Simply be cause "order for the older S-300V" will be made in making UPGRADES of existing

S-300V into S-300V4 standard (and even newer than that upgrades later on). All this comes for  2 reasons.

 

Main reason is delay of production year for  S-500 from 2015 to 2017. So the number of S-500 planned to be commisioned till 2020 will be lower.

That number (in S-500 missiles) will be compensated with (not removing but) upgrading of older S-300PMU2 and S300V missiles.

And S-400 will be produced in the planned numbers but not more than that,  short of capacity to compansate missing numbers of S-500

So only logical option, only solution left was upgrade of older S-300.

Again no problems with S-400.

S-300PMU2  systems will be upgraded and  S-400 missiles will be fitted into upgraded S-300PMU2 systems 

Also S300V will have upgrade into S-300V4  and newer upgrades later on till 2020.

 

 

Who the hell wrote this "analysis"?

  Just what S-300V series have to do with S-300P(PT, PMU, S-400) series? These are different systems, made by different R&D bureaus, serving a different purpose.

May 1, 2012: Despite having bought and put into service five S-400 (SA-21) anti-aircraft battalions during the last few years, the Russian Defense Ministry has placed a large (quantity unspecified) order for the older S-300V (SA-12) system. This seems to indicate that the S-400 is having problems (it has certainly encountered many delays).
