General Characteristics and Upgrade
The TA-4SU Super Skyhawk is the two-seat trainer variant of the A-4SU Super Skyhawk, which was a major modernization of the Douglas A-4S/A-4S-1 Skyhawk attack aircraft carried out by Singapore Technologies Aerospace (ST Aerospace) for the Republic of Singapore Air Force (RSAF) in the late 1980s. The upgrade transformed the aircraft by replacing its original underpowered engine with a modern turbofan and installing advanced avionics. The TA-4SU is unique among Skyhawk trainers, featuring a 710 mm (28 inch) fuselage plug and two completely separate cockpits, each with its own canopy, giving the rear-seat instructor excellent forward visibility. It was used for operational conversion and advanced jet training.
