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 was deployed to China in 2074 alongside American infantry and mechanized divisions. This wave of power armor utilization was not effective, became bogged down on the mainland, and served as a net drain on the war effort.

In 2076, a new prototype was developed and sent to bolster existing efforts. Although the power armor lacked built in weapons, these variants provided the benefit of being able to carry ordinance otherwise too heavy for infantrymen. This iteration found success, pushed through enemy forces and broke down supply lines. 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, would later go on to design the Excavator power armor for the Garrahan Mining Company.

Its first deployments to Alaska occurred in 2067 to counter Chinese tanks and infantry during the Battle of Anchorage. The armor units were effective in this environment as well, contributed to victory in Alaska. The same units that served in China and then Alaska were then used for crowd and quarantine control domestically. At the beginning of 2077, the power armored soldiers fought Americans at home as food riots increased, which resulted in many civilian deaths and subsequent soldier defections.

Following the Great War, many suits are still found throughout the wastelands, providing those who wear it substantial protection from threats. The armor is utilized by the Brotherhood of Steel, including the Lyons' Brotherhood of Steel and the loyalist Outcasts.

T-45a model


An early version of the standardized T-45d, the T-45a model is similar in design to its successors. It offers less performance and protection than later models. In Fallout 4, the T-45a model is rusted and deteriorating.

T-45d model


Several variations of the basic model, including the Lyons' Pride power armor, Brotherhood T-45d power armor, and Army power armor.

MP-47/A prototype medic power armor


An upgrade of the standard T-45d power armor, using a revised T-47 model. The MP upgrade included an automated delivery system for various medical substances such as stimpaks.

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 an 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.
