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.

It doesn't even make sense. Hypersonic missiles are good at being hard to take down themselves. But you don't need that to take down an aircraft. You need super sensitive radar systems, since the claim is that these aircraft reflect about as much energy as a bumblebee would.

these aircraft reflect about as much energy as a bumblebee would.

That is truly amazing.

[–] [email protected] 21 points 11 months ago (3 children)

Do note that the this claim comes from the same people who don't hand out any actual specs and always fly with an additional reflector. The latter makes it easy for radars to see them again. This is helpful in allied airspace, but it also makes it impossible to verify the claim.

Also note that modern radars are sensitive to how fast an object approaches (or leaves) the radar. Bumblebees don't break the soundbarrier usually, so it is possible to see these planes, but you do have to tweak your radar for it. (Hence why the US doesn't give specs.)

[–] [email protected] 6 points 11 months ago

So they just need to build an aircraft that moves at the same speed and height as a bumblebee. Bam ! Undetectable killing machine.

[–] [email protected] 5 points 11 months ago

You'd be surprised the velocity you get from the return on a bird's flapping wing. Also the Doppler ambiguity smears with SNR, so you'll see a bird as something moving between 30 and 300mph at the edge of sensitivity.

This how we get echolocating missiles.

[–] [email protected] 9 points 11 months ago (1 children)

Radar is echolocation with EM waves (low frequency light) instead of sound waves. And there are already plenty of radar guided missiles.

[–] [email protected] 3 points 11 months ago (1 children)

I meant to put ears on the missile. I'm sure the plane is still plenty loud.

[–] [email protected] 3 points 11 months ago (1 children)

That is called passive sonar. I suspect that it is kinda hard to hear from the missile. Anything behind you is certainly not hearable, since the missile goes faster than sound. I have no idea if you could measure the sound coming from the front. You also have to take into account that you are chasing an after image, since the plane is also faster than sound. But torpedoes use this, so the idea is valid.

[–] [email protected] 3 points 11 months ago

Those are likely quite valid points. This being noncredible defense they have no place here.

[–] [email protected] 5 points 11 months ago

Put a bat in the missile and let's give Project Orcon another go

[–] [email protected] 12 points 11 months ago

Buzzwords are all that matters.

Also, too much of a credible point.

[–] [email protected] 4 points 11 months ago (1 children)

Most state of the art SAMs are technically hypersonic.

[–] [email protected] 3 points 11 months ago

Interesting. I did not know that!

[–] [email protected] 2 points 11 months ago

It’s not that impressive… a bumblebee can emit the same small radar signature as well.

This is the propaganda way of saying "MY DAD CAN BEAT UP YOUR DAD!!!!!"

[–] [email protected] 1 points 11 months ago

And the funny thing is, both op and the newspaper in the screenshot are doing it!

[–] [email protected] 37 points 11 months ago (1 children)

Maybe. Maybe not. Maybe fuck yourself.

OMG, scary news. Time to increase the defense budget again, I guess…

Hypersonically it goes door-to-door knocking
"Any B-21's here? No, right then. On to the neighbors."

[–] [email protected] 6 points 11 months ago

I worked on the b-2 (has the same tech nearly). If you take a panel off to inspect anything or fix an issue the jet has to go to the paint shop to have the paint re-applied because its most of what makes it stealth. The paint absorbs radar.

Lets find out, these things armed with nukes vs China and their "hypersonic" missile

[–] [email protected] 2 points 11 months ago* (last edited 11 months ago)

The most bat shit insane part of this is the missile absolutely cannot maneuver to intercept at hyper sonic speeds unless it's a nuclear warhead. In which case, yes we know you can down a plane with a nuke.
