High Quality Content by WIKIPEDIA articles! The Sablatnig SF-5 was a reconnaissance seaplane produced in Germany during the First World War. Designed to meet a specification by the Imperial German Navy for a higher-powered replacement for the Sablatnig SF-2s then in service, the SF-5 was a very similar aircraft other than in its choice of engine. The first batch (serials 968–987) were delivered between January and May 1917, built in the Navy`s HFT classification (unarmed reconnaissance aircraft equipped with wireless transmitter and receiver). They were followed by two further batches (1224–1233 and 1352–1371) between July and September.LVG built the type under licence as a trainer aircraft without any radio equipment, delivering 20 aircraft (1017–1036 and 1214–1223) during the second half of 1917.LFG produced the type in the BFT category (unarmed reconnaissance aircraft equipped with wireless transmitter but not receiver), building ten examples (1459–1468) between September 1917 and February 1918. Sablatnig also produced a single BFT-configured aircraft in February 1918.
