History

edit

Space Pioneer proposed the TH-11 engine for its Tianlong-2 launch vehicle. Full-system hot-fire tests were completed in June 2021.[2] The Tianlong-2 rocket successfully completed its maiden flight on April 2, 2023, achieving the targeted orbit. Powered by a single Tianhuo-11 engine in its second stage, this launch marked the engine's operational debut.[3]
