There are physical limits to weight, hardness, max explosive energy and max kinetic energy and these are all known. The only way to exceed them would be to drop it from a higher altitude, like space, or give it a nuclear warhead. The US isn’t the only country that has tested bunker busters and the physics involved isn’t that hard. It’s just expensive.

Sure, but you have no firsthand knowledge of that information.

You are told the B2 can carry a certain payload weight.

You are told the B2 has a certain operational ceiling.

You are told the bombs are a certain weight.

You are told the bombs are made from a certain material.

You are told the bombs contain a certain type of explosive.

Everything you know about this device and its capabilities came from an organization that has every motivation to publish specs that are just enough to raise the eyebrows of the people this device is supposed to scare hell out of, but they have less than zero motivation to publish specs that speak to maximum capabilities.

So while your calculations might be accurate for the component values you gave it, your component values of your calculation are not accurate, because all you know is what you were told.

You can calculate these things based on wing size and airspeed and neither are hard to figure out, it’s clearly subsonic and it’s been seen in public.

While skunkworks are certainly a thing they’re not hiding some Star Trek antigravity device, physics is still physics and physical limits are physical limits. Look at the Otto Celera 500L if you want to see what attacking physical limits looks like. It’s an engineering problem and the fundamentals are well understood. The real magic is in creating the money to pay for it.

If you can calculate the depth and damage those bombs did based on wing size and airspeed (which technically is another parameter you really don’t know, but are relying on what you are told) you ought to be working for the government.

The US military isn't the only entity making airplanes and bunker busters. We don’t need to rely on their figures to know a great deal about what happened. You are assuming they have some order of magnitude hidden capacity which would break the laws of physics, and I’m very confident that they didn’t do that.

[kcplate]

Gotcha. So your perspective is there are other entities making airplanes with the capabilities of the B-2 and a bunker buster bomb equivalent to the GBU-57 so much so that you can reliably determine capabilities of those weapon systems…as a layman with just a hand calculator?

That is a $2B aircraft and a $20M ordinance (each). You want to tell us exactly what entity has anything even remotely equivalent? No one else but the US could bear to afford it. Maybe China…but if they have it’s not common knowledge.

I think you have pretty much dug yourself a hole here on your knowledge and capabilities…you have landed into silliness now. (That pun was definitely intended)

[cjbgkagh]

No amount of money enables an aircraft to violate the laws of physics. Clearly your knowledge on aircraft is limited otherwise we would have a shared understanding of the physics involved and wouldn’t even be having this argument.
