China tests non-nuclear hydrogen bomb, science paper shows

Chinese researchers have successfully detonated a hydrogen-based explosive device in a controlled field test, triggering devastating chemical chain reactions without using any nuclear materials, according to a study published last month. The 2kg (4.4lbs) bomb generated a fireball exceeding 1,000 degrees Celsius (1,832 degrees Fahrenheit) for more than two seconds – 15 times longer than equivalent TNT blasts – without using any nuclear materials, it said. Developed by the China State Shipbuilding Corporation’s (CSSC) 705 Research Institute, a key player in underwater weapon systems, the device uses a magnesium-based solid-state hydrogen storage material.
