Do neutron bombs still exist?
Although no country is currently known to deploy them in an offensive manner, all thermonuclear dial-a-yield warheads that have about 10 kiloton and lower as one dial option, with a considerable fraction of that yield derived from fusion reactions, can be considered able to be neutron bombs in use, if not in name.

What is the B61 upgrade and why is it controversial?

Furthermore, the yield can be adjusted before launch, according to the target.
Where will the upgraded b61-12s go?
“The issue has a particular significance for Europe where a stockpile of 180 B61s is held in six bases in five countries. If there is no change in that deployment by the time the upgraded B61-12s enter the stockpile in 2024, many of them will be flown out to the bases in Belgium, the Netherlands, Germany, Italy and Turkey.
What is the b61-12 life extension program?
This life extension program will address all age-related issues of the bomb, and enhance its reliability, field maintenance, safety, and use control. With these upgrades and the addition of a U.S. Air Force- supplied Boeing Tail Kit Assembly, the B61‐12 LEP will consolidate and replace four B61 weapon designs: 3, 4, 7, and 10.
What is a B61 nuclear gravity bomb?
