This armor is identical in appearance to the recon armor available in Fallout 3, though with a much higher value.

Unlike the under armor for the T-51b power armor models, this one is also designed to offer limited protection from anti-personnel weapons. Its purpose is twofold: it allows the user to actually operate the armor and protect soft tissue from moving parts inside the suit and heat. Attached to it is the interface and mounts for the T-45d power armor. Intended to serve as the under-armor of the T-45d power armor, the recon armor is a vacuum-sealed asbestos jumpsuit covering the entire body.
