Wait, is there a new 637 Brigade? I can't find any info on them.
From what I heard, there were 5 rounds of DF-5 expansion and DF-5C won't be ready any time soon as the engine is still being tested and no maiden flight confirmed yet.
Btw are u sure that the new built silo is operational rn? And I am quite sure some silos construction come under radar because I heard from sources that some new DF-5 silos were built near Yueyang but I can't find them.
The 662 is an ex DF-4 BGD which had four ROTLs and one (DF-4) "silo" (elevated launch concept).
Now this unit will/has become a DF-5 unit. Definitely 12 silos (puls one trg) are under construction.
The four ex ROTL sites are looking finished and might be operational already.
Moreover there are definitely TWO new BGD (634 & 637). One of them (I think designation is 634) is similiar to the 662 and has 12 (plus one trg) silo construction of the type the 662 is getting.
But there is another BGD (I think designation is now 637) which has four new silo constructions of the type the 662 is getting.
They are at the former ROTL sites of the Tongdao (ex DF-4) unit. I've looked around this area but wasn't able to find (eight plus one) more silos to bring this field to a similiar configuration as with the 662 / 634.
So the purpose of these 4 new silo configuration is somewhat questionable for me. Maybe a further Training field / BGD?
I don't want to go into details for the 634 because I promised to wait until Decker Eveleth will come out with his new report and an updated map.
But the bottom line is that we have 30 [2x(12+1) + 4) new build DF-5 silos of which 4 are already without construction tents.
Together with the 3x6 old DF-5 silos we have 48!
Regarding the impressive ICBM figures of the 2022 Pentagon Report I have my doubts.
Their overall ICBM figure greatly depends on the guess of how many of the "sandy" silos (already without construction tents) of the Hami, Yumen and Ordos fields can be considered really OPERATIONELL!
Most of the silos are hardly recognizable and are covered with a kind of layer of sand. Most of the support facilities are also not yet completed. There are hardly any telltale activities at the silos. So I'm not sure if you can really classify every silo that doesn't have a construction tent as operational. I think that's just anticipated at the moment. In my opinion it will take another year or two before these sites are really operational.
In the days of the "Soviet Military Power" Publications, I attributed great precision to Pentagon publications.
But these days I'm not so sure if the information given in these yearly releases is really accurate.
I think there is also a certain proportion of "educated guesses" in there.
And for me it seems that only after Decker Eveleth and Hans Kristensen have found and unveiled these fields they finally included this information in the 2022 Pentagon Report.
The reported number (6) for the Type 093 submarines also seems a bit too small to me.
Elsewhere in the report they mention 9 SSN. However, the last three type 091 are not all available (if at all).
It's also a pity that they give so few details about the DF-17 (at least two BGDs and probably corresponding reduction of DF-11) and DF-100 BGD (in exchange for DF-10?).
Of course they know to do better, but it seems to me that they simply do not want to disclose this in the report itself.
In so far the figures of the Report must be viewed with caution.
Cheers
