Aermacchi AS-211 (No. 802) on Display with Armaments in Clark Airfield, 2012
OVERVIEW
SIAI-Marchetti first began the development of what would become the S.211 in 1976 as a new basic trainer aircraft to be offered to existing customers of the SF.260, which then first flew in 1981. Two years later, the Singapore Air Force ordered the aircraft. Then in 1990, the Philippines ordered the type which were soon redesignated as the AS.211 to reflect its secondary offensive roles aside from being just a trainer aircraft. Soon, the F-5s of the PAF were also retired and so the task of Air Defense was also then pushed into the airframe.

To accommodate this change in roles, the Philippine Air Force began a series of upgrades on the airframe starting with “Project Falcon” & “Project Falcon Uniform” which transferred some of the retired F-5 avionics (particularly the Norsight Optical Sight) to be fitted onto the AS.211 along with a low visibility paint scheme. “Project Falcon Hear” fitted the AS.211 with communications equipment from the F-5s and the fitting of a domestic belly mounted .50 cal gunpod from Aerotech Industries. Additionally, “Project Falcon Push” supposedly tried to fit the F-5s 20mm gun pod system already in service with the PAF’s OV-10 aircraft.

Somewhere along these programs, provisions for the fitting of the AIM-9B Sidewinders that were from the retired F-5s and F-8 Crusader were also said to be installed (although I couldnt confirm any of these sources; pictures during demos sometimes include the AIM-9B as presented above as possible armament however I couldnt find any pictures of them actually fitted during flight).

Provisions for GBU-49 Enhanced Paveway II Laser Guided Bombs were also fitted with the use of WiPak. Both of these provisions are both seen on aircraft no. 802 and both pictured in 2012.
S.211 in RSAF service
Meanwhile in the Republic of Singapore Air Force service, the S.211 was replaced in 2008 with the Pilatus PC-21 for its basic to advanced flight training purposes. In the PAF, the FA-50 began to replace the AS.211 for Air Defense and CAS duties, freeing the type to focus on training.
SPECIFICATIONS
While there were plenty of upgrades on the AS.211 over its lifetime, the overall airframe stayed roughly the same. SIAI-Marchetti also worked closely with the PAF even having a dedicated flight manual designating it as the S.211 PAF “Warrior”.
As the only operator of the type, the AS.211 should be reserved as part of a Philippine subtree and wherever it will be placed with the RSAF S.211 being either a premium or squadron vehicle without the GBU, Sidewinder, or 20mm gunpod.
If added under Japan’s tech tree with Thailand’s subtree, it can serve as a good sidegrade to the Dornier Alpha Jet that is with the RTAF (The Alpha Jet was actually offered to the PH as well but PAF went for the cheaper AS.211). The true contention for this proposal will lie whether or not it can equip the Sidewinder missiles because afaik, I cannot find any documentation supporting it but the pictures can be reasonably inferred, and I dont think it is that hard to integrate the Sidewinders in a jet like this - especially one that have cannibalized F-5 parts.
If by CMs you mean Cruise Missiles, Im not too sure. In the base S.211 there wasnt even any provisions for guided bombs and some sources say that the AS.211’s guided bomb capability is through a buddy lasing system which would require a designator on the ground to lase the target so yeah, I dont think the AS.211 can carry any Cruise Missiles - or at least the PAF isnt that interested in fitting their AS.211s with Cruise Missiles and no one has attempted to.
