On October 13, 2021, the Chinese private rocket company Beijing Deep Blue Aerospace Technology Co., Ltd. at the Tongchuan aerospace base conducted flight tests of a prototype of its partially reusable Nebula rocket (星云 一号) with a “雷霆 -5” rocket engine (LT-5) – “Thunder-5”, fueled by kerosene and liquid oxygen. Beijing Deep Blue Aerospace is developing two launch vehicles:
the light class, which will be able to lift 500 kg of cargo into a 500-kilometer sun-synchronous orbit and the middle class with a carrying capacity of 4.5 tons into low-earth orbit. Both launch vehicles will operate on kerosene / liquid oxygen fuel vapor. The first stage of the rockets will be reusable.
