The B61-12 and W88 are strategically important weapons in our nation’s nuclear deterrent. The work done on these programs is critical to our nation’s defense plans for many years to come.
Some variable yield nuclear warheads such as the B61 nuclear bomb have been produced in both tactical and strategic versions. Whereas the lowest selectable yield of a tactical B61 (Mod 3 and Mod 4) is 0.3 kilotons (300 tons), [ 19 ] modern PAL mechanisms ensure that centralized political control is maintained over each weapon, including their ...
The Bush administration was unsuccessful in its goal to develop a guided low-yield nuclear weapon, however, in 2010 President Barack Obama began funding and development for what would become the B61-12, a smart guided low-yield nuclear bomb developed off of the B61 “dumb bomb”. [35]
