The SA.342M Gazelle was a modification of the SA.341 designed specifically for the French Army. Entering service in 1984, key improvements included a more powerful engine, improved optics and avionics, and the addition of extra pylons for ordnance, which doubled the aircraft's payload capacity. These helicopters were used by France in the Gulf War as well as a number of other conflicts. SA.342Ms are still in service with France, but are gradually being phased out.

Introduced in Update 1.87 "Locked On", the SA.342M differs from the preceding SA.341F primarily by the absence of a 20 mm autocannon, but gained the ability to use two ordnance pylons instead of one. The SA.342M also received a thermal imager for improved target detection. Otherwise, it remains the same fast and agile Gazelle, capable of delivering swift attacks, though lacking in survivability.
