Among the different Luftwaffe units that formed the Legion Condor, one in particular stands out for its important Naval Air contribution: the AufklArungsstaffel See/88 (AS./88 or the Maritime Reconnaissance Squadron), although it was also officially designated the Seefliegerstaffel AS./88 or Naval Air Squadron AS./88. AS./88 Squadron employed the following aircraft during the Spanish campaign: Heinkel He 59 bomber, torpedo and reconnaissance seaplanes; He 60 close reconnaissance/bomber seaplanes; He 115 A-0 reconnaissance/torpedo seaplanes; and float-fitted Junkers Ju 52s. Presented here are previously unpublished aspects regarding the operations and war service of both the personnel and aircraft of AS./88, which, during a period of three years, participated directly in the Spanish Civil War of 1936-1939 on the Nationalist side.
