Question

my brother keeps telling me that the u.s has a is 200 Megaton bomb? i dont believe him

Answer 1

The U.S. nuclear arsenal is based on the idea of relatively low-energy warheads delivered with near pin-point accuracy. A large warhead for the U.S. would be in the megaton range. Most of the ICBM and SLBM warheads are around 0.5 megatons. Here's a list of all the warheads deployed by the U.S. The ones at the bottom are those still ready for use.

Answer 2

The biggest bomb humans have ever made was the Tsar Bomba. It weighed in at a hefty 50 megatons. The original design had a yield of 100 megatons. I doubt that the U.S. would bother to make a 200 megaton bomb. It's just too inefficient. Most of the energy would be radiated off into space. Such a bomb would only be to intimidate or show off.

Answer 3

I think they have gotten up making ones of 60-100 megatons; if that isn't big enough for your particular application, you could always put 2 or 3 together with duct tape!
