Northrop's UUV is doing its solo trials. So far there's this youtube video. They show the screw for the first time, I think. https://youtu.be/Qj-uu-Nbyhs

the screws are on the wings for all to see. nothing secret here. i recall the smaller model having two on each wing.

wonder if this thing can be airdropped..
looks like it might actually be able to sail down relatively safe.. handy for chink war, some can move under their own power and others can be dropped close, then wank at the bottom waiting for ships to move.
>>
>>62869793
they should make an armed version with a couple of belly torp tubes, for torps or captor mines. passive sonar is generally good enough to identify enemy subs and ships, so it could work.
>>
>>62870017
Ye and start parking em in the south china sea.

This type of drone is the perfect use of that massive 3d printer the Army has.
>>
>>62866519
It's not the primary means of propulsion, also these are supposed to be attritable platforms.

Doesn't need to be nuclear capable,
Its meant to take out nuke carrying gears.

what
>>
>>62873233
The prop is cavitating. It's a stand-in, not the real prop.
>>
>>62874315
lmao no, this is just the best Northrop can do. this thing is loud as fuck and is easily detectable by Chinese subs
>>
>>62874315
They keep showing close ups of it too, but i cant see it on any images of the ray. My guess is some sneaky internal propulsion system.
>>
>>62875503
Can't they just be swappable props for testing? At around 1 minute it looks like it's in the right place.
>>
>>62877018
I mean the props are small enough they could probably replace them relatively easily to find the best final outcome.
>>
>>62874315
It's at the surface, you fucking idiot. Of course, it will slightly cavitate, at max RPM when the pressure acting on the prop is low. Holy shit you faggots are actually retarded.
>>
>>62863560
>stupid shit like this
But imagine a manta ray drone doing a suicide run at a docked Chinese warship.
>>
>>62877509
I wasn't even gonna bother saying anything, honestly. "It's cavitating" when you can see through the surface...

It's evidence to support my argument, you seething brainlet shitskin. Spend less time scamming, lying, and seething and use it to learn something so you don't always look retarded every time you decide to vomit something out of your low IQ worthless cocksucker.

Anon says: "It's at the surface[,] of course it will slightly cavitate, at max RPM when the pressure acting on the prop is low."

You link: an introductory video that immediately performs a demo of cavitation increasing in inverse proportion to ambient pressure, simulated by reducing the height of a water column above a hydrofoil with a sluice gate. This demo is immediately followed by another demo showing the effects of a dive on a submarine prop (again, cavitation inversely proportional to ambient pressure). Your video is not in any way disagreeing with anon.

I say: your link is not an argument, because it flatly isn't. Whatever argument you would like to make, it hasn't been made.

You reply informing me that I'm a seething brainlet shitskin, and you attach a gif that you resaved from /pol/ to really make sure I know that I'm btfo.

Do you feel like I've been btfo, my child? Come to jesus.

>>62882447
Are you too retarded to see I replied to my own fucking post to give evidence to my own argument?

>>62882521
Why would anyone think that? You replied over a day later and you didn't even reply to the guy. It looks like him replying to you.

People don't magically know what you're trying to communicate. You have to communicate it.

Because they're not retarded? They would watch the vid and see it supports the post I replied to (my post). Doesn't matter if I replied a week later, anyone with a brain can see what it is.

stop shitting up my thread with your slapfight. we need someone with UUV propeller autism to tell us what we're looking at, not a list of anon's STDs.

It's just a regular ass boat propeller. Likely just for a bit of steering and low speed maneuvering / station keeping.

The actual primary propulsion method is variable propulsion, which is why it's a wing shape - it literally is a glider.

https://en.wikipedia.org/wiki/Underwater_glider

DARPA renders show it without the propellers. That might just be because it's a quick render or it might be DARPA doing crazy darpa shit and aiming for the moon with some exotic method.

picrelated, they propose to make it have a deployable generator. I'm guessing the idea is to have it function similar to a ram air turbine, only powered by ocean currents.
>>
>>62874328
lol. What do you want the Chinese to think?
These are going to be kabooming Chinese surface ships in large numbers.
We need the to underestimate us.
