a Figures are debated. Griehl cites additions of Chief engineer Pichon's list. This indicates 5,930 produced. Griehl points out this number may include all machines, even those that were incomplete or unassembled. Junkers records give only 5,126 aircraft delivered to the Luftwaffe.[1]
b The first of Germany's allies to receive Stukas was Italy. Regia Aeronautica received a delivery of 46 Ju 87 D-2 and D-3 dive bombers and some Ju 87 R-2s.[2] Bulgaria received 12 Ju 87 R-2 and R-4s and 40 Ju 87 D-5s.[3] Japan received the Ju 87 A-1 (called a Ju 87 K-1). The Croats received a number of Ju 87s, delivered to the Lucko bomber unit in January 1944. The Romanians received just 90 Ju 87 D-3 and D-5s.[4] Hungary received 33/34 Ju 87 D-3/D-5s and 11/12 B-1 and B-2s.[5] The Slovaks received unknown numbers of Ju 87s. After the war it is claimed five Ju 87 D-5s, registrations OK-XAA - OK-XAE, were operated by the Czechs after the war as "B-37" registration OK-KAC.[6]
c Werknummer (W.Nr) means "Works Number" of the factory. The number can usually be found on the vertical stabiliser of all German military aircraft of the Second World War.
