for the german government its officially a conventional weapon but now its a proved fact that ALL 6 hydrogen high tech submarines will be equipped with Nuclear long range rockets.
It is questionable whether a country like Israel needs nuclear equipped supmarines for self defense.
because a "Genocide" is never self defense! and the and the crazy muslim brotherhoods will provoke Israel to start a Genocide with there nuclear weapons !
Israel had nuclear weapons in the past and this dosn't stop any ""crasy muslim"" to attack them
in my point of view: you can't use nuclear weapons without killing innocent because of this nuclear weapons are complete useless for "Self-Defense" it will not work at all.
