On June 18th, this year's 618 was not only an Internet shopping festival, but also a shopping festival for many private aerospace enterprises.
Because New Yuan Aeronautics opened up its entire engine series and recovery control systems for sale, the previously struggling private companies suddenly picked up steam.
There were 5-meter-class reusable rockets using single K380V engines, which covered a near-Earth orbit capacity range of 9 to 30 tons through a combination of CBC configuration and second stages.
There were also companies developing 7-meter-class heavy rockets using multiple K120 engines, and even some copying Musk's Starship or developing small spaceplanes.
Having engines indeed enabled them to do as they pleased, and other previously inconspicuous private aerospace companies emerged from isolation, starting to accelerate development through commercialization.
