History
In October 2022, the construction of a fresh batch of ZQ-2 rockets was announced by LandSpace. A new variant of the TQ family of engines, designated as TQ-15A, was used in the second stage. The weight of the engine was reduced by 400 kg as a result of the elimination of the TQ-11 vernier thrusters, and vectoring is now done with a thrust vector control system that can angle up to four degrees. Additionally, the thrust will be enhanced and equipped with restart capabilities for greater mission profile flexibility.[2]
In March 2024, the first flight-ready TQ-15A was delivered for the assembly of Zhuque-2 Block 2.[3]
On November 27, 2024, an upgraded Zhuque-2E with a TQ-15A engine powering the second stage successfully placed 2 satellites into orbit.[4]
