The J-600T design is based on the B-611 SRBM developed by CASIC (China Aerospace Science and Industry Corporation) as a low cost tactical missile system, with a range of up to 250 km in improved versions such as the B-611M, and as a replacement for the M-11 (CSS-7 and DF-11) missiles in Chinese inventory. CPMIEC officials have confirmed at the IDEF 2007 military fair in Ankara that B-611M, the improved version of B-611, was not a part of the Sino-Turkish cooperation program.
