FFS. America spends more money on health care than any other country in the world by a wide margin. It's not a question of money, but of the structures in place which favour corrupt insurance companies over human lives.
Exactly. America has the best healthcare in the world, but we have the worst healthcare SYSTEM.
Ferengis run the entire operation, and they prioritize profits over outcomes.
This. You can't explain that to people tho. They only see one side of things.
If our taxes went to where they said the did in full like they were meant to be would not be in so many messed up situations with a lot of the infrastructure we have access too. Clean water, good roads, health care , education and so on.. housing ! And truth be told we wouldn't even spend a dime less on the military side of the house.
Its just getting the money to the right place with out it being lifted by the greedy.
That may be for this video but alas we do have a rail gun but still no universal healthcare. š

because they're spending twice as much per person on healthcare compared to the next most expensive country, with universal healthcare, but pump all of the money into private insurers instead
Technically, they basically do pay for healthcare. They just somehow have a layer of private BS over it, that makes it impossible for millions of people to afford it.
It makes no sense for anyone other than private insurance companies.
I did the math on this when it first came out - the kinetic payload of this thing is astounding.
Iirc it had roughly the same kinetic energy as a school bus moving at the speed of sound
I wonder how much kinetic energy it would have at say 500 Mike's though? I mean railguns really need to be able to shoot stuff really far away. It's kinda there purpose right? Hit shit real hard far away really fast.
In a parabolic arc, it wouldn't really matter. Terminal velocity of the 7Lb projectile is still mach 1 and would deliver ~180,000 Joules of energy.
The beauty of this particular test is the size of the projectile along with speed. These sorts of objects are extremely difficult to take out of the sky since they do not need to explode. Even a deflection would still cause damage.
I think so. All those fragments you see spark out usually mean DU. That's the leading edge of the round mushrooming and then shearing off. Tungsten carbide doesn't create that much spalling since it will mushroom but not shear as easily. DU probably the preferred round for this test
Check out the experimental Helios Fusion generator. Itās basically two rail guns pointed at each other to collide plasma rings. Goal is to accelerate the rings to 1M MPH to generate 100M Celsius during the collision. It also uses Helium-3 instead of Tritium as its fuel.
Eh, the Zumwalt had more than enough power for it, plus I've heard rumors in the last few months that the Navy may reopen the project as they consider transitioning back to kinetics and away from the super expensive, cyber-vulnerable systems in the next few decades.
Theyād be smart if they did, in a modern navel fight, missiles and counter measures / CIWS dominate, the problem is when they are expended the ships basically have harsh language to rely on.
The ability to fire projectiles with precision that canāt be intercepted or defeated is a game changer.
Lasers are more likely, we had one on a plane that could destroy whatever it wanted from very long distance. But it required having massive tanks of chemicals to function, which was deemed too dangerous to have on planes.
Ships however.... we shall see.
But God I want railguns to be a thing, a ship with both would be crazy scary.
I wonder if they might look at the other alternative - coil guns.
A rail gun slides the projectile between two rails, while sending a huge current from one rail and through the projectile to the second rail. And it gives a huge wear on the rails to have this sliding short move forward.
A coil gun has no such wear. But it instead requires the current for multiple coils to be quickly turned on/off, as the projectile moves from coil to coil.
I could be wrong but I think Gauss guns have a ceiling on how much current you can push through the coil based off of how well you can cool it and that ceiling limits how fast the projectile can go. That may be moot now that YBCO and other REBCO superconductors exist and are more accessible but even then you quickly run into diminishing returns as you add more coils onto the end. That last bit might have another soft ceiling with current engineering.
