A pair of triplanes based on the Nieuport 17 were constructed for testing purposes, one for the French and the other for the British. The narrow chord wings were staggered in an unusual manner, placing the middle wing furthest forward and the top wing furthest aft. No subsequent orders came as a result of these tests. Nieuport later trialled the same layout on the Nieuport 17bis, which was tested by the British Royal Flying Corps and Royal Naval Air Service as well, however this also remained a prototype. During flight testing, both types demonstrated favourable climbing characteristics, but were also found to be relatively tail-heavy.
