945, Bob was in Kappl, a small village near Salzburg. From Kappl, he walked more than in six weeks to return to his home in Celle.
Bob returned to civilian life working as a farm labourer. In 1946, he founded his own transport company. Around this time, he met Waldemar Wübke, an old JV 44 comrade, and a friend from his time in JG 54. Bob always told Wübke's history with a smile on his face. Wübke still wore his old uniform and officer cap as he was questioned by a British officer. "Why are you wearing this old stuff?" Wübke replied, "Do I ask you if your grandma has hemorrhoids?" He never met Wübke again, and Wübke later died in the early 1950s in Argentina, the result of injuries sustained in an airliner crash. In 1956, Bob established the Celle Flying Club. From 30 September to 1 October 2000, Bob also was among the historical figures at the 60th anniversary of the Battle of Britain in Santa Monica, California. Bob had been married to his wife Christa for over 50 years. They had three children: Roland, Elmar and Delia. He also had three other children with his first wife. He died on 12 August 2013.
