A "Showerthought" is a simple term used to describe the thoughts that pop into your head while you're doing everyday things like taking a shower, driving, or just daydreaming. A showerthought should offer a unique perspective on an ordinary part of life.
Rules
- All posts must be showerthoughts
- The entire showerthought must be in the title
- Avoid politics
- 3.1) NEW RULE as of 5 Nov 2024, trying it out
- 3.2) Political posts often end up being circle jerks (not offering unique perspective) or enflaming (too much work for mods).
- 3.3) Try c/politicaldiscussion, volunteer as a mod here, or start your own community.
- Posts must be original/unique
- Adhere to Lemmy's Code of Conduct

Thanks for answering seriously even when I didn’t.
Interesting that they are quieter! I never would’ve guessed that. Thanks for sharing.
I think the old ones are loud, but newer ones can be really quiet. IRC Sweden had one that did well in war games. Gotland class. France also has really modern ones.
Basically they chugachugachugachuga, then go into battery mode and dissappear off sonar. Range is low obviously. Batteries don't last that long.
Don't think the Russians have those though. Their navy has been a joke for over a century.
Range is infinitesimal comparatively. A nuclear submarine can operate continuously under water for 6 months. An old diesel sub needs to resurface after something like 12-18 hours.
