|For the unused note in Fallout 3, see Megaton's atomic bomb.|
For the world object in Fallout: New Vegas, see The One.
Undetonated nuclear weapons found in the Capital Wasteland. One bomb is situated in the center of Megaton. In 2277, Confessor Cromwell of the Church of the Children of Atom preaches on a daily basis from the foot of it, calling others to join him in worship of the object. Some citizens believe that the bomb caused the crater, but Manya shares that this was not the case. There is a warhead storage room at Fort Constantine that holds 22 atomic bombs, on two racks of 11 each. The righthand side rack has broken, the bombs falling within it down to the row below.
- Megaton - In the middle of the town's crater.
- Fort Constantine - The fort's warhead storage contains 22 bombs.
- Sacred bog - During a hallucination, one is visible.
- The Power of the Atom - The Lone Wanderer is given the choice to detonate the bomb with a fusion pulse charge or to disarm it.
- Walking with Spirits - After consuming Mother Punga seeds in the Sacred Bog, the Lone Wanderer sees a bomb during a hallucination.
The Megaton atomic bomb only appears in Fallout 3.
Behind the scenes
- In the Japanese version of Fallout 3, the option to detonate the bomb during the Power of the Atom is not available due to the removal of the NPC Mr. Burke.[Non-game 1]
- An unused part of the megatonatomicbomb01.dds texture in the game files reads "C-23 Megaton."
- Fallout 3 loading screen: "The members of the Church of the Children of Atom worship Megaton's atomic bomb."
- The Lone Wanderer: "What's this place made of?"
Manya Vargas: "Long ago, before the war, there used to be machines they were like buses, but they flew through the sky, taking people anywhere they wanted to go. You didn't have to walk, you just went to the air station, bought a ticket, and took to the skies. Anywhere in the world, you just up and flew there. When the war happened, the machines started dropping from the sky. Everyone around here thinks that the bomb made the crater, but it didn't. The crater provided good cover from the dust storms and when my daddy and the rest of the town decided to build the walls, they used what they had."
