because it apparently didn't go up as high as it was supposed to, the test was ultimately declared unsuccessful.

Poor Chinese. They have yet to learn so much from Elon (hint: declare everything a success. NO. MATTER. WHAT.)

One of my favorite Star Trek quotes of all time: “If the invasion had been considered a defeat Gowron would’ve been assassinated by now. He simply declared victory, and went home.”

A new space race with railguns would be the fucking coolest thing ever

Spinlaunch has been trying to make a catapult-to-orbit out of a miniature hyperloop. Actually not as dumb as I made it sound (but it does have its own issues)

until they use the tech to drop bombs more effectively

Unless your upper half happened to be on the upper path of one of those things. Then it would probably be amazing for like a nanosecond. In the most macabre way I suppose. But just a nanosecond. After that when you fully realize what happened there probably wouldn't be much you left to keep realizing anything past that.

You can launch payloads into orbit with less pollution and for cheaper. You can build habitations with the material and bring humans up the traditional way.

Of course though, the powers that be are going to be more interested in killing each other.

It goes without saying that we should work out any safety issues before that

I wonder how much more energy it took to accomplish that compared to just shooting a rocket. Last I had heard railguns weren't really feasible because of the absurd amount of energy they would require even with perfect efficiency.

[–] UraniumBlazer@lemm.ee 18 points 1 month ago (1 children)

It's not the absurd amount of energy that's the problem. It's the absurd amount of energy that has to be STORED AND RELEASED within a fraction of a second in a controlled fashion.

If you wanna go electric, you would need a stupendous amount of capacitors and a gun that won't get destroyed due to the immense energy release.

If u wanna go chemical (like an actual gun), u r faced with the same problem of the gun exploding.

The only approach that MIGHT work is the Spinlaunch thing, where u essentially store this energy as angular momentum in a THICCC carbon fibre rod. Spinlaunch is still yet to demonstrate anything remarkable, so there's that.

I'm no expert, but I could imagine rail-guns would be a huge advantage on nuclear powered vessels. For one the ammo doesn't explode if hit by enemy fire, and I'm guessing the ammo would be super cheap. In theory you could shoot bars of iron.

[–] EvilBit@lemmy.world 9 points 1 month ago (1 children)

They might also have a much smaller launch signature, meaning harder response to a first-strike launch. But I’m not a physicist or nuclear deterrence expert or anything.

[–] APassenger@lemmy.world 3 points 1 month ago

When it's not an experiment:

  • Do we know where it is?
  • Is it mobile?
[–] NotMyOldRedditName@lemmy.world 0 points 1 month ago

This is the military we're talking about.

They'll turn a metal ring into a million dollar thing making sure it has 0 flaws on the surface that might cause 1 in a million shots to go off course.

[–] Sabata11792@kbin.social 5 points 1 month ago

If you have the opportunity to involve a giant rail gun in something, you do it.

[–] guacupado@lemmy.world 2 points 1 month ago

They're not feasible because of the erosion of the barrel with our current level of materials science.

[–] psmgx@lemmy.world 11 points 1 month ago

...a weapon to surpass Metal Gear

[–] gari_9812@lemmy.world 5 points 1 month ago

That's horrifying... but TBH it also sounds kinda sick

[–] acockworkorange@mander.xyz 4 points 1 month ago

And when I said that their “electric launch system” for “scientific space exploration” was just a public testbed for a missile launch system, a small army of tankies descended upon me.

[–] tsonfeir@lemm.ee -2 points 1 month ago (1 children)

If it’s so smart, why can’t it launch itself? 🤓

[–] Zorque@kbin.social 6 points 1 month ago (1 children)

Its so smart it gets something else to do all the work for it.

[–] SatansMaggotyCumFart@lemmy.world -5 points 1 month ago

It might be a mistake to allow AI’s control of weapon systems.
