Feasibility study: The Mammoth Landbattleship

Franberry

Mammoth
Landbattleship



Length: 55 m
Width: 15 m
Height:10 m
Weight: (I have no clue; around 2500 tonnes??)
Suspension: helical spring
Maximum Speed (road): 50 km/h
Range: 500 km (800km with fuel tanks)
Weaponry:

2 x 300mm smoothbore cannon + 50 rounds each
1 x SAM turret (10 missiles in the turret, more inside)
2 x 120mm mortar turrets (4 mortars in each turret)
10 x 20mm Close-in weapons system turrets (There are 2 x 20mm CIWS guns in each turret, arranged to give coverage all around the tank)
6 x 20mm Coaxial Machineguns

Armour: Classified laminated metals/composite + classified modular
(1500mm main turret; 1400mm glacis; 1200mm lower frontal; 1000mm side; 800mm rear)
Propulsion/Engine: [/B]Small fission reactor
Crew: 14 (Commander, 1 Communicator, 2 Engineers, 7 Gunners, 3 Driver)



Is this feasible at all? It would be PMT (or MT, if it is at all possible)
I know it would be ridicoulously expensive, and difficult to transport, but still

Too light, especially if you're going to be using a nuclear reactor.

Kraven uses an Imperator thats 400 tons, its probably currently the heaviest and most armoured and armed tank in PMT nation states, although Im not sure, its designed to Intimidate, lay waste to enemy Defenses and support Troop formations, as well as acting as a Mobile Command Centre.

it is feasable in PMT, but if it gets too big and too heavy, then the terrain will work against you, for example I can't use the Imperator on boggy ground, or in forests, (although these pose less of a problem)

2500 Tones is a little excessive as well :)

Not even close. :) The Morrigan weighs 3,500 tons; the Mk. II of the tank [second variant] will weight ~4,000 tons. The future Extadán will weight probably ~700 tons, but I actually have to get off my ass and write that up. Eurusea has some pretty heavy armor as well in the thousands. My Anat weighs ~3,000 tons, but that's a self-propelled artillery piece with more than one logistical problem.

Massive tanks like this are generally just glorified missile bait, much like SDs. Then again, like SDs, they should usually be uparmoured to deal with this (tacking on ATGMs, SAMs, and so on). Not something I'd design, but your decision really.

Also Mac, wasn't the Morrigan Mk.I the tank with the 381mm main gun?

-1mm. I use these more for the storyline as opposed to actual need and use.

If it was amphibious and could roll along the bottom of the ocean onto land I would like one of these things. I am interested in a seabed tank that could roll onto the land. I know sounds kind of ridiculous but I have underwater cities and there are underwater guns now. Supercavitating cannons. I could have artillery around my underwater cities.

YOu couldn't go across the ocean. End of story. Far too deep, and trenches, and oxygen and all... *shudders*

It is anphibious, it can tranvel across rivers, but not oceans.

And it cannot fight underwater, seeing as how every port must be closed. It would take some time to waterprooft it. Only about 2 hrs with the apropriate support crew

A) (OOC) Welcome to NS. Please read the stickies and enjoy yourself. :)

B) (and this is IC) We also have something classified as a superweapon. It's called a very large thermonuclear stockpile. And I have enough to turn most nations in NS into the largest plate-glass window on Earth. Many nations have even larger stockpiles than I do since I am a only a medium, possibly small-sized nation. Believe me, it would be in your best interest to just walk away right now.

@Franberry
It's looking good, so far. I don't know much on NS designing, but it looks like a formidable force.

A picture would be cool to see. May give every a general idea of what a Landbattleship is suppose to be.

Though the concept seemed able so long as you PMT. Its like a larger verison of the LWSV 'Gladitor'. Though the Gladitor is like an artillery piece attached to a small walking machine with three MG42s. Kinda slow, but I assume this Landfortress is also very slow?

well its got a fission reactor, but I estimate the speeds at around 50km/hr to 40km/hr

also, if my skill at Paint was any indication of my skill at life, I would've died a thousand deaths already.
So as much as I want to make an image, I cant.

Can't you make do on diesel? Nuclear is a bit dangerous and it would be hilarious to see smalelr nations buy these things and have kilometre upon kilometre of a supply convoy ferrying fuel. Since you don't plan on really using it.
Commonalitarianism
19-04-2006, 03:20
Why not use it, you wouldn't even have to use guns in a city, you could simply knock over skyscrapers like godzilla, and treat it like an armored bulldozer, just run over everything in its path. Add an armored bulldozer blade to the front and it would be unstoppable. It would be an interesting way to deal with house to house fighting. Surround it with soldiers and smaller tanks and level the entire neighborhood.
The Beltway
19-04-2006, 03:23
Except for the fact that skyscrapers are a bit more stable than you think, that this thing won't fit on roads in cities, and that it's liable to being ambushed at extremely close range in a city (an IED on the underside of the hull could do some damage, as could one detonating on the top of the hull).
Khurgan
19-04-2006, 03:50
That and I'm rather sure this behemoth wouldn't fit down an awful lot of streets...

