China's Rocket Factory Finds a Second Gear

China's Rocket Factory Finds a Second Gear

In 2024, China launched 68 orbital missions. In 2025, the number jumped to 97. In 2026, state media and Western analysts agree the target is 140 or more. Most of that growth is being driven by two state-backed mega-constellations, a half-dozen private launch companies hitting stride, and a deliberate national pivot toward commercial space. Beijing is no longer trying to catch SpaceX. It is trying to build an industrial base that outlasts one.
