SM.79-III
Improved extended range torpedo bomber introduced late 1942, it was not available in significant numbers until mid-1943. Known also as SM.79bis, SM.79GA, or SM.579.
Powered by AR.128 engines of approximately 746 kW (1,000 hp) each, giving increased performance (speed increased to 475 km/h/295 mph, and climb to 5,000 m/16,400 ft in 16 minutes 7 sec). Ventral nacelle deleted. 1,000 L (260 US gal) fuel tank mounted in the bomb bay.
The forward machine gun was retained, with its flash protection, probably as an anti-ship weapon.

SM.79B
Twin-engine export version powered by less reliable Fiat A.80 engines and with a glazed nose for improved bomb-aiming. More economical but slower (420 km/h/260 mph and 21.45 minutes to 5,000 m/16,400 ft) than the standard SM.79, but weighed 6,600/10,100 kg (14,551/22,267 lb, around 500 kg/1,100 lb less than the basic SM.79), was longer (16.22 m/53.22 ft), and had the same armament. Iraq bought five, but this version achieved little success in Italy.
