The Alpha Jet A entered service with the Royal Thai Air Force in the late 1990s as part of a deal to acquire 55 ex-German aircraft from Fürstenfeldbruck Air Base. It was initially planned that the ferry flights and overhaul would be conducted in Thailand, with the assistance of Fairchild Dornier, which would reduce future costs by creating a local maintenance base. However, under pressure from the United States, only 25 Alpha Jets were ultimately acquired, and the maintenance was carried out in Germany, preventing Thailand from developing its own maintenance infrastructure. In September 2000, the Alpha Jet A entered service with the 231st Squadron of the 23rd Wing at RTAFB Udon Thani. Approximately 20 aircraft were kept airworthy, while the remaining units served as sources of spare parts. Between 2004 and 2007, the remaining aircraft were upgraded with chaff/flare dispensers and modified hardpoints.

Introduced in Update "Storm Warning", the Alpha Jet A is a light, compact, and maneuverable aircraft with a wide range of suspended weapons. It is particularly effective in combined arms combat but is also capable of performing well in air combat modes due to its small size, excellent handling, and effective cannon. The Alpha Jet A has no guided weapons; however, the presence of a ballistic computer for bombs and rockets allows for the accurate use of its unguided ordnance. The Alpha Jet A is also equipped with a flare/chaff dispenser, which increases survivability against heat-seeking missiles. Weaknesses include the lack of a RWR and poor acceleration at speeds above 700 km/h.
