Most of the time it seems like it’s not a bomb, but triggering some kind of uncontrolled meltdown of a reactor that’s powering the vessel, or maybe blowing up the fuel.

[-] ApathyTree@lemmy.dbzer0.com 12 points 1 year ago

In some cases sure, but even then, like.. why is that so easy to do? And why are there countdowns? And why can it be intentionally triggered? That’s the real weird one. None of those things are even remotely realistic. There should be layers upon layers of safeguards to prevent the super expensive ship that took years to build from blowing up.

I mean we already have auto-shutdown processes for all sorts of explody and dangerous energy sources on earth; we even have auto-shutdown processes to prevent damage to the generator/facility. I’d assume those used to power ships would be among the safest, especially if we’ve made it to real manned exploration technology.

Warships absolutely have a "self destruct button" it's called scuttling. Done to deny the enemy the capture of the ships, or to lodge a wreck in an important location, so it blocks passage. Usually a "self destruct" is ships scuttling, but for space - you can't really do anything to a spaceship to "disable" it and prevent it from ever being used, unless you blow it to bits. Also, explosions are cool.

Same thing for abandonned tanks - burning those is often done - especially if you just lost a track, and the tank is fully operational but cannot move. If you have no chance of retrieving the vehicle, it's better to burn it than to deny the enemy the knowledge about its system, weakpoints, comms etc.

Except for

  • slowing down and hitting the closest sun/planet(even has a "countdown" as it takes a while)
  • hitting the nearest asteroid
  • Attaching or enabling anything that causes cascading vibrations (cause almost any source of wobble can cause the ship to break)
  • ....hitting full burn in any direction, making anyone follow it burn a lot of fuel just to slow it down (would still be recoverable though)
  • probably a few more

Yeah, so in summation - blow it up.

Most of your suggestions require working engines. Shaking the ship apart might make the ship itself unusable but doesn't do anything about on board equipment or intel. A "scuttling" equivalent needs to work when the ship is mostly, or even completely, non-functional, and needs to either destroy everything aboard or make it not worth the effort of recovery.

[-] InnerScientist@lemmy.world 1 points 1 year ago

If you have a second ship then you could use its thrusters.

I also doubt that any explosion short of nuclear is going to destroy most equipment and intel considering the ship is in space and has large parts vented to space (due to combat damage or design). Maybe if you line or fill all the things you want to destroy with some explosives but I wouldn't want to be on such a ship. More likely you'd manually lay down explosives from the ammunition if scuttling is required and then detonate it but not have it already there at the push of a button(assuming you're not using a nuke for every ship).

short of nuclear

In Star Trek at least, where this trope is probably the most firmly established, the self destruct involves antimatter annihilation, which is arguably in excess of nuclear.

[-] InnerScientist@lemmy.world 0 points 1 year ago

...not really the point, the point is that either you have a nuke (or better) or an explosion isn't going to be sufficient to destroy Intel and machinery.

Unless you can justify having a built in nuke/antimatter bomb in the ship then it's not something a real world ship would have(excluding things like special military ships maybe).

Even if you have an antimatter reactor then it would still have to be a procedure on the order of "we're welding the safety's shut and overriding everything we can give us a few hours to rig the ship to blow" not "whoops pushed the self destruct button"

Point being, a colony ship or some science exploration vessel doesn't have a built in antimatter bomb at the push of a button.

[-] vithigar@lemmy.ca 2 points 1 year ago

I'm not sure where I argued to the contrary. The ships in Trek with self-destruct capabilities are all military (or pseudo-military) vessels that are explained as literally having a procedure such as you describe.

In the preferred configuration, the starship undergoes rapid vaporization from thermal and mechanical shock caused by a deliberate release of warp engine reactants. Remote computer system decryption algorithms generate one final set of cascade failure commands, and all engine safety interlocks are compromised. Matter from the primary deuterium tankage and the total supply of antimatter from the storage pods on Deck 42 are expelled simultaneously, producing an energy release on the order of 10^15 megajoules.

If the command links to the engine systems are severed, the secondary destruct system is automatically selected. Ordnance packages are located at key locations around the vehicle, including the antimatter storage pods. These are detonated in concert with intentional overloads of all fusion reaction chambers. The release yield of the secondary system is calculated to be 10^9 megajoules. The secondary destruct system becomes the primary system for the Saucer Module in Separated Flight Mode.

Comic Strips is a community for those who love comic stories.

Rules
  1. 😇 Be Nice!

    • Treat others with respect and dignity. Friendly banter is okay, as long as it is mutual; keyword: friendly.
  2. 🏘️ Community Standards

    • Comics should be a full story, from start to finish, in one post.
    • Posts should be safe and enjoyable by the majority of community members, both here on lemmy.world and other instances.
    • Any comic that would qualify as raunchy, lewd, or otherwise draw unwanted attention by nosy coworkers, spouses, or family members should be tagged as NSFW.
    • Moderators have final say on what and what does not qualify as appropriate. Use common sense, and if need be, err on the side of caution.
  3. 🧬 Keep it Real

    • Comics should be made and posted by real human beans, not by automated means like bots or AI. This is not the community for that sort of thing.
  4. 📽️ Credit Where Credit is Due

    • Comics should include the original attribution to the artist(s) involved, and be unmodified. Bonus points if you include a link back to their website. When in doubt, use a reverse image search to try to find the original version. Repeat offenders will have their posts removed, be temporarily banned from posting, or if all else fails, be permanently banned from posting.
    • Attributions include, but are not limited to, watermarks, links, or other text or imagery that artists add to their comics to use for identification purposes. If you find a comic without any such markings, it would be a good idea to see if you can find an original version. If one cannot be found, say so and ask the community for help!
  5. 📋 Post Formatting

    • Post an image, gallery, or link to a specific comic hosted on another site; e.g., the author's website.
    • Meta posts about the community should be tagged with [Meta] either at the beginning or the end of the post title.
    • When linking to a comic hosted on another site, ensure the link is to the comic itself and not just to the website; e.g.,
      ✅ Correct: https://xkcd.com/386/
      ❌ Incorrect: https://xkcd.com/
  6. 📬 Post Frequency/SPAM

    • Each user (regardless of instance) may post up to five (5 🖐) comics a day. This can be any combination of personal comics you have written yourself, or other author's comics. Any comics exceeding five (5 🖐) will be removed.
  7. 🏴‍☠️ Internationalization (i18n)

    • Non-English posts are welcome. Please tag the post title with the original language, and include an English translation in the body of the post; e.g.,
      Sí, por favor [Spanish/Español]
  8. 🍿 Moderation

    • We are human, just like most everybody else on Lemmy. If you feel a moderation decision was made in error, you are welcome to reach out to anybody on the moderation team for clarification. Keep in mind that moderation decisions may be final.
    • When reporting posts and/or comments, quote which rule is being broken, and why you feel it broke the rules.
Banned Artists

The following artists are banned from the community.

  1. Jago
  2. Stonetoss

It should be noted that when you make reports, it is your responsibility to provide rational reasoning why something should be removed. Saying it simply breaks community rules is not always good enough.

Web Accessibility

Note: This is not a rule, but a helpful suggestion.

When posting images, you should strive to add alt-text for screen readers to use to describe the image you're posting:

Another helpful thing to do is to provide a transcription of the text in your images, as well as brief descriptions of what's going on. (example)
