"China's Development of Hypersonic Railgun for Space Launches"

China is developing a giant railgun to launch its Tengyun spaceplane, while the US is focusing on hypersonic technology for satellite launches. The Tengyun spaceplane aims to carry crew, cargo, and release satellites into space, potentially conducting other missions such as satellite capture or surveillance. Both countries are racing to develop cost-effective methods for deploying multiple satellites quickly, with China potentially exceeding the US in tactically responsive space launch capabilities. While China's railgun-launched Tengyun may strengthen its capabilities, the US is focusing on reusable rockets to reduce launch costs.
