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.

What country has a "real army"?
Satellites, drones, and guided missiles all rely on radio emissions for command and guidance. Every ship in the carrier group, plus many dedicated aircraft have SIGINT and ELINT roles specifically dedicated to countering such threats.
While drones and guided missiles do pose a threat to a carrier, the carrier poses a much greater threat to anyone operating such drones and missiles.
Unless you have access to intelligence that you probably shouldn’t be sharing in an Internet forum, neither of us really knows what is needed to guide the missiles of our adversaries.
That said, my day job is a GNC engineer (guidance navigation and controls) for rockets and spacecraft. It’s absolutely possible to hit a carrier with no radio signals whatsoever
Carriers sounds as easy as some lemmy users moms
Just not as heavy.
I would rule out drones, as yep, if they are radio controlled, you can just blast them with jamming, but guided missiles are absolutely capable of sinking a carrier. The trick is that you need a shitload of them since the carrier group has both long-range missiles and short range CIWS systems to counter those missiles. The only way you can hurt a carrier with them is if you launch a shitton of them.
Or you can actually launch ballistic missiles instead of cruise missiles. The upside is that anti-missile missiles and CIWS are not quick enough to catch them and radars can't really see them if they are not Hamas-style homemade fireworks, but stuff like the Kinzhal. The downside is that it's very hard to guide it in the terminal stage, so they might come very fast, but may be very inaccurate.
If Russia's Kinzhal, or China's DF-ZF is accurate enough to hit a carrier, that's a big problem for the carrier. Whether it is accurate enough is a good question, since maneuvering something that is that fast is not easy, and also if you go that fast in our atmosphere, you are basically blind since the air gets turned into plasma around you (think Space Shuttle reentry). It is a hotly debated topic whether Russia's or China's weapons are accurate enough. OTOH, from the price of a carrier (not including the group or the planes or operation), you can build more than a thousand Kinzhals, so assuming you can launch them all, eventually it might hit something important.
Or you can also just build a diesel electric sub, get some cheap guided torps and torpedo the shit out of the carrier. There is ASW defenses of course, but Sweden has repeatedly demonstrated simulated kills on US carriers with diesel-electric subs.
Stupid actual question: Would a person with a scuba tank and nothing to live for be able to get close to one? I assume there's something looking for people swimming under the water, because if I can think of it, so can an engineer.
On the one hand, a carrier is fricking fast unlike its size would suggest, so good luck catching up. On the other hand, the ASW sonars may not pick up something as small as a diver, but they certainly can fry them.
Maybe in port.
I figured the easiest thing to do would be to keep moving.