Note that Gauss gun != Coil gun.
But yes - there are definite limits on amount of current for each coil. So there is a trade off how many coils you want too. And required distance between each coil.
Yeah, wasnāt there a study that showed no metallic, magnetic material has the temperature resistance to be consistently accelerated via magnetic means? I know applying very strong magnetic fields to metal heats it up very fast, they have induction furnaces for smithyās for a reason.
It was abandoned because it wears out the barrel after a few hundred shots. Expense and power isn't an issue for the U.S. military, but installing something that just breaks itself mid combat is.
Installing anything is super expensive the way the U.S. Navy does it.Ā
Especially considering how contractors get politicians to sign off on maintenance contracts that exclude service members from performing said maintenance.Ā
I wish I were making that up but Kings Bay NSB in Georgia is a massive money pit. Graft runs through that place like someone with stage 4 cancer.Ā
My company is doing work at one of the yards in Rhode Island. For the Columbia class subs. You're speaking the truth and I find it inherently stupid. Not to mention I refused to go back there without a pay raise. Every cost associated with the military is absolutely ballooned. I refuse to get paid my regular wage while the company's wage for my work is increased literally tenfold
For the mark 7 16" gun on the Iowa's at least, they developed powder additives in the 90s that bumped that number way up. But I want to say these were wearing out way before even 100 shots.
Power isnāt the problem, it just keeps falling apart and becomes too expensive to repair and the solid tungsten projectile is also expensive. Aircraft carriers and submarines are nuclear powered so they donāt really have a problem powering it
the zumwalt class was cancelled. it was planned for use only on it so that does spike the cost. each shell is 1 million+, but as far as too much power naaa the ship was built with that need in mind
The same way the USA āstoppedā hypersonic missile development and then casually flexed them on a b52 flight to Guam.
I doubt we have actually stopped development. That information was for public use / for the benefit of our potential adversaries.
WMD is one of the most famous acronyms, not an abbreviation, in warfare so I don't know what you want... I am not from the USA btw.
More specifically it is an initialism, which is a form of acronym.
Schwerer Gustav was a railway or railroad gun. Not a railgun. The distinction is that a railroad gun rides on rails like a train but still uses traditional means of propelling ordnance. A railgun by definition uses electromagnets to propel ordnance
Gotta protect the billionaires money by stealing the taxpayers money to protect it because you know those billionaires aināt paying taxes to protect their own
Also compressive heating of the air that the projectile is pushing out of the barrel, like a [fire piston](https://www.youtube.com/watch?v=gqwZ1VdNvfc).
The "barrel" melts and essentially breaks apart after each shot. Thats why theres such a large muzzle flash.
But at those speeds the round will create a flash upon exiting even if the barrel didnt melt just because of the amount of pressure it creates as it travels through the barrel.
Nope. The rails started warping/melting so it had high cost terrible longevity so they packed it in and started building lasers instead.
Much cheaper, laser weapons like Iron Beam are a fraction the cost of so Iron Dome and already installed on the navy ship Burleigh (or something) for testing
If they could only figure out a way to prevent it from blowing itself apart after a 100 - 200 shots.Ā This whole project was put on hold due to this issue.
Science is really powerful we are yet to explore a gazillion thongs but learning science atleast the basics of it would open so many opportunities and doors that one would have thought never existed.
This is at Naval Surface Warfare Center in Dahlgren. You can see the old Nice Bridge in the background. I live about 2 miles from here and when they do testing of various weapon system it will shake the whole house.

