Abstract
Abstract 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.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
111 words
An ocean launching apparatus for space rockets comprising: (a) a launch pad platform having a floating-island structure for launching at least one rocket; (b) a vehicle assembly building platform having a floating-island structure for servicing the rocket before launching; (c) a carriage for carrying said rocket serviced in the vehicle assembly building platform to the launch pad platform; (d) a hull having a semi-submersible structure adapted for ocean transportation of the launch pad platform and the vehicle assembly building platform, for loading and unloading of said platforms by a float-on/float-off method, and to serve as a floating foundation to keep said platforms in a line for combination work on the ocean.
