China Tests Non-Nuclear Hydrogen Bomb in Breakthrough Weapons Trial

AsianFin -- Chinese scientists have successfully tested a hydrogen-based explosive device that unleashed intense, prolonged heat without using any nuclear materials, South China Morning Post reported, citing a study published last month.

The 2-kilogram (4.4-pound) device produced a fireball exceeding 1,000 degrees Celsius (1,832 degrees Fahrenheit) that lasted over two seconds—15 times longer than a comparable TNT explosion.

Developed by the 705 Research Institute under China State Shipbuilding Corporation (CSSC), a major force in underwater weapons development, the bomb utilizes a magnesium-based solid-state hydrogen storage material to trigger powerful chemical chain reactions.
