I know smth about this is fucking dumb, but no clue what. The added weight? The impracticality?

[-] mkwt@lemmy.world 40 points 10 months ago

Air is a compressible fluid. Water is incompressible. Energy from shock waves will be transmitted from the hull to the crew in a much more efficient fashion.

Wait, explain that to an idiot please. Could the water pressure crush a person? It wouldn't just go up?

[-] frostwhitewolf@lemmy.world 23 points 10 months ago* (last edited 10 months ago)

Because water doesn't compress it transfers any shockwaves straight through anybody who is in the water. This happens much faster than the water has time to move out of the way.

Sailors who are in the water after abandoning ship during naval battles are in extreme danger of dying if a bomb goes off close by.

[-] CaptnNMorgan@reddthat.com 7 points 10 months ago

So what exactly happens? The water moves into the person so fast it crushes them?

[-] Voroxpete@sh.itjust.works 13 points 10 months ago

Not exactly. The shockwave propogates directly into your body. Basically, the energy transfer liquifies your internal organs.

[-] JungleJim@sh.itjust.works 1 points 10 months ago

Since my answer seems to have been incorrect, can you help me understand how that's different from being rapidly and thouroughly crushed by the water the soldier would be submersed in? The water is the medium of the shockwave, so the energy crushes you through the force propagated through the water. No?

For some reason my post wouldn't post. Anyway, here's a video demonstration https://youtu.be/W4DnuQOtA8E

It uses balloons filled with water and air and small firecracker explosions to show how different the pressures on your body would be (especially organs like lungs, digestive tissue, which would have air/gasses in them).

Thank you for this, wild stuff

Tank get hole, water go out hole

Early warning of Hullfailure from smaller penetrations. Success again

[-] Lesrid@lemm.ee 3 points 10 months ago

Big two stick energy.

[-] dQw4w9WgXcQ@lemm.ee 4 points 10 months ago

Yeah, but then you're left with a lighter, more agile tank. It's a win-win!

A community for your defence shitposting needs

Rules

1. Be niceDo 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.
