If Harold is originating from V 29, he shouldn't get there because of random wandering. He should be accquainted with specific culutre there and should know about godess Diana. So rather Vault 31 is Twin Mothers home. Or beliefs concerning Harolds origin are wrong. dotz

He is from Vault 29 and Twin Mothers is Vault 29. I got a more detailed explanation from John Deiley and will post it here soon. Ausir 20:33, 14 November 2007 (UTC)
I don't recall a Junktown Vault, did I miss something along the way? ZasZ 23:05, 12 August 2008 (GMT)
It's not the actual Junktown, it's the Vault from Van Buren tech demo. Changing the article to clarify it. Ausir 22:11, 12 August 2008 (UTC)

Why are Vaults made up by some webcomic in here? Does this mean I can just make up a Vault and put it in here? These are not canon, and if they must be in the article at all, should be in a seperate section, though ideally should be removed altogether.

It's not just some random webcomic. It's not the regular Penny Arcade comic, but the official Fallout 3 comic made by the authors of Penny Arcade in cooperation with the FO3 lead designer, featured on the official Fallout 3 site and referenced within Fallout 3 (see: Vault 77 Jumpsuit). Ausir 11:28, 1 December 2008 (UTC)

Odd question, maybe it should have it's own category, but do any of the games specify the procedures taken for actually entering the vaults? Perhaps a log with someone's recounting of the sirens going off, or some such? Did they report in an orderly fashion, did non-members try and get in, or did go in in advance? TheDunham 03:08, April 3, 2010 (UTC)

Vault doors

The vault doors are 4 yards thick? Really? 12 feet, or 3.6 meters? That's a heck of a thick door, sure it's not 4 feet? In all three games, the vault doors don't seem THAT thick. --DarkJeff 19:43, 8 December 2008 (UTC)

I agree Vault 815 01:30, September 29, 2009 (UTC)

Does anyone know where the 4 yards came from? 4 feet seems to be about right. - Redmess 01:45, November 8, 2009 (UTC)

Four feet seems to be the measurement that looks closest in all the games. Whoever said four yards doesn't know very much about measurements. Creedofheresy 00:40, March 26, 2010 (UTC)

Hello. The 4 yards comes from information accessed on the Vault 13 mainframe in Fallout 2. This isn't to say that the measurements are sound, but it does indeed come from F2.-- 20:15, 3 December 2012 (UTC)

Is it just me?

Or are some of these "experiments" a bit stupid. for example, who cares about how 1 man reacts to 1000 women, maybe 1 women to 1000 men, (the enclave is basically all male), and a man with 4 puppets, what? 20 men, 10 women , and a panther? Half of these don't make sense, and only work in one way. the 30 people and panther, maybe as a "how would a small people live and react in a small settlement and eventually discovering that there was a a killer animal after them, but unless the vault armory was empty, that would've been stupid! and what about the 70 clones? what, a short term repopulation test?

Well there WERE a lot of vaults so they had some spares to do some "other" tests. Seriously though, the 1 man 1000 women is a pretty interesting test. The panther one not so much, but remember what some of the others were too. Exposing the occupants to such things as subliminal homicidal messages, or insanity gas. Or the vault designed to fail starting with it's overseer ("Gary!"). Or the one designed to keep the people in "relaxation chambers"? The point of the experiments is to have a random situation that can only occur in a vault-like environment and see what comes of it.
well, the puppets is a psychological test on how the brain copes with lonelyness, and as it turns out, it copes with schizophrenia! the 1 man and 999 women, well repopulation and probably a joke (being vault 69) the panther though... im at a loss

I agree. The experiments all seem completely useless to me. I mean social conditions and all that blah, but does that really matter if those who the information might matter to are dead? A better experiment, or atleast more useful to an apocalyptic area would be a Spartan esque, raised from birth to kill, or to heal, or to farm etc.\

Some of the experiments are stupid, but most could be used to catalog the reaction of the mind. Also, DOES NOBODY SIGN THEIR POSTS ANYMORE? Vault 815 15:12, January 26, 2010 (UTC)

Vault 101

Vault 101 was never intended to stay shut. I remember reading that it was the overseer's doing.

