The Fokker B series were a reconnaissance flying boat built in the Netherlands.

It was a conventional biplane flying boat design, with staggered sesquiplane wings braced by struts arranged as a Warren truss.

The engine was mounted pusher-wise on the top wing.

The duralumin hull featured three open cockpits – one at the nose for a gunner, one in front of the lower wing for the pilot and engineer and one behind the wings for another gunner.
