The RWD-9 was designed specially for the purpose of competing in the IVth Challenge de Tourisme International to be held in Warsaw during August–September 1934 .

It was constructed by Stanisław Rogalski and Jerzy Drzewiecki of the RWD team in the DWL workshops in Warsaw.

To meet new contest regulations, the new plane was designed as four-seater, with increased mass and engine power and yet better STOL capabilities.

In 1935 two of them (SP-DRA, -DRB) were sold to Spain, and the third SP-DRE to French institute CEMA (Centre d'Essais de Matériels Aériens [fr], Aerial Equipments Test Center), in Villacoublay (markings: F-AKHE).

On July 16, 1936, RWD 9 SP-DRC crashed to the Baltic Sea due to low flying, killing crew, with Polish General Gustaw Orlicz-Dreszer aboard.

The cabin was enclosed with four places in two rows, with two doors, and the cockpit fitted with double controls for pilot and co-pilot.
