Mike, the submunitions I listed were just for the 300mm rocket that has a range greater than 90Km. So there could be a lot more info on the site that Jeff mentioned. One thing about that site, 90% of the info seems to be coming from one guy.
No, that site is`nt very good. And your translation with google-translate is`t good, because it`s google

And US-Subs told right thinghts about translation.
On russian language you could fined and better site (with cutway and schemes)