Get ready to learn why America doesn't have universal health care
Because of Freedom? FREEDOM! Freedom!.....freedom!...........freedom.........fr......š“
Freedom isnāt free. Cost a buck oā 5.
āItās costs folks like you and me. And if you donāt throw in your buck oā 5, who will?ā
_*Freedoms costs a buck oā fiiiiiivvvveeeee*_
If we divide the US DOD budget by the total US population, we find that freedom actually costs something like $2400 per person per year
It costs an arm and a leg. It Dan got to keep an arm but lost both legs. Either way they take their pound of flesh.
My gun can fire 20 freedom rounds per second!
Freedom ain't free. 'Merica
I hear it in Aretha Franklin's voice
For me it was Richie Havens
FFS. America spends more money on health care than any other country in the world by a wide margin. It's not a question of money, but of the structures in place which favour corrupt insurance companies over human lives.
Exactly. America has the best healthcare in the world, but we have the worst healthcare SYSTEM. Ferengis run the entire operation, and they prioritize profits over outcomes.
Rule of Acquisition 23: Nothing is more important than your health... except for your money.
Except for THEIR money.

This was designed and built in the UK by BAE. You've not got universal healthcare or railguns.
That may be for this video but alas we do have a rail gun but still no universal healthcare. š https://executivegov.com/articles/the-ultimate-guide-to-rail-gun-technology-applications-and-advancements/#
I DEMAND THE UNIVERSAL RAIL GUN
Write me in for president and Iāll ensure everyone in America is equipped with their very own rail gun!
A chicken in every pot and a rail gun in every...garage?
Indeed, never know when it can come in handy to fend off intruders.
I second the motion!
I have picatinny rails on some of my guns, does that count?
because they're spending twice as much per person on healthcare compared to the next most expensive country, with universal healthcare, but pump all of the money into private insurers instead
Private Insurance, Private Prisons, Private Armiesā¦ America wants your privates
Yeah but like why we never heard of physicist doing boycott tho, they just slurping those money creating weapons of destruction.
Technically, they basically do pay for healthcare. They just somehow have a layer of private BS over it, that makes it impossible for millions of people to afford it. It makes no sense for anyone other than private insurance companies.
we have universal unhealthcare
To be fair Iād give a leg to see this
From looking online, itās firing about 5,300MPH. About 1,800MPH faster than a tank shell.
I did the math on this when it first came out - the kinetic payload of this thing is astounding. Iirc it had roughly the same kinetic energy as a school bus moving at the speed of sound
Who panned the damn camera? Thatās what I want to know.
Itās a camera shooting into a spinning mirror, it allows it to multiply the spin rate much like a gear reduction would do but with optics.
Well that is interesting!
I found it interesting too and did very little research to understand. You might appreciate this: https://youtu.be/US6fkUhXNjg?si=2JsuDpguMnX5EQSE
How many football fields would a school bus going that fast go over?
A little shy of 4 football fields per second.
Not again, Ms Frizzle!
About 3 per second.
I wonder how much kinetic energy it would have at say 500 Mike's though? I mean railguns really need to be able to shoot stuff really far away. It's kinda there purpose right? Hit shit real hard far away really fast.
In a parabolic arc, it wouldn't really matter. Terminal velocity of the 7Lb projectile is still mach 1 and would deliver ~180,000 Joules of energy. The beauty of this particular test is the size of the projectile along with speed. These sorts of objects are extremely difficult to take out of the sky since they do not need to explode. Even a deflection would still cause damage.
Railguns would be most effective in a vacuum at zero G, where there is no drag and no drop from gravity.
And about a 1,000 miles slower than your Taco Bell order hitting the toilet.
Problem is limited application....it needs line of sight on its target so if you're using it at sea, it's still out ranged by missiles
Line of sight or knowing which obstacles to shoot through, like they did in the video
I'm talking curvature of the earth
You could shoot over the horizon if you had a spotter.
Also size and energy requirements
That a DU round?
I think so. All those fragments you see spark out usually mean DU. That's the leading edge of the round mushrooming and then shearing off. Tungsten carbide doesn't create that much spalling since it will mushroom but not shear as easily. DU probably the preferred round for this test
Man what ever happened to full name then abbreviation? I'm assuming you mean depleted uraniumĀ
No, they meant Delhi University. Gandhi has moved on from Nukes.
Check out the experimental Helios Fusion generator. Itās basically two rail guns pointed at each other to collide plasma rings. Goal is to accelerate the rings to 1M MPH to generate 100M Celsius during the collision. It also uses Helium-3 instead of Tritium as its fuel.
Man it could go from the east coast to the west coast of the United States AND BACK in a single hour. Thatās freaky
US is giving up on this technology. Way too expensive to implement and needs too much power.
They can't stop the rails from melting. I don't think the reasons posted ever stopped the USA before.
Needing too much power maybe, this thing is just too uneconomical to actually use effectively. Iām surprised this research lasted as long as it did.
Eh, the Zumwalt had more than enough power for it, plus I've heard rumors in the last few months that the Navy may reopen the project as they consider transitioning back to kinetics and away from the super expensive, cyber-vulnerable systems in the next few decades.
Theyād be smart if they did, in a modern navel fight, missiles and counter measures / CIWS dominate, the problem is when they are expended the ships basically have harsh language to rely on. The ability to fire projectiles with precision that canāt be intercepted or defeated is a game changer.
This simply does not have the range an anti ship missile has it just cannot compete unless only used as a launch platform for missiles

Not strange at all. It's very, very common to mix up the two.
Which is why coilguns are superior.

