The Navy Pacific Missile Test Center PMTC requested that the U.S. Army Materials Technology Laboratory MTL perform a series of metallurgical tests on 16 components of the BSU-86B bomb fin assembly. The parts were characterized in accordance with applicable standards and contractual requirements as part of a First Article Inspection to confirm and verify specific fabrication operations performed by the manufacturer. The intent of the First Article Inspection is to certify the ability of the manufacturer to produce a component which satisfies the standards of quality and workmanship agreed upon by the U.S. Government and contractor. All components tested conformed to the established criteria for hardness and chemical composition. the bomb fins satisfied the minimum ultimate tensile strength UTS of 73,000 psi, as well as the intergranular corrosion test. Metallographic examination verified that the microstructure of all components reflected their corresponding heat treatment andor prior fabrication.
