JG 1 was the only fighter wing assigned to Lw Bfh Mitte (later "Luftflotte Reich") in 1942. JG 1s four "gruppen" were spread from Norway to the Netherlands, on the periphery, while the only fighter units in the interior of Germany were fighter schools or small action units assigned to a particular factory or installation. JG 1s units were shared between "Jagdivision" 1 and "Jagdivision" 2. Amongst the major actions of 1942 to involve JG 1 was Operation Donnerkeil and Operation Jubilee in February and August 1942. In Donnerkeil, JG 1 claimed seven RAF bombers near Texel, four falling to 5./JG 1.
