Military Ground Vehicles of Your Nation [NO MECHS] Tranche 7

[The Akasha Colony]

Then about eight meters. Not sure I would recommend that though...

Its a gun, it has no "minimum range".

arming distance and that stuff

Depends what you're shooting. But if it's a contact fuze, then however long the gun barrel is, so long as you're okay with the barrel opening up like a flower.

[Yukonastan]

How long is the gun?

Well, if you're having to use your PzH2000 as a direct-fire AT gun, you've already lost. Other than that, closest range would probably be around 50m, but that would still be really risky.

Not that I would, but in case of emergency, a 155 HEAT shell can expect about 800-900mm RHAe penetration, no? And with the halfautoloader, it can fire pretty fast for a gun that size.

[Purpelia]

I have a random question. Why does everyone feel my YMIR is massively heavy and huge? I mean yes, it is large. But it's basically an autoloaded GLATM launcher like the MBT-70 only without the turret and armor. So it should actually turn out light for its size.

[Imperializt Russia]

In a similar but opposite vein, what's the closest range I could theoretically take, say, a PzH-2000, and use its gun in a direct-fire role against say, an MBT?

It's possible, but this is a suicide run made under the instance that a line has collapsed so heavily that the artillery has not known to run away.
Though Paladin crews apparently train for it.

And that's the whole point. if/when the shit hits the fan and communications break down massively all along the line, the artillery can at least take some of their attackers down with 'em, if not slow down the attack by a bit.

Because if the goal is to launch missiles from range and has no need to stand in direct combat (like the MBT-70) or fire direct-fire munitions (like Shillelagh was designed for), it should look more like a regular ATGM carrier rather than a tank destroyer. Or perhaps an MLRS. There's no reason for that inefficient arrangement if all it has to do is fire a missile.

Actually there is. If you have seen my cross section of it you would see it.

Basically, the reason is that it allows the system to fire and reload whilst remaining completely self contained. A regular ATGM carrier or MLRS needs either a supporting vehicle or people to get outside and reload it between shots. Probably both. And in the projected future battlefield which is continuously contaminated with chemical and radioactive fallout this is too dangerous.

Basically, to see the evolution from an ATGM carrier to a Ymir start off with your standard vehicle.
1. Notice that it's slow and dangerous to reload so add an autoloader.
2. Notice that with the autoloader in place you do not need a large number of "ready" tubes so cut it down to just one.
3. Notice that the autoloader arrangement is large and bulky requiring a huge turret which makes the whole thing unacceptably heavy and large, so cut the turret out and go casemate.

Then if it's only designed to lob those absurd A-HEAT ATGMs, why does it have such a long barrel?

[Yukonastan]

See my factbook. It's in my sig.

I saw. That thing is ridonkulous, look at an S-tank for a better gun placement.

[Saphirasia]

That thing is ridonkulous...

And not in a good way. Artillery already does what this thing is claimed to do, why add a completely different vehicle to do a job that's already covered?

The Ymir never made sense, except as a compensatory device.

It's actually not long at all. Do an experiment and superimpose the shell over the barrel. You'll see that the whole thing, chamber included tops out at just a tad over 2x projectile length. In other words, barely enough for a cold launch.

I would if I was making one of these.


But I am not. I am making one of these but with an autoloader.

[Allanea]

I always thought, tbh, that the Ymir is an elaborate joke by Purpelia.

[Purpelia]

I always thought, tbh, that the Ymir is an elaborate joke by Purpelia.

It is. But being elaborate there is also just enough technical realism inside it to seem reasonable if you tilt your head sufficiently. Which is what I am trying to explain.

The entire concept of course is questionably sane at best. But once you accept that the actual technical details are or at least should be in line with it sufficiently to make it plausible. That's the joke.

There are already autoloaded ATGM carriers.

Well, you need to squint your eyes also.
This is what I mean. This thing can hide hull-down a lot better than yours can. And it still fires GLATGMs.

I would try superimposing it, but there's no breech to use as reference.
Unless the launcher design just vents its gasses into the crew compartment, you do need something to act as a seal over the inside end of the barrel.

Now imagine one of those armed with what is basically a BM-30 rocket. That boom arm just won't work. Especially not if it has to fold up to align with an autoloader.

For direct fire that one would be superior. But as my design is an artillery weapon it needs a degree of elevation. Even if it's rather small.

The cutaway model is a crude rendering. It omits details of the gun and other assemblies. Just assume that the polygonal looking metal pipe is a plausibly looking gun-launcher.

Why? Just use LOSATs, the army planned to stick them onto humvees, you could make a heavier platform if you wanted.

It works like the S-tank does, by adjusting the suspension it elevates up to twenty degrees. The missiles then climb up high if they're smart or travel ballistically if they're unguided rockets.

IIRC the S-tank's suspension only offered +/- 10 degrees elevation/depression. The depression is good but 10 degrees elevation is really shit.

[Purpelia]

Why? Just use LOSATs, the army planned to stick them onto humvees, you could make a heavier platform if you wanted.

The WHY is the key point, and basically the joke. The idea being that since in NS the cold war always goes on tanks like the FST-3 and it's western counterparts (140-155mm guns, impervious to 120mm on the sides etc.) would actually have been built and that the next generation of tanks (Future Barbarian Tank 4) would be even more over the top (170-190mm main gun, impervious to 140mm tank guns etc.) so fielding a regular tank capable of one upping these would be just too expensive and too much of a tradeoff in terms of everything but armor and the gun. And a dedicated TD attached to armor formations could take these out at range and allow the rest of the armor to do their thing and fight the enemies regular armor and infantry and stuff.

If you wanted to have a sales pitch it would go something like this:
In the grim future of a newer ending cold war going hot massive landships roam the toxic, irradiated fields of a plowed up earth. Bearing 19cm canons and enough roof armor to take a javelin to the crew hatch and laugh these vehicles are called MBT's. Enter Ymir.

The point is basically me looking at the newer ending NS arms race and people trying to shove PMT into MT and stuff (you know who you are) always searching for a bigger stick. And to just preempt the arms race by making the ultimate stick.

Want a giant armored fighting robot? Ymir to the face.
Want a landship with 16 inch gun turrets? Ymir to the face.
Giant bucket excavator with T-72 turrets from CYOE? Ymir to the face.
NS supertank? Ymir to the face.

It works like the S-tank does, by adjusting the suspension it elevates up to twenty degrees. The missiles then climb up high if they're smart or travel ballistically if they're unguided rockets.

I would be using that to make up for a lack of proper elevation. But that's not nearly enough.

[Gallia-]

1) Please stop neglecting the letter "v".
2) Guns do not, for whatever flimsy reason you seem to be justifying, need to increase in caliber by 20mm every generation.

+/- 11 degrees, to be exact.

Which isn't bad for an ATGM carrier.
