"We knew the world would not be the same. Few people laughed, few people cried, most people were silent. I remembered the line from the Hindu scripture, the Bhagavad Gita. Vishnu is trying to persuade the Prince that he should do his duty and to impress him takes on his multi-armed form and says, "Now I am become Death, the destroyer of worlds." I suppose we all thought that, one way or another."

— J. Robert Oppenheimer, looking back on the first nuclear bomb test

Credit should be given to nukes for being the only weapons that, after their initial use, were so frightening that humanity has done everything it could not to use them again. That still doesn't change the fact that nukes are awesome. Until one, hopefully not, goes off above your head, or just in close proximity to it. And even then it's pretty awesome … for somebody else witnessing from outside the fireball and blast radius. You, on the other hand, will be vaporized faster than any neural signals could travel to the brain, let alone be processed into actual perception, and will cease to exist without ever knowing that anything happened at all. And that's not even mentioning radioactive fallout, which can spread for many, many miles following the explosion, and can kill many more people through radiation poisoning.

All deployed systems designed solely for nuclear use
All aircraft, missiles etc. with nuclear capability, or a nuclear capable variant.
Any planned nuclear-capable platform that did not enter service or entered service in a non-nuclear form only if it was obviously intended for a nuclear capability. Therefore the Seawolf-class attack sub is included in Superior Firepower as it was a Cold War design intended for nuclear-use. The Virginia design occurred afterwards, so isn't. The same applies with Russian carriers- Admiral Kuznetsov is included, the new planned carriers are not. If a ship was laid down, it's included.
