Annotation: One of the courses in the evolution of space rocket complexes is the relocation of launch sites for space launchers to the World Ocean. Firstly, it provides the opportunity to render space services for countries that encounter complications in fi nding locations for spaceports on land. Secondly, it allows for a larger number of launch azimuths. Thirdly, it helps to increase the payload capabilities of space launchers lifting from launch sites closer to the equator. The article reviews the current global progress in utilizing ships as part of sea-based space launch sites. It notes that more and more countries are becoming interested in the development and construction of maritime space launch sites. As one of the leading enterprises in the rocket and space industry, Yuzhnoye State Design Offi ce also conducts relevant research and development, which has already yielded a conceptual design for such a launch site for the Cyclone-1K lightweight space launcher. A specifi cally equipped naval vessel was selected as the launch platform for this rocket. The article outlines initial data applied for the overall design of the launch facility and the launch platform in particular. The design process involved modern software for 3D modeling and fi nite element analysis. A conceptual view and the primary characteristics of the launch platform, obtained through the design, are presented. The platform’s primary systems are described. The specifi city of equipment arrangement to support launch vehicle preparation and ensure the liftoff , as well as the relation between such arrangement and the launch platform’s appearance and internal structure, are demonstrated. The results of this work will be valuable for the practical implementation of the sea-based space launch site project. A fl oating launch platform is the essential element of a sea-based space launch facility, as it accommodates everything necessary for launching space rockets from the sea surface. Thanks to the versatility of the fl oating launch platform, it is possible to outline its appearance and characteristics according to the strategy for the launch services market.

Key words: sea launch, sea-based space launch site, space launcher, fl oating launch platform
