I heard something about modern US Aircraft Carriers being able to do something like 50-80 knots at top speed, and that it is supposedly classified information.
I can't remember where I heard this, but I distinctly remember hearing something about that, from whatever the source may have been.
It just doesn't seem possbile to me, however.
As well, I also heard about how the US, Canada, and Britain in WWII conducted experimenting with Arctic Aircraft Carriers, which were made entirely out of some kind of super packed ice, or something like that. The ice had some kind of special name, which I can't seem to recall.
Apparently, those Ice Aircraft Carriers were never commissioned, for whatever reasons.
Anybody else hear about any of this?
