The M.C.99 was designed by Mario Castoldi as a military flying boat, resembling the earlier commercial M.C.94 and was a wooden twin-engined shoulder-wing cantilever monoplane.^[1] Constructed mainly of wood, it was a high-wing cantilever monoplane flying boat.^[1] With a crew of five, it had an enclosed cabin and had defensive gun positions in the bow, amidships and in the tail.^[1] The prototype and only M.C.99 was powered by two 890 kW (1,190 hp) Isotta Fraschini Asso XI R.2C.15 engines, strut-mounted above the wings.^[1] Briefly flown in 1937 it did not enter production.^[1]
