In 2017, S7 Space bought Sea Launch fromthe bankrupt Swiss company Sea Launch for $ 100 million. It was planned that until 2023 the company would launch Ukrainian launch vehicles Zenit from the Odyssey platform, and then transfer to the Russian Soyuz-5. The first launch was scheduled for 2019.
The reason for the transfer of the platform were difficulties with the agreement concluded between Russia and the United States. It deals with the launch of Zenit missiles, but their production ceased in 2014.
“Even if in the future it will be possible to sign a newan intergovernmental agreement, the Russian side will have to disclose to the American supervisory authorities the technical documentation on the new rocket in order to obtain a launch license, which Moscow will not accept. The only way out is to relocate the Sea Launch to Russian territory. ”
