- In a word, overkill. Nuclear weapons effects scale up with yield on a
- Y^(2/3) basis - most targets are effectively flat, while a nuclear
- explosion is a decidedly three-dimensional phenomenon. A 1MT weapon is
- thus "only" one hundred times more destructive than a 1kT device, rather
- than one thousand. Larger weapons are thus inherently less efficient
- against targets of most conceivable hardnesses.
-
- The large yields of older-generation weapons are more artifacts of
- accuracy concerns and manufacturing economics (A 10 MT warhead is about as
- complex as a 1MT, if not more so, and they use about the same amount of
- special nuclear material - the big production bottleneck - so...) than of
- tactics.
-
- Current gravity bombs yield between 50kT and 1MT, often in the same
- device, courtesy of modular nuclear components and "dial-a-yield" schemes.
