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


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 their 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 armor is fitted with a back-mounted TX-28 MicroFusion Pack which generates an output power of 60,000 Watts to power the HiFlo hydraulic systems built into the frame of the suit. Made of a poly-laminate composite, the shell of the T-51b is lightweight and capable of absorbing over 2,500 Joules of kinetic impact. The 10-micron-thick silver ablative coating can reflect laser and other radiation emissions without damage to the composite subsurface, and the eyeslit for the helmet is made of bulletproof glass to protect the wearer from any projectiles.[1] It also includes a recycling system that can convert human waste into drinkable water, enhancing survival.[2] The armor is completely sealed and offers excellent protection from radiation.




  • 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.


  • 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]


  1. 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?"
    (Ricky's dialogue)
  2. The Chosen One: "{459}{}{Heh-heh. Actually, I just urinate in the armor, and it recycles everything. Isn't that interesting? Do you know what 'recycling' means, little one?}"
    Wright child: "{476}{}{Yes! Recycling means you drink pee!}"
