A FAULT-TREE BASED ANALYSIS WILL BE MADE TO IDENTIFY INHERENT VULNERABILITIES OF A HARD SILO BASED BALLISTIC MISSILE.

A FAULT-TREE BASED ANALYSIS WILL BE MADE TO IDENTIFY INHERENT VULNERABILITIES OF A HARD SILO BASED BALLISTIC MISSILE. THESE VULNERABILITIES, IN FUNCTIONAL OR FAILURE MODE TERMS, WILL BE COMBINED WITH CONSTRUCTION ANALYSES OF SILO DESIGNS TO DETERMINE TARGET DAMAGE MODES, AND EFFECTS. A SERIES OF CONCEPTUAL NON-NUCLEAR KILL (NNK) MECHANISMS WILL BE EVALUATED, IN ORDER TO ESTABLISH THREAT INTENSITY LEVELS NECESSARY TO SECURE THE DAMAGE MODES PREVIOUSLY IDENTIFIED. ENGINEERING ESTIMATES AND INFORMED TECHNICAL OPINION WILL FORM THE BASIS OF FEASIBILITY ESTIMATES FOR MATURING THREAT TECHNOLOGY TO THE REQUIRED LEVEL BY THE 1990-2010 TIME FRAME. A FINAL REPORT DETAILS THE CURRENT AND PROJECTED POTENTIAL VULNERABILITIES, RECOMMENDS COUNTERMEASURES OR DESIGN CHANGES, AND OUTLINES ADDITIONAL RESEARCH NEEDS.
