If you read the article I posted the link to, Platform-O was "approved", but then basically not used for anything important.
Because they assigned the task of designing this to a company without experience in making heavy vehicles of that size, the company decided to use electric drive in order to not design complex heavy duty hydropneumatic systems they had no experience in designing. But the drive train turned out way heavier than expected and the electric drive has loads of issues with crossing water. So, this does not have anywhere near the hauling performance it was supposed to have. Probably also really expensive since it seems to have used one electric engine per wheel. Supposedly it is now being redesigned to use one electric engine per axle.
Anyway, just like I said, the Russian government can fix this problem for Tornado-S by designing a new vehicle using the BAZ-6909 tractor. But for the larger theater systems like Iskander or Bal, or strategic systems like Yars, still need to find a replacement to Platform-O. It remains to be seen what the Russian government will do on this matter.
Why were they OK with iskander and S-400 trucks being BAZ but not with the tornado S? Why didnt they just mass produce tornado S on kamaz chassis with reloadable palette module? There is no possible way this wouldve been troublesome to the russians. Is the BAZ autism also the reason the uragan 1M was canned?

Russians basically had a six shot himars with fully domestic components since 2009, yet 0 were produced.
