As before, Zenit launch vehicles will be used to put payloads into orbit. In fact, the rocket is considered Ukrainian, since it is assembled by Yuzhmash, but more than 80% of its components, including engines, are produced by Russia. Given the difficult relationship between the two countries, it was decided to carry out the final assembly of "Zenith" in the United States. Interesting fact: the Sea Launch platform is just 14 kilometers from the US coast and from the main office of SpaceX.
By the way, the Russian company S7 has become the first private domestic aerospace corporation, which should make a serious competition to the Americans.
