A Russian website published the classified information about satellites, the very existence of which was kept in secret. Meduza news agency reported that with the reference to RIA Novosti.

A presentation was made public; it included the list of satellites' names, launch times and the number of devices launched, as well as the data on research and construction works and enterprises involved in the development.

According to Sergei Likhonosov, Saturn company's Chief Constructor of Li-ion batteries, the man who designed certain parts of the satellites, the information was disclosed for a narrow circle of experts at a conference in Krasnodar, Russia in February 2019. 'This should not have become a matter of public knowledge', he said.

Saturn claimed they would prosecute those involved in the release of the presentation.

In February, Russia launched EgyptSat-A satellite, experiencing some trouble during the launch.

In early 2019, Russia lost the satellite for early warning of the missile attack; the device named Kosmos-2430 was launched in 2007.
