The Fokker B.II was a prototype sesquiplane shipboard reconnaissance flying boat built in the Netherlands in 1923.

Development

[edit]

It was a conventional flying boat with a duralumin hull and sesquiplane wings braced with N-struts. The tractor configuration engine was mounted on the leading edge of the upper wing driving a four-bladed propeller. Open cockpits were provided for the crew under the upper wing and in a dorsal position amidships.

The Royal Dutch Navy tested the prototype, but no production orders followed.
