The original prototypes survived to 2077 and were slated to become literal museum pieces at the Museum of Technology on the National Mall in 2078. This temporary solution would eventually become the mainstay of American power armor units, especially as subsequent upgrades reduced the impact of the mobility problems that plagued the early production runs. The speed at which it had to be deployed, less than two years after the development of power armor began at West Tek, resulted in the creation of a stop-gap model utilizing existing technologies and manufacturing techniques. The T-45 powered combat infantry armor was the first design pressed into service in the Sino-American War, with its first deployments taking place on the Alaskan Front to counter the Chinese offensive.
