This has been bothering me lately, but I'm wondering, do you guys think it fits for the Fallout Universe, because I don't think it does. FIRST, if the T-60 was so advance how come the majority of the brotherhood of steel in California is wearing T-51. SECOND, In canon lore, the T-51 was one of the most advance power armors, every (well the majority) of the US army wore this after the the defeat of China in Alaska. Sorry but I will never accept the T-60, Bethesda should get a better writing team.

I thought the Brotherhood developed the T-60 on their own between the events of Fallout 3 and 4.

In the intro, you can see the T-60 in action. Also once you get to the gate (where Vault 111 is) you can see two guards wearing the T-60.


Skip to 14:07 and you will see.

From the wiki:

"According to loading screens in Fallout 4, T-60 power armor was the last model of power armor produced by the U.S. military and distributed to American troops. It entered service after the Battle of Anchorage, and was deployed within the U.S. alongside T-51 models to maintain order in the final days before the Great War."

If it were deployed after Anchorage, that only leaves the invasion of China and quelling of rioting at home as it's roles; as the most advamced armour system, it would likely be mostly in use in China whereas more T51's were available at home.

Plus, the western brotherhood descend directly from the Army unit stationed at mariposa. You're not gonna give the ultra ultra advanced stuff to the guys guarding a research facility when you have soldiers fighting a war elsewhere that need it more.

T60 is meant to be a specialised variant in use by airborne units, IIRC. Even so, it could simply be advanced enough (IE designed to go into a mass production cycle after 2077) that it never saw widespread use before the nukes, like the Vertibird chopper.

Adams AFB was known to have developed Eyebots (or worked on them), Hellfire armour and (presumably) some more other stuff like that, so it's not unfeasible the Brotherhood found the caches of these suits when salvaging Adams. But it is said to be designed by the US military. It was likely just never all that widespread before the war, with T51 and T45 making up the majority of the US forces.

Alternatively, it could have been a variant designed for US soldiers in the Gobi Campaign. Would make sense.

Sorry this was late, but interesting. So the T-60 was specifically design for Air drop combat. So it's kind of like the Space Marines in Warhammer, only in air.
