The 1939 S.M.79 Serie 8 differed only slightly from earlier models. The most notable external change was the relocation of the right engine exhaust pipe to the outer side of the nacelle. The fuel injection system was replaced to allow for engine boost, and the wing structure was reinforced for increased rigidity. Starting in 1938, the Reggiane, Macchi, and AUSA plants joined the SIAI factory, which had been producing the S.M.79 since 1936, in production. These four companies produced 1,218 S.M.79 aircraft by 1944, and an additional 240 were built under license in Romania.

The Italian S.M.79 Serie 8 has been in the game since the start of the Open Beta Test prior to Update 1.27 as a part of the German aircraft research tree. In terms of flight performance, armament, and suspended weaponry, the Serie 8 does not differ noticeably from its predecessor. The only difference is its ability to use engine boost, which temporarily increases engine power. Otherwise, gameplay remains the same. It is a versatile aircraft that excels at destroying ground targets. The aircraft is fairly survivable against machine gun fire but should cannot tank enemy cannons. Its defensive armament is solid, though it has numerous blind spots.
