From 1943 this type was used in small numbers by high-altitude squadrons and by Reserve Fighter Group West. Next came the Me 109 G-3, which was the second ‘Gustav’ to have a pressurized cockpit. Series production of the Me 109 G-2 without the pressurized cabin began in parallel production of the Me 109 G-1, and G-2 aircraft were supplied in the summer of 1942 to, among others, Jagdgeschwader JG 2, 3, 5,27, 62, 53, 54 and 66, as well as different reconnaissance groups. At the end of 1942 they first saw action in the Mediterranean. The aircraft went to II/JG1, and later a few went to II/JG26 as equipment for high-altitude squadrons. The Bf 109 G-1 was conceived as a single-seat high-altitude fighter with a pressurized cabin. As early as the autumn of 1941 a zero-series of several models was tested with the DB 601 E engine.
