first-stage engine assembly for LandSpace's Zhuque-2 rocket was completed in February 2021. It consists of four TQ-12 engines providing a takeoff thrust of 268 tons. 37 TQ-12 family engines have been built by LandSpace as of July 31, 2022, with a hot fire test duration of more than 20,000 seconds. A record-breaking 3357 seconds of hot firing time were accumulated by one engine after it was started 11 times.
