It was initially planned to use these planes as dive bombers in the 1st flight of LeLv 48, which began to receive its aircraft in July 1942, but during the training it was found out that this caused too much strain for the engines. Thus, the role of Pe-2s was changed to fly long-range photographic and visual reconnaissance missions for the Army General Headquarters. These sorties began in late 1942, and were often flown with two 250 kg (551 lb) bombs for harassment bombing and in order to cover the true purpose of missions.
