Experts in the course of the research have concluded that if Russia decides to abandon the deliveries of RD-180, which are used for American heavy carriers, this will lead to a revision of the entire segment of the American space program. In the US, more than 30 launches of carriers with Russian RD-180 are planned, and if these launches are canceled or even postponed, then the losses, according to the most modest estimates, will be 5 billions of dollars. If the United States decides to switch to developing its own engines of a similar type capable of replacing Russian ones, the first result will appear no earlier than 2020 of the year, which is unacceptable for NASA.
At the same time, American experts are confident that the United States itself must phase out Russian rocket engines for several reasons. One of them is this: the program to launch military satellites is tied to the use of the RD-180 in the USA. After Washington’s expanding sanctions package against Russia, Moscow said it was ready to supply rocket engines to the United States only for civilian projects. Launch programs in the interests of the military can be seriously affected.
