High-temperature superconducting (HTS) cable is nearing full-scale integration — already demonstrated in the commercial electric grid and successfully tested by the Navy (a working HTS degaussing system on a modern U.S. destroyer in 2008), with electric-ship propulsion and high-energy weapons like rail guns and lasers as the next targets; patent-trend analysis projects continued innovation.
