What is CL-20?

June 5, 2023

A team of researchers from China has claimed a substantial enhancement in the safety of CL-20, one of the most potent explosive known worldwide. By implementing engineering advancements, they have managed to increase its shock resistance capacity by a factor of five.

CL-20: A Powerful Explosive

CL-20 is hailed as one of the most explosive non-nuclear substances on Earth. Its full name, Hexanitrohexaazaisowurtzitane, reflects its chemical composition. What sets CL-20 apart from other military explosives is its exceptional energy output. In comparison to commonly used explosives like RDX and HMX, CL-20 boasts a higher energy output, making it an intriguing prospect for military applications.

Enhanced Shock Resistance

China’s groundbreaking achievement lies in the development of a new method that enhances the shock resistance of CL-20. This innovative technique makes CL-20 five times more resistant to shock, setting the stage for potential large-scale mass production. This breakthrough holds immense significance, as it opens up possibilities for incorporating CL-20 into various Chinese projectiles and missiles.

Origin and Challenges

CL-20 was initially synthesized at the China Lake facility of the Naval Air Weapons Station in California, USA. Despite its remarkable properties, the widespread adoption of CL-20 has been limited due to high production costs. However, with the recent advancement in production methods, the potential barriers to its adoption may be mitigated.

Military Applications

The significance of CL-20 for military applications cannot be understated. Its higher energy output and lower sensitivity to shock and friction make it an appealing choice for developing more powerful and effective weapons. The improved shock resistance achieved through China’s new method opens doors for increased safety and reliability in the utilization of CL-20 in military operations.

Implications of Large-Scale Production

China’s successful large-scale mass production of CL-20 could bring about transformative changes in the realm of military technology. Incorporating CL-20 into Chinese projectiles and missiles has the potential to enhance their destructive power and precision. This advancement could strengthen China’s defense capabilities and have significant implications for future warfare strategies.
