Abstract: Military organisations must ensure that electronic warfare (EW) systems used by front-line units are correctly programmed with up-to-date electronic warfare information. To accomplish this vital task, an Electronic Warfare Operational Support Centre (EWOSC) facility is an essential requirement to facilitate the minute-to-minute management and dissemination of the relevant electronic warfare data in support of operational commands. This short paper introduces the concept of a traditional Electronic Warfare Operational Support Centre and describes the design of databases to support such an organisation.
