Self-Contained Underground Shelters for Pre-Positioned Deployment for Defense Against NBC Warfare [open pdf - 497KB]
Paraboloid fiberglass self-contained underground shelters can be pre-positioned in the field to allow personnel to operate in an NBC environment. These self-contained egg-shaped shelters are almost fully assembled and equipped with a life support system including an NBC detection system, air filtration systems, light, toilet, water tank, septic system, decontamination shower, food storage, and communications systems. Unlike conventional structures, this product is stealth, corrosion free, maintenance free, and provides radiation shielding and thermal protection. This document outlines four models that are available including a model for JIT (Just In Time) situations.
