The armor's development was not completed until 2277, at the Enclave's facility at Adams AFB, after reallocating resources from other projects into the Hellfire project. Further development of the armor was halted due to the Whitespring facility losing communication with the other Enclave facilities and the eradication of all Enclave personnel within the Whitespring facility. In October 2080, one of the prototype suits was sent to Vault 51 at the order of ZAX 1.3c, impersonating Stanislaus Braun through his writing style. A prototype version was developed shortly after the Great War by the Enclave stationed at The Whitespring Bunker. The most advanced power armor variant in the wasteland is the Hellfire powered combat infantry armor, developed based on regular power armor designs.
