Yttrium barium copper oxide is a class of materials that exhibit superconductivity at (relative) high temperatures. This has a lot of applications and some of them are defense-related.

Besides the applications in superconductors, it's also used in allows to strengthen, and is used in the creation of certain ceramics and glasses.

Yttrium is used to make high performance filters and oscillators. YIG filters and oscillators are wide band high Q microwave devices used in high performance instruments, radar and frequency agile communication systems. An example would be the AN/ALQ-161A B1-B countermeasure system.
