NonCredibleDefense
A community for your defence shitposting needs
Rules
1. Be nice
Do 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.

Wow. Meet Your Macher
China's navy has apparently tested out a hypersonic rail gun — basically a device that uses a series of electromagnets to accelerate a projectile to incredible speeds — but during a demonstration of its power, things didn't go quite as planned.
As the South China Morning Post reports, the rail gun test lobbed a precision-guided projectile — or smart bomb — nine miles into the stratosphere. But because it apparently didn't go up as high as it was supposed to, the test was ultimately declared unsuccessful.
This conclusion came after an analysis led by Naval Engineering University professor Lu Junyong, whose team found with the help of AI that even though the winged smart bomb exceeded Mach 5 speeds, it didn't perform as well as it could have.
This occurred, as Lu's team found, because the projectile was spinning too fast during its ascent, resulting in an "undesirable tilt." Gun for Everybody
Successful or not, news of the test is a pretty big deal given that it was just a few months ago that reports emerged about China's other proposed super-powered rail gun, which is intended to send astronauts on a Boeing 737-size ship into space (NASA had begun building its own astronaut-shooting railgun in the 1990s, but had to abandon it due to lack of dinero.)
As with many space technologies, there's the propensity for some messy overlap with military tech. As such, news about the smart bomb rail gun test, which for the record did not make it all the way to space, could well freak out officials stateside.
Chinese officials, meanwhile, are paying lip service to the hypersonic rail gun technology's potential to revolutionize civilian travel by creating even faster railways and consumer space launches, too.
Despite the big promises of politicos, there are still lots of technical kinks that'll need to be ironed out before a giant rail gun is ready to shoot humans — or weapons — into space, not least of which the spinning and tilt issues demonstrated by the Naval Engineering University researchers in this test.

NASA wanted to shoot astronauts into space? Like going from 0 to 800+ mph in an instant type of shoot?
NASA's design is a few kilometres long and accelerates the vehicle at about 3 G up to roughly Mach 1. The technology is the same principle as a railgun, but it's more like a maglev train with a track that ends pointing upwards a bit
