The programme was assisted by the recovery of a partial V-1 by Soviet forces at the Blizna test range in Poland.
During the war units of Polish Armia Krajowa (AK) and BCh (Polish Peasants' Battalions) operating in this area discovered testing sites for the German V-1 and V-2 rockets in the nearby towns of Blizna/Pustkow.
