T-51b power armor

T-51b Powered Infantry Armor or Power Armor was the peak of armored infantry technology before the Great War, developed in the West Tek Research Facility laboratories. At the end of the Anchorage Reclamation, the Armor had become standard issue for US Soldiers in Mechanized Regiments. Now, only the most technologically advanced factions with ties to pre-War military or government, such as the Brotherhood of Steel or the Enclave, have access to this type of 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 the 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 silver ablative coating can reflect laser and radiation emissions without damage to the composite subsurface. It usually has enough fuel to last a hundred years.

The Brotherhood of Steel does not possess the technology required to manufacture new Power Armor and relies only on pre-war suits. In the Enclave, this armor is seen as obsolete, as it was replaced by Advanced Power Armor and Advanced Power Armor Mk II, though it should be noted that it is still used by soldiers who have not been issued the newer armor most likely due to slow production rates.

History

 * 2065, August: The need for increased mobility in US Army Mechanized Cavalry units, leads the military research companies to focus their research to create a man based tank - the result is Power Armor.
 * 2065 - 2067: Power Armor research grows and several prototypes are developed, many of which prove to be unworkable in the field. These prototypes pave the way for future advances in military, construction, and fusion technology.
 * 2066, Summer: The first crude fusion cell is unveiled, one of the results of the Power Armor project.
 * 2067: The first suit of T-45d Power Armor is deployed in Alaska. While lacking the full mobility of future versions, this Power Armor is incredibly effective against Chinese tanks and infantry. Its ability to carry heavy ordinance becomes key in various localized conflicts, and it has the power to destroy entire towns without endangering the wearer. China rushes to create its own versions, but they are many years behind the United States.
 * 2074: Contrary to their claims of seeking only to retake Alaska from the Reds, American Power Armor units, infantry, and mechanized divisions are deployed to China, but they become bogged down on the mainland, putting a further drain on American resources and supply lines.
 * 2076, June: T-51b Power Armor prototype completed, resulting in the Power Armor that the player finds in Fallout 1. This is the pinnacle of Power Armor technology before the Great War. Many of these units are sent to China, and they begin to carve a swath through the Chinese forces. The Chinese resources are strained to the breaking point, and the supply lines from the nations China has annexed begin to break down.
 * 2077, January 22: The first domestic use of Power Armor within the United States for crowd and quarantine control. Units originally serving in China and the Anchorage Front Line find themselves fighting Americans at home. Food riots increase, and many civilians are killed. Several soldiers defect from the military both in Canada and the United States. They are captured, and are sent to military prisons.

Appearances in games
T-51b Power Armor and its hardened version appear in both Fallout and Fallout 2 (and was to appear in Van Buren), while the later also introduces Enclave's advanced variants. The armor also appears in Fallout 3, where the original T-51b is pretty unique, as the Brotherhood now uses a clunkier, makeshift version of Power Armor.

Fallout Tactics shows T-51b only once in the intro, and the Eastern Brotherhood Power Armor (called simply Power Armor there) is used instead in the game, including an advanced version, years before the Enclave's new model.

In Van Buren, the appearance of the armor was slightly changed. Here's how J.E. Sawyer justified the decision:


 * We tried to model the power armor as T-Ray did in the opening movie and game, but he could get away with clipping that would look really bad at close distances or certain angles. Simply put, building the Fallout power armor as it originally looked would have resulted in a suit with a tiny range of motion or a hilarious amount of clipping. We changed as much as we needed to allow for more flexibility in movement, but tried to stay very close to the original design whenever possible.

Locations
Description: ''A self-contained suit of advanced technology armor. Powered by a micro-fusion reactor, with enough fuel to last a hundred years.''
 * Fallout: Found at the Brotherhood of Steel Lost Hills bunker. Can be received by completing a quest or can be repaired using a guidebook and some tools.
 * Fallout 2: In a locker in the BOS bunker in San Francisco, Mariposa Military Base Level-2, sometimes in San Francisco stores

Fallout 3
The T-51b Power Armor is the Power Armor in the original games. It is a unique model in this game and can only be found via the dangerous Fort Constantine.

The T-51b is one of the only three Power Armor variants, the others being the Tesla Power Armor and the Enclave Hellfire Armor, in Fallout 3 which does not carry an inherent Agility penalty; instead, it grants a Charisma bonus for reasons unexplained (possibly a nod to the iconic nature of the armor in association with the Fallout franchise, or because it is hard to say no to someone wearing this impressive and powerful armor). For some reason it does not offer a Strength bonus like in previous Fallout games; this could be a mistake by the developers or a possible attempt to make no single dominant armor in the game.

Repair
The T-51b cannot be repaired using any other power armor variants, not even with the Winterized T-51b Power Armor from the add-on Operation: Anchorage. The T-51b can be broken down to repair T-45d Power Armor, destroying the T-51b. Shop keepers or caravan traders can repair T-51b Power Armor (a possibly expensive option) and the results are limited by the skill of the repairing NPC. NPCs can still repair it to a high enough condition to put it at a higher damage resistance than all other armors (with the exception of the Enclave Hellfire Power Armor from the Broken Steel DLC Pack).

On the plus side, T-51b armor is twice as durable as standard Power Armor, and thus it degrades half as quickly as it takes damage.

The only way to keep the T-51b from being damaged is to give it to followers, since their armor's condition never degrades.

Operation: Anchorage
See Winterized T-51b Power Armor. Oddly enough, the Winterized T-51b cannot be used to repair the old one. This is due to the fact that the version you get from the simulation is not the designated "Wasteland Variant". Instead you get the "Simulation Variant". It has almost ten million hp, designed to make it appear as though it is not degrading.

Bugs

 * In some cases the helmet can be found in the right corner of the room.
 * Followers may get stuck in Fort Constantine when you try to leave.(Confirmed on 360 and PC)
 * On the 360, PS3 and pc version the T-51b helmet picture shows it as a body armor not a helmet.
 * When dropped may fall through the floor in Megaton House. [other locations?][360 and PS3]
 * The armor also turns invisible if placed "on display" inside your Megaton House, or the Tenpenny Tower Suite. (Xbox 360 and PS3)
 * Sometimes, the helmet will be behind the shield. Grabbing it must be done from a reachable spot
 * Occasionally the armor will disappear or simply not be there when found in fort Constantine. The only remedy for this is to reload your last save. This is confirmed for 360 and for PS3/PC.
 * The T-51b helmet can in fact be anywhere inside the room where the armour is found. In one instance, for example, it was located behind the filing cabinets next to the table, requiring a jump up onto the table to reach it. Search the room thouroughly if you can not find it, or try to reload a previous save. (Confirmed for PS3)
 * Beware of "flying armour" when de-activating the shield protecting the T-51b power armour.
 * The armor may be seen vibrating or jumping around inside the containment field unprovoked.
 * After installing the Point Lookout add-on it occasionally happens that the armor, previously equipped to Star Paladin Cross, cannot be taken back from her through equimpent trade (is invisible while accessing her equipment). After restarting the game, the armor is once again available for taking back.
