History of Development
In the early 21st century, global military powers recognized the potential of hypersonic technology to revolutionize strategic weaponry. Hypersonic glide vehicles (HGVs) offered the promise of delivering payloads at unprecedented speeds with enhanced maneuverability, rendering traditional missile defense systems less effective. China, aiming to bolster its strategic deterrence and counterbalance advancements by other nations, initiated the development of its own HGV.
The project, led by the Guizhou Aviation Industry Corporation (AVIC), began in the early 2010s. The primary objective was to create a vehicle capable of traveling at speeds exceeding Mach 5, with the ability to perform evasive maneuvers during flight. This would enable the weapon to penetrate advanced missile defense systems and deliver both conventional and nuclear payloads with high precision.
The WU-14, as it was initially designated, underwent its first flight test on January 9, 2014. Launched from the Taiyuan Satellite Launch Center in Shanxi Province, the test aimed to evaluate the vehicle’s aerodynamic properties and guidance systems. Over the next two years, China conducted a series of tests, with reports indicating at least seven flights by 2016. These tests demonstrated the vehicle’s capability to achieve hypersonic speeds and perform complex maneuvers, validating the design and guiding further refinements.
In 2017, the WU-14 was officially designated as the DF-ZF. The “DF” prefix stands for “Dong Feng,” meaning “East Wind,” a nomenclature used for China’s ballistic missile series. The DF-ZF was primarily paired with the DF-17 medium-range ballistic missile, designed to carry the HGV to the edge of the atmosphere before its release. This combination allowed the DF-ZF to glide towards its target at hypersonic speeds, making it difficult to track and intercept.
The development of the DF-ZF was not without challenges. According to Ye Youda, a scientist involved in the project, progress was hindered by inadequate computing resources. The team lacked priority access to supercomputers, and the available systems were not optimized for the complex simulations required for hypersonic flight dynamics. Despite these obstacles, the program advanced, leveraging both theoretical research and empirical data from flight tests.
By October 1, 2019, the DF-ZF was believed to have reached operational status, coinciding with its first public appearance during China’s National Day military parade. This milestone marked China’s entry into the exclusive group of nations possessing operational hypersonic weapons, alongside Russia and the United States.
The development of the DF-ZF was driven by the strategic imperative to counter advancements in missile defense technologies by other nations. Hypersonic glide vehicles, with their high speeds and maneuverability, present a formidable challenge to existing defense systems, thereby enhancing China’s deterrence capabilities. The DF-ZF’s ability to deliver both conventional and nuclear payloads adds a versatile tool to China’s strategic arsenal.
