The Sablatnig SF-1 was a reconnaissance seaplane built in Germany during the First World War.[1]


It was a conventional two-bay biplane with staggered wings of unequal span and a fuselage of particularly sleek design.[2] The pilot and observer sat in open cockpits in tandem, and the undercarriage consisted of twin pontoons braced to the underside of the fuselage and to wings.[2]

Operational history[edit]

Sablatnig delivered the SF-1 prototype to the SVK (Seeflugzeug Versuchs Kommando – "Seaplane Testing Command") in October 1915 under the naval serial number 490.[2] It was finally accepted into active naval service a full two years later, in October 1917.[3] Although accepted for service with the Imperial German Navy, only the prototype was built, and no production order was forthcoming.[2][3]
