Sablatnig SF-8

The Sablatnig SF-8 was a training seaplane produced in Germany during the First World War.[1] While Sablatnig's previous designs for the Imperial German Navy had often seen service as trainers, the SF-8 was purpose-built for this role, at Dr Sablatnig's suggestion.[2] The SF-8 was similar to the firm's earlier designs: a conventional two-bay biplane with staggered wings of unequal span, with open cockpits in tandem.[2]

Operational history

The Navy ordered three machines for evaluation (serials 2020–2022) in 1917, which were delivered on 17 January the following year.[3] After evaluation at Warnemünde proved favourable, the Navy ordered the type into production, placing an order for 30 machines and allocating serial numbers 6001–6030 to the batch.[2] It is unclear how many of these were produced or delivered before the end of the war.[2]
