“They cannot launch Gonets-M [satellites] since 2017 due to a lack of components from Ukraine, needed to control systems of the upper stage Briz-KM. System hardware equipment is produced at the Kharkiv company Khartron. After 2014, Ukraine stopped the delivery of this equipment to Russia,” said the source of RIA Novosti.
According to him, the control system was supposed to be taken from the Russian Ministry of Defense which had the reserve equipment remained after the launch of Rokot [space launch vehicle] with military satellites, however, its transfer was delayed.
“Therefore, the possibility of further delays of Gonets-M launch is possible,” stated the source.
