Why doesn't the military just design a giant fucking floating fortress with 10ft thick concrete walls that can just...

an RPG-7 can eat through 1 meter of reinforced concrete.Get a 100 of those and your "mothership" goes down in no time.
Also imagine a single Shilka or M163 VADS eating through the concrete like butter lmao.

Build it on the moon- then just let it float around like a satellite

>giant fucking floating fortress with 10ft thick concrete walls

Physics would like a word with you.

Then how come you never hear about any buildings being destroyed by one?

Doesn't drag us any closer to the sun and the sun just floats there even though it's the largest mass around our solar system

This is some A+ trolling. 10/10 really! I really smiled here. Good job user!

What are you, retarded? RPGs are used all the fucking time to destroy buildings in syria

Why is this better than a single nuke?

Thatd be top brittle, itd crack a lot, and something that large requires too much maintenance
A blimp or zeppelin would be better

because its too complicated for its purpose

why not just send missiles from a distance ? or bombs from above ?

cheaper safer just as effective

Simple
>giant fucking floating fortress
It’s that part. You dumb fuck

Good idea user, call the DOD now and explain it to them. It’s likely you will be commissioned on the spot and in charge of it.

Because the raw energy you would need to suspend such an object using electrohydrodynamic force would be many times the safe output of any existing fission reactor? I mean, you might as well be asking why nobody builds an orbital laser cannon.

>10ft thick concrete
It'd weigh less to just use steel, concrete is used in bunkers and shit cause it's cheaper and easier.
If you're devoting a hundred trillion dollars to build an anti gravity fortress the size of a small town you shouldn't cheap out on the armor.

It's literally fucking impossible and would cost a retarded amount of money just to build

Why don’t we artificially create an asteroid out of concrete and launch it into China to destroy our competition without being blamed

It costs $14,000 per pound to put Anything in orbit.

Hold on
Why the fuck hasn't anyone built an orbital laser?

Because the amount of energy that'd be needed to fire such a thing would be able to power the entire eastern seaboard for months.

Why are summerfags so retarded?

If it's so easy, why don't you do it?

Alright, go on. Explain your autism.

I thought it would be interesting to see how large a structure would need to be to meet OP's very rigorous standards, so I did the math.
With concrete being 2406 kg/m^3, Hydrogen (there isn't enough helium on earth to build it out of helium) being 0.083 kg/m^3, 10 feet being 3.048 meters, and the normal density of air being 1.204 kg/m^3, OP's structure needs to have a radius of 19622.023 meters to have the same density as normal air at room temp, and larger to support any thing else. In miles thats a diameter of about 24 miles or 38 kilometers.

No, I don't think it would work.
