The Sablatnig SF-1 was a reconnaissance seaplane built in Germany during the First World War.
It was a conventional two-bay biplane with staggered wings of unequal span and a fuselage of particularly sleek design. 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.
Sablatnig delivered the SF-1 prototype to the SVK (Seeflugzeug Versuchs Kommando – "Seaplane Testing Command") in October 1915 under the naval serial number 490. It was finally accepted into active naval service a full two years later, in October 1917. Although accepted for service with the Imperial German Navy, only the prototype was built, and no production order was forthcoming.
