China’s military space program has been shaped by decades of development and strategy, emerging from the geopolitical ambitions of the Chinese Communist Party (CCP) under Mao Zedong and expanding into one of the most sophisticated and comprehensive space architectures in the world today. From its origins in the Cold War to its current role as a global space power, China’s space program has always been inextricably linked to its military objectives, designed to secure its national defense, enhance its global influence, and challenge the dominance of other space-faring nations like the United States. Understanding the evolution of China’s military space program requires examining key historical projects such as Project 640 and Project 640-1, as well as the gradual rise of its satellite network, which has laid the foundation for China’s current military capabilities in space.
Historical Context: Project 640 and 640-1
China’s early efforts to develop a military space capability can be traced back to the 1960s, under the leadership of Mao Zedong. These early initiatives were part of a broader strategy aimed at modernizing China’s military, achieving self-sufficiency in defense technology, and countering the strategic advantages of global superpowers, particularly the United States and the Soviet Union. Central to this early development was Project 640, China’s first comprehensive effort to build a missile defense shield and explore anti-satellite (ASAT) capabilities.
Project 640: China’s Early Missile Defense and Anti-Satellite Initiatives
Project 640, initiated in the late 1960s, was China’s attempt to establish a domestic missile defense system. This project came in response to the growing threat posed by intercontinental ballistic missiles (ICBMs), which had become a critical component of the Cold War arms race. China, having observed the missile defense efforts of the United States and the Soviet Union, sought to develop its own capabilities to protect itself from potential missile strikes. Mao Zedong, seeing the importance of controlling strategic high ground, was determined to make China a space power.
Project 640 had several components, including radar development, missile interceptors, and tracking systems. One of the central aims of the project was to create a network of ground-based radars that could detect incoming missiles and provide real-time data to guide interceptor missiles to their targets. This radar network was seen as the first step in developing an integrated air and missile defense system. The development of early radar and tracking systems was a major technological challenge for China at the time. The country’s technological base was still relatively underdeveloped, and it lacked the expertise and industrial capacity to quickly produce the sophisticated equipment needed for missile defense. Nonetheless, China’s engineers made significant progress. By the early 1970s, Chinese scientists had developed a prototype radar system capable of detecting long-range missile launches. This system, though primitive by modern standards, laid the groundwork for future advancements in radar technology that would become crucial in China’s space and missile defense programs.
However, Project 640 faced significant challenges from the outset. It was plagued by technical difficulties, resource shortages, and the broader political and economic instability of the Cultural Revolution. Despite these setbacks, the project did achieve some limited successes. For example, by the mid-1970s, China had developed the Fanji-1 (FJ-1) missile interceptor, which was designed to intercept and destroy incoming ballistic missiles. Although the FJ-1 system never became fully operational, it represented an important step in China’s missile defense efforts.
In addition to missile defense, Project 640 also included plans to develop anti-satellite (ASAT) weapons. Mao’s regime recognized the importance of space as a strategic domain and sought to develop the capability to disable or destroy the satellites of potential adversaries. This was particularly important in the context of the Cold War, where space-based reconnaissance and communication satellites were playing an increasingly important role in military operations. Although China’s early ASAT efforts under Project 640 were rudimentary and largely experimental, they laid the conceptual foundation for more advanced ASAT systems that would be developed in later decades.

Project 640-1: China’s Early Anti-Satellite (ASAT) Weapons
An offshoot of Project 640, Project 640-1, was specifically dedicated to the development of anti-satellite (ASAT) weapons. This project reflected China’s recognition of the growing importance of space- based assets in military operations. By the late 1960s and early 1970s, both the United States and the Soviet Union were using satellites for a wide range of military purposes, including reconnaissance, communications, and navigation. China, realizing that these satellites represented critical vulnerabilities in its adversaries’ military systems, sought to develop the means to disrupt or destroy them.
Project 640-1 focused on the development of kinetic ASAT weapons-systems designed to physically destroy satellites by colliding with them or striking them with missiles (Co-orbital and Direct Ascent ASAT Weapon Systems). Early concepts for ASAT weapons included both ground-based and space- based systems. China’s engineers explored the possibility of using ballistic missiles to launch interceptor vehicles that could target satellites in low Earth orbit. These interceptor vehicles would be equipped with either explosive warheads (Direct Ascent) or simple kinetic impactors designed to destroy satellites by ramming into them at high speeds (Co-Orbital).
