About the Angara rocket
Something about the Angara rocket is something that caused the Pindos to get nervous.
If it is explained entirely on the fingers, for non-specialists, the Angara is able to reach low orbit with an unmounted second stage, and with a certain amount of fuel in this second stage. And make several revolutions around the Earth before switching on the second stage engines - then change the orbit on this stage, or vice versa - slow down and dump your load into the atmosphere, or accelerate the load to the second space velocity without using the third stage (upper stage).
In general, this means that the Russians can now pull a significant load (satellites and "non-satellites") into orbits that were previously considered difficult to reach for launches located in Russia. Those orbits on which groups of satellites of the USA are grazed. Now among them may appear Russian "research vehicles."
In addition, such a strange rocket is generally difficult to track. It can change the orbit outside the zone of view of American locators,to throw off a small spacecraft unobtrusive to radar and once again change the orbit - and this is a real headache for the US tracking systems.
Under the control of the space forces of the Russian Federation will be the whole world. Yes, yes - the Ministry of Defense of the Russian Federation so directly stated.
