设计特点
 
The DF-1 was a single-stage rocket powered by a 5D62 liquid rocket engine burning alcohol as fuel and liquid oxygen (LOX) as oxidiser. The engine had a sea-level thrust of 38 t, an Isp of 214s, with a burn time of 90s. The engine was developed by the Institute of Liquid Rocket Engine of the Fifth Academy, the Missile Assembly Plant (Factory 211), and the Fifth Sub-Factory of the Shenyang Liming Aero-Engine Plant. The development of the engine was completed in September 1960.
DF-1是由5D62液体火箭发动机提供动力的单级火箭，酒精为燃料，液氧（LOX）为氧化剂。发动机的海平面推力为38吨，Isp为214秒，燃烧时间为90秒。该发动机由第五研究院液体火箭发动机研究所，导弹总装厂（211工厂）和沈阳黎明航空发动机厂第五分厂开发。发动机的开发于1960年9月完成。
 
The DF-1 was a copy of the R-2 rocket, which itself was derived from the German V-2 but with doubled range. The missile was 17.7 m in length and 1.65 m in diameter, with four trapezoidal-shape stabilising fins attached to the bottom. The missile had a launch weight of 20.5 t, and a take-off thrust of 37 t. The maximum flight range was 590 km. The missile was transported on a truck-towed trailer, which also served as the launcher platform.
DF-1是R-2火箭的仿制型，它本身是从德国V-2衍生而来，但射程增加了一倍。导弹的长度为17.7米，直径为1.65米，底部装有四个梯形稳定鳍。该导弹的发射重量为20.5吨，起飞推力为37吨。最大飞行距离为590公里。 导弹是用卡车拖曳的拖车运输的，拖车也用作发射平台。
 
The missile was designed to carry a single high-explosive (HE) warhead, though no combat warhead had ever been developed. The DF-1 used an inertial guidance coupled with remote radio mid-course lateral correction. The later required a large antenna array to be deployed on either side of the launcher, making the launch unit easily detectable in the battlefield.
该导弹的设计目的是携带一颗高爆弹头，尽管从未研制出作战弹头。 DF-1使用了惯性制导，加上远程无线电中段横向校正。后者需要在发射架的两侧部署大型天线阵列，从而使发射装置在战场上易于探测到。
