Together with a 48-ton oxidizer container, the rocket is estimated to weigh 91 tons, the report noted. The rocket itself was made of a mixture of aluminum and magnesium, AIMg6, and used kerosene, a combustible hydrocarbon liquid, as fuel, according to the report. The oxidizer container was made of several patch panels, which showed poor welding and uneven surfaces, an indication that North Korea seems to have no advanced technology in that area, the report said.
