CAMS 46

The CAMS 46 was a flying boat trainer aircraft built in France in the mid-1920s, essentially an updated version of the CAMS 30 that had flown in 1922. While retaining that aircraft's basic form, CAMS offered the French Navy two new versions with aerodynamic refinements over the earlier aircraft: the CAMS 46 E primary trainer, and the CAMS 46 ET intermediate trainer. Only the latter was selected for production and was built in quantity to supply one escadrille at the Naval training station at Hourtin.