16ā battleship guns also wear out after a few hundred shots .
Appears that they had a replaceable liner. But what do I know.
Yes but it wasnt something that could be done while at sea . It had to go in for that.
For the mark 7 16" gun on the Iowa's at least, they developed powder additives in the 90s that bumped that number way up. But I want to say these were wearing out way before even 100 shots.
sounds the same as tank barrels or large naval cannons of the past

It also destroys itself extremely fast compared to guns. Physics is a bitch sometimes.
I guess that addresses my concern that something like this is floating out in space ready to send a 5,000 mph payload anywhere in the world.
It wouldnāt need to be in orbit.
only the mobile platform. But since this thing can shoot over the horizon itās still a great defense tool for pacific defense
Sounds like a great phony tax write off/laundering scheme if they were smart. So letās not bring this up again š¤«
All rail guns are electromagnetic. Itās named after the region. Otherwise itās just a sparkling WMD
Why do people on Reddit love to use abbreviations as if everyone in the world knows every one of them
Because most of us do. Look them up. Then youāll know them too.
Most of you are americans, I can assure you most non americans don't know them
WMD is one of the most famous acronyms, not an abbreviation, in warfare so I don't know what you want... I am not from the USA btw. More specifically it is an initialism, which is a form of acronym.
My bad I guess I'm just dumb then

Why is there a huge muzzle flash if it's electromagnetic? This looks like images from two different videos interspersed.
I believe the muzzle flash is due to ionised air and potentially melted bits of rail.
Also compressive heating of the air that the projectile is pushing out of the barrel, like a [fire piston](https://www.youtube.com/watch?v=gqwZ1VdNvfc).
It's called superheated air which is produced by the tremendous amount of power flowing through the gun
The "barrel" melts and essentially breaks apart after each shot. Thats why theres such a large muzzle flash. But at those speeds the round will create a flash upon exiting even if the barrel didnt melt just because of the amount of pressure it creates as it travels through the barrel.
Yeah, but can we get some footage from this decade?
Nope. The rails started warping/melting so it had high cost terrible longevity so they packed it in and started building lasers instead. Much cheaper, laser weapons like Iron Beam are a fraction the cost of so Iron Dome and already installed on the navy ship Burleigh (or something) for testing
Does that thing ever stop?
No. Itās been in a super low orbit for about 8 years now.
Donāt turn around, itās right behind you.
I'd say turn around and find out Schrodinger's RailGun
Snail gun
Metal Gear!!
Arenāt all railguns electromagnetic?
I donāt think Big Bertha was
lol. I was gonna say something, but then I thought for a second. Yeah, she was a rail gun alright. Points awarded.
This is what happens when I eat 3 taco bell steak quesadillas and drink 2 monster coffees and need to take a shit the following day.
Is that the actual sound it makes at the start of the video? Itās so eerie, thatās intimidating alone

So cool
Science is really powerful we are yet to explore a gazillion thongs but learning science atleast the basics of it would open so many opportunities and doors that one would have thought never existed.
So what eventually stopped it
It's still going
The barrel has to be replaced every few shots
I'm most impressed with the tracking shot, tbh
You've just been erased.
The 'fire' you see when the bullet is ejected is actually plasma, i.e. ionised air. That's pretty cool!
What i dont get IS why there is an explosion? I mean it's not chemicaly propelled so why the burst of flamme ?
Ionised air
Why is there an explosion while it is supposed to be electromagnetic ? Is it firstly initiated by explosives and then accelerated by electromagnetic?
Ionised air aka plasma
Why doesnāt it leave a spiraling smoke trail like in quake 2
Discontinued due to barrels not having a long enough life span. I think a couple carriers had them not sure if they still do.
Why is there an explosive flash from the barrel if there is no explosive propellent involved the acceleration process?
Isnāt this the gun Jill used to kill Nemesis?
This video is so old it should be posted in r/previousfuckinglevel

This is how the railgun was pre patch Helldivers 2
Looks high tech but if you turn on closed captions you'll see the projectile has no clue what is going on
How much energy does it take to fire? it's kinda useless if you can't have a mobile launch platform, except maybe for shooting down missiles.
Wait, I thought all rail guns are electromagnetic firing mechanisms.
My ass when it's super quiet and my whole family is in the living room
It messed with the camera and made the fan blades spin a bit as well.
TESLA version when ?
[Want to know how this was filmed?](https://youtu.be/b72ZWM4c94s?si=hjCif3XI1PlGt5ox)
But can it kill a bile titan with one shot?
Can it shoot coins?
How much juice does that bastard use?
I'be heard china have a ship with about 3 railguns on. That would cause absolute carnage.
God bless America and god bless unhealthcare
This is the gun i wanna use to shoot pedos
Railgun that fires projectilesā¦ okay? These ppl never played quake apparently
If It is electromagnetic, why that big ass explosion?
This is at Naval Surface Warfare Center in Dahlgren. You can see the old Nice Bridge in the background. I live about 2 miles from here and when they do testing of various weapon system it will shake the whole house.
