T-51b Power Armor (Fallout: New Vegas)

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

Characteristics
The Mojave variant of the T-51b is a type of powered infantry armor, almost exclusively used by the Brotherhood of Steel. In order to wear the armor, the player 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 For Auld Lang Syne. The T-51b power helmet is somewhat rarer than the actual armor, as most of the dead soldiers it is worn by wear the T-45d power helmet.

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 outer shell of the T-51b is lightweight and capable of absorbing over 2500 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 bullet proof glass to protect the wearer from any projectiles. The armor usually carries enough fuel to last for about a thousand years.

Locations

 * One can be purchased at the armory in Hidden Valley bunker from Knight Torres, the Brotherhood quartermaster, along with helmets and T-45d power armor for replacement parts (after completing Still in the Dark and Eyesight to the Blind or Tend to Your Business).
 * Another T-51b power armor and a helmet (the helmets found with Brotherhood and non-Brotherhood sets are exactly the same) can be found in the Deathclaw Promontory on a dead prospector (presumably ex-Enclave soldier since they too wear the T-51b power armor as seen in the Enclave Oil Rig) soldier who is laying next to a dead prospector (presumably ex- Enclave soldier) wearing a set of Remnants power armor.
 * Another non-faction related T-51b can be found at Brotherhood of Steel Safehouse after downloading patch 1.02 on PS3 and Xbox 360 or 1.20 on PC.
 * Pre-patch, One is obtained after joining the Brotherhood of Steel. Post-patch, a set of T-45d power armor is given.

Bugs

 * When you sit down the shoulder pads will rotate and clip inside the body. The same glitch also occurs with the T-45d. It will only occur if the player sits on a chair. Sitting on a sofa will not make the shoulder pads clip through the armor, although sometimes this will be reversed.
 * When using large weapons like miniguns, the armor's hip will become see-through, and the player will appear hipless.
 * If spawning the armor portion of this set from the console, and if the PC is currently wearing it as well, the armor will not show up in 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. It was found that if you drop the set you are currently wearing, the newly spawned armor will appear in your inventory.
 * An infinite supply of the non-faction related T-51b from the Brotherhood of Steel Safehouse can be obtained by removing all patches and downloading them again. This will make the armor spawn in the Safehouse again. This glitch can be done repeatedly until a large quantity of armor is acquired.
 * This armor seems to mesh with some rifle-gripped weapons (eg. Sniper rifle (Fallout: New Vegas) and Assault carbine).
 * If you give the armor to a companion to wear, and the response is "This follower will not wear this faction's armor", the armor might disappear. The only way to resolve this is reload a save.
