An ocean launching apparatus of space rockets comprises a launch pad platform having a floating-island structure and a semi-submersible hull for loading and transporting the launch pad platform. When the apparatus reaches an intended ocean area, a rocket set on the launch pad platform is floated from the hull in a semi-submersing state on the ocean together with the launch pad platform and moved to a launching site. In this way, it is possible to provide an ideal launching site of space rockets, increase an economical efficiency of launching of space rockets, and guarantee the safety if an accident should occur.
