I read that as &quot;Manta Ray Unscrewed ...&quot; and could not process the rest of the sentence.<p>Are manta rays attacking underwater vehicles now?

I was wondering how this UUV was powered and all that DARPA was willing to divulge was &quot;Novel energy management techniques&quot; and &quot;undersea energy harvesting&quot; [1].<p>Anyone have any insights?<p>[1] <a href="https:&#x2F;&#x2F;www.darpa.mil&#x2F;news-events&#x2F;2024-05-01" rel="nofollow">https:&#x2F;&#x2F;www.darpa.mil&#x2F;news-events&#x2F;2024-05-01</a>

Sounds like they are using a [Buoyancy_engine](<a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Buoyancy_engine" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Buoyancy_engine</a>). The large wings are there to provide efficient forward motion when going up or down the water column.

I feel like at some point, UUVs will be able to disable one part of the nuclear triad. A submarine with nuclear warheads is such a big ticket item that no country can reasonably have a lot of them. The US has 14, Russia 11. The entire world fleet is probably in the 30s.<p>A UUV that can find one and follow it indefinitely could be able to neutralize it and would be, presumably, much cheaper and easier to build. How hard could it be to eventually find and track every ballistic missile submarine with them?<p>I’m sure there are things I’m not understanding (how communications work, whether such a sub would be able to launch ICBMs even after being torpedoed, etc.) but it seems like this should have major strategic ramifications eventually.

There was a giant NOTAM in the pacific a few weeks ago. The title of the TFR was &quot;MUTANT MEGALODON&quot;. A1396<p>I am curious if these two things were related.

Biggest issue for AUVs is how water attenuates radio, meaning this will have to surface to phone home. Guessing it will mostly be used for surveillance.

Carrier Command (1988) can finally be a reality:<p><a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Carrier_Command" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;Carrier_Command</a>

Saw the headline, immediately thought of Voyage to the Bottom of the Sea with Seaview and the smaller Manta craft.<p>Fewer humans onboard though...

I wonder why it needs wings underwater.

I always wonder how these aircraft deal with sea life and debris. The first 0 to 20 meters of sea is the most dense populated zone in the world. How do you deal with collisions? I think therefor this will never be a success.

&gt; Manta Ray vehicle being towed in preparation for testing<p>Find it funny that they have to tow the prototype for some reason. Good to know DARPA also releases half-done prototypes.<p>Lighthearted fun this morning, and not to be taken serious.

Why it needs vertical control surface? Why manta ray don&#x27;t need one?

UUV (Uncrewed Underwater Vehicle) is a meh acronym. CrewL(l)ess Underwater Boat would&#x27;ve given them CLUB or CUB!

Not really drone-lego yet, but at least partially modular..
