A community for your defence shitposting needs

Rules

1. Be niceDo not make personal attacks against each other, call for violence against anyone, or intentionally antagonize people in the comment sections.

2. Explain incorrect defense articles and takes

If you want to post a non-credible take, it must be from a "credible" source (news article, politician, or military leader) and must have a comment laying out exactly why it's non-credible. Low-hanging fruit such as random Twitter and YouTube comments belong in the Matrix chat.

3. Content must be relevant

Posts must be about military hardware or international security/defense. This is not the page to fawn over Youtube personalities, simp over political leaders, or discuss other areas of international policy.

4. No racism / hatespeech

No slurs. No advocating for the killing of people or insulting them based on physical, religious, or ideological traits.

5. No politics

We don't care if you're Republican, Democrat, Socialist, Stalinist, Baathist, or some other hot mess. Leave it at the door. This applies to comments as well.

6. No seriousposting

We don't want your uncut war footage, fundraisers, credible news articles, or other such things. The world is already serious enough as it is.

7. No classified material

Classified ‘western’ information is off limits regardless of how "open source" and "easy to find" it is.

8. Source artwork

If you use somebody's art in your post or as your post, the OP must provide a direct link to the art's source in the comment section, or a good reason why this was not possible (such as the artist deleting their account). The source should be a place that the artist themselves uploaded the art. A booru is not a source. A watermark is not a source.

9. No low-effort posts

No egregiously low effort posts. E.g. screenshots, recent reposts, simple reaction & template memes, and images with the punchline in the title. Put these in weekly Matrix chat instead.

10. Don't get us banned

No brigading or harassing other communities. Do not post memes with a "haha people that I hate died… haha" punchline or violating the sh.itjust.works rules (below). This includes content illegal in Canada.

11. No misinformation

NCD exists to make fun of misinformation, not to spread it. Make outlandish claims, but if your take doesn’t show signs of satire or exaggeration it will be removed. Misleading content may result in a ban. Regardless of source, don’t post obvious propaganda or fake news. Double-check facts and don't be an idiot.

Look. Just because people hope to not see it and actively avoid looking in the general direction of, does not make the cyber truck invisible.

Oh, if only... If then the owners could be invisible too... One can dream

Sucking up to Putin. The next thing he will say is all 2 su57s in existence are much more advanced.

He has Tesla's "Full Self Driving" system, which works with AI and cameras.
He probably wants to just upload his software to US fighter jets for, say, $20 million per unit.

Hopefully not the same elementary AI and cameras as the Tesla's. The missiles would be aiming for barricades on the highway

His fucking obsession with computer vision. He’s so convinced he’s right he forgot that clouds exist… and his cars plow straight into obstacles.

[–] [email protected] 30 points 2 days ago (1 children)

Yeah, the "lidar is useless" guy whose cars are consistently crashing into things when visibility is bad is telling us that he can do the same thing with missile targeting systems... Sounds like a great idea

My friend bought a red car specifically so it could be seen by Tesla's cameras.

[–] [email protected] 4 points 1 day ago

I have bad news for him. They can't see firetrucks reliably.

[–] [email protected] 2 points 1 day ago* (last edited 1 day ago)

No no. See guessing objects from flat images is much better than using math and lidar. Especially if you may have a flawed llm model.

Given how advanced our math and knowledge of radar is, it is literally stupid to use them.

See, those, radar, lidar and math give you a 3d objects.

Oh, wait. It is the other way around.

Wouldn’t matter for IR vision, which the F-35 already has.

[–] [email protected] 28 points 2 days ago (1 children)

And that a plane at altitude is too small for wide field cameras which means scanning the sky with narrow fov detectors.

[–] [email protected] 12 points 2 days ago (1 children)

And F-35s are really fast. By the time you recognize and can target it, it'll fly behind a cloud or something. So not only do you need to make a really fast rocket w/ vision-based AI integrated, it also needs to be able to detect said plane at great distances, as well as maneuver well enough to see it as it exits clouds and whatnot. That's a lot more complicated than slapping radar on something with heat tracking at close distances.

Guy whose cars run into stopped fire trucks thinks he’s an expert on computer vision.

[–] [email protected] 20 points 2 days ago

It is especially important to understand that Tesla's struggles with navigation are entirely a result of Elon refusing to equip them with LiDAR. This isn't some "The tech is really new and really complicated and we're still figuring it out" problem. There is a very good solution to most collision avoidance scenarios, but Elon refuses to let them use it because he's an idiot.

