Mini Nuke (Fallout 76)

The mini nuke is an ammunition type in Fallout 76.

Background
Developed at Fort Strong as part of the M42 Fat Man project, the mini nuke is one of the most powerful conventional weapons ever devised. Though the project was plagued by design issues from the beginning, caused by the weight of the micro-nuclear warhead and the resulting low range, the designers eventually happened upon a breakthrough: Instead of trying to reduce the weight of the warhead or the power of the launching system, one researcher proposed falling back on the spigot mortar system, used over 130 years before in PIAT launchers. The ingenious solution was just what was needed to complete the project and by September 2077, the first M42 Fat Man weapon systems were sent to ordnance depots across the United States.

The mini nuke consists of four principal components. The detonator shell on the bottom contains a conventional sub-charge that detonates when struck by the M42's striking pin, catapulting it out of the launcher. Four stabilizer fins attached to it ensure a stable trajectory and prevent tumbling in flight, increasing accuracy (a necessary feature, as the projectile is not spin-stabilized). The hemisphere core is screwed onto the top, containing the nuclear core. Finally, the weapon is fitted with a beryllium contact fuse that starts the nuclear reaction on impact. 

Characteristics
A small, football-sized nuclear bomb, as rare as it is powerful.
