Abstract

The Naval Research Laboratory (NRL) is exploring the feasibility of deploying high temperature superconducting electrical and electronic devices and components in military systems, especially in space. The initial High Temperature Superconductivity Space Experiment (HTSSE-I) will demonstrate that High Temperature Superconducting (HTS) technology is sufficiently robust to survive the space environment and that it has the potential to significantly improved military systems. The devices for this mission have been procured, tested, space qualified and integrated into a space package which was shipped from NRL for on-orbit mission which is scheduled for 1993. The second HTSSE program began in 1991 when contracts were awarded for the procurement of a variety of advanced devices and subsystems based on HTS technology. Two versions of each component in space qualified packages will be delivered to NRL for electrical verification, space qualification, and integration with cryogenic refrigerators and the necessary ambient temperature electronics into a payload which will be in orbit late in 1996. This paper will describe the properties of superconductivity which may impact communications and surveillance systems and describe how HTS can be employed beneficially in operational electronic systems.
