Line-up of Turkish Air Force’s Heinkel He 111F-1 perhaps at Eskisehir, HQ of the Birinci Hava Tugayi (1st Air Brigade). The Turkey, already in good relations with the Germany, purchased 24 exemplars of this German bomber, one of the first version with stepped nose, delivered from 1937 and employed until 1944. On 1939 the Turkish Air Force’s He 111F-1 were in service with four Squadron (Tayyare Bolugu) of the 1st Air Regiment (1.
