It's the dunk tank.
This is where you come to post big-brained hot takes by chuds, libs, or even fellow leftists, and tear them to itty-bitty pieces with precision dunkstrikes.
Rule 1: All posts must include links to the subject matter, and no identifying information should be redacted.
Rule 2: If your source is a reactionary website, please use archive.is instead of linking directly.
Rule 3: No sectarianism.
Rule 4: TERF/SWERFs Not Welcome
Rule 5: No ableism of any kind (that includes stuff like libt*rd)
Rule 6: Do not post fellow hexbears.
Rule 7: Do not individually target other instances' admins or moderators.
Rule 8: The subject of a post cannot be low hanging fruit, that is comments/posts made by a private person that have low amount of upvotes/likes/views. Comments/Posts made on other instances that are accessible from hexbear are an exception to this. Posts that do not meet this requirement can be posted to !shitreactionariessay@lemmygrad.ml
Rule 9: if you post ironic rage bait im going to make a personal visit to your house to make sure you never make this mistake again

So am I missing something fundamental? Silent or stealth supercavitation propulsion seems extremely difficult just by its nature of creating constant explosions lol, but I am a complete layperson. I did read the take that it could be considered stealth by virtue of simply moving fast enough to use its own propulsion signature as a mask? Genuinely curious, the project sounds really cool
Isn't the point that this is removing all moving parts of the submarine? No mechanical pieces, no engine (it's nuclear), no propellor, no jet. Replaced with laser.
It won't be completely soundless, you're always going to make some sort of sound based on displacing water. But any reduction on existing methods is going to make objects that are already incredibly hard to detect even harder.
That's what I thought as well, I just wasn't sure if it balanced out against a cavitation based propulsion system - maybe it does(!), but idk lol. I just assumed it would be relatively easy to detect via sonar but with a very different profile obv.
Edit*: then again, we are comparing the volume of cavitation vs a conventional submarine drive system. Could very well be that the conventional engine with more moving components is just straight up louder than bubble explosions >.>
