Kovalchuk noted that the Americans have been buying these rocket engines for many years:They disassemble, attach, disassemble, attach, but they cannot make metal”.
Kovalchuk explained that the difficulties in creating alloys for the manufacture of engines are typical not only for the aerospace industry, but also for the aircraft industry. Thus, it also limits the number of countries capable of producing engines for warplanes.
RD-180 engines are still used to power the Atlas V rocket, which is the main launch vehicle for launching US military satellites. For example, the last launch took place last October.