No, i'm pretty sure if you check the Vault-Tec computer that explains each of the vaults, 101's purpose was to test "Indefinite Isolation". It WAS the overseer's job to make sure that things stayed that way.
No, Vault 101 was an experiment focusing on the Overseer himself, how he'd perform. That Furry Bastard 09:00, 18 March 2009 (UTC)
No, you're BOTH right. It was a test of Indefinite Isolation AND how good of a overseer would be. Plus, the vault was opened at some points, and more and more people were told....so I guess that just scratches Isolation.-- 03:19, June 21, 2010 (UTC)
Uh, no. The original mission was Assessing the Overseer. The "indefinite isolation" part was added after the failure of scouting parties. http://images1.wikia.nocookie.net/fallout/images/0/08/Personal_Sig_Image.gif Tagaziel (call!) 06:25, June 21, 2010 (UTC)

Pitt Vaults

I wonder if there would be any vaults in The Pitt. I dunno if its plausible though, what do you steelworkers think?Jetholt (Jetty) 20:56, 23 March 2009 (UTC)

I had hoped so. I saw a 'Vault Secure' billboard just before the bridge into The Pitt and I thought that the area had a vault somewhere. - Dweller93 08:54, 23 April 2009 (UTC)

Possibly, I mean all those factories are really run down. No way could the ancestors of the slavers/slaves of survived the great war in them. This also begs the question, were there vaults for the soldiers in Anchorage, Alaska? It's still US soil and the US Army defending a state would obviously be a top priority to the Enclave.Bravo315 No No the Brotherhood of Steel descends from the US Army and they had no vaults... - Bio Enhancment 411 13:41, 27 August 2009 (UTC) Plus a vault would be far to dangerous and costly to buils a frikin WAR ZONE!, with the chinese bombing all the military instillations they could there would be no chance to do anything for the soldiers.Bio Enhancment 411 20:03, October 13, 2009 (UTC)

V13 the last vault

What is the source for saying that V13 was the last vault constructed? I've checked both manuals and cant spot it there... Agent c 23:04, 14 April 2009 (UTC)

Timeline from the Fallout Bible. That Furry Bastard 23:19, 14 April 2009 (UTC)

Found it - The speicifc Primary source is Bible 0. Agent c 23:32, 14 April 2009 (UTC)

Wouldn't it be vault 122? as it is the last in the number line?

No, vault 122 wouldn't be. As I recall, vault were created by humans, which means if the conditions are bad, there is a strike (Which happened to one vault).

What experiment!?!?!?!??

I know the vaults were an experiment, but I only learned that from visiting this site! I'd played Fallout and Fallout 2 at the time, but I NEVER heard of any of this!!! How did I miss it? What was the in-game source of the experiment?!

In Fallout 3(Play it its awesome) YOu can visit Vaults 87, 92, 106, 108 which respectively do experiments on FEV, A white noise which has combat sequence drives ppl mad, Halucination gas, Cloning(GARYS).. And there are files about it how the experiments are done and everything.. Vaults were never meant to save lives.. (PS: I may be mistaking 106 and 108) -- 13:53, 27 August 2009 (UTC)NightPhoenix

Or maybe they were and just some were used for testing purposes? 01:56, September 7, 2009 (UTC)

Last Vault

So what was the last vault ever created? 112? -- 23:43, 3 August 2009 (UTC)

Nevermind, just saw the article said Vault 13 was the last. But why would they finish with 13 before 112, 101, and others? Seems kinda odd. -- 23:53, 3 August 2009 (UTC) 17:18, 22 August 2009 (UTC)

Vault 13 was beset by technical issues if I recall the Fallout Bible correctly.--Ishotamaninnewreno 09:53, October 3, 2009 (UTC)

Uhhhhhh maybe... just maybe the number of the vault, (101, 87, 13 etc) is the order in which they were PLANNED and then some took longer to build that others.... technical complications or more complicated systems, power manegemant etc...Bio Enhancment 411 19:56, October 13, 2009 (UTC)

Jumpsuit Extruder?

Under Vault 70, it is stated that the "Jumpsuit Extruders" Failed after 6 months. What does that mean? I mean, Vault 36 states that food extruders, which i assume were the food source, only produced a thin watery greul. What do jumpsuit extruders do? Produce jumpsuits or something?--Ih8pkmn 00:28, January 10, 2010 (UTC)

You've answered your own question. http://images3.wikia.nocookie.net/fallout/images/thumb/4/4a/Naglowaa_se.gif/11px-Naglowaa_se.gif Tagaziel (call!) 18:37, January 10, 2010 (UTC)


Hey, relax. You guys worry too much. I've even reserved my family's place in vault 87, if it wasn't for Vault-Tec, I don't know what I'd do!

might i suggest Buddhism?
How the hell can you afford a space in a Vault-tec vault? When the sirens ring, my family will hide in the metro and hope for the best.

Metro? I"m Going For A Closet!!! 00:23, June 27, 2010 (UTC)My name is gary and they practically invited me to 108!

