      Interesting photo of early Chinese fission bomb. Looks like it used a type of in flight insertion to complete the HE lens and fissionable core. Appears insertion through the rear tail section. Note diagrams on walls too #Nukes #chinese #atomicpic.twitter.com/kuqbCBpiKx

      I suspect the diagrams may have zero to do with the reality of their bomb... one on the left looks like a common (not realistic) depiction of a gun-type weapon. Drawing of casings reminds me of Soviet public descriptions (again with no base in reality):http://blog.nuclearsecrecy.com/2012/02/17/friday-image-nuclear-bombs-soviet-style-1958/ …

      Oh, was thinking it was implosion weapon with piece missing for insertion. Guess I’m reading way too much into their diagram. The rear does appear to having a opening. Here is the US diagram of insertion was thinking as basis of design.pic.twitter.com/MpnjiQgDyb

      I mean, it may or may not use some kind of pit separation, who knows. I just wouldn't look to museum diagrams for insights into actual weapons — it's generally unlikely that people with knowledge of the weapon innards were involved in the creation of museum diagrams,

      and even less likely that people who DID have that knowledge would depict it very accurately ("official" depictions of weapon concepts for the public tend to be more unrealistic than "unofficial" ones) — compare Glasstone (official) with Hansen (unofficial)pic.twitter.com/AkqneQAdHr