[–] [email protected] 104 points 2 days ago (2 children)

Someone died because one of those cars thought the broadside of a white semi trailer was the sky and drove under it

For those doing the maths at home:

An F35 who obligingly flies top-towards-you (not exactly something you can do, but hey, maybe they're turning) is all of 10m tall.

An AIM-120C can very comfortably hit a target at 100km.

At that range, the F-35 takes up 26 arcseconds, or 0.007 degrees. That's roughly about the size of this period, at a distance of 3 meters away.

[ . ]

Good luck spotting that in a sky of roughly the same colour, full of other objects.

[–] [email protected] 75 points 2 days ago (1 children)

You can place cameras anywhere, they don't need to be right next to what is being targeted. Nearer ranges will allow AI to misidentify at much higher rates than max standoff ranges of an AIM-120C.

[–] [email protected] 46 points 2 days ago

I don’t think you were getting enough credit for ‘misidentify’.

Can't these things aerosolize you from beyond the fucking horizon? How helpful are those AI powered low light cameras when they're phase transitioned by a missile launched from a hundred miles away?

[–] [email protected] 19 points 2 days ago (3 children)

You'd need a camera network spanning the entire battlefield. And it'd need telephoto lenses at the very least, because stealth fighters are high and small. And it'd need to stay connected after an initial missile exchange.

I don't buy for a moment that nobody in the Pentagon has thought of this, and explained why it's not a dealbreaker in a classified report.

[–] [email protected] 1 points 6 hours ago (1 children)

BVR and over the horizon radar has been around for decades.

[–] [email protected] 1 points 1 hour ago

We're talking about stealth jets here, though...

They don't give much of a conventional radar return. Which is why Musk even brought up his definitely-new definitely-original idea.

Sir, our air defence is down!

Is it hackers?

No sir, it's cloudy.

[–] [email protected] 144 points 2 days ago (3 children)

If a fighter jet is within visual range of a camera, it's already too late. And that's if there aren't any clouds.

In the long term maybe he has a point. In the short term the other guys are often using a radar built in 1985 and displaying to a ray tube.

[–] [email protected] 8 points 1 day ago (2 children)

But also, how far can low light sensitive cameras see into the sky? Maybe a couple miles with some sort of telescopic optics? The F35 can attack from beyond visual range using its 100 mile range radar system.

[–] [email protected] 1 points 1 day ago* (last edited 1 day ago) (1 children)

Up to the horizon (and actually slightly past due to lensing). The setting sun is a perfect example. Sure, it's brighter than a single fighter aircraft, but as long as you have double digit individual photons to work with the game hasn't changed theoretically, and light collection technology is right around perfect at this point.

Continuous cloud cover messes up that calculation pretty good, though. If this kind of system was seriously deployed today we might see pre-WWII tactics and strategies coming back to exploit that. In practice, sensor fusion in all kinds of bands is the name of the game, and what will probably make stealth aircraft obsolete eventually.

[–] [email protected] 2 points 23 hours ago

Sensor fusion is another F-35 feature. Elon seems to think visible spectrum cameras are all you need. Even if you could capture a couple dozen photos reflected off a fighter jet from miles away, how could you reasonably know it's speed, distance, and location like you get with radar?

[–] [email protected] 1 points 1 day ago (1 children)

How big of an area of the sky is that going to cover? And clouds?

[–] [email protected] 1 points 1 day ago

Sky coverage is just a matter of replicating one telephoto unit a couple hundred times or whatever to cover the horizon. Clouds are a game-breaker in the optical frequencies - when they're there.

[–] [email protected] 6 points 1 day ago (1 children)

Yeah, while we are at it. Everything sucks compared to the starship enterprise. You can't beat photon torpedoes and shields. All current military technology sucks.

[–] [email protected] 2 points 1 day ago

Elon Musk's next idea is to just power everything with fusion. It's easy! There's deuterium everywhere!

[–] [email protected] 30 points 2 days ago

He's just a dumb attention seeker. Of course he's gonna shit on the most over-engineered thing in existence. Tho the context of the shitty engineering his companies do makes this even funnier. What a loser.

[–] [email protected] 44 points 2 days ago (2 children)

"laughably easy to take down fighter jets"

yeah all you have to do is ban the kid running the elon jet twitter. Seems easy enough to me.
