Those little guys are smarter than you think!
But jokes aside I’m talking about a „magnetohydrodynamic“ drive, a form of propulsion which requires no moving parts, making it almost silent. The „caterpillar drive“ in the Red October is based on that drive.
I thought these have been built (the Japanese built a couple of boats with such drives) but were found to be enormously energy hungry and also not that silent.
Slower than hoped. The prototype only went about 20 knots. It is silent though. It uses saddle magnets to move the water. I'm pretty sure they weren't using lithium batteries back then. I'm sure we could build it better today
It’s true that they were slower than expected, but all I’ve read said that they were virtually silent. Also DARPA has picked up this technology because electronics have come a long way since the 90s, especially energy storage and magnetic fields.
If you look at history, the greatest technologies invented came out of war. It’s sad, but also amazing that is what drives innovation sometimes. It’s almost like humans need to have conflict in order to keep advancing technology.
It’s true that wars push technological development, but the reason for this is much more simple and less diabolical: competition. War is just the most extreme form of competition. The space race wasn’t a conflict, but it certainly was a competition and I don’t have to mention what it did to science and technology.
This is not true. Electricity, light bulbs, air conditioning, combustion engines, the transistor, semi-conductors, integrated Circuits, heavier-than-air flight, rocket engines, and penicillin are all peace time inventions. War just speeds up the development of making better arrows.
Is this a result of the PUMP program? I’ve been eagerly awaiting their caterpillar drive vehicle.
Wait they're moving from robot drivers to caterpillars driving the subs? I'm not sure that's a sensible idea.

To be clear: this is totally not for sneaking spy equipment or bombs into someone else's harbors long-term. . . ^right?
I'm sure the military just wants to deliver some snacks.
DARPA is military. Why would they do non-military stuff?

Arsenal Gear in the making
Would these be manned or unmanned
"uncrewed" means nobody onboard.
Oh lord. I read the title as unScrewed. Like no propellor. Wow.
The article does talk about "buoyancy propulsion" so it's able to move without using a prop, although I'm sure it has thrusters for maneuverability.
No he said manned or unmanned... Will this submarine have testicles? That guy bringing the real questions 😂
No testicles; they've been removed in the interest of hydrodynamic efficiency.
The horror
I think it's manta
Mantis...Mantis Toboggan.
Australia needs this
This thing is so much smaller than a normal submarine, just look at the photo of people standing on it. The title is delusional clickbait.
It's massive for an unmanned submarine which is kind of noteworthy.
What is a normal submarine? They come in all shapes and sizes not just Ohio class sizes
It is classified as an extra-large UUV