Vault mechanisim mystery

So, in F1/2, something pushes the door out, and a claw pulls it aside. What is the something that pushes it? Oppositely, in F3, a large screw device pulls the door in, and something rolls it aside. What is the the something that rolls the door? 18:36, April 29, 2010 (UTC)

F1/2: Hydraulic press the door rests on. http://images1.wikia.nocookie.net/fallout/images/0/08/Personal_Sig_Image.gif Tagaziel (call!) 20:39, April 29, 2010 (UTC)
Fallout 3 has a big arm that rolls the door to the side. - 09:12, June 13, 2010 (UTC)

Food extruders?

Just a few questions. How do these work? In Vault 87 it says that tapioca pudding came out orange, and some guy fixed it so it comes out the right color. Also what do they look like? I only own Fallout 3 and nothing in those vaults looks like it's meant to dispense food. And If they have these why do they need kitchens.

Wouldn't YOU put the food extruder in the kitchen? And you need to do the dishes and store plates/glasses somewhere. As for the orange pudding: food coloring. Did you know our food is full of the stuff too? Interesting things happen if you stop adding these. - 09:10, June 13, 2010 (UTC)

Inflation/Actual Prices

So, if a car would cost a million dollars in the game universe, and a normal car costs ~20k....doing a few calculations, a vault would be around 12.9 million in the end of construction, modern times.
    • Might want to recheck your math! Its 1/50th of $645 BILLION and not million. So, assuming that prices inflated on automobiles and large construction projects at the same pace (they probably wouldnt!) that would make a Vault today cost about $12.9 Billion. In comparison, our newest aircraft carrier, the USS Reagan, costs between $4-5 billion, and the US Government has the 600k sq foot Mount Weather facility that cost approx $7 billion AFI ($1 billion in 1962) and the famous Mt Cheyenne Complex cost $4.7 billion AFI ($695 million in 1965). Those are both about Vault size Id say, if a bit smaller by comparison.
If Vaults cost $12.9 billion each today that would mean a budget for Project Safehouse of $1.5 trillion. IMO, and this is just speculation, they cut costs on many of these Vaults and secretly diverted funds to the Enclave for their military and facilities buildup. 18:11, July 8, 2010 (UTC)Kanid

Vaults: Fallout: New vegas

All map locations of the New Vegas vaults added on the wiki!

Securitron Vaults?

There are two securitron vaults in the vault list, problem is, it's the same vault. Where should it go? The Yoshiman 22:07, November 20, 2010 (UTC)

Ausir removed at least one. If one is still there, it should also be removed as per Ausir's edit description. --Kris User Hola.jpg 23:01, November 20, 2010 (UTC)

Ausir said it the securitron vault wasn't a "Vault-Tec" vault, so he found the duplicates and removed both. Problem solved. The Yoshiman 02:55, November 21, 2010 (UTC)

Vegan Diet?

If the vaults grow their own food with hydroponics, doesn't that mean they would not be able to have any animal products? Just wondering.

Vault 77 loaction

I found Vault 77. In fallout 3, go to the Arlington cemetary and look for a set of pillars, look between these structures and you will eventually find a cave. Inside is a giant radscorpian and the Vault. Inside the vault as proof is a crate of puppets.

No it isn't, that's a mod. --Kris User Hola.jpg 23:20, December 7, 2010 (UTC)


In the bad (HORRIBLY BAD) ending in Fallout the master's mutants...ripped the goddamn door O_O, wasn't it supposed to be NUKE-PROOF? maybe was just a lie to make the vaults look safer, maybe beteshda messed cannon again or it could be that Vault 13 had a old model door as it looks different from those in new vegas and FO3.

Actually, they used a shaped explosive charge, not raw strength. Even supermutants can't pull a multi-ton steel door off the hydraulic press. http://images1.wikia.nocookie.net/fallout/images/0/08/Personal_Sig_Image.gif Tagaziel (call!) 19:09, January 1, 2011 (UTC)

Unknown Vault

Do we know this is a Vault Tec Vault? How do we know it was cut and not just mentioned? And finaly, anyone think maybe it's Vault 36? The Emporer 02:37, January 19, 2011 (UTC)

In regards to that vault, it sounds to me like the actual residents weren't cannibals. The attackers were probably people who tried getting in, couldn't, and instead took to killing and eating those that tried to enter after them. --PW12 03:49, January 23, 2011 (UTC)

122 vaults

Can someone add a reference to the 122 vaults. Because this may change or is incorrect. K'jal'mar ( The talk| Contribs) 23:07, February 10, 2011 (UTC)

Apparently this figure is from Fallout Bible 0 -LawdyMissMaudy 01:57, August 26, 2011 (UTC)

The Burkittsville vault

When I read the terminal entry that mentioned the Burkittsville vault, it did not strike me as it was the inhabitants of the vault that ambushed Frank.

