This report describes an NSPO sponsored task to evaluate the safety and structural reliability of TRIDENT-C4 missile handling equipment. In a first phase, drafts of new design specifications were examined in view of current government and industry criteria for similar service. In this second phase, design stress allowables as well as a proof loading test policy for verification of structural integrity were assessed by study and experimental programs. Structural elements of mild steel and aluminum alloy weldments and of steel wire rope are taken to typify this service. Potential sources of initial and/or use-related failure include welding defects, cold cracking, lamellar tearing, fatigue, and salt.
