see how stupid soyuz launch pad is in vostochny now>? billions blown for nothing.... instead angara and sunkar launch pads should have been built.you cant built launch pad for angara + sunkar all in 1. sunkar is 4 times larger.
sunkar should be built in 4 years max , and launch pad too. they have zenit plans,engines, manufacture big tanks , everything... 7 years and with more delays it will probably be 10 years= massive coruption and siphoning of scarse resourses.
also look how they improved sunkar and rectify flaws from zenit , increase in fuel (and weight) of 9% but payload increase in 25%.
You are too harsh on Soyuz. There will always be medium payloads (eg 8T to LEO) for which Angara-1.2/Soyuz 2-1V is inadequate and A-3 is overkill, so Soyuz will keep its current niche. The manufacturing infrastructure exists and is wholly paid for, and a vast experience base exists for building and operating these vehicles and their pads. It's better to leverage that legacy and introduce incremental evolutionary improvements than to simply throw it all away (*). Modern Soyuz 2b is a totally different beast to the original Soyuz 11A511 launcher.
(*) BTW that's what the US does, mainly because their aerospace industry is all private and competitors wish to advance their own products over those of their competitors, and couldn't care less about retaining national capabiities which they themselves don't own).
Likewise, Vostochny is not a waste of billions, as much of the cost is for the common infrastruture that will be used by future non-Soyuz vehicles. Facilities like vehicle & payload testing and integration areas, fuel storage and handling systems, communications and radar facilities, accomodation blocks and administration buildings, roads and airport etc etc. The cost of the Soyuz pad is only a small component of the 1st stage of the Cosmodrome, and despite the blabberings of Atlanticist fuckwitz like A.Zak, a Soyuz pad was a necessary first step. Angara wasn't ready when Vostochny was conceived, and there was zero chance that either Proton or Zenit facilities would be replicated, let alone near-obselete boosters such as Kosmos or Tsyklon. Now the Cosmodrome is built, has an active launcher available, and can now be expanded and its tempo of operations increased as reliance on Baikonour is wound down.
Massive corruption? Oh, don't start with that BS... Only a fool actually believes that any signficant sum has been diverted by corrupt practises, and what funds are stolen are due ENTIRELY to criminal behaviour by the privately owned sub-contractors that Spetstroi must use on a project of this scale. The Russian gov seems to have been rather ruthless in punishing transgressors (ie thieves), so that is a good sign. Putins team has made huge strides in tackling corruption, but our 5th-column media pressitutes refuse to admit this in order to protect the "Russia is corrupt" narrative. There are still problems (as the recent arrest of the 2nd in charge of the governments anti-corruption watchdog attests to) but progress is being made, and corrupt gov officials will increasingly become an endangered species.
Agreed that Sunkar (or whatever it gets called) needs to be a substantial improvement on Cold-War era Zenit. So far, the publically-available specs look promising!
