Stealth Boy

A Stealth Boy is a personal stealth device.

RobCo Stealth Boy 3001


Invented by Robert Mayflower and produced by RobCo Industries, the wrist-mounted 3001 variant generates a modulating field that transmits reflected light from one side of an object to another. The end result makes the wearer almost invisible to the untrained eye.

After the war, Doc Henry conducts research on the effects of the device, stating that although the prototype's purpose was to use less power. Unintended negative effects of the device's modulating field include permanent neurochemical changes, such as schizophrenia, especially among Nightkin. A chewed variant can be found in the Mojave's Charleston Cave.

Stealth Boy


Stealth Boys were developed by reverse engineering Chinese Stealth Armor. The personal device generates a modulating refraction field, rendering the wearer invisible for a short period of time.

Railroad Stealth Boy


The secretive organization the Railroad gained access to a more powerful variant of the normal Stealth Boy. Their resident engineer Tinker Tom sells the devices to trusted agents.

Stealth Boy Mark III


Developed by Enclave scientists in Appalachia with the help of Chinese schematics and MODUS, the Stealth Boy Mark III was an attempt to improve the Stealth Boy. While not wrist-mounted, the power consumption rate was drastically lowered from the Mark II Stealth Boys allowing for longer duration.
