The Blériot 195 was a large low-wing cantilever monoplane designed for use on mail flights across the North Atlantic. It was powered by four 1000NaN0 Hispano-Suiza 6Mb inline piston engines, which were mounted in tandem pairs above the wing on a complex of struts. Designated the 195/2 landplane, it first flew on 9 March 1929. By the end of 1929, it had been re-designated the 195/3 and test flown with twin floats. It was re-designated again as the 195/4 in early 1930, when it was fitted with 2300NaN0 Gnome-Rhone Titan engines. It was put forward to meet a requirement for a seaplane to operate a mail service between Marseilles and Algiers, but in the end none of the designs submitted were accepted and the 195 was placed into storage.
In April 1931 it was brought out of storage and modified to be a landplane and designated the 195/6; it was then tested by Air Union as a cargo aircraft. It did not gain a certificate of airworthiness as a cargo carrier and was withdrawn from use.
