This armor is the result of a post-War research and development project undertaken by the Enclave. An early iteration was completed by October 2080, and was shipped to Vault 51 at the behest of the vault's ZAX computer while the final mass-produced version would see large scale deployment in 2278. Initially, the mass-produced armor was one of several concurrently active research projects taking place at the Adams Air Force Base, including one on eyebots and a material called Duraframe, but ultimately came to be the most in-demand project fully completed; other projects, much to the chagrin of researchers such as Whitley, were canceled in favor of the new model of power armor by Colonel Augustus Autumn.

As state-of-the-art power armor, it is conclusively the best and most advanced model of power armor there is. It provides its wearers with more protection than any other form of armor produced post-War, due to its unique Duraframe components and high resistance to heat
