Chinese Engineers Simulate Triple Nuclear Strike in Laboratory Experiment

Groundbreaking Simulation Conducted in Nanjing

Engineers from the People's Liberation Army (PLA) in China have reportedly carried out a pioneering laboratory experiment simulating the effects of a multi-point, high-yield nuclear explosion. The research, led by associate professor Xu Xiaohui from the Army Engineering University in Nanjing, focused on the impact of three nuclear warheads detonating in rapid succession at the same target deep underground. The findings were published on September 10 in the peer-reviewed journal Explosion and Shock Waves.

This marks the world's first laboratory system capable of such a simulation, addressing a critical challenge in modern warfare: the elimination of deeply buried and hardened underground targets that even powerful conventional weapons may fail to destroy.

Experimental Methodology and Results

The simulation employed advanced laboratory equipment, including vacuum chambers and a two-stage high-pressure gas gun. The process involved projectiles breaking glass pressure spheres, which generated a sudden release of energy equivalent to miniaturized nuclear explosions. Researchers were able to model and measure the impact of clustered detonations without conducting actual nuclear tests. The time interval between each simulated detonation was as short as 0.8 milliseconds.

The results indicated that the combined effect of these successive detonations was not merely additive but exponentially more powerful. The simulated craters were observed to be over twice as deep and wide compared to those recorded in older nuclear tests, such as the 1965 Palanquin experiment. Furthermore, surface-level destruction was found to be multiple times greater, raising significant concerns regarding the future landscape of nuclear warfare.

Strategic Implications and Broader Context

Historically, studies on nuclear earth-penetration effects have primarily concentrated on single-warhead detonations. However, with rapid advancements in modern defense engineering, new low-yield, precision-guided, earth-penetrating nuclear weapons, reportedly operational in US and Russian arsenals, are being designed with multiple independently targetable re-entry vehicles. This Chinese research represents a significant step towards understanding the destructive potential of such coordinated, multi-pronged attacks.

The experiment comes amidst reports of China's rapidly expanding nuclear arsenal. Estimates suggest that China's nuclear warhead count exceeded 600 by mid-2024 or early 2025, with projections indicating over 1,000 operational warheads by 2030. This ongoing modernization and expansion underscore a broader strategic shift in global nuclear capabilities.
