Its maiden launch was conducted from a sea launch platform on January 11, 2024, breaking records as both the world's largest solid-fuel carrier rocket and China's most powerful commercial launch vehicle to date.

Gravity-1 consists of seven solid rocket motors (SRB) in total. The first four side-mounted SRBs are ignited on the ground, while three core boosters are air-lit in sequence. The launch cost for Gravity-1 is no higher than US$39 million. Gravity-1 offers a quick-response-time of only five hours between manufacturing completion and launch.Orienspace has signed contracts for the launch of more than one hundred satellites.
