Abstract: It is proposed to construct a low cost simulated ballistic missile for training purposes or as a military decoy. The invention contemplates the use of standard I-beams, reinforced pipe, and cement filler to provided missile stages that duplicate the weight and overall dimensions of the actual missile stages. The beams are welded into a columnar cross-sectional shape sized to fit into the reinforced pipe. Principal advantage of the invention is the achievement of a structurally strong simulated missile at relatively low manufacturing cost.
