The CAMS 55 was a reconnaissance flying boat built in France in the late 1920s which equipped the French Navy throughout the 1930s.
The bow also incorporated an observation balcony with windows sloped to afford a good downward view.
Eventually, 15 escadrilles were equipped with CAMS 55s of various subtypes, replacing the Latham 47 in some units, and in turn being relegated to secondary duties when the Breguet Bizerte became available in 1936.
Twenty-nine remained in service at the outbreak of World War II, with the last examples serving with Escadrille 20S in Tahiti until January 1941.
