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. Random twitter and YouTube comments belong in the Low Hanging Fruit thread.
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 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. These include Social media screenshots with a title punchline / no punchline, recent (after the start of the Ukraine War) reposts, simple reaction & template memes, and images with the punchline in the title. Put these in weekly Low effort thread 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.

The mass to orbit isn't the hard part. A reusable Falcon 9 can put 18,400 kg in low Earth orbit. That should cover two rods, plus hardware to hold and deploy them.
And then you would either need to wait for your satellite to get over the target, or add a lot more weight to maneuver it to the target.
If you add wings for precision you are adding drag and heat, both sapping from your destructive power.
If your weapons satellites all start maneuvering to cross your opponents' cities then they probably would have a bit of a warning that you are planning something, and likely just shoot them down at a much cheaper cost. Anti satellite missiles have been shown to work, and it would be easy to overheat a satellite with lasers.
You also have to contend with them just nuking you in response. If Moscow were to be destroyed in a single blast they would not wait to determine if it was nukes or something else, they would fire.
You can definitely make some stealthy satellites.
I was thinking for release you could actually fold out wings/parachute to increase drag so it would deorbit faster and with less propellant.
Don’t think you can target a satellite with a laser, it’s too far away and you’d have to find it first.
But overall it doesn’t seem particularly efficient or useful.
