Karl Gratz

Gratz was released from captivity in 1949, joined the Bundeswehr and served in Jagdbombergeschwader 33 (JaBoG 33—Fighter-Bomber Wing 33). He retired in 1970 holding the rank of Oberstleutnant (lieutenant colonel). Gratz died on 14 March 2002 in Leck.

Post-war, his military service in the Bundeswehr saw him promoted to Oberstleutnant. Gratz served in Jagdbombergeschwader 33 (JaBoG 33—Fighter-Bomber Wing 33) flying the Republic F-84F Thunderstreak then under the command of Walter Krupinski. JaBoG 33 was transferred to the Turkish base at Bandırma for shooting and bombing training with live ammunition from 25 May to 31 August 1959. During one of the practice flights Gratz was nearly shot down by his wingman Leutnant Dietrich Schultz-Sembten. Schultz-Sembten had mistakenly fired all of his rockets prematurely during the attack run. After the landing, Gratz is quoted with having said: "Schultz-Sembten, you must have gone mad! I have to say one thing, you idiot: If you had hit me, I would have outmaneuvered you and shot you down."

In March 1944, Gratz returned to JG 52. That month, Gratz was credited with his 100th aerial victory. He was the 64th Luftwaffe pilot to achieve the century mark. On 1 April 1945, Gratz was appointed Staffelkapitän (squadron leader) of 10. Staffel of JG 52. He succeeded Leutnant Viktor Petermann who was transferred. 10. Staffel was subordinated to III. Gruppe of JG 52 and headed by Major Adolf Borchers. In the last weeks of the war, Gratz was particularly successful and claimed 18 victories. After the surrender he was delivered by U.S. military to the Soviet authorities and remained in captivity until 1949.

After a spell instructing, Gratz was posted in March 1943 to 11. Staffel (11th squadron) of Jagdgeschwader 2 "Richthofen" (JG 2—2nd Fighter Wing) on the English channel front. The 11. Staffel was an additional 4th squadron of I. Gruppe of JG 2 which was based at Triquerville and equipped with the Bf 109 G-3. On 1 October 1943, the squadron was renumbered and from then on was known as 4. Staffel of JG 2.

Gratz received the German Cross in Gold (Deutsches Kreuz in Gold) on 8 June 1943. On 16 August, the Eighth Air Force of the United States Army Air Forces (USAAF) targeted the Le Bourget airfield near Paris with a large formation of Boeing B-17 Flying Fortress escorted by a number of Republic P-47 Thunderbolt escort fighters. In defense of this attack, I. Gruppe of JG 2 claimed three B-17s and one P-47 shot down for the loss of five pilots killed in action. In this encounter, Gratz was credited with the destruction of one B-17 shot down 9 km (5.6 mi) southeast of Brétigny.

In late 1941, Gratz was posted to Jagdgeschwader 52 (JG 52—8th squadron of the 52nd Fighter Wing) which at the time was fighting on the Eastern Front. He claimed his first aerial victory on 15 February 1942. On 1 July 1942, he was awarded the Knight's Cross of the Iron Cross following his 54th aerial victory. He then served as a fighter pilot instructor and was posted to Jagdgeschwader 2 "Richthofen" (JG 2—2nd Fighter Wing) in March 1943. Back on the Easter Front in 1944, he claimed his 100th aerial victory in March/April 1944. At the end of World War II, he served as Staffelkapitän (squadron leader) of 10. Staffel (10th squadron) of JG 52. He surrendered to United States Army forces and was turned over to the Red Army.

On 20 May, III. Gruppe moved to an airfield at Barwenkowa, approximately 40 kilometres (25 miles) south-southwest of Izium. By the end of May 24, Soviet forces opposite Kharkov had been surrounded by German formations, over the next days, Soviet forces attempt to break the encirclement. During this combat, Gratz claimed four aerial victories on 26 May over two LaGG-3s and two MiG-1s. The next day, he added three further aerial victories to his tally over a LaGG-3 and two MiG-1s. On 29 May, his total reached 42 aerial victories when shot down an I-16 and yet another MiG-1. He received the Honor Goblet of the Luftwaffe (Ehrenpokal der Luftwaffe) on 8 June 1942.

He and Oberfeldwebel Karl Steffen received the Knight's Cross of the Iron Cross (Ritterkreuz des Eisernen Kreuzes) on 1 July 1942. The presentation was made by Major Hubertus von Bonin. By late 1942 29 more victories had been claimed.

"Charlie" Gratz was posted in autumn 1941 to 8. Staffel (8th squadron) of Jagdgeschwader 52 (JG 52—8th squadron of the 52nd Fighter Wing), a squadron of III. Gruppe (3rd group), on the Eastern Front. In January 1942, III. Gruppe was ordered to move from Taganrog to an airfield at Kharkov and was subordinated to IV. Fliegerkorps. At the time, the Gruppe was the only fighter unit operating on the left flank of Army Group South, covering the airspace from Belgorod in the north to the Donets Basin in the south, and was equipped with Messerschmitt Bf 109 F-4. On 18 January, Soviet forces launched the Barvenkovo–Lozovaya Offensive which created the Izium salient. On 15 February, III. Gruppe flew missions in the vicinity of Belgorod and Prokhorovka, over the front lines of the 6th Army. That day, Gratz claimed his first two aerial victories, a Mikoyan-Gurevich MiG-3 fighter which at the time was referred to as an I-61, and an Ilyushin Il-2 ground-attack aircraft.

Karl Gratz (24 January 1919 – 14 March 2002) was an Austrian-born Luftwaffe fighter pilot during World War II. As a fighter ace, he was credited with 138 aerial victories claimed in more than 900 missions. Gratz claimed the majority of his victories over the Eastern Front, and 17 over the Western Front.
