The One

 is a undetonated bomb in Fallout: New Vegas.

Characteristics
The One is an undetonated nuclear bomb found northeast of the Ranger Station Bravo. You can salvage components (energy cells, microfusion cells and 2 sensor modules) with a science skill of 60 or more. There are three super mutant masters near it(one with a missle launcher, one with a light machine gun, and one with a minigun/the weapons the mutants have may vary). It may be possible to draw the super mutants to the southwest to the nearby Ranger Station Bravo to enlist the help of the rangers there.
