How effective would a Landkreuzer be?

If the germans produced this monster, would it be a german white elephant like the Yamato class BB was, or the Landkreuzer P1000 could be worth it?
 
Since the only way to get the thing to battle would be to invite the enemy to attack the factory would not actual white elephants be somewhat more useful?

How would they get that bad-boy out of the builder's yard? Every river would need to be forded. How do you cross a river of any depth, let alone even soft ground?

Would there be enough diesel fuel in all of Germany to refuel this thing?

Come on guys - be fair.

Nowhere did the OP say the Landkreuzer had to be made from steel. Could have been cardboard. Could have been plywood. Paper. 2D. It could have been a big giant balloon. A bouncy castle?

not much effective
like the name say Landkreuzer = land cruiser
this is tank version of a cruiser, carry naval guns turret and Flak guns, power by two to eight diesel engine from Submarines
They believed it drive 40 km/h (25 mph) at maximum on flat hard surface.
That was wistful thinking, i beliefe that Landkreuzer would only move with 5 km/h (3 mph) on battle field
and it got only range of 190 km and it's 1000 tons (2,204,622.0 Lbs. ) make it unable to transport by railway
were it drive it destroy bridges, transforming automatically roads, Autobahn into trench for succeeding infantry.

next to that had Landkreuzer a "support Fleet" of Maus tanks, hunter tanks Jagdtiger, etc.

While a huge waste in any case, whether such a vehicle would be entirely useless would depend largely on whether adequate air cover could be provided for it.

Did Germany have that much Rubber? Think of the increased number of Pregnancies that would result? :D
 
Buys the local Germans a few seconds/minutes while the Allies call in an airstrike. Might do a bit of damage those few minutes at far, far less economic of the cost literally anything else could. Probably for defensive use only, since it's so horrifying slow.

But highly effective when anyone would need to recall off the top of their head why the Nazis lost.

Not really,this just determines how quick it will be killed. But if you define "not useless" as "be more than a poorly armored,stationary fortress" than its always useless.i mean,how is this thing ever going to cross a river? it can never enter any form of settlement. the few roads it that can fit it would get destroyed.

The ground pressure would not, I think, be insurmountable - it's got an area of 490 square metres, so it's only about two tonnes per square metre of horizontal area.

If the treads are 1/2 the width of the vehicle (as per the design), it's got a ground pressure of 4 tons per square metre - which is 0.4 kg/cm2. That's less than half that of a Tiger tank.

So it wouldn't necessarily destroy the roads it went on.

The bigger problem is that it has real trouble going through tunnels or over bridges of any kind - though with a 11m height it was just meant to ford, helped by the ground clearance that would let it drive over a standing man.


However, there is a problem in the calculations I've just given.

They assume the P-1000 weighs 1,000 tonnes. And that's nigh impossible.

The intended armour thickness was 10 inches on the sides. Assuming no armour on the roof and floor, and nine metres of armoured side (base to roof), that gives us four armour plates - two 10x14m and two 35x14m - and a thickness of .26 m.

Total armour volume= (2x45x9x0.26) = 210 cubic metres of armoured steel.

At 7.8 T per m3 for rolled steel, the armour alone thus comes to a rough estimate of 1,642 tonnes. Even if this is cut down by the form of the tank, it's very hard indeed to see the whole tank (complete with 20 tonnes dry weight of engine, for example) coming in at 1,000 tonnes.
