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.

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