| ||For an overview of this weapon in the Fallout series of games, see Fat Man.|
The Fat Man was conceived, developed and tested inside the Fort Strong armory in Boston. The barracks were leveled and several houses were constructed around the fort to provide a testing area, to better ascertain how much damage the weapon would cause in an urban environment.
In June 2075, General Brock, the commanding officer at the fort, was placed in charge of developing the M-42 launcher and testing the newly-minted T-51b power armor, and dedicated half of his team to each project. The team in charge of the launcher first attempted to lower the weight of the warhead, and later tried to increase the power behind the firing mechanism, but both designs failed to produce satisfactory results. In both scenarios, the explosions were far too close to the soldiers firing the launcher, either killing them in the blast or soaking them in lethal levels of radiation.
After almost two years, and the loss of a testing squad due to a misfiring weapon, the engineers behind the project built a fusion sub-charge into each warhead, greatly increasing the launcher's range, and the design proved successful. In September 2077, the launchers were shipped from the fort to a supply yard in Mississippi, and from there to the Chinese front.
The Fat Man is a portable heavy weapon that launches mini nukes at distant targets in an arching trajectory.
If the Fat Man has the MIRV launcher mod, the Fat Man needs to be aimed such that the trajectory of the mini nuke reaches apogee above the target, as opposed to aiming such that the mini nuke hits the target or adjacent ground. When a Multiple Independent Reentry Vehicle mini nuke reaches apogee, it stops and splits into four projectiles. These projectiles fall straight down, detonating if they don't hit anything after falling 100 feet or 30 meters.
Always fire a MIRV-modded Fat Man, including the Daisycutter which usually spawns already having the MIRV mod, with at least a few degrees of upward angle. If you fire a MIRV-modded Fat Man while the weapon is aimed horizontally or down, the mini nuke will split immediately after leaving the weapon, fall at your feet, and detonate.

Behind the scenesEdit
"Fat Man" was the codename for the plutonium atomic bomb that was detonated over Nagasaki, Japan on August 9, 1945. With the exception of the tail fins, the mini nuke has a striking similar look to Fat Man.
