Hainan Commercial Spaceport Phase II Completes Main Works, Begins Integrated Testing

The Hainan build-out matters less as a single launch site than as capacity: two general-purpose medium liquid-fuel pads, sized for 5-meter-class two-stage vehicles, point to a launch cadence problem being addressed at the infrastructure layer rather than the rocket layer. The explicit Long March 12B tie-in signals that this capacity is spoken for by state-backed medium-lift programs, which shapes how much commercial access remains. The open question is whether integrated testing converts to declared launch capability within the stated year, since pad timelines have historically slipped.
