The Chinese military has released footage showing the successful testing of the country’s version to the U.S. GBU-43/B Massive Ordinance Air Blast (MOAB).

According to the state-owned news agency Global Times, earlier this week, the People’s Liberation Army Air Force and the Chinese defense giant North Industries Group Corporation Limited (NORINCO) successfully tested a powerful bomb. Chinese officials claim that its destructive capabilities are second only to a nuclear munition.

The footage, which was recorded sometime in late December, shows an H-6K bomber releasing a huge bomb that is about five to six meters long. The promotional video was released by NORINCO. A company spokesperson stated it is not a thermobaric weapon, meaning, it doesn’t use oxygen from the surrounding air to produce a high-temperature blast. Conventional bombs use a mixture of gunpowder and fuel to explode, but thermobaric munitions use only fuel.
