The IAS Aquila is a single-seat, twin-engine swing-role attack and interception aircraft.

It's relatively cost effective design made it popular with the cash-strapped RSAF, ordering several hundred. The re-engined, re-winged M-2C variant operates, despite dated avionics and systems, to this day.

It features an internal gun, a gunpod on hardpoint 4, SAR-4A early infrared guided missiles and SAR-5A early radar guided missiles, of which the latter cannot be fired below 20 degrees downward pitch angle due to ground clutter, on hardpoints 1 and 7, two 400-gallon external fuel tanks on hardpoints 2 and 6, and finally two bomb racks of 500lbs bombs on hardpoints 3 and 5.
To use the weapons basically turn on all the switches on the armament panel.
