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.

Aight, so you seem very knowledgeable about niche air craft, so I have a pointless question for you...

What's the aircraft that most makes you wonder how tf it even flies?

Ahahaha.

Ah.

Well, the actual honest answer is that I've twice seen a quite large, hovering, silent, large equilateral triangle shaped craft.

The greenish, lower left pic is pretty much exactly what I've seen, twice, over the course of 10 years, around Seattle.

The second time I saw it, I was going across the West Seattle Bridge, and saw it hovering, only a few hundred feet over a hangar or some large byilding in Boeing Field, on the west side of Marginal Way.

Ironically, on the other side of the road as the Flight Museum where the extant M21and D21 are on display.

I do not purport to have any fucking clue how this thing works, but I have definitely seen it twice.

So yeah that's my actual answer, I've twice seen something that is apparently called the TR 3B sometimes 'Astra', sometimes 'Black Manta'. I have no idea why it has that name, if thats even kind of accurate to anything... but yep... giant (by normal aircraft standards), black, silent, hovering, equilateral triangle, with a large glowing area in the center, and 3 different glowing areas just inside of the uh, tips.

The second time I saw it, it was close enough that I could see red / green running lights on it... so ... my assumption is that it is some kind of human, experimental aircraft.

Military.com says, unofficially, that it ... well here:

https://www.military.com/video/aircraft/military-aircraft/tr-3b-aurora-anti-gravity-spacecrafts/2860314511001

It doesn't exist officially. It uses highly pressured mercury accelerated by nuclear energy to produce a plasma that creates a field of anti-gravity around the ship. Conventional thrusters located at the tips of the craft allow it to perform all manner of rapid high speed maneuvers along all three axes. Interestingly, the plasma generated also reduces radar signature significantly. So it'll be almost invisible on radar & remain undetected. This literally means that it can go to any country it likes without being detected by air traffic control & air defence systems.

?????

So anyway this would be the thing that I have no idea how it flies.

... Would you believe my cousin actually used to work SkunkWorks, before moving over to BlueOrigin?

Ah... everybody just calls me crazy.
