Spain (Ejército del Aire). Dornier Do 17
Due to the vulnerability of the Junkers Ju 52 to the FARE Polikarpov I-15 and I-16 fighters, the Legion Condor (German expeditionary force in the Spanish Civil War) was equipped with Heinkel He 111 (nicknamed “Pedros”) and Dornier Do 17 bombers (“Pablos”). The Dornier Do 17 were fast and agile and highly appreciated, but vulnerable to combat damage. They were Do 17E-1 bombers and Do 17F-1 for reconnaissance. Where nicknamed “chivatos” (mean snitches, by the Republicans) and "”Bacalaos” (cod) for their crushed appearance. In 1938, additional Do 17Ps arrived to replace losses. In 1938 the surviving Dornier were transferred to the groups 7-G-27 and 8-G-27 of the Ejército del Aire. They flew until 1951.
