Nuka-Nuke Launcher

The Nuka-nuke launcher is a weapon featured in the Fallout 4 add-on Nuka-World.

Characteristics
The Nuka-nuke launcher is a Fat Man nuclear catapult with a unique modification. Instead of regular mini nukes it launches Nuka-nukes, a specially modified, quantum-enhanced version with increased explosive power.

The launcher deals 50% more damage than its basic counterpart and is therefore the second-most powerful weapon in the game, outclassed only by a Fat Man with a MIRV modification or the legendary Two Shot prefix. While it cannot be outfitted with the MIRV mod itself, it retains the advantage of the standard Fat Man's much longer range.

Apart from its superior damage output and its unique ammunition, the Nuka-nuke launcher looks and handles exactly like its base version.

Weapon modifications
The Nuka-Nuke launcher is a stand-alone modification similar to the craftable MIRV mod. It can therefore be detached from its original carrier Fat Man and attached to another one, like Big Boy for instance, to benefit from any legendary weapon effects the new carrier weapon might bear.

Variants

 * Fat Man
 * Big Boy, a unique version with the Two Shot legendary modification.
 * The Striker, a unique version that fires modified bowling balls instead of mini nukes.

Location
Found at the end of the Cappy in a Haystack quest in the vault below John-Caleb Bradberton's office, along with three Nuka-nukes and the schematics to craft more ammunition, by siding with Bradberton over Sierra Petrovita and cutting power to the vault.
