At Stolp-Reitz, JG 54 upgraded their aircraft to the Bf 109 F-2. For the next four weeks, the pilots familiarized themselves with the new aircraft before on 15 June, III. Gruppe was ordered to Blumenfeld in East Prussia, present-day Karczarningken in the Kaliningrad Oblast, in preparation for Operation Barbarossa, the invasion of the Soviet Union. During the upcoming invasion, JG 54 would be deployed in the area of Army Group North, was subordinated to I.

In late May 1943 after a tour as an instructor, Kempf was posted to 11. Staffel of JG 54 which was based on the Western Front in defense of the Reich. 11. Staffel of JG 54 had its origin from 11. Staffel of Jagdgeschwader 26 "Schlageter". In January 1943, the Luftwaffe had planned to move JG 26 to the Eastern Front in exchange JG 54 which supported Army Group North. In order to keep up operations, the exchange was planned by rotating each Gruppe by Gruppe and every Staffel by Staffel. In this context, 11. Staffel of JG 54 was to be integrated into II. Gruppe of JG 54. On 22 May, 11. Staffel of JG 54 was ordered to Nordholz Airfield where it was subordinated to III. Gruppe of JG 26.

After the Allies launched Operation Overlord, the invasion of Normandy on 6 June 1944, Luftflotte Reich sent additional units to the invasion front. By 8 June, Jagdgeschwader 1, Jagdgeschwader 3, Jagdgeschwader 11 and III. Gruppe of JG 54 had arrived in France and were subordinated to Fliegerkorps II. III. Gruppe of JG 26 was based at Villacoublay Airfield. On 7 June, Kempf claimed the destruction of two Republic P-47 Thunderbolt fighter east of Dreux.
On 3 September, JG 26 retreated from Belgium with Geschwaderstab and I. Gruppe headed for Krefeld Airfield, II. Gruppe to Kirchhellen, now part of Bottrop, and III. Gruppe to München Gladbach. At Grimbergen Airfield, 2. Staffel was last to take off and immediately came under attack of six to eight North American P-51 Mustang fighters from the 38th Fighter Squadron of the 55th Fighter Group. In this attack, four Focke-Wulf Fw 190 fighters of 2. Staffel were shot down, including Kempf who was killed in action. His Fw 190 A-8 crashed near Baal.

Summary of career

Aerial victory claims

According to US historian David T. Zabecki, Kempf was credited with 65 aerial victories. Spick also lists him with 65 aerial victories claimed in 445 combat missions. Of this figure, 49 aerial victories were claimed on the Eastern Front and 16 over the Western Allies, including two four-engine bombers. Mathews and Foreman, authors of Luftwaffe Aces — Biographies and Victory Claims, researched the German Federal Archives and found records for 64 aerial victory claims. This figure includes 49 aerial victories on the Eastern Front and another 15 on the Western Front, including three four-engined bombers.
Victory claims were logged to a map-reference, for example "PQ 29173". The Luftwaffe grid map 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. These sectors were then subdivided into 36 smaller units to give a location area in size.
