The Sablatnig SF-5 was a reconnaissance seaplane produced in Germany during the First World War.
[1] 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.
[2][3] 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).
[2] 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.
[2] A single SF-5 was fitted with wheeled undercarriage salvaged from another aircraft.
