General Atomics International is a pre-War company that mass produced robots up until the Great War.


The company is most well known for their Mister Handy, Mister Gutsy, and robobrain robots, as well as for the construction of nuclear power plants and generators. These were used in many vaults and in the American war robot, Liberty Prime.


Mister Handy

Main article: Mister Handy

Mister Handy was produced by General Atomics International as a house-keeping and defensive robot, able to help out around the house and defend itself and possibly others with its buzzsaw and flamethrower. Mister Handy is speech-capable, communicating in a polite English accent.

Mister Gutsy

Main article: Mister Gutsy

Mister Gutsy is a modified Type-II Mister Handy designed for military use by the U.S. Army. Mister Gutsy comes with a plasma weapon, flamethrower, and significantly better armor than Mister Handy.


Main article: Robobrain

The robobrain was created by GAI as a military robot for the US. It uses a real organic brain as its processor. Military models are capable of using integrated laser weapons, sonic projection rays, and have human-enough manipulator claws to wield submachine guns and rifles.

General Atomics Nuclear Power

GAI made Vault-Tec Vault power systems, according to a terminal in the Citadel.


General Atomics International is mentioned in the Fallout manual and Fallout 3, but the company's products appear in all Fallout games.

Behind the scenes

The name is a reference to the real-world corporation General Atomic Technologies Corporation, a nuclear physics and defense contractor headquartered in San Diego, California. It is highly similar to the Fallout version, as it is also a frequently government-sanctioned contractor.
