The T-51b power armor is a type of armor in Fallout: New Vegas.


A pre-War product of West Tek in conjunction with the United States government, T-51 power armor is made of a poly-laminate composite, shielding the user from radiation and damage while providing increased strength.[1][2]


The Mojave variant of the T-51b is a type of powered infantry armor. In order to wear the armor, one must first acquire Power Armor Training, which can be obtained by completing the quest Still in the Dark and then completing Eyesight to the Blind or Tend to Your Business, or by completing the For Auld Lang Syne quest. The armor is relatively rare in the Mojave Wasteland, as the Brotherhood of Steel, the only faction which regularly uses power armor has its own faction-specific version of the armor. The Brotherhood-specific variant is not as rusted as the regular variant, due to the Brotherhood's high maintenance of weapons and armor.




  • The T-51b power armor is different from the Brotherhood T-51b power armor because the chest, shoulder, and calf armor pieces, as well as a few other parts, are green instead of gray. This is similar to the differences between Fallout 3's version of the T-51b power armor and the winterized T-51b power armor.
  • When wearing this armor, back-sheathed weapons will be holstered differently than if the player character was not wearing this armor. For example, without power armor, the player character holsters the hunting shotgun with the butt of the gun behind their right shoulder. With the armor on, the butt of the gun will now be behind their right hip.
  • T-51b power armor, with 2,000 item HP, is the most durable armor in the base game.
  • Unlike the T-51b power armor in Fallout 3, this version gives a Strength bonus.
  • The Courier states that the T-series' vision slits are bulletproof.[3]


  • Icon pc.png Icon ps3.png Icon xbox360.png When using large weapons like miniguns, the armor's hip will become see-through, and the player character will appear hipless. [verified]
  • Icon pc.png If spawning the armor portion of this set from the console, and if the player character is currently wearing it as well, the armor will not show up in their inventory. It will apply the weight associated with carrying the armor, however. This seems to be due to the fact that although you cannot view nor interact with the item it is indeed in your inventory. If one drops the set that they are currently wearing, the newly spawned armor will appear in their inventory. [verified]

  3. The Courier: "You're saying that you killed a Brotherhood of Steel Paladin?"
    Ricky: "What's it sound like I'm saying? If I was saying what you said I was saying, then yeah, I said it!"
    The Courier: "Please go on. This promises to be entertaining."
    Ricky: "I was walking along, minding my own, and up pops one of them Brotherhoods. He yells "Hand over that laser rifle, asshole!" So I hand it over, just to make him think I'm scared! But really I'm not! I never am! Before he knows what hit him, I draw my 11mm machinegun and BAM! BAM! Right through the eyeslit in his helmet! D.O.A.!"
    The Courier: "What a load of crap. The eyeslits of T-series power armor are bullet-proof!"
    Ricky: "Then I guess this dumb fucker's armor musta been... D-series or something! All I know is, he died up real dead when I killed him, okay?"
