Mini Nuke (Fallout 3)

The Mini Nuke is a tactical nuclear warhead designed for use in a nuclear catapult and appears in Fallout 3.

A nuclear catapult is a device made to launch small nuclear payloads that are not self-propulsive. The Mini Nuke used as ammunition for the Fat Man and the Experimental MIRV.

A hand grenade electric version of Mini Nuke also exists and appears in Fallout: Brotherhood of Steel.

Fallout 3
Mini Nukes are the single most expensive piece of ammunition, ranging from 250 to 400 caps apiece to buy, depending on your Barter level. They are also ammunition for the single most powerful weapon in the game, doing many times more damage than any other weapon even at low Big Guns levels. These are also great decoration for your house or Tenpenny Tower Suite. This is clearly another reference to the Nagasaki Fat Man because it is an implosion-type bomb like the original Fat Man.

It is based on the W54, a nuclear warhead made by the US Army which can be fired from a recoilless rifle. Although the real life W54 is quite a bit bigger than the warhead used by the Fat Man and Experimental MIRV, it still looks alike.

Weapons using this ammunition

 * Fat Man
 * Experimental MIRV
 * Liberty Prime (a larger version, but less effective compared to its relative size)
 * VB-02 Vertibird
