J-201 missile, and its predecessor (265-I missile) and successor (J-202 missile) are members of a family of anti-tank guided missile (ATGM) developed by the People's Republic of China. This is the first family of ATGM in Chinese service, and also the first indigenously developed Chinese ATGM. 265-I Many missiles have been introduced to Chinese service from the USSR during the honeymoon between the two countries in the 1950s, but ATGMs were not among them, because it was not considered a top priority in comparison to other missiles. It was not until July, 1958, when China formally begun the development of its first ATGM by preparing the basic infrastructures needed. However, the relationship between China and the USSR had already begun to deteriorate, and Soviet advisors were soon withdrawn from China before it could obtain any information on ATGMs. However, the desperately needed technical info was filled by an unexpected source. China had backed leftist guerrillas during the independent movements in third world countries. In these armed struggles, captured samples of French-made Nord SS.10 were sent to China for study. Although none of the samples were complete (and all of them were too fragmented to be put back together to form a single completed unit), they were enough to provide a general knowledge for the Chinese to have a basic understanding of how ATGMs work, their design principles, and the basic elements for reverse engineering. Beijing Industrial Academy, the predecessor of Beijing Institute of Technology, was tasked as the contractor to develop an ATGM based on Nord SS.10, and the 724th Factory was tasked as the subcontractor for production. After two successful test flights, the missile was rushed into very limited service for evaluations, and it was designated as 265-I, named after the project number / code. However, the result was less than satisfactory from feedbacks, because like Nord SS.10 it is based on, 265-I ATGM is a vehicle mounted ATGM and could not carried by infantry. Chinese army was still mostly consisted foot soldiers because China could not field large numbers of vehicles like western countries at the time, and a man-portable ATGM was needed. As a result, 265-I ATGM never entered mass production like other Chinese missiles. According to Chinese, the importance of 265-I ATGM is that it paved the way for future Chinese ATGM development by laying the foundation for the future. From the experienced gained from the
