A community for your defence shitposting needs
Rules
1. Be nice
Do not make personal attacks against each other, call for violence against anyone, or intentionally antagonize people in the comment sections.
2. Explain incorrect defense articles and takes
If you want to post a non-credible take, it must be from a "credible" source (news article, politician, or military leader) and must have a comment laying out exactly why it's non-credible. Low-hanging fruit such as random Twitter and YouTube comments belong in the Matrix chat.
3. Content must be relevant
Posts must be about military hardware or international security/defense. This is not the page to fawn over Youtube personalities, simp over political leaders, or discuss other areas of international policy.
4. No racism / hatespeech
No slurs. No advocating for the killing of people or insulting them based on physical, religious, or ideological traits.
5. No politics
We don't care if you're Republican, Democrat, Socialist, Stalinist, Baathist, or some other hot mess. Leave it at the door. This applies to comments as well.
6. No seriousposting
We don't want your uncut war footage, fundraisers, credible news articles, or other such things. The world is already serious enough as it is.
7. No classified material
Classified ‘western’ information is off limits regardless of how "open source" and "easy to find" it is.
8. Source artwork
If you use somebody's art in your post or as your post, the OP must provide a direct link to the art's source in the comment section, or a good reason why this was not possible (such as the artist deleting their account). The source should be a place that the artist themselves uploaded the art. A booru is not a source. A watermark is not a source.
9. No low-effort posts
No egregiously low effort posts. E.g. screenshots, recent reposts, simple reaction & template memes, and images with the punchline in the title. Put these in weekly Matrix chat instead.
10. Don't get us banned
No brigading or harassing other communities. Do not post memes with a "haha people that I hate died… haha" punchline or violating the sh.itjust.works rules (below). This includes content illegal in Canada.
11. No misinformation
NCD exists to make fun of misinformation, not to spread it. Make outlandish claims, but if your take doesn’t show signs of satire or exaggeration it will be removed. Misleading content may result in a ban. Regardless of source, don’t post obvious propaganda or fake news. Double-check facts and don't be an idiot.

Uh, maybe I'm unfamiliar with the engineering behind nukes. Do they expire? Or are you joking that they've just stripped the parts?
Honestly mostly just the latter. Was joking that they would've maintained them so badly that none of the nukes would make it out of their silos, even if they were still capable of detonation.
While I was aware the warheads require maintainance, @impairedimperator@lemmy.zip definitely said it better than I could.
They do expire. Problem is that there's a lot of them. Fire 100 nukes, and even if 99% fail, that's at least one mushroom cloud in the most fertile land on earth. And the ones that did expire become essentially dirty bombs.
That's pretty much why I was asking, I figured that no level of neglect would make one of these not dangerous. Which also makes it pretty clear that someone who's so comfortable with their use is likely confident that they would not be victims of that use.
Neglect measured on the scale of centuries might make them effectively safe...you need to have all the conventional explosives in the implosion shell fail to explode. If some of them fail, you likely won't reach criticality in the warhead itself, in which case you just detonated a regular bomb that had enriched uranium shrapnel.
That being said, most modern explosives become less stable and more sensitive over time, not inert. So the implosion timing is gonna be off, which means no criticality. Just spreading radioactive material.
Do you have a source to read further on this at all?
Umm. Not really? I'm kinda pulling together basic implosion-type nuke design, where you have a nuclear core surrounded by conventional shaped charges that are supposed to detonate and compress the nuclear core just prior to the nuclear reaction.
As you would expect, most governments are a bit touchy on details about military explosives that they use...I just happen to have done a decent amount of explosives R&D in the past. Picked up a few things.
How interesting! Can you tell me how one would theoretically build a cobalt bomb inside their garage...for educational purposes of course.
/j and in Minecraft
I don't want to get banned for trying to do warcrimes again.
You probably won't be able to get enough material for a true cobalt bomb.
What you could do, however, is build a Farnsworth fusor. That's very doable in a basement using...relatively easily acquired parts. As long as you keep the operating voltage under 30kV you won't need lead shielding, but you won't be getting many neutrons either. Get a couple plates of lead, get yourself a bunch of cobalt salts (ask someone that does glass art) and put them in the reactor chamber. Then crank that bitch up as high as your transformer will let you, and soon you'll have radioactive cobalt. Then you go to a gun store and buy a block of tannerite, US gun culture makes this a commonly available explosive, and tape the cobalt to it.
Now you have a salted dirty bomb.
If you're feeling really lucky, you could try modifying a time-of-flight mass spectrometer to integrate into your reactor chamber vacuum output, allowing you to collect reasonably pure tritium in tiny amounts. Get enough of that, add some deuterium, figure out a way to ignite it, and you have a thermonuclear device.
Edit: if you manage to pull off any of this, that will be impressive. Reach out to your local university, and collect an honorary degree in mechanical, electrical, or nuclear engineering.
