The Fat Man is perhaps the most devastating infantry weapon ever unleashed upon the modern battlefield - a hand-held catapult that launches portable nuclear bombs.”— Fallout 4 loading screen hints
The M42 "Fat Man" Launcher is a shoulder-fired, catapult weapon system that launches tactical nuclear ordnance, the "mini nuke". It appears in the following games: Fallout 3, Fallout: New Vegas, Fallout 4, and Fallout Shelter.
Background[edit | edit source]
The M42 Fat Man was developed at Fort Strong near Boston, Massachusetts. Development began in February 2076, with the goal being the development of a man-portable tactical nuclear launcher easy enough for use by troops on the ground, to destroy reinforced and entrenched positions. Problems manifested instantly, as warheads were simply too heavy to clear the blast radius fast enough to provide safety for the operator. Even stripping them to the minimal possible size failed to produce an acceptable effect. Instead, the development team decided to increase the power of the launcher unit, even considering using railgun technology to accelerate the warhead. The notion was largely academic, as it would require for the overburdened soldier to carry an additional power pack the size of a suitcase and turn the Fat Man into a crew-served weapon. Concurrent development ran on the MIRV version of the launcher. Live-fire testing claimed lives, in fact, with two soldiers killed during a test. No remains were recovered and the commanding officer in charge of the project, General Brock, covered up the incident, ordering his subordinates to send sand packed in an urn to their relatives.
The project hit a breakthrough in December 2076, when the project lead discovered a solution for the launcher problems. Six hours, fourteen cups, and one concerned night shift lab crew later, the future M42 launcher was conceptualized: Based on the spigot mortar mechanism, the launcher would only have to accommodate a firing through and system, relying on mechanical launching, rather than chemical or electrical means. Much like the 130 year old PIAT launcher, the Fat Man warhead would be propelled by a sub-charge embedded inside the warhead, "catapulting" the warhead through the air to the target - giving plenty of range with the added bonus of not producing a smoke trail that could reveal the firing team to the enemy. By September 2077, after one hundred test firings the weapon were complete and ready to be shipped to units overseas. A large number of units was manufactured and shipped together with the appropriate warheads to select locations throughout the United States.
Variants[edit | edit source]
Fat Man[edit | edit source]
The standard M42 "Fat Man" Launcher is a man portable nuclear payload, anti-materiel weapon platform. It was designed for mid-ranged combat in urban centers where cover was high, but chances of survival were low.
Experimental MIRV[edit | edit source]
Named for the multiple independently targetable reentry vehicle (MIRV) ballistic missile payload, this variant of the M42 "Fat Man" Launcher fires eight mini nukes at once, arguably making it overkill for any application due to its more plentiful payload and larger spread.
Esther[edit | edit source]
Esther is a unique M42 "Fat Man" Launcher with a different rear mechanism, a blast shield, a light-blue body, and a thick glass or plastic bed holding the mini nukes. It weighs 10 pounds more than a standard M42 "Fat Man", but does not jam, and protects the user from damage.
Behind the scenes[edit | edit source]
- The names of Fat Man and Little Boy are references to the code names of the atomic bombs dropped by the United States on Japan during World War II: Little Boy was dropped on Hiroshima while Fat Man was dropped on Nagasaki. For this reason, the weapon's name has been renamed as the Nuka Launcher in the Japanese translation of both Fallout 3 and Fallout: New Vegas due to its relation to Japanese history. However, the Little Boy modification still retains its name.
- The bell heard after reloading is actually the lunch bell at Bethesda.
- The designation M42 is shared with a couple other pieces of military equipment, such as the M42 Duster SPAA gun and the M42 submachine gun.
