South Korean KA-1 light attack aircraft, based on the KT-1 trainer.
ROK Air Force: "We need a low cost, light, ground attack and forward observer aircraft."
Ordinance Dept. "Bolt some hard points to your trainer and call it done."
A bit more than that. Full glass cockpit conversion with HUD for the weapons systems. 5 hard points total, capable of mounting hellfire missiles, rocket pods, dakka-dakka pods. Nimble little bugger with a punch, apparently well received by the pilots. KAI, the manufacturer, has had some success at gaining foreign sales.
What's old, is new again.
