The Refurbishment, Re-Engineering, and Testing for Sustainable Re-Introduction of Components into Legacy Systems – Phase II

NCMS Project #: 140975

Problem: When a product is deemed unreliable, or doesn’t serve the intended need, it is often scrapped. That process is an undesirable, but realistic outcome. But with today’s focus on reuse, recycle, and sustainment, the option to re-engineer and refurbish is an economically sound one. MK 122 Mod 0 warheads were removed from service and entered into the demilitarization program for destruction. Re-engineering the MK 122 Mod 0 makes a perfect test case for the effort of recycling and reusing throughout the DoD.

Benefit: While the process of recycle and reuse in industry is not new, the category of parts that are refurbished is limited, generally to low risk, non-complex components. This project could open the door to U.S. industries evaluating parts to reuse not formerly considered. Once piloted and evaluated, the project results could be used in components for newer aircraft, ground vehicles, naval vessels, and numerous other critical and tactical equipment.

Solution/Approach: Phase I was successful in identifying a path to production of MK122 warhead case and liner. The primary areas of the Phase II investigation will be in relation to the inspection and process requirements of the raw material and forming processes. Technology advancements since initial production have occurred and comparative analysis needs to occur. Phase II is critical to conduct investigations into the new technologies and determine the impact on the performance of the warhead. Additionally, evaluation of specific design elements and safety considerations from legacy equipment into newer equipment will be made, noting exceptions to drawing and specifications to accommodate the industrial base’s capability with will require the same comparative analysis.