In the description list of all vaults, it says: "The inhabitants are cannibals, wear the skins of those they kill, and ambush people attempting to reach the Vault."

In the terminal entry, it says this: "He tried getting into a Vault near Burkittsville. They wouldn't open up and he was almost killed in an ambush on his way out of there. He said those folks wore skins of men. Cannibal bastards must just wait for their next meal to come looking for help at the Vault."

Actually, in the page about the Burkittsville vault, I think the author got it right: "A group of crazed cannibals set up camp near the Vault entrance, ambushing anyone who tried to reach it."

And because of this, I am actually kind of interested in this vault. But I don't want to go back to Maryland :P

2% Chance of Failure

Given the fact that Vault 87's blast door broke, isn't it also a possibility that the vault was hit by a number of nukes instead of a single one? This must have been a primary target of the Chinese because they hit it directly, likely because of the FEV virus experiments going on there, and logically they must have known that the vault was heavily fortified against such an attack. Wouldn't it make logical sense to assume they would try to hit it with more than a single nuclear weapon? Or they could have hit it with a higher than average yield with the intention of destroying the facility? In such a case then I think the doubt expressed over the 2 percent chance given by the museum of history of a vault door failing against a nuclear blast is unwarranted, because of the possibility that the Chinese would have hit this compound with more or more powerful nukes than this percentage is meant to predict.

Dead People

What do they do with their dead. Do they cremate them and use them as fuel like in Brave New World or what do they do?

Some are buried and have crosses to mark their graves in several locations, other than that the dead are usually left were they die. Saxony4 09:12, June 8, 2011 (UTC)

Soylent Green is people :P -Dude101

Penny Arcade?

Why is Penny Arcade cited as a source for vaults? I didn't know they were the authority on such things. 01:35, June 13, 2011 (UTC)

Failure rate right?

Vault 87 falling in the 2% failure rate seems right. Though Vault-Tec didn't think a nuclear apocolypse was imminent, Vault 70 survived several direct hits on its area; Salt Lake City, which is described by Randall Clark as being near unrecognisable after the war. Just a thought that though nuclear war was unlikely to Vault-Tec they didn't fabricate the failure rate.

Also, something strikes me as odd that they built Vault 21 in Las Vegas by the fact they were apparently building them away from 'nuke hotspots'. Even if they thought war wasn't going to happen, wouldn't it have been safer to build it away from the city just in case? (like most other Vaults). Vegas turned out to be a hotspot and if not for House could've been like Salt Lake City. All that would have kept the gambling social experiment Vault going would've been it not failing when hit. Nimbus Recanto 23:52, June 27, 2011 (UTC)

Since many vaults were located around Los Angeles and Washington, DC, two definite nuclear war "hotspots", I felt that this was extremely inaccurate speculation, and I deleted it. -LawdyMissMaudy 02:53, August 13, 2011 (UTC)

I agree with the OP here for a different reason. Vault 87 was doing legitimate weapons testing for the FEV virus. If the Chinese knew they were weaponizing FEV here (not unreasonable) and that it was located withint a vault this could account for the vault 87 malfunction. These two facts together mean that it would be a primary target for nuclear warheads and also they would be making the attempt to actually destroy it. And when we look at it from the perspective of the game we see that the door to the vault is the only completely lethal area in the game from nuclear weapons 200 years ago. This leads to the conclusion that significant nuclear resources (multiple nukes, higher yield nukes) were used to destroy this vault while comparitively the average vault may or may not take an indirect blast, resulting not in its destruction but merely the failure of its vault door. So the vault 87 failure could and should be disregarded as it was not an actual vault but a military installation and thus target, the failure rate otherwise would hold. 09:41, September 4, 2011 (UTC)

Entertainertrons and Eye-on you bots

What are these? They are mentioned in the article as being in Vault 101, but I'm totally unfamiliar with them. Can't find any other reference to them on the wiki, either. -LawdyMissMaudy 02:55, August 13, 2011 (UTC)

Taking a vehicle inside a vault

Ok I have been wanting to ask the question why they didn't take a vehicle in the vault.Like a car they could just take it apart and put it inside and then put it together when they leave.If that doesnt work why not just a motorcycle.They could easily find gas at the abandoned gas stations or just take gas in with them. I just want to know if anybody can tell me.

The question isn't "why didn't they?", it's "why would they?". What's the point or a motor vehicle when the corridors are four feet wide and the farthest you ever have to walk is at most a mile? It would be totally unnecessary. Vaults were made to fit asany people as possible inside; you don't need an needed car taking up space you don't have. --Kastera (talk) 06:55, 26 November 2011 (UTC)
