Sorry for going on about the fat man in the mirv thread...I haven't seen it in use...I should probably youtube it. But it does seem pretty...easter-egg-y.
Now for some somewhat more serious replies:
ShatteredJon
Nukes aren’t the only thing that makes would-be mushroom clouds…this is supposedly a 0.75 ton TNT Equivalent bomb (this is pure chemistry tho):

That kindof sortof looks a little like this:

Only, it appears the Fat Man is even smaller than 750kg of TNT equivalent.
But if you compare these to “real” mushroom clouds, it’s obvious that the bigass nukes make mushroom clouds that are completely different from both of these. To be fair, I haven’t played around with the fat man myself, so maybe I’m watching too many videoes =P
As for plausibility:
http://en.wikipedia.org/wiki/W54
This thing went down to 10T, and my other quote says that yeilds can go below 1 ton TNT equivalent. Again, I’m no physcisist, but it seems to me that a 1T TNT Equivalent bomb would be lighter than a 10T bomb…and the 10 T bomb is 27 cm’s in diameter and weighs 23 kg. Seems like a power armored fellow would be able to carry it just fine – and with the advancements we’ve since made in capacitors and chemical explosives as well as weapon design, I bet you could trim a lot of that weight off; again, as far as I understand all you need to do is bring some fissile material to a high enough density, and keep some deuterium and triterium inside the middle of it, and you have a fusion assisted fission explosion, which is what the W54 does.
If modern technology allows you to make the stuff more dense (requires closely timed explosions, therefor chemicals and capacitors need to be exceptionally advanced), then modern technology allows you to have less fissile material in a bomb, and therefore it can be lighter…unless I’m misunderstanding something.
http://en.wikipedia.org/wiki/Critical_mass#Critical_mass_of_a_bare_sphere
According to this, some materials have a very low critical mass. And this is without assisting with fusionable materials in the middle for extra neutrons, which is the trick used in the W54…it also doesn’t take neutron reflective materials into account, nor high pressure.
But I don’t know if the explosion could go all the way down to 250kg or perhaps 500kg TNT equivalent…and the fat man in the game appears to be no more powerful than that, at most.

That’s a good point – and I can’t do the calculations myself because even if I looked everything up I wouldn’t know if I did it correctly. Which is why I hope someone in one of those former cycles did it; it seems like this argument always has the same outcome – and if someone who has read those arguments can point me to it, I’d love to read them! (…searching hasn’t done me much good, though it might just have been bad luck or poor search skills on my part…)
“That said, why would you ever make a 1 ton nuclear bomb?”
I don’t know about you, but if I had to bring down a 10 stories tall building filled with angry Chinese soldiers, a 1 ton TNT equivalent nuclear bomb seems like a really easy way to do it if I have to do it on my own.
“Also, why would you arm infantry with such a weapon when the same effect (minus the nasty radiation) could be achieved with cruise missiles, bombs dropped from planes, or an armored weapons platform?”
In conventional warfare, I agree completely. If you’re able to use the Colin doctrin, you don’t want to use this. But Mr. Powell’s doctrin is unfeasable in conflicts involving superpowers. The Davy Crocket was deployed during the cold war, and assigned to infantry in western Germany because the USSR had a lot of scary tanks, many many more (and likely supperior) compared to those of a combined Western Europe. And someone thought that if the Reds decided to attack, we would not necessarily have air supperiority.
While the Davy Crocket might not be able to take down the tanks themselves (or they might…who knows, there’s so little info on those things…), it would definitely be able to destroy supply convoys and bridges. Deploying armor divisions rapidly opens a vulnerable flank in your forces: the enemy can utilize war of attrition.
In Fallout we don’t know if the Chinese armies outnumber the US armed forces; we don’t know if they have a lot of carriers and aircraft. In my mind, those two would be valid excuses for deploying a device like the Davy Crocket, because infantry is useful even if you don’t have air supperiority.
But we don’t know these things, so that’s pure speculation.
What we do know is that resources are supposed to be really scarce. What we do know is that attrition warfare seems to be a really good idea if you can pull it off in a situation like that. Cue a squad of power armored dudes where one has a foldable magnetic catapult and a mininuke, and one of the others has 2 mininukes. Drop them down in parachutes somewhere nasty, or get them ashore from a submarine, something or other, but deploy them behind enemy lines and grind their war machine to a halt.
What you don’t do is drop a pickup truck with a parachute and 1 ton of TNT loaded into the warzone because you’re afraid of nuclear fallout.
This part of it, I don’t really see how you can question – in Fallout, in the war between the US and China, a 1ton infantry weilded nuke would be useful.
The question is, to me anyway, is such a device plausible or not. And would it be useful after 200 years, and looking like what the fatman looks like?
