K1

The K1, sometimes referred to as the 88 Tank (88 전차), is a South Korean main battle tank designed by Chrysler Defense (later General Dynamics Land Systems) and Hyundai Precision Industry (later Hyundai Rotem) for the Republic of Korea Armed Forces. It is a derivative of Chrysler's M1 Abrams, tailored to meet unique ROK requirements. The K1A1 is an upgraded variant based on the GDLS technical data package with a 120 mm 44 caliber smoothbore gun, and is outfitted with more modern electronics, ballistic computers, fire control systems, and armor. Hyundai Rotem produced 1,511 K1 and K1A1 tanks between 1986 and 2011.
