      The suns angular diameter is about 0.01 radian, so at a distance of 100km, the suns reflection will spread out to a disc about 1km across.

      392MW over a disc that size is 500w/m2, which is weaker than direct sunlight.

          And each one makes a 1km2 spot.

          It’s not the aiming, it’s that the sun is not a point source.

      Uh… losses from transmitting through the atmosphere a second time?

      Damn. I wonder what its operational range would be.

        this thing is big enough to alter the average reflective index of a whole state if it swings around its mirrors

        the focus spot in theorie could be set to any range, just as u go more far the precision of each mirror angle will be the limiting factor amongst atmospheric losses distortions.

          Even if the actuators had enough precision, which they almost certainly do not, there’s no way the mirrors are flat enough to keep the light collimated that far out. The angular spread would make the intensity much lower at orbital altitudes.

            True, however even if you get nearly 400MW of energy focused roughly, that’s going to be well outside the operating parameters of satellites. The only thing that would save them would be the fact that they’re moving at orbital speed and would only be subject to that beam for milliseconds.

          You can shoot a strong laser and use a super sensitive receiver to a very specific frequency

          That argument doesn’t hold up

          That is 300 ft, not 600-1,200 miles.

          The Sun puts more energy on a spy satellite than the array could do.

            The extra distance from the satellite to the earth and back is negligible. It’s also countered by having thousands of sources vs a single one.

            It’s why you can be blinded by looking at the sun a mirror still, it’s not like the mirror becomes the new source and the calculation starts again….

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.
