The Bf.109B-2 was powered by a 680 hp Jumo 210Ea engine (Some had the 700 hp Jumo 210G engine) with two stage supercharger and a Hamilton two bladed variable-pitch metal airscrew. Sixteen aircraft of this type were sent to Spain in the spring of 1937 to re-equip the second staffeln of Jagdgruppe 88 fighting with the Condor Legion. Later that year the 1st Staffeln would be similar equipped. In total forty five Bf.109Bs would find their way to Spain The third Staffeln of Jagdgruppe 88 would receive five Bf.109C-1 in early 1938, with a further five Bf.109D-1s being supplied later in the year to bring the squadron up to strength. The Condor Legion would also receive up to forty Bf.109E-1s in the closing months of the war in Spain, but these saw little action and would ultimately be transferred to the Post-Civil War Spanish Air Force.
