Military Operators

The SIAI-Marchetti S.211 (later Aermacchi S-211) is a turbofan-powered military trainer aircraft designed and originally marketed by SIAI-Marchetti. Some 60 aircraft have been sold to air forces around the world. Aermacchi bought the production rights in 1997.

Since the 1990s, the Philippine Air Force has been using the S-211 as a Trainer with secondary Attack Capability. These were redesignated as AS-211s and nicknamed as "Warriors".With the retirement of the F-5 fighters in 2005, the additional task of air defense was assigned to it as well. Because of this, the Philippine Air Force initiated some improvements to the AS-211s to improve its combat capability through a series of programs and innovations.