Like Project 640, Project 640-1 faced significant technical challenges. China’s early missile technology was relatively unsophisticated, and developing the precise guidance systems needed for ASAT operations proved difficult. Nonetheless, Chinese scientists and engineers persisted, and by the 1980s, they had developed more advanced missile and guidance technologies that would later be applied to ASAT weapons.
Although Project 640-1 did not immediately produce an operational ASAT system, it played an important role in shaping China’s approach to space warfare. The project laid the conceptual and technological groundwork for the development of more advanced ASAT capabilities in the following decades. In particular, it helped China develop a better understanding of the complexities of targeting and destroying satellites, as well as the potential benefits of doing so in a conflict. This knowledge would prove crucial as China continued to develop its space and missile capabilities in the 21st century.
Key Milestones in China’s Military Space Program
The early efforts of Project 640 and 640-1 set the stage for the development of China’s modern military space program. Over the following decades, China made significant progress in building a robust and sophisticated space infrastructure, which today plays a central role in its military strategy. Several key milestones mark the evolution of China’s military space capabilities, beginning with the launch of its first satellite and culminating in the development of advanced reconnaissance, navigation, and communication satellites that support the People’s Liberation Army (PLA).
• The Dong Fang Hong Series: China’s First Steps into Space
China’s entry into the space age began in 1970 with the launch of its first satellite, Dong Fang Hong 1. This satellite, whose name means “The East is Red,” was a major propaganda victory for the Chinese Communist Party, demonstrating China’s technological capabilities and marking its arrival as a space- faring nation. Although Dong Fang Hong 1 was primarily a scientific satellite with limited military applications, its launch was a crucial first step in the development of China’s space program.
Following the launch of Dong Fang Hong 1, China continued to develop its satellite capabilities, focusing initially on scientific and communication satellites. However, by the late 1980s and early 1990s, China began to develop satellites with clear military applications. One of the most significant developments during this period was the launch of the Fanhui Shi Weixing (FSW) series of satellites, which were China’s first recoverable reconnaissance satellites. These satellites were equipped with cameras that allowed them to capture high-resolution images of the Earth’s surface, providing valuable intelligence for the PLA.
The FSW satellites represented a major step forward in China’s military space capabilities. They allowed China to conduct its own satellite-based reconnaissance, reducing its reliance on foreign sources of intelligence and giving it the ability to monitor military activities in other countries. The success of the FSW program laid the groundwork for more advanced military reconnaissance satellites that would be developed in the 21st century.

• The Yaogan Series: Expanding China’s Military Satellite Network
The next major milestone in the evolution of China’s military space program was the development of the Yaogan series of satellites. First launched in 2006, the Yaogan satellites are a family of military reconnaissance satellites that provide the PLA with a wide range of intelligence capabilities. These satellites are equipped with a variety of sensors, including synthetic aperture radar (SAR), optical imaging systems, and signals intelligence (SIGINT) payloads. Together, these sensors allow the Yaogan satellites to conduct all-weather, day-and-night surveillance of military activities around the globe.
The Yaogan satellites are a key component of China’s efforts to build a modern, networked military. They provide the PLA with real-time intelligence on the movements and activities of potential adversaries, allowing Chinese commanders to make informed decisions about military operations. The Yaogan satellites also play a crucial role in supporting China’s missile forces, providing the data needed for accurate targeting of long-range ballistic and cruise missiles.
One of the most significant features of the Yaogan satellites is their use of SAR technology. SAR allows satellites to capture high-resolution images of the Earth’s surface regardless of weather conditions or lighting. This capability is particularly valuable for military reconnaissance, as it allows the PLA to monitor areas that might otherwise be obscured by clouds or darkness. SAR also enables the detection of objects that might be hidden from optical sensors, such as camouflaged vehicles or underground bunkers.
In addition to SAR, the Yaogan satellites are equipped with optical imaging systems that provide high-resolution images in the visible and infrared spectra. These images are used for a wide range of military applications, including mapping, targeting, and damage assessment. The SIGINT payloads on the Yaogan satellites allow them to intercept and analyze electronic signals, providing the PLA with valuable information about the communications and radar systems of potential adversaries.
The development of the Yaogan series marked a significant leap forward in China’s military space capabilities. It gave the PLA the ability to conduct global surveillance and reconnaissance on a scale that was previously the domain of the United States and Russia. The success of the Yaogan program has also spurred further investment in China’s military satellite capabilities, leading to the development of even more advanced reconnaissance satellites in the years since.
