An overview of the Department of Defense research and development acti
vities in superconductivity is presented. Efforts exist in the Navy, A
ir Force, ARPA, BMDO and NSA. Highlights of activities in each of thes
e organizations will be discussed. In general, the DOD efforts in supe
rconductivity are in the electronics areas with major programs in spac
e applications, digital electronics, millimeter, microwave and tera-he
rtz applications, antenna, and sensors (magnetic, i.r., high frequency
). Significant efforts also. exist in power applications as they speci
fically relate to ship propulsion and aircraft power generation.
