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. Initially powered by a 60 hp le Rhône 9Z rotary, the H-3 was found to be under-powered and re-engined with a 130 hp Clerget 9B rotary, (from Société Clerget-Blin et Cie), driving a tractor propeller. 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.
