The K1, also known as Type 88 by American engineers, 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. The vehicle's design was based on technology from Chrysler's M1 Abrams, tailored to meet the ROK's unique requirements. The K1A1 is an up-gunned variant with a 120 mm 44 caliber smoothbore gun, and 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.
