Cost Estimate for Gun Liner Emplacement

Abstract : Recent firing success of an explosively-bonded tantalum alloy gun liner has prompted an examination of other gun liner emplacement techniques. One of them is Gun Liner Emplacement with an Elastomeric Material (GLEEM). Costs for this approach are compared to those of explosive bonding, and on a qualitative basis GLLEM is found to be less expensive. The absolute costs to use GLEEM will depend primarily on the cost of the liner and machining the rifling in the barrel. Different materials and manufacturing technologies are suggested to reduce these costs.
