Design and development

The H-3 was designed as a civil touring flying boat and had single-bay equal-span wings and room for two in a side-by-side configuration cockpit, it was fitted with dual-controls.[1] Initially powered by a 45 kW (60 hp) le Rhône 9Z rotary, the H-3 was found to be under-powered and re-engined with a 97 kW (130 hp) Clerget 9B rotary, (from Société Clerget-Blin et Cie), driving a tractor propeller.[1] The aircraft did not enter production and the sole H-3 was re-designated MB-12 in 1922 when it was modified with an enlarged central wing.[1]
