The Fat Man is a tactical nuclear catapult in Fallout 3.



The Fat Man has an estimated range of 150+ yards. The blast zone will be irradiated for a short time.

The Mini Nuke projectile is very heavy, and if simply fired straight ahead, it will travel fewer than a couple dozen feet before falling to the ground and detonating (causing you to be caught well within the very damaging mini-nuclear blast). For optimal range, the Fat Man should be fired in V.A.T.S. mode at high skill levels (which automatically compensates for the projectile's downward trajectory), or at an upward angle to catapult the mini nuke further so that it impacts at a farther, safer range.

The launched mini-nuke will fall if shot while in the air.

The Fat Man's condition can wear down surprisingly fast with frequent use (though its firepower is still devastating at any state of repair).


  • Experimental MIRV - An incredibly destructive weapon, the MIRV fires 8 Mini Nukes in a single shot. The damage done by the MIRV is equivalent to the damage done by eight shots with the Fat Man


  • In the basement armory of Germantown Police HQ - an Average locked closet near the firing range.
  • Fort Bannister, in the Fort Bannister Main building in an Average locked room at the bottom of the concrete stairs.
  • Operation: Anchorage. Toward the end of Operation: Anchorage (quest) four American Soldiers with T-51b Power Armor will equip Fat Man, which can be knocked out of their hands and kept using the inventory glitch, thus adding 4 new Fat Man into the game. These four Fat Man can be pick-pocketed from the soldiers, too.


  • After firing the front part of the cradle stretches outward allowing the Mininuke to be placed in with ease, and after priming a bell rings (like on a typewriter, or a Browning Machine Gun) signaling the weapon is primed.
  • Since damage to the player is reduced by 90% when in V.A.T.S., the Fat Man can be used at close range.
  • The damage dealt by the weapon is subject to DR. If you use it at close range, ensure that your character has a DR of 85, which will greatly reduce any collateral damage dealt to the player. Attempting to use this weapon with a 95% success chance in VATS will always deal some amount of damage to the player, as you need to be close to the enemy to maximize the vats percentage, but DR reduces damage to the player character (20-50 hp loss if DR is maxed).
  • When the player encounters the scavenger, it is possible that nearby enemies (Raiders etc) will pick up the weapon. A Fat Man in the hands of an enemy is not desirable.
  • The weapon was made in the pre-war era, since it appears in the Operation:Anchorage add-on. It is used by a squad of Power Armored Soldiers to destroy a large gate of a Chinese outpost.
  • Unlike most weapons and armor in Operation: Anchorage, the simulator version does not have extremely high HP, and will degrade normally.


  • V.A.T.S. incorrectly calculates extra damage for a headshot. The Fat Man does not do extra damage with headshots.
  • If you equip the Fat Man with a Mini Nuke loaded, then drop all Mini Nukes in your inventory, the animation will still show a mini-nuke loaded into the Fat Man. There isn't actually a mini-nuke loaded, and the weapon cannot be fired.

Behind the scenes

  • The launch mechanism of the Fat Man is pneumatic. Coupled with the heavy projectile, this accounts for the short range of the weapon. This type of launch system was first pioneered by the British PIAT anti-tank weapon of WWII, where the projectile was launched from a similar cradle-like contraption using a mechanical spring system (though in the case of the PIAT, was used to detonate a small propelling charge), which had the similar properties of short range and lack of accuracy. This system is known as a spigot mortar.
  • Fat Man was the codename for the atomic bomb that was detonated over Nagasaki, Japan by the United States on August 9, 1945, at 11:02 a.m. It was the second of just two nuclear weapons to be used in warfare and was the third man-made nuclear explosion. The name also refers more generically to the early nuclear weapon designs of U.S. weapons based on the "Fat Man" model. It was an implosion-type weapon with a plutonium core. Early artwork for the Fat Man also included a miniature version of the B-29 bomber the 'Enola Gay' attached to the top of the Mini-Nuke, the 'Enola Gay' being the plane which dropped the first nuclear bomb on Hiroshima.
  • Because of its relation to the real historic event, the weapon was renamed to the Nuka Launcher in the Japanese version of Fallout 3. It is, however, still referred to as the Fat Man in dialogue.
  • The only real-world weapon remotely similar to the Fat Man is the M-388 Davy Crockett, developed by the United States during the Cold War.
  • The bell that sounds after shooting the Fat Man is the lunchroom bell at the Bethesda offices.
