| + | Due to its relatively low battle rating, the three-engined S.M.79 enjoys a relatively high speed for a bomber against most of the lower ranked opposition it faces. This aids its survivability, particularly in a shallow dive. Unfortunately, it is rather lacking in bombload options compared to the He 111s and Ju 88s and also has rather poor defensive fire arcs. Unlike the German bombers, however, it is armed with 12.7 mm Breda-SAFAT machine guns which can pack quite a punch against the flimsier aircraft it faces. The pilot also controls a fixed forward-firing 12.7 mm Breda, which is otherwise uncovered by any defensive armament. This gun can be useful for strafing light vehicles and trucks that will be encountered frequently in low-rank battles and can be used to shoot down other aircraft. It is somewhat more manoeuvrable than the He 111 H-3, but the Sparviero is by no means a fighter and will rapidly lose energy in turns. With the ability to carry 500 kg bombs, the S.M.79 can use these to more easily take out pillboxes and heavier tanks, although this reduces the total bombload to only 1,000 kg as opposed to 1,250 kg with 250 kg bombs. | ||

Description
The ▀S.M.79 Sparviero bis/N (1942) is a gift rank II German bomber with a battle rating of 2.7 (AB) and 2.3 (RB/SB). Though initially in the game pre-1.27, this plane was removed upon Update 1.37 due to redundancy.

The S.M.79 bis/N (Germany) is armed with:
- 1 x 12.7 mm Breda-SAFAT machine gun, dorsal-mounted (350 rpg)
Suspended armament
The S.M.79 bis/N (Germany) can be outfitted with the following ordnance:
- 12 x 50 kg GP 50 bombs (600 kg total)
- 12 x 100 kg GP 100T bombs (1,200 kg total)
- 5 x 250 kg GP 250 bombs (1,250 kg total)

- 2 x 500 kg GP 500 bombs (1,000 kg total)
Defensive armament
2 х Turret12.7 mm Breda-SAFAT machine gun
Ammunition500 rounds
Fire rate701 shots/min
2 х Turret7.7 mm Lewis machine gun
Ammunition485 rounds
Fire rate551 shots/min
The S.M.79 bis/N (Germany) is defended by:
- 1 x 12.7 mm Breda-SAFAT machine gun, dorsal turret (500 rpg)
- 1 x 12.7 mm Breda-SAFAT machine gun, ventral turret (500 rpg)
- 1 x 7.7 mm Lewis machine gun, 2 x beam turrets (485 rpg)
Usage in battles
Due to its relatively low battle rating, the three-engined S.M.79 enjoys a relatively high speed for a bomber against most of the lower ranked opposition it faces. This aids its survivability, particularly in a shallow dive. Unfortunately, it is rather lacking in bombload options compared to the He 111s and Ju 88s and also has rather poor defensive fire arcs. Unlike the German bombers, however, it is armed with 12.7 mm Breda-SAFAT machine guns which can pack quite a punch against the flimsier aircraft it faces. The pilot also controls a fixed forward-firing 12.7 mm Breda, which is otherwise uncovered by any defensive armament. This gun can be useful for strafing light vehicles and trucks that will be encountered frequently in low-rank battles and can be used to shoot down other aircraft. It is somewhat more manoeuvrable than the He 111 H-3, but the Sparviero is by no means a fighter and will rapidly lose energy in turns. With the ability to carry 500 kg bombs, the S.M.79 can use these to more easily take out pillboxes and heavier tanks, although this reduces the total bombload to only 1,000 kg as opposed to 1,250 kg with 250 kg bombs.
