The DF-3 is China’s first operational intermediate-range ballistic missile. The missile is a single-stage, liquid-propellant design carrying a single nuclear warhead.“东风”（DongFeng）-3是中国第一种中程弹道导弹（IRBM）。导弹是单级，液体推进设计能携带一枚单一的核弹头。
The DongFeng-3 (DF-3, NATO designation: CSS-2) is a single-warhead, single-stage, liquid-propellant, intermediate-range ballistic missile (IRBM). Developed in the 1960, it is China's first independently developed ballistic missile. The DF-3A is the improved variant with extended range developed in the early 1980s. A total of 150~200 DF-3/3A missiles are believed to have been deployed, with 30~40 remaining in service today.
Following the success in the DF-1 short-range and DF-2 medium-range surface-to-surface ballistic missile, China began to develop a brand new design with intermediate-range in the early 1960s. Unlike the DF-1 and DF-2, which were both developed from the Soviet R-2 ballistic missile, the new intermediate-range ballistic missile (IRBM) is a totally new design. Several design proposals were compared before the storable liquid fuel rocket with a cascade compensation inertial guidance design was finally chosen in early 1964. Three flying tests were carried out between December 1966 and May 1967, and the missile entered operational service in 1970 as DF-3.
The DF-3 was originally designed to cover the U.S. bases in the Far East, with about 150~200 missiles reported to have been deployed. A further 50~100 DF-3A missiles have been deployed since the late 1980s.中国DF-3导弹的设计去计划覆盖美国在东亚的基地，大约150~200枚导弹据报道已经部署，进一步50~100枚DF-3A导弹已经从1980年起部署。
In additional to nuclear warhead, the DF-3 can also be configured to carry conventional high-explosive warhead. The missile has a payload of 2,000kg.“东风”（DongFeng）-3携带一枚单一核弹头，也能携带一枚高爆战斗部。导弹负载2,000kg。
The 2,500km-range DF-3 was designed to over the U.S. bases in Eastern Asia. The missile has a payload of 2,000kg, which was expected to be the weight of the hydrogen bomb under development in China at that time. By the late 1970s, around 100~150 missiles are believed to have been deployed in PLA Second Artillery Corps bases in Jilin, Jiangxi, Yunnan and Qinghai. Depending on their deployment locations, these missiles can reach Japan, Philippine, South and Central Asia respectively.
In 1981 China began to develop the DF-3A with an extended range of 2,800km as well as improved accuracy. The flying tests took place successfully in December 1985 and January 1986. Unconfirmed reports suggest that China may have tried to develop a multiple re-entry vehicle (MRV) type for the DF-3 but this was unsuccessful. A conventional high-explosive warhead variant of the DF-3A was developed for an export order to Saudi Arabia in 1987. Since the late 1990s, the PLA began to gradually phase out the early variant DF-3 missiles and replace them with the more capable DF-21.
The DF-3 entered operational service in 1970, with about 150~200 missiles reported to have been deployed. A further 50~100 DF-3A missiles have been deployed since the late 1980s. China also exported 60~120 conventional warhead DF-3 missiles to Saudi Arabia, though no known test launch has been made in the country.
DF-3在1970年进入了操作服役，大概150~200枚导弹据传闻已经被部署。 进一步的50~100枚DF-3 A导弹已经从1980年后期以后被部署。中国对沙特阿拉伯输出了60~120枚传统弹头DF-3 导弹，虽然没有已知的试射在这个国家被安排。
The DF-3 is launched from fixed launch pad, and is road-mobile on a four-wheel carriage towed by 8X8 heavylift truck.DF-3从固定的发射台发射，而且在由8X8重型卡车牵引的四轮拖车架上公路机动。
The DF-3 is launched from fixed launch pad, and is road-mobile on a four-wheel carriage towed by 8X8 heavylift truck. Possible launch bases of the DF-3 include Dalong, Datong, Dengshahe, Dienwei, Fungrun, Jianshui, Kunming, Lianxiwang, Liujikou, Tonghua, Wuwei, Xian and Yidu. The DF-3 training facility is located in Wuwei, Gansu Province.
The DF-3 uses a single-stage liquid-fuel rocket motor, which requires a time-consuming complex fuelling process before the missile is ready for launch.采用液体燃料的DF-3导弹在发射前需要进行复杂的准备。
The DF-3 is a single-stage, single-warhead intermediate-range ballistic missile system. The maximum range is 2,500km (2,800km for DF-3A). It uses storable liquid propellants and a cluster of four engines. The pre-launch preparation time is reported to be between 2 and 3 hours. However, if the payload were reduced, then the DF-3A version would have the capability to achieve a range of about 4,000km.
DF-3是一种单级、单弹头中程弹道导弹系统。最大的射程2,500公里（2,800公里为DF-3 A）。它使用耐储存液体推进剂和四台集群发动机。预先发射准备时间据报告在2到3小时之间。然而，如果载荷被减少，那么DF-3 A型会有能力达到大概4,000公里的射程。
The DF-3 uses vanes in the efflux nozzles for control during the boost phase of flight. The motor consists of a cluster of four YF-2 engines which use storable liquids, Unsymmetrical Dimethyl Hydrazine (UDMH) fuel and AK-27 oxidiser (nitric acid with 27% nitrogen tetroxide), and provide a total thrust of 96 tonnes. The motors have a burn time of around 140 seconds. This gives the DF-3 missile a minimum range of 750km and a maximum range of 2,650km. At maximum range, the peak velocity of DF-3 will be 4.7km/s. DF-3 has a separating warhead assembly, weighing 2,150kg.
The missile uses an inertial guidance, with an estimated CEP of 1,000~4,000m. The missile carries a 2,000~3,000kT yield nuclear warhead, but can also configured to carry a conventional HE warhead. The improved DF-3A version has an accuracy improved to 1,000m CEP.
