Project Adamantine

Project Adamantine was a pre-War Grafton Steel Research and Development project at Grafton Steel Underground to produce a new steel alloy for the United States Armed Forces.[1]


One of the three projects undertaken by Grafton Steel, the goal of Project Adamantine was to create a form of "super steel", in order to comply with the federal grant's agreement of developing steel products specifically for the military sector.[2] Although concerns were made of the feasibility of the project, pointing out the various other metal alloys stronger than steel, the project was left in an uncertain state.


Project Adamantine is mentioned only in Fallout 76, introduced in the Wastelanders update.
