T-51 Power Armor

T-51 power armor is a type of armor appearing throughout the Fallout series.

Background
A pre-War product of West Tek in conjunction with the United States government, T-51 power was created using a poly-laminate composite. Features include a back-mounted TX-28 MicroFusion Pack, HiFlo hydraulic system, and the shell is capable of absorbing over 2500 Joules of kinetic impact. The power armor's coating is comprised of 10 micron silver, serving to reflect laser and radiation emissions without damage to the composite subsurface.

Described as the "pinnacle of mechanized protection before the Great War," the armor was developed at Fort Strong, utilized in both China and at the Battle of Anchorage. Suits sent to Anchorage required additional effort to adapt to the cold climate.

Those who utilize the armor benefit have the ability to survive for weeks without water, and protection from radiation damage if the suit remains airtight. Some suits could undergo a special chemical hardening process.