• The Beidou Navigation System: A Strategic Military Asset
Another key milestone in China’s military space program is the development of the Beidou Navigation Satellite System. Beidou, which began as a regional navigation system in the early 2000s, has since evolved into a global navigation system that rivals the U.S.-controlled Global Positioning System (GPS). Beidou provides the PLA with a secure and reliable means of navigation, positioning, and timing, all of which are critical for modern military operations.
Beidou’s development was driven in part by China’s desire to reduce its reliance on GPS, which is controlled by the U.S. government. During the 1990s and early 2000s, China realized that in the event of a conflict with the United States, its military forces could be denied access to GPS, leaving them vulnerable to disruption. To address this vulnerability, China began developing its own navigation system, which would allow it to operate independently of foreign systems.
The first phase of the Beidou system, known as Beidou-1, was completed in 2003 and provided regional coverage for China and its surrounding areas. However, this early version of Beidou had limited capabilities and was not sufficient for China’s global military ambitions. In response, China embarked on the development of Beidou-2, which provided expanded coverage across the Asia-Pacific region. By 2012, Beidou-2 had become fully operational, providing the PLA with a reliable means of navigation and timing throughout the region.
The most significant milestone in the development of Beidou came with the launch of Beidou-3, which expanded the system’s coverage to a global scale. Beidou-3, which was completed in 2020, consists of 35 satellites that provide global positioning, navigation, and timing services. This system allows the PLA to conduct military operations anywhere in the world without relying on GPS, giving China a significant strategic advantage.
Beidou’s military applications go beyond navigation and timing. The system also provides the PLA with secure communications and the ability to conduct precision strikes using satellite-guided munitions. Beidou is integrated into a wide range of Chinese weapons systems, including ballistic and cruise missiles, unmanned aerial vehicles (UAVs), and artillery. This integration allows the PLA to carry out highly accurate strikes against enemy forces, even in contested environments where GPS might be unavailable or unreliable.
• Advanced Satellite Networks and China’s Global Ambitions
In addition to the Yaogan and Beidou satellites, China has developed a range of other military satellite systems that support its global ambitions. These include communication satellites, missile early warning satellites, and electronic warfare satellites. Together, these systems form a comprehensive space architecture that allows the PLA to conduct a wide range of military operations, from reconnaissance and surveillance to command and control.
One of the most important developments in China’s military satellite program is the establishment of a network of communication satellites that provide the PLA with secure and reliable communications across the globe. These satellites allow Chinese commanders to maintain contact with their forces, even in remote or contested areas. They also provide the data links needed to support China’s growing fleet of unmanned systems, including UAVs and autonomous submarines.
China’s missile early warning satellites represent another significant milestone in its military space program. These satellites are designed to detect and track ballistic missile launches, providing the PLA with the early warning needed to defend against missile attacks. This capability is particularly important in the context of China’s nuclear deterrent, as it allows Chinese commanders to respond quickly to any potential nuclear threat.
Finally, China’s development of electronic warfare satellites reflects its growing emphasis on information warfare and the need to dominate the electromagnetic spectrum. These satellites are equipped with sensors and jammers that can disrupt enemy communications, radar, and navigation systems. In a conflict, these capabilities would allow the PLA to degrade the effectiveness of an adversary’s military operations, giving China a significant advantage on the battlefield.
Anti-Satellite (ASAT) Capabilities and Space Militarization
China’s development of Anti-Satellite (ASAT) capabilities represents a significant threat to global security and the strategic assets of the United States and its allies. The increasing militarization of space is no longer a distant possibility but a present and urgent challenge, with China actively working to enhance its ability to disable, disrupt, or destroy adversaries’ satellites. These ASAT capabilities are not simply isolated achievements but part of a larger strategy by China to assert dominance in space and challenge the military superiority of the United States.
The implications of China’s ASAT capabilities are profound. Satellites form the backbone of modern military operations, supporting everything from communications and navigation to intelligence gathering and missile guidance. The ability to attack these satellites gives China a significant strategic advantage in any future conflict, particularly against a technologically superior adversary like the United States. By developing both kinetic and non-kinetic ASAT technologies, China is building a comprehensive suite of weapons that could cripple the space-based assets upon which modern military forces depend on.
