When will the Zumwalt finally get the railgun?

The whole purpose of this ship was to have railguns eventually.
I'm sure that someday the railgun will come.

      I think the railgun got cancelled, but with the leftover juice from the powerplant ant integrated system they could put a shit ton of DEWs on it. make it into a Neo Super-Alaska.

      Zumwalt is getting a hypersonic missile upgrade. Railgun was cancelled.

    I thought it was for some guided extra range conventional gun? (That was cancelled)

      The gun wasn't cancelled, the ammo was. There's a total of 200 rounds for all three ships with no plans to ever purchase more.

        No difference.
        The technology isn't ready so any railgun mounted later will have nothing in common. It still have plenty of limitation, it won't sustain fire, you have to replace the rails after a dozen of shots and its range is still not long enough to keep the ship out of trouble.
        That said, I don't know what they where expecting from it as missile defense go. Sure railgun would be good to precisely snipe one missile but any other gun could do that if precise enough.

        They started building the Zumwalt before knowing if the railgun would work.
        This wouldn't be a problem if the Zumwalt was a modular masterpiece able to swap any weapon, but it's more like overpriced & badly managed US project.
        Better than the LCS I guess.

          It's still a stealth ship, right? Get in to target's personal space, shoot them to shit because @armorisoutdated202X, and get out like a sea-bound F-117.

          Zumwalt's mission profile feels like it has more in common with a U-boat than any destroyer or cruiser.

            As I know about it, the stealth is only about making it hard for cheap as frick radar missiles to lock on or misjudge the range.
            It's impossible to hide a ship from any decent radar.
            (top level anti-ship missiles recognize ships by shape)
            Eventually even submarines won't be able to hide, an AI with consumer sensors will analyze the sound reflecting of a shutdown electric submarine and pinpoint its position to the meter from 1000km away.

          objectively false. making a cannon that would be able to survive the shot requirement the navy wanted was relatively straight forward and with more funding it could be done. the problem is that you'd need to make a bespoke industry just for the metallurgy for this, which while the US has moved primarily to specialty steel production, the cost involved in creating all this just for three ships (for the foreseeable future) that can power and mount such a gun makes it not economically viable.

            >objectively false.
            That was quoted from the article.
            They improved the latter prototypes but I've not heard of value like 100 shots before replacement.
            Also you pretty much agree with what I said about the industrial cost.

            Coilguns are hard limited by physics, they're worse than railguns for anything faster than a few hundred m/s.

            As I looked into the concept it seem coilgun are superior in spec but more complex and harder to miniaturize because you need several stage for each level of acceleration.
            Railgun are just functionally simpler and that's probably what attracted the funding.

              Unlike railguns they need a magnetic material to work, magnetic saturation limits the acceleration far more than rails, already bad enough for anything faster than 1 km/s.
              Current railguns are primitive but even for very low speed they're roughly 10 times less efficient than railguns...

                Magnetic material aren't hard to obtain and it's not called a big problem anywhere I look.
                At worst it will be a metallurgic race against the "perfect rails".

                Magnetic saturation & efficiency is what is solved by multiple stage acceleration, which require perfect switching. That, is the big problem because it take more room and precisions on par with perfect rail.
                If we were lucky it would just mean high-quality components that we would gladly mass produce for other use, but we are never that lucky.

                Well get them at the same time as Fusion reactor, it's 10 years away for sure!

                The problem isn't magnetic material, it's magnetic material that can stand up to the acceleration force and has high hardness and density for penetration. You're going to end up using some exotic cobalt alloy that costs as much or more than tungsten and still doesn't work as well.

                No different problem than the Railgun then, acceleration can be controlled. The problem is that a coilgun would need to do so in multiple stages, very complex and encumbering.

              Several countries are funding railgun programs now. Just because the USN gave up doesn't indicate a nonviable rail life.

    we don't have the tech to create practical pure railguns.
    but we can create a three-stage railgun to compensate for it.

    1st stage - explosive chemical propellant to kickstart and accelerate the projectile down the barrel.
    2nd stage - magnetic rail to accelerate the projectile even further and out the barrel
    3rd stage - rocket motor of the projectile is activated and accelerates the projectile at it's maximum.

        so a spike of velocity for a projectile that happens within 1 second is no good...
        but smoothing that same spike of velocity for a projectile that happens within the span of 5 seconds is better?

      Long range cheap ammo can work.
      The problem IMO is trying tech that have serious material friction/stress.
      Artillery cannons barrels already have problem with stress. Railgun basics involve wearing the rails, if those rails are supertech that ruin a small country to make, it's was not a good idea.

      I wonder how hard it is to make coilgun without barrel/rails friction.

    They already have it but it's not what you think.
    There's a reason that MARAUDER was re-classified. The Zumwalt railgun program and cancellation was just a cover to conceal it being deployed.
