Military platforms often last for decades, long past the life spans of modern computing components and boards. System designers for these aging platforms must rely on a variety of solutions from lifetime buys of components when they go end of life to working with aftermarket suppliers, who buy obsolete product lines and keep producing them for customers with ultra long-term needs. In this podcast with Ethan Plotkin, CEO of GDCA, we discuss military aftermarket trends, open architectures, artificial intelligence, and how sustainment reform can help solve long-term obsolescence challenges get in defense applications.
