The passing of Su Zhezi in Beijing marks the end of an era for China’s military-industrial complex. As a central figure in the Chinese Academy of Engineering, Su was instrumental in transitioning the People’s Liberation Army (PLA) from a force reliant on legacy Soviet designs to one equipped with world-class, indigenous precision strike capabilities. His vision for integrated firepower redefined how Beijing views the role of artillery on the modern, information-centric battlefield.
Su’s most enduring contribution was the Five-in-One design philosophy, which prioritized the fusion of digitalization, automation, and mechanization. By domesticating these complex systems, he enabled the PLA to deploy long-range, mobile artillery capable of day-and-night operations with high degrees of autonomy. This shift was not merely a technological upgrade but a strategic realignment that allowed Chinese ground forces to project power with greater precision and survivability.
Beyond domestic borders, Su’s leadership in the development of the 155mm export-grade artillery system turned China into a formidable player in the global arms market. These systems, known for their competitive range and sophisticated electronics, have become a centerpiece of China’s defense diplomacy in the Middle East and Africa. His work ensured that Chinese defense contractors could offer alternatives to Western and Russian hardware that were both technologically advanced and operationally robust.
Throughout his long career, which began in the late 1950s, Su remained at the forefront of China's quest for technological self-reliance. From his early days at state-run factories to his tenure as a chief designer at the China Academy of Ordnance Science, his trajectory mirrored the broader rise of China’s national strength. His death at 90 concludes a life dedicated to the quiet but profound transformation of the nation's military backbone.
