The '''FBA 21''' and '''23''' were small [[flying boat]] [[airliner]]s built in [[France]] in the mid-1920s. Their development was an attempt by FBA to develop a commercial version of their [[FBA 19]] [[bomber]] which had failed to attract orders from military buyers. Retaining the same basic design as their predecessor, the Model 21 added an enclosed cabin for four passengers. Unfortunately for FBA, they aroused as little interest as their military counterparts, and only a handful were built in a number of slight variations, including one example of a dedicated [[mail plane]].

In 1926, [[Maurice Noguès]] had recently joined [[Compagnie des Messageries Transaériennes]] (CMT) and was looking for an aircraft to use on a new [[Paris]]-[[Saigon]] route. Accordingly, FBA rebuilt one of the Type 21s to optimise it for long-distance flight and redesignated it the '''Type 23'''. The W-12 engine was replaced with a [[Radial engine|radial]], and the aircraft was generally lightened to allow for greater fuel capacity. Painted bright orange, the aircraft was extensively tested throughout late 1926, and apart from an early mishap while being flown by Noguès himself, flew over {{convert|6,000|km|mi|abbr=on}} without incident. Nevertheless, the CMT contract went to the [[CAMS 53]] and no further examples of the type were built.
