The rocket was powered by LandSpace's methane engines — the first stage had nine TQ-12A engines, creating the major lift for the rocket, while the second stage had a TQ-15A engine. Compared to traditional rocket engines that can function only once, a methane engine is reusable and more environmentally friendly.
The rocket's propellant tanks are constructed of stainless steel, which features good strength, resistance to high temperatures and corrosion, and are cost-effective. There were four grid fins and four landing legs on the space vessel that would have been used to enable the first-stage booster to make a soft landing.
