Development

The HB.5 (MB-10) originally started development as an open-sea reconnaissance/bombing flying-boat, but it was completed as a 20-seat passenger transport flying-boat. Described as grotesque it had two sets of staggered biplane wings with an unusual X-type bracing and a biplane tail with triple fins and rudders. Powered by four Salmson 9Z radial engines that were located in tandem pairs in line with the third mainplane. The H-5 had a conventional fuselage on a three-ply mahogany boat hull, which had 24 watertight compartments. The H-5 was tested from the St Raphael naval air station in 1922 and proved to be stable with little vibration. After a few test flights the H-5 was accidentally damaged and development was abandoned. Besson H-5 aircraft 1
