Zhuque-3 (ZQ-3) is a reusable orbital launch vehicle developed by Chinese private company LandSpace. The rocket is built using stainless steel and shares the same series of gas generator cycle methane/liquid oxygen powered rocket engines as in the currently active ZQ-2E rocket. The first stage uses 9 TQ-12 engines (initially the TQ-12A, then upgraded TQ-12B) while the second stage uses 1 TQ-15 engine (TQ-15A, then TQ-15B). On launch missions where the first stage is recovered, it will land on a down-range landing pad located in Minqin County, Gansu Province.
