FJ ABM Fan Ji ( 反击 , meaning counter strike ) anti - ballistic missile ( FJ ABM ) was the missile used in the HQ - 81 ABM system ( ABMS ) , which was the land based component of 640 - 1 ABMS project , which in turn , was part of the Chinese 640 ABMS project in the 1960s . Although the project was cancelled in Mar 1980 ' s , the experience gained had helped China in later ABMS development . 640 . The origin of FJ ABM traces back to December 15 , 1963 , when Mao Zedong first initiated the idea , and on February 2 , 1964 , the formal requirement was issued . Also in 1964 , the 2nd Academy of the 7th Ministry of Machinery Industry ( currently the 2nd Academy of China Aerospace Science & Industry Corporation ( CASIC ) ) , also known as the Ministry of Aerospace Industry , begun to work on proposal and establish programs at the same time . A plan outlining the missile defence weapon development submitted by Chinese Commission for Science , Technology and Industry for National Defense ( COSTIND ) was approved in August 1965 , and subsequently , the project was formally named as Project 640 ( 640工程 ) , because the requirement was formally issued in 1964 . However Project 640 was gravely disrupted by political turmoil in China , namely , the Cultural Revolution that erupted in 1966 . Further complication arose due to the complexity of the project , so in August 1969 , the project was reorganized into several major portions , each with its own designing establishment . Project 640 was divided into space - borne systems , which included CK - 1 ( 长空一号 meaning Vast Sky # 1 , with CK = Chang Kong ) ELINT satellite and FW - 1 ( 反卫一号 , meaning anti - satellite # 1 with FW = Fai Wei ) anti - satellite , and land - based systems . The land base systems were further divided into 5 different portions , including Project 640 - 5 : study on the re - entry of warheads of ballistic missiles , Project 640 - 4 : the early warning radars , Type 640 - 3 : the laser gun research project , Project 640 - 2 , the ABM super gun designated as Vanguard ( Xianfeng 先锋 ) , and Project 640 - 1 , the ABM missile system along with other supporting infrastructure , the primary portion of Project 640 . On August 14 , 1969 , Zhou Enlai reassigned the 201st Institute of 7th Ministry of Machinery Industry became the primary contractor of Project 640 - 2 , assisted by the 1410th Institute of the Ministry of Electronic Industry , and the 2nd Academy of 7th Ministry of Machinery Industry as the primary contractor of Project 640 - 1 . 640 - 1 . Project 640 - 1 included the construction of hypersonic wind tunnel with half a meter diameter . Constructed in the 1960s , it is still in use today for later missile and satellite programs , such as JL - 1 and JL - 2 , long after the cancellation of Project 640 . The location of Project 640 - 1 was in Yunnan , where one of the huge radar was located , and COSTIND Base # 24 , where most research was done , was located in Kunming , the provincial capital . The base was kept secret for decades even long after the cancellation of Project 640 , and it was not until 2010 ' s was it finally declassified . HQ - 81 . HQ - 81 ( 红旗 HQ = Hong Qi , meaning Red Flag ) is the ABMS of Project 640 - 1 , consisting of Type 715 engagement radars , FJ series missiles and other fire control systems ( but not including the early warning radars ) . During deployment , HQ - 81 system would be operating with information received from satellite and radars . One of the achievement of HQ - 81 is the S - 7 vehicle - mounted field computer , which was used for many other Chinese missiles developed later , such as DF - 5 , after Project 640 was cancelled . The need of such large computer was due to the calculations needed for the FJ series missiles and its Type 715 fire control radar , as well as other info provided by sources such as Type 110 and Type 7010 radars , and CK - 1 ELINT satellite . CK - 1 ELINT satellite . CK - 1 ( Chang - Kong Yi - hao 长空一号 ) ELINT satellite provided early warning of all - out attack from former - USSR . The primary contractor was Shanghai Steam Turbine Factory , the predecessor of current ( 上海电气电站设备有限公司 ) which newly formed a 701st Department ( 七零一车间 ) on October 31 , 1969 , specially for Shanghai 4101 Project , the project of CK - 1 program . Huayi Electronics Factory ( 华一电器厂 ) , the predecessor of current Shanghai Huayi Electronics Factory Co . Ltd ( 上海华一电器厂有限公司 ) was tasked to design the computer on board CK - 1 . CK - 1 was designed to intercept former - Soviet radar and air defense network signals , and communication signals . The intelligence gathered would be down linked to Chinese military for analysis to detect any signs of a surprise attack , which fortunately , never occurred , but the intelligence gathered was nonetheless valuable , and experience gained was used on later Chinese spy satellites . As with other Chinese military programs , CK - 1 also suffered due to