H-241 The initial four-engined long-range heavy-weight variant of the H-24. The hull was almost exclusively made of anodised Duralumin, for corrosion resistance. Although construction began before the H.242, the sole H.241 was completed later, but did not enter production. H-242 Initial production. Powered by four Gnome-Rhône 7Kd Titan Major radial engines. Two were built for Air France and delivered in December 1933 and February 1934. They could carry ten passengers. H-242/1 Revised production version, with a modified engine installation. Twelve were built for Air France and delivered between March 1935 and May 1937, carrying twelve passengers. Most H.242/1s were fitted with wide chord NACA cowlings over the front engine only, but some aircraft were fitted with narrow chord Townend rings around the front engine. H-243 an un-built projected version for the French navy with enlarged hull. H-244 A projected high-speed inter-continental flying boat for Air Union, abandoned when Air Union was absorbed by Air France. H-24.01 First prototype.
