Wikipedia says the B-53 actually uses Oralloy (Oak_ridge_alloy = 90+% pure HEU) and *not* Plutonium! That’s how old it is! Seriously, this is something like a 1955 design. Good for Chevys, bad for nukes. (almost good enough for tagline material right there)
Thing is > If we really, truly needed it for asteroid repulsion, I’d want a much lighter (and thus more reliably launched) and newer (more reliably fired) device, I think. When it comes to frying Mecca, I wouldn’t be as picky. (just not really kidding)
