The S.O.4050 Vautour II was a French project with the intention of creating a capable multirole twin-engined aircraft that could be used as a frontline bomber, close air support, or as an all-weather interceptor. With different variants developed, each one to fulfil a separate task, the Vautour IIA was the one designed for the CAS role, and the first one to be developed. The Vautour IIA was built between 1956 and 1959 and with a single crewmember, the pilot. Being the first variant of the Vautour II, some things needed improvements, like the SNECMA ATAR 101E3 engines, that were improved to the E5 version in the other variants, with access to more thrust and WEP.

It was introduced in Update 1.73 "Vive la France". The S.O.4050 Vautour IIA is a very fast ground attack aircraft; it works very well as a bomber, being fast and relatively agile for a subsonic bomber. It uses the SNECMA ATAR 101E3 engine, which does not have access to WEP like the engines on the other Vautour II variants. However, it is still very fast, and has enough payload to destroy a full base and a half in air realistic battles. For ground battles, it lacks any kind of ballistics computer, and the mediocre agility makes harder dropping bombs at moving targets, so, using the SNEB type 23 rockets while also carrying a small amount of bombs in the bomb bay is recommended.
