The rules for posting and commenting, besides the rules defined here for lemmy.world, are as follows:

Rules (interactive)


Rule 1- All posts must be legitimate questions. All post titles must include a question.

All posts must be legitimate questions, and all post titles must include a question. Questions that are joke or trolling questions, memes, song lyrics as title, etc. are not allowed here. See Rule 6 for all exceptions.



Rule 2- Your question subject cannot be illegal or NSFW material.

Your question subject cannot be illegal or NSFW material. You will be warned first, banned second.



Rule 3- Do not seek mental, medical and professional help here.

Rule 4- No self promotion or upvote-farming of any kind.

That's it.



Rule 5- No baiting or sealioning or promoting an agenda.

Questions which, instead of being of an innocuous nature, are specifically intended (based on reports and in the opinion of our crack moderation team) to bait users into ideological wars on charged political topics will be removed and the authors warned - or banned - depending on severity.



Rule 6- Regarding META posts and joke questions.

Provided it is about the community itself, you may post non-question posts using the [META] tag on your post title.

On fridays, you are allowed to post meme and troll questions, on the condition that it's in text format only, and conforms with our other rules. These posts MUST include the [NSQ Friday] tag in their title.

If you post a serious question on friday and are looking only for legitimate answers, then please include the [Serious] tag on your post. Irrelevant replies will then be removed by moderators.



Rule 7- You can't intentionally annoy, mock, or harass other members.

If you intentionally annoy, mock, harass, or discriminate against any individual member, you will be removed.

Likewise, if you are a member, sympathiser or a resemblant of a movement that is known to largely hate, mock, discriminate against, and/or want to take lives of a group of people, and you were provably vocal about your hate, then you will be banned on sight.



Rule 8- All comments should try to stay relevant to their parent content.



Rule 9- Reposts from other platforms are not allowed.

Let everyone have their own content.



Rule 10- Majority of bots aren't allowed to participate here. This includes using AI responses and summaries.

I've seen a few articles now that US fighter jets have kill switches in them, so the US could just render them useless for anyone they've sold them to.

Is this true? It sounds insane to me, I've always assumed that countries that buy these jets have full control over them. It's a gaping hole in your defence if you don't.

They don't need them.

Stop selling spare parts and they will soon be useless.

They are incredibly maintenance intense even in peace time. In wartime even more so because even minor combat damage adds up.

Iran bought 79 F-14 in 1974. Revolution and arms embargo 1979. In 1984 they had 15 airworthy planes kept in shape by taking parts from other F-14s.

They have since got some spare parts from hostage deals and the black market. Probably reverse engineering too so they have about 40 of them flyable. But the 5 first year has 80% of the fleet grounded should say something about it.

Turns out America's greateast weapoin in its fight against terrorism is the quality of its engineering.

I wouldn't expect jets from other countries to be any different. Aircraft in general get a lot of inspection and maintenance. Military jets planes push the limits of what their materials and systems can handle, and it takes a toll.

Idk how credible the site below is, but they claim the F-16 averages 15 hours of inspections ad maintenance for every hour of flight time. Also that military jets are generally only mission-ready about 50%-75% of the time, which means they spend an awful lot of their useful lives in the inspection and maintenance queues:

Yeah, I was being a bit cheeky - I wouldn't step on any jet plane that hasn't had access to official spare parts for a few years.

I just found it amusing F-14s were bought in the mid-70s, which I guess is around the time many would say the quality of American cars also began dropping.

I would think that any decent military would stockpile any spare parts they would need to 2 years.

I understand if the supply stops they will eventually run out, but this is basic assurances that I'd think any military worth its salt would have in place when buying weapons.
