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


T-45d power armor overview.png

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.[1][2] The power armor was deployed to China in 2074 alongside American infantry and mechanized divisions.[Non-canon 1] 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.[Non-canon 1]

In 2076, a new prototype was developed and sent to bolster existing efforts.[Non-canon 2] Although the power armor lacked built in weapons, these variants provided the benefit of being able to carry ordinance otherwise too heavy for infantrymen.[Non-canon 3][Non-canon 4] This iteration found success, pushed through enemy forces and broke down supply lines.[Non-canon 2] The power armor prototypes were slated to be part of an exhibit at the Museum of Technology in 2078.[3] Harold Frost, one of T-45's original designers, would later go on to design the Excavator power armor for the Garrahan Mining Company.[4]

Its first deployments to Alaska occurred in 2067 to counter Chinese tanks and infantry during the Battle of Anchorage.[Non-canon 3] The armor units were effective in this environment as well, contributed to victory in Alaska.[Non-canon 5] The same units that served in China and then Alaska were then used for crowd and quarantine control domestically.[Non-canon 5] 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.[Non-canon 5]

Following the Great War, many suits are still found throughout the wastelands, providing those who wear it substantial protection from threats.[2] The armor is utilized by the Brotherhood of Steel, including the Lyons' Brotherhood of Steel and the loyalist Outcasts.

Behind the scenes



  1. Fallout 76 loading screens: "Built by defense contractor West-Tek, the T-45 series of Power armor was the first to be successfully deployed on the battlefield. Its introduction changed the nature of modern warfare."
  2. 2.0 2.1 Fallout 4 loading screens: "The T-45 series was the first version of Power Armor ever employed on the battlefield by the U.S. military. Many suits remain active in the Wasteland today, and provide their wearers with substantial protection."

  6. Lone Wanderer: "You got anything for me?"
    Everett: "Well, I'll be damned. That makes 100 ingots you found. And here I remember thinking you'd be lucky to bring back any at all. Ain't no question, you earned the treasure of my collection. This armor goes all the way back to when the Brotherhood tried to wipe out The Pitt. Some of the tribals who worshipped Ashur made it to look like their god. Try it on, and you'll feel a little like a god, yourself!"
    (Everett's dialogue)
  7. 7.0 7.1 Courier: "Tell me about the heavy troopers."
    Hanlon: "They have the best equipment the NCR can get its hands on, power armor salvaged from our war with the Brotherhood. Techs strip out the joint servos so you don't need special training to wear it. It feels like you're carrying a Brahmin on your back, but it can take a heck of a lot of punishment."
    (Hanlon's dialogue)


  1. 1.0 1.1 Fallout Bible 0: 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.
  2. 2.0 2.1 2076 June Power Armor prototype completed, resulting in the Power Armor players find 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.
  3. 3.0 3.1 Fallout Bible 0: 2067 The first suit of 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.
  4. Fallout Bible 0: 2065 August Increasing need for mobility in the United States mechanized cavalry leads the military to focus the efforts on creating a man-based tank - essentially, a two-legged walking armored unit: 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 Adding further insult to the Chinese-American relations, the first crude fusion cell is unveiled, one of the results of the Power Armor project. Devices designed for the fusion cell begin to be manufactured. Incorporating fusion power into the general US infrastructure begins, but the process is too slow to supply power to the regions that need it. Nearly eleven years later, few sections of the United States were supplied with fusion power.
  5. 5.0 5.1 5.2 Fallout Bible 0: 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.
  6. Fallout Shelter T-45a power armor item description: "Before Power Armor even really existed, this baby was born."
  7. The Prisoner: "{c16711680}Do you know how to use all that gear or is it just for show?"
    Armstrong: "{c255}I am trained in the use of light and heavy assault weapons and have fifty three hours of field experience in the T-45d Power Armor, citizen. Most of those were during the Anchorage Reclamation."
    Armstrong: "{c255}Well, here's the entrance to the vault, citizen. I have to head back to the City now. This T-45d eats up small energy cells like Chans at a rice buffet! Ha, ha, ha! Don't worry, though. We'll send those godless reds packing within the month!"
    The Prisoner: "{c16711680}Thanks, Corporal Armstrong! Goodbye."
    (Armstrong dialogue file)
  8. The Art of Fallout 3, p. 17: "The Brotherhood of Steel power armor was the first costume to be designed, and it was done entirely in 3D, skipping the concept art stage. This was an important piece to get right, as it had to feel true to the original, yet freshened and updated for this game's unique aesthetic."
