Nuka-Nuke

The Nuka-nuke is a type of ammunition in the Fallout 4 add-on Nuka-World.

Background
Nuka-nukes, as well as the prototype weapon capable of deploying them, were one of the results of Project Cobalt, a joint secret research program involving the United States Armed Forces and the Nuka-Cola Corporation. The project's main focus rested on the highly radioactive Strontium-90 isotope which, according to various terminal entries found in the Nuka-World theme park, could not only be used to make Nuka-Cola Quantum glow in the dark, but also to "militarize pretty much anything". Applying its enhancing properties to the Fat Man's already devastating ammunition resulted in a warhead with massively increased destructive power that detonated in a bright-blue ball of nuclear fire. Since the Nuka-nuke project was still in its prototype stage when the Great War broke out, they never made it into field deployment. The only known exemplars still reside with the only launcher in existence more than two centuries later, locked away in John-Caleb Bradberton's personal Vault deep below Nuka-World.

Characteristics
Nuka-nukes are a unique craftable version of the standard Mini nukes. They deal 50% more damage than the base model when fired with the Nuka-Nuke launcher, the only weapon capable of deploying them. Aside from looking slightly different and not being available for purchase or looting anywhere else in the Wasteland, they are largely identical to regular mini nukes.

Locations
Three Nuka-nukes can be found at the end of the Cappy in a Haystack quest, along with the Nuka-nuke schematics, by siding with John-Caleb Bradberton over Sierra Petrovita and cutting power to the Vault. These are the only placed Nuka-nukes in the game, but more can be crafted at any chemistry station after picking up the schematics on the same table in front of them.
