The Hyperbola-1 (aka Shuang Quxian-1, SQX-1) (Chinese: 双曲线一号) rocket is 20.8 m (68 ft) tall, 1.4 m (4 ft 7 in) in diameter and weighs 31 t (34 tons). It consists of four all solid fuel stages, guided by liquid fuel attitude control engines. It can launch 300 kg (660 lb) into low Earth orbit (LEO). The rocket might be based on Chinese military missiles (perhaps DF-11 or DF-15). The first stage of the rocket is equipped with four grid fins. The launch price is reported around US$5 million.
