This paper model is the T-51B Power Armor (T-51b Powered Infantry Armor, or Power Armor), represented the peak of armored infantry technology before the Great War, developed in the laboratories of the West Tek Research Facility, from the game Fallout, the papercraft was created by PepMaster.
At the end of the Anchorage Reclamation in January 2077, the armor had become standard issue for American soldiers in the Army's Mechanized Cavalry Regiments. Now, only the most technologically advanced factions with ties to the pre-Great War American military or federal government, such as the Brotherhood of Steel or the Enclave, have access to this type of power 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 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 damaging 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 ten thousand years.
T-51b power armor and its hardened version appear in both Fallout and Fallout 2, while the latter also introduced the Enclave's advanced variants. The armor also appears in Fallout 3, where the original T-51b is unique, as the local chapter of the Brotherhood of Steel mostly wear the first sucessfull model of power armor; the T-45d. A winterized combat version is used by American troops in Operation: Anchorage.
As shown in both Fallout and Fallout 2, T-51b models seem to exist in greater abundance along the West Coast and in the Core Region region compared to their availability in the Capital Wasteland. Even in the Pentagon, ostensibly the heart of American military power, most if not all power armor suits were of the T-45d line. While this discrepancy is unexplained, speculation suggests that T-51b units were in higher concentration in the west, possibly due to its proximity to the Chinese battlefront.
Fallout Tactics shows the T-51b power armor only once in the introduction to the game, and the Eastern Brotherhood power armor is used instead in the game, including an advanced version, years before the development of 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.
The T-51b appears in greater numbers in Fallout: New Vegas, appearing on Brotherhood of Steel patrols and sometimes appears mixed with T-45d power helmets due to a bug.
The Brotherhood of Steel does not possess the technology required to manufacture new suits of power armor and relies only on repaired and refurbished pre-Great War suits. Among the soldiers of the Enclave, this power armor is seen as obsolete, as it was replaced by the Enclave's advanced power armor and advanced power armor Mk II models, though it should be noted that it is still used by soldiers of the Enclave who have not been issued the newer armor, most likely due to slow production rates for a faction that is still quite small and possess only limited resources in the post-atomic world.
