The company is aiming to meet launch requirements for both the Chinese national satellite internet project and also the CNSA solicitation for resupply of the Tiangong space station.

In April 2020, the company raised US$14 million in order to complete development of its 30 tf (66,000 lbf) liquid rocket engine Tianhuo-3, which had begun igniter hot fire tests in 2019.

Tianlong-1 is a kerosene-liquid oxygen (kerolox) fueled vehicle using the Tianhuo-3 engine, with a payload capacity to low Earth orbit exceeding 3 tonnes (6,600 lb).

[7] The maiden flight of Tianlong-2 took place on 2 April 2023, successfully carrying the Jinta cubesat from Hunan Hangsheng Satellite Technology to a Sun-synchronous orbit.

This mission represented the first successful launch of a Chinese privately funded, liquid-fueled, kerolox rocket with Space Pioneer becoming the first startup company to reach orbit on its maiden attempt.
