FIRST OFF:
15kg is a FUCK TON of plutonium.
Bare critical mass of Pu239 sphere around 11kg.
THEY JUST CARRY IT AROUND IN 1 BOX!

3/n SECOND OFF: you DO NOT use 15 kilos of plutonium on a backpack nuke. Fat Man core was only 6.2kg ffs.pic.twitter.com/r9t1pwqbuP
FUN FACT: Davy Crockett, the closest thing to a "backpack nuke" in US arsenal, had a mere 1.6 kg of Pu + 2.42 kg of HEU. And now you know!
I knew about the 26ish pounds of HE but I gotta ask, where'd you pull the fizmat amounts from?
A very interesting document... that I will someday write about, or something...

That's well below critical mass. Would it need a huge neutron initiator to overcome lack of fizmat? I'm interested in that document...
But there are accounts of both US and Soviets having low-yield nukes with *even tinier* fuel loads, e.g. 0.8-2kg: http://russianforces.org/blog/2012/10/interesting_document_on_soviet.shtml …
