Solutions that power and protect

Military readiness depends on systems that can respond anywhere and any time with speed, precision and resilience. Our specialty materials play a key role in supporting this effort — in jet engines; structures for land vehicles; systems for ships; and sophisticated armor that protects systems and people when they’re in harm’s way.
