T-45 Power Armor

T-45 Power Armor is a Power Armor model in Fallout 3, Fallout: New Vegas, Fallout 4, and Fallout 76.

Background
The T-45 series of power armor was built by defense contractor West-Tek and served as the first power armor variant ever utilized by the U.S. military on the battlefield. The power armor prototypes were slated to be part of an exhibit at the Museum of Technology in 2078. Harold Frost, one of T-45's original designers, designed the Excavator power armor for the Garrahan Mining Company. Following the Great War, many suits are still found throughout the wastelands, providing those who wear them additional protection from threats. Stripping out the joint servos removes the need for special training. 

T-45d model


Several variations of the basic model, including the Lyons' Pride Power Armor and Brotherhood T-45d Power Armor.

Outcast model


Modified by the Brotherhood Outcasts, the armor has been painted red and black and Outcast symbols have been added. Outcast recon armor is worn independently or as part of a full Power Armor set. Linden's Outcast Power Armor is a unique variant.

Tribal Power Armor


Unique variant of the standard T-45d found in the Pitt, one set is worn by Ishmael Ashur and another is a prized possession of Everett.

NCR Salvaged Power Armor


NCR Salvaged Power Armor is T-45d Power Armor recovered by the NCR during their war with the Brotherhood of Steel. NCR technicians stripped out the joint servos, making it more difficult to use, but has no special training requirement. It has a yellow NCR bear logo painted on the chest plate and red stripes on the arms.

Scorched Sierra Power Armor


The scorched Sierra Power Armor is a suit of T-45d Power Armor that has been modified with a NCR theme, worn by Colonel Royez.

Behind the scenes

 * T-45d Power Armor is also mentioned in the Van Buren tech demo by Corporal Armstrong.
 * The Art of Fallout 3 states that the armor was created as a 3D model from scratch, in order to capture the mood of the game being developed.