the Cultural Revolution . After first two launches both ended in failures respectively on September 18 , 1973 and July 12 , 1974 , the following three launches via Feng Bao 1 rockets respectively resulted in success on July 26 , 1975 , December 16 , 1975 and August 30 , 1976 . Type 7010 radar . In addition to receiving intelligence resulted from the CK - 1 ELINT satellite , the primary early warning of HQ - 18 ABMS was the massive Type 7010 passive phased array radar . The general designer of Type 7010 radar was Mr . Shen Zhongyi ( 申仲义 , Mar 1922 - Apr 14 , 1988 ) , who was also the general designer of another radar of HQ - 18 ABMS , Type 110 . Mr . Shen Zhongyi was the head and the general designer of the 14th Research Institute at Nanjing , and the deputy director of the 10th Academy of Ministry of National Defense of the People ' s Republic of China ( eventually promoted to the director ) , and under his leadership , all radars of HQ - 18 ABMS of Project 640 were developed at the 14th Institute . Type 7010 passive phased array radar program begun in May 1970 , and installation work on the mountain 1600 meters above sea level begun in 1972 , at the northern slope of Mongolian gazelle mountain in Zhuolu County . In 1974 , the radar was rushed into operation even before its completion , which did not occur until 1976 and received state certification in the following year . The radar antenna array has a width of 40 meter and a height of 20 meter , with a total of 8976 transceivers . The peak power is 10 GW , with an average power of 200 kW , and a range in excess of 3000 km . Type 110 radar . Another long - range tracking radar of HQ - 81 ABMS of Project 640 is the Type 110 monopulse radar for long range precision tracking . Work first begun in 1959 for Project 110 simulation experimental radar after order was given in 1958 , and from 1965 to 1970 , more research were conducted , including the incorporation of Cassegrain antenna . When Type 110 finally entered service in 1977 , the system weighs more than 400 tons , with antenna diameter in excess of 25 meters . The radome of Type 110 was made of fiberglass , and at the time of its completion , it was the largest structure of its kind in the world , with height over 36 . 5 meters and diameter over 44 meters at the base . The range of Type 110 radar is in excess of 2000 km and it is located in Yunnan . Type 110 radar remain in operation today as a primary tools for space exploration . FJ - 1 . FJ - 1 was the most important member of FJ series ABM , and the name FJ - 1 was often used to replace HQ - 81 . The missile was 14 meters long weigh around 10 tons , and is launched at 50 degree angle . Originally adopting two stage liquid rocket motors , it was later improved to have one solid rocket motor and one liquid motor , and it takes around 20 minutes for the missile to be loaded to the launcher from the transportation truck . In February 1966 , three rounds of scaled down version of FJ - 1 for trials were completed , and successfully tested on February 19 to February 30 , 1966 . As with all Chinese projects at the time , FJ - 1 was seriously delayed by political turmoil at the time , the Cultural Revolution in China : In April 1972 , production batch 01 consisted of two rounds FJ - 1 were finally completed , but on May 15 , 1972 during tests in Kunming , both rounds blew up in the sky , resulting in failure of the test . Although measures were taken , it was not until finally in August and September 1978 , when the next batch were successfully tested in trials where the warheads of both the ballistic missile and FJ - 1 were replaced by dummy warhead filled with instrumentation . Despite the successful trial , the political climate change in China spelled to doom of FJ - 1 , which was finally cancelled on March 9 , 1980 , marking the end of entire Project 640 . FJ - 2 . FJ - 2 , the second member of FJ series missiles used in HQ - 81 ABMS begun in 1970 , and from October 1971 to April 1974 , the scaled downed model test rounds ( at 1 : 5 ratio ) of FJ - 2 completed six tests , with five resulted in success , only one ended in failure . Although started after FJ - 1 , FJ - 2 actually progressed faster than the former . However , the some capability of FJ - 2 overlapped that of FJ - 1 , while the remaining overlapped that of HQ - 3 and HQ - 4 surface - to - air missile s , so decision was made to pull the plug on FJ - 2 to be more efficient by concentrating on FJ - 1 and HQ - 3 / 4 . As a result , FJ - 2 was cancelled in 1973 . FJ - 3 . FJ - 3 , the last member of FJ series missile used in HQ - 81 ABMS begun in May 1974 , and it was a three stage rocket motor powered ABM launched from silo , but it was cancelled in 1977 . However , subsystems of FJ - 3 developed was used on other Chinese missile programs , such as the S - 7 vehicle mounted computer , which was later used on DF - 5 ballistic missile and other Chinese missiles .
