Singapore Technologies Kinetics Limited (ST Kinetics) (Chinese: 新科动力), in Singapore, is a strategic business area of ST Engineering and handles land systems and specialty vehicles. In 2000, ST Engineering acquired the Chartered Industries of Singapore (CIS) through ST Automotive, a subsidiary of ST Engineering, and the new company was named ST Kinetics. Given the initial charter of CIS to support the local defence requirements, the main defence customer of ST Kinetics remains as the Singapore Armed Forces (SAF). Besides manufacturing small arms and munitions, some of ST Kinetics' key military products include the SAR-21 assault rifle, the Bionix AFV, the Bronco ATTC and the Terrex APC. These weapons and ammunition are often made to U.S. or NATO specifications for export. The company holds a number of subsidiaries overseas, mainly in the U.S., Canada, China and India. Recent acquisitions between 2004 and 2009 have seen new construction equipment, specialised bodies and trailers for urban services being brought into ST Kinetics' stable of products, which was previously dominated by military weapons and platforms. Together with the other ST Engineering companies, ST Kinetics is part of the Singapore Defence Ecosystem of users, developers and producers in support of the Third Generation SAF.
