CCP's central committee and planning are estimating to achieve fusion power for the centenary of the People's Republic; a railgun can be something viable then, no?

You still need to get that power into the railgun, quickly, on a platform that is actually useful for something. Conceptually railguns and coilguns are not hard to make. High schoolers do it. It's making it actually useful that is the problem.

No, there are way more problems involved including the enormity of the capacitor banks and the rails getting eaten away after like 10 shots.

My first job out of college was at this little mom and pop xray machine and supply business. The owner was an older boomer that was an absolute dumbfuck who brought me on to handle sales because he wanted to semi-retire. When we first were going over the customer list there was one customer he said " was a ballistics testing company that used special high speed x-ray film for their testing" and basically described it as like they were just shooting normal guns and taking high speed x-rays in flight which sounded cool but wasn't that neat. Months later I was actually out there for the first time in this nondescript building and I asked the guy what exactly they did and he was like "we're doing railgun research for the Navy and Army" and he saw my eyes light up and asked me if I wanted to see it. I of course enthusiastically said yes and the owner was with me and really couldn't understand what the big deal was. It was huge and the power requirements were ridiculous. There were these giant two story capacitors in banks going almost the length of a football field. The gun was really cool and he showed me all these different types of armor with giant holes in them. They were different type of ship and tank armor and a few of them he couldn't tell me what they were because they were classified. It's crazy to see super thick slabs of armor with giant gently caress off holes in them. They were getting ready to shoot it but wouldn't let us stay for that so we went and had lunch down the street and you could feel the thump when they fired it. It's too bad the Navy couldn't really make it work because that thing was loving rad as hell and would gently caress things up from way over the horizon before they even knew it had been fired.

The Chinese already built a rail gun and put it on a test ship. Their project is still ongoing which is not the case for the US rail gun.

how about a coil gun with the projectiles being cylindrical bullet-type things? grease up the tube real good and you at least have deal with the wear issue a bit. they could have deployable fins and rockets too, why not as far as capacitors i guess you just need a fuckton of tantalum?

The main thing is that it turns out chemical storage of energy is actually really efficient per unit of volume and weight. That said I always thought it was kind of interesting how nearly every depiction of a railgun assumes the projectile would be an inert piece of metal. There's surely not much reason not to put a warhead on it. Depending on the length of the railgun you might even be able to accelerate the projectile more smoothly and gently than with an explosion.

The thing is the hypothetical railgun's main advantage is the absurd acceleration - meaning anything it tries to launch must also be able to withstand that acceleration. You could if course make it slower but at that point why use a rail gun in the first place

Supposedly the air force had a research concentric rail gun that fired plasma that had some absurd capabilities but it was the size of a warehouse and nobody knows if the research ever continued https://en.wikipedia.org/wiki/MARAUDER

It's long been rumoured that many of the "UFOs" over area 51 were actually a device that produced plasma in the atmosphere for either a weapon or to gently caress with enemy radars etc.

The concept of plasma stealth has been around for a while. It hasn't ever been publicly demonstrated to work. Wouldn't be surprised if there have been experimental aircraft that have tried it.

my fav gauss gun is the necron one from 40k that has zero resemblance to what a gauss gun is and was clearly named by some 80s writer who thought gauss guns were just a fictional sci-fi term and not a real thing I think they later retconned it to being named after a guy named gauss that discovered them in universe

gauss was one of those guys that's so smart reading his biography makes him seem like an alien or a time traveler or something. like newton, maybe einstein. so it's funny the thing he's most associated with is videogame guns when he's central to astronomy, physics, mathematics, magnetism... and more!
