Lecture: ‘The Story of Electro-Magnetic Spectrum Operations in delivering Air Capability’

Defence and security operations across history have been associated with the physical domains of Land, Sea and Air. Space has become the most recent, and highly-publicised, addition to this. Operational success in these domains is increasingly dependent on the quality of information available to participants in operations. The electro-magnetic spectrum (EMS) is the main medium by which such information is collected and disseminated. The invention of radios in the late 19th century was followed by widespread adoption for communication. Within 50 years, the use of radar to detect vehicles and control weapons had made a significant impact on the success or failure of military operations. In more recent times, infra-red and laser systems have become key elements in a range of defence and security applications.

Consequently, the EMS has become a domain in which participants in operations must maintain their own ability to use it, while - on occasions - denying or controlling their opponents use of it. There are many ways in which participants can conduct EMS Operations (EMSO), which are often grouped into 3 broad areas: Electronic Surveillance, Electronic Defence and Electronic Attack, collectively known as Electromagnetic Warfare (EW). The development of the equipment involved in these activities over the period 1900 to the present day provides insights into the innovations made to support past air operations and indicates some of the issues facing the development of air capability for the future.

The lecture will tell the story of EMSO and EW through:
