77 claimed some 79 victories, for 6 pilots killed, before leaving in November 1940 for defence duties in Brest, France. In May 1941 II. and III./JG 77 were used in support of the invasion of Greece and the paratroop assault on Crete. Following the operations in Crete, JG 77 was withdrawn to Romania; III. Gruppe was converted to the new Bf 109F. As Operation Barbarossa, the invasion of the Soviet Union, started on 22 June 1941, II. and III. Gruppe plus Stab supported the advance East as part of Army Group South, while I. Gruppe served on the Finnish front. The Jagdgeschwader scored quickly. On 25 June, Walter Hoeckner of 6./JG 77 shot down 8 of 10 Tupolev SB claimed by III./JG 77, while on 26 June, Oblt. Kurt Ubben shot down 4 SB and Ofw. Reinhold Schmetzer shot down 5 SB. In the period from 22 June to December 1941 the unit, and its attachment I.(J)/LG 2, destroyed 1,166 Soviet aircraft, in return for 52 losses in aerial combat and two aircraft on the ground. I. Gruppe, which was still based in Norway, was reorganized into I. Gruppe/JG 5 in January 1942, and the entire JG 77 (with a newly created I. Gruppe) was then transferred south to the Mediterranean area from June - December 1942. JG 77 saw extensive action against the Desert Air Force fighter-bombers. Total Allied air superiority led to the various JG 77 bases in Tunisia coming under constant air attack, and a large number of Bf 109's were written off on the ground. Following the death in late March 1943 of the unit's commander Joachim Müncheberg during a mid-air collision during combat Oberstleutnant Johannes Steinhoff was appointed commander of the unit. While I. and II./JG 77 returned to Germany to re-equip, III./JG 77 remained in Italy, based at Foggia, north-east of Naples and flying sorties into Sardinia and Sicily. In mid-June, I./JG 77 flew into Sciacca on Sicily. The Geschwader, as part of 2nd Air Corps, was then stationed in Italy and Sicily. During the rest of 1943 and 1944 JG 77 was stationed on the Southern Front, mainly in the Balkans, Sardinia and Italy, but also in Romania. Luftwaffe II.Gruppe of JG 77 operated with requisitioned Macchi C.205Vs, for two months, from October until the end of 1943, in December, when the German unit was re-equipped with new Bf 109s.
