The Rich History of Mianyang Sanxian Hewu Yanzhi Jidi Jiuzhi
The Mianyang Sanxian Hewu Yanzhi Jidi Jiuzhi, also known as the Three-Line Nuclear Weapons Research Base, holds a significant place in China’s historical narrative, particularly in the context of its military and scientific advancements. Established in 1965 under the code name 902, the base was constructed in Zizhong County, Mianyang City, and became operational by 1974. This strategic facility marked a pivotal moment in China’s defense strategy during the Cold War era.
The development of the base was part of China’s “Third Line” construction initiative, which aimed to bolster the country’s defense capabilities by relocating critical military and industrial assets to more secure, inland locations. Over the span of more than two decades, the base played a crucial role in the miniaturization and practical application of nuclear weaponry. It was here that significant advancements were made in the development of nuclear warheads and their integration with ballistic missile technology, effectively creating a credible deterrence against potential threats.
Throughout its operational years, the site was instrumental in conducting numerous nuclear tests—totaling 45 experimental detonations, with 22 of those being directed from this base. The facility not only contributed to the weaponization of nuclear technology but also laid the groundwork for the next generation of China’s nuclear arsenal, including advancements in missile technology.
The historical importance of the Mianyang Sanxian Hewu Yanzhi Jidi Jiuzhi is underscored by the presence of several key figures in China’s scientific community who worked there. Notable scientists and military leaders, many of whom were awarded the “Two Bombs, One Satellite” merit medal, were integral to the facility’s mission. Their combined efforts helped establish China as a formidable nuclear power.
In 1992, the base was relocated to the Mianyang Science City, but the original site remains a vital historical landmark. Recognized as a National Key Cultural Relic Protection Unit in 2019, the site has since evolved into a patriotic education center and a venue for nuclear science education.
