海南商发二号发射工位首次验证“四缸”技术，为更大火箭发射铺路

The second launch pad at Hainan Commercial Space Launch Site successfully completed its first four-cylinder hydraulic erection-system test using an Interstellar Glory Hyperbola-3 pathfinder vehicle. The exercise validated loaded erection, rapid rollback and coordination between the rocket and ground support equipment. The test was intended to prepare the pad for larger and heavier launch vehicles.
