B-611

The B-611 missile and its derivatives are a series of Chinese short-range ballistic weapons (SRBM) first developed in the late 1990s by the China Precision Machinery Import and Export Corporation (CPMIEC). Typical targets intended for the B-611 include supply lines, warehouses, missiles sites, battery units, command centers, airfields, transportation hubs, and area targets in urban surroundings.

The B-611 missile with the NATO reporting name CSS-X-11, is the follow-on to the earlier Dongfeng-11 (M-11, with the NATO reporting name 'CSS-7'). The missile weighs approximately two tons and is powered by a solid rocket motor. The inertial guidance system with a mechanical gyro, provides an accuracy of Circular error probable (CEP) of 150 meters or better; this can be upgraded with a laser gyro or a fiber-optical gyro based on the customer’s request, thanks to the modular design concept adopted. When combined with other guidance systems such as that controlled by satellite, accuracy is increased ten-fold. Thanks to the same modular design concept, a variety of warheads can be equipped, increasing the versatility of the missile. A typical B-611 battery would include three vehicles, the transporter / erector / launcher (TEL), housing the missile, the communication and command vehicle, and a support vehicle.
