I was just wondering…could does anyone happen to know the lengths (and weights, too, if possible) of a couple of Soviet nuclear weapons? The RDS-6 (“Joe-4”) and RDS-4 (“Joe-2”), to be exact.
Side-view photos or diagrams would be great, too, but not completely necessary.
Can anyone help me out?
Here are some pictures, but I could not find any information on their lengths, sorry.
Yeah, that’s one of the few sites I managed to find on the subject. 
Thanks anyway, though!
I don’t know much about Russian nukes at all, but I’m ok with Google.
This site says the RDS-4 is 930kg… (they probably got it the same place these guys did.)
This site says it’s 1200kg though. (Perhaps a slight variant?)
Page 8 of this pdf says the RDS-6 was designed to be within 5 tons, but who knows what it actually was.
Hmm. I’d say you need to pay a visit to a library for this type of thing.