Well, that and quick and painful death from dozens of RPGs from above. Much like any tank not specifically designed for urban combat.

Electric reactive armor basically removes any real threat from RPGs.

edit: Now that I look at this thing, it's going to be in real trouble if tanks attack it from the sides. The single 300mm turret is going to take a little while to turn-- perhaps add a couple of smaller AT guns?
The Macabees
19-04-2006, 16:24
ELeRA will not vaporise the HEAT jet... it will distort it and attempt to break it up, but it will not outright vaporise it. It's the same concept as electromagnetic armor and eletrothermal armor.

This thing is kind of pointless. A handful of smaller tanks are mre maneuverable and could run rings around this beghemoth. Aside from that your motive device (treads or wheels) are a terrific weakness. The sheer size of motive device necessary to move this thing would make them especially vulneable and prime targets, especially for anti-tank mines and gunners. Aside from that, anything this big is a great target for conventional artillery.

There is a reason nations don't build tanks this big in RL. ;)
The Macabees
19-04-2006, 17:16

Indeed, because they don't have the money to throw around. The Germans had planned for the P-1000 super heavy battle tank during the Second World War - the war gone awry sorta put that in the trashcan.


A handful of smaller tanks are mre maneuverable and could run rings around this beghemoth.


The question is can they knock it out? Given armor, that would be a no.

Aside from that your motive device (treads or wheels) are a terrific weakness.

Huge and thick skirts?

The sheer size of motive device necessary to move this thing would make them especially vulneable and prime targets


Thus the huge engines.

especially for anti-tank mines and gunners.

Again, you assume that the mines or missiles will penetrate. Things will have to be bigger to penetrate this. Personally, I would use a bunker buster - in fact, after I released the Morrigan Mk. I I also released a special extended range bunker buster to knock these things out.

Aside from that, anything this big is a great target for conventional artillery.

This things are so well escorted that the artillery would most likely already be under fire suppression from friendly artillery.

But in all seriousness, these things should be used for storyline, not as a weapon that will kick ass. That's why I make them, and I'm sure that's why Eurusea makes them.

Armored track skirts do exist, and can be much heavier on something like this. Well, here's a good thread on a discussion on superheavy tanks: http://s13.invisionfree.com/The_NS_Draftroom/index.php?showtopic=789&st=0

19-04-2006, 17:27
So just how mush armor is on these things? Because having just seen this:

The penetration characteristics of tank gun APFSDS darts was so great that enemy tanks could be engaged behind sand berms, the sub-projectile penetrating between ten to thirty meters or sand and still achieving a hard kill. It has been reported that a single M829 round pentrated and destroyed two Iraqi T-72. Apparently they happened to be in line, the 'silver bullet' simply punching through the first tank to hit the second

somehow I doubt its going to be enough. (That's 20-30 meters of sand before killing a tank. From: http://www.army-technology.com/contractors/ammunition/apfsds.htm
The Macabees
19-04-2006, 17:38
At ~2000m range the American APFSDS can penetrate ~600-700mm of armor on average. The common NationStates main battle tank has ~2000mm of armor on the either the turret or the upper glacis - the Morrigan Mk. I has 17,000mm of armor on the turret, although she is going to get revised post battle of Mosnoi Bor and her armor stripped and replaced with just thicker ceramic armors [she uses the billion dollar expense buckytube armor currently - a big waste of money]. The common NationStates APFSDS can penetrate ~1,600mm to 2,000mm of rolled homogenous armor equivalent on average, although it would really depend on the design of the APFSDS - but most people use the 120mm ETC which would offer ~18MJ at the muzzle. That should offer some perspective.
Franberry
19-04-2006, 22:11
Thats Macabees for backing me up, some people think that I shoudl list everything, so from now on I will give more detail.

Also, do you people think that I'm gonna send that thing into battle by itself???
It would have a lot of cover, a tank batallion and a whole bunch of infantry for cover.


Im revising the stats

Here are the revised stats


Length: 55 m

Weaponry:

2 x 300mm smoothbore cannon + 50 rounds each (One massive turret)
1 x 120mm smoothbore cannon (facing fowards)
4 x 120mm smoothbore cannon (these are placed in small turrets on the sides of the tank)
1 x SAM turret (10 missiles in the turret, more inside)
2 x 120mm mortar turrets (4 mortars in each turret)
10 x 20mm Close-in weapons system turrets (There are 2 x 20mm CIWS guns in each turret, arranged to give coverage all around the tank)
6 x 20mm Coaxial Machineguns
2 x Flamethrower turrets (for bunker clearing)

Can be waterproofed (takes a couple hours with the full crew)
Armoured skirts over the tracks (2000mm, came as the armour on the rest of the tank)



(small SAM launchers maybe? It would have mobile SAM units covering it, but since it already has everythign else, should I add it for the hell of it?)
