In June 1944, JG 2 and JG 26 was to form the nucleus of the 5. "Jagddivision" (5th Fighter Division) in the II. "Jagdkorps" (Fighter Corps). The fighter forces expected an invasion in the Pas de Calais, where they were based. The wing had replaced its losses and was in a much improved condition from previous months. I. and II. "Gruppe" were equipped entirely with the Fw 190 A-8, which retained powerful armament, a further fuel tank to improve ranger, and engine modifications, such the GM-1 for improved high-altitude performance. III. "Gruppe" retained the ageing Bf 109 G-6, which was an effective dogfighter, but lacked the speed to initiate or escape combat—experienced pilots could use its turn-climb qualities but inexperienced pilots proved easy targets in this type. On 6 June the Normandy landings began. "Geschwaderkommodore" Priller and his wingman were the only two pilots to attack the beaches; in this case Sword Beach. The following day, all three "gruppen" flew strafing attacks against Allied infantry from "dawn to dusk". III. "Gruppe" arrived at Guyancourt and Villacoublay, the two best equipped airfields in the region. II. "Gruppe" flew to Cormeilles. III./JG 54 reinforced JG 26. The unit came under the administrative control of the wing but was never formally attached. From 3 to 7 June JG 26 claimed 12 confirmed victories against five killed and two wounded. JG 26's pilots were given confirmed credit for 50 destroyed and five probably destroyed in June over Normandy—many more claims were made but it is unknown whether they were granted to pilots. The known cost of the fighting for the month was 32 pilots killed, 21 wounded and one captured.
