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 IIB was the bomber of the family. Compared to the previous Vautour IIA, this one added an additional crew member at the front of the aircraft in a transparent nose, tasked with acquiring the target to release the bombs. A total of 40 Vautour IIBs were built, with some being sold to Israel in 1960.

It was introduced in Update 1.73 "Vive la France". The S.O.4050 Vautour IIB acts as a bomber, as such, your main objective in air battles is to destroy enemy bases or destroy ground units to drain enemy tickets. Since it has a very good acceleration, it is one of the first to take off from the runway. When bombing, there are two main options: climbing to high altitudes and releasing the bombs from there works well but only in downtiers, since your lack of countermeasures makes it easy for enemy interceptors to attack you. The other option is rushing the enemy base, this works better and your acceleration makes it easier to be one of the first to reach the base, stay close to your team since you lack the agility or the countermeasures to avoid being hit by a missile or intercepted by a fighter.

Usage in battles

Vautour IIB has very good acceleration, after takeoff side climb to 5000 m. From there you have two options,


One way of playing the Vautour IIB is diving, rushing into a base bombing point and bombing it. Doing this can guaranteed a chance to drop a bomb at the base if the map is small enough to reach it. Following the bombing, the plane will still have a high speed due to the dive and so it can quickly withdraw back to the base to land and reload. However; this tactic doesn't work as well on larger maps where it would take a longer time to reach a base to bomb. Not to mention that doing so will sacrifice altitude and cause the Vautour to be below many enemy fighters, which the Vautour cannot defend itself due to lack of armaments.

Keeping your altitude:

The other way of using the Vautour IIB is by keeping your altitude and climbing and then using your bombsight to bomb a base. Staying at a high altitude can prove safer as it can cause the Vautour to stay atop of many enemy fighters. However, bombing can be harder due to many more variables to keep account for when using the bomb sight. Getting up to altitude at standard speed can also make reaching the base harder, and so it would take a longer time to complete a bombing run. In some cases, more well-performing fighters like the F-100s can make this tactic moot as their speed will ensure they catch up and destroy the Vautour before it has a chance to drop its payload.

Pros and cons


  • Insane acceleration
  • Climbs exceptionally well without ordnance
  • Energy retention is great
  • Airbrakes, you will need them to avoid compressing in a dive
  • Possesses a bombsight


  • Lacks the rocket payload options of the Vautour IIA
  • Compresses at high speed
  • Massive penalties in-flight performance when carrying full payloads
  • Turns like a brick
  • Roll rate is also unimpressive
  • Fragile engines; a hit to an engine will make you easy prey for enemy fighters
  • Relies heavily on team support even more than the Vautour IIA does
  • Massive target
  • No offensive armament
  • 110% will easily overheat your engines after short use
  • Lack countermeasures


The S.O.4050 Vautour IIB was developed by Sud Aviation after World War Two to meet the demand for the French Armée de l'Air. This was a challenging task, after the German occupation in France. Many aircraft design teams have scattered. France was also new to the new jet propulsion area. The requirements issued by the French government called for a jet-powered multi-role attack aircraft that can perform as a bomber, low-level attack aircraft, and an all-weather interceptor. SNCASO met those requirements with a modified version of the S.O 4000. The new plane was designated the S.O.4050 Vautour and was manufactured in three different variants. The plane would serve in the AdA for several decades before replaced the newer Dassault Mirage. The Vautour was also one of the stop-gap measures used by the AdA as a nuclear deterrent. The Vautour would later be exported to Israel and serve with the IAF to counter Egypt's IL-28 twin-engine bomber.

The IIB, which differed from the previous IIA by adding a second crew member in a transparent nose, was a dedicated bomber variant. Its prototype first flew in December 1954. In total 40 of the IIB would be built. All were sold along with all of France's Vautour IIAs to Israel in 1960.
