The X-01 advanced powered infantry combat armor is designed for a single human operator, provided with the comfort and protection of a next-generation suit of armor. Work on the model was restarted by the Enclave in 2198, although it wasn't until 2215 that the research efforts began in earnest under Presidential mandate, with the first production model created in 2220. It represented a radical, new approach to designing powered armor, eschewing traditional armor design philosophies, but was never deployed in larger quantities until the 23rd century. The first test batch of the armor, designated X-01 Mk I, was developed for Presidential bodyguards, and served as the baseline for the remnants of the United States military, who developed it into a power armor tailored for the post-War wasteland. The development of the first suit of advanced power armor, designated X-01, began shortly before the Great War. The following section is transcluded from Advanced power armor.
