It was a twin-engined biplane, a final development in the family of designs that began with the Blériot 115.

Two were built for Air Union to replace the Farman Goliath on their Paris–London route and were christened Leonardo da Vinci and Octave Chanute.

The airline found that it preferred the Lioré et Olivier LeO 21s that it had ordered alongside this aircraft, meaning that no further examples were produced.

At one point, plans were made to build a second 175 for Paul Codos to make a long-distance flight from Paris to Tokyo, but this did not eventuate.
