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.

Wouldn't this be very easy to defeat with just a star chart? If they were also able to remove stars from view, sure, I might get where you're going with this. But adding extra stars? That's just noise that can be ignored if you know what the stars are supposed to look like. Match up existing stars with yesterday's chart and anything that doesn't appear on the chart is discarded.
I dont know where the cuting edge startracker tech is nower days, but in the first cold war this stuff was borderline analog. Basically lining up some light sensors with tubes on them into the position of the stars u wanted to track. If then lets say one star turns into 2 stars (one is just a reflection of a sat) then the chance of fucking up tracking could be 50/50.
But yeah today theres gona be probably 3-12 cameras and some digital wiz calculations, but i doubt that most legacy ICBM systems are upgraded to that.
If we are talking realistically, star trackers in space are just good for orientation data, not position. Modern ring-laser gyros have low very drift rates. ICBM flight times are short.
Assuming the military cares to retrofit a modern IMU, I doubt a star tracker is the least bit necessary for a good navigational fix.
