Electromagnetic Warfare Awareness Week
July 20-24, 2026
About
This summer, AOC will launch the inaugural Electromagnetic Warfare (EW) Awareness Week, taking place July 20-24, 2026. This annual observance is dedicated to increasing awareness and understanding of electromagnetic warfare and electromagnetic spectrum operations (EMSO), highlighting their enduring impact on military operations, national security, and technological innovation.
For more than a century, control of the electromagnetic spectrum has influenced the outcome of conflicts around the world. From the earliest examples of radio interference and electronic deception to today's sophisticated, multi-domain spectrum operations, EW remains a critical component of modern defense and security.
Throughout the week, AOC will share educational resources, historical insights, expert perspectives, and community-driven content that explore the evolution of EW and its relevance in today's increasingly contested electromagnetic environment.

EW Week Webinar
As part of the inaugural Electromagnetic Warfare Awareness Week, AOC is pleased to offer a special webinar exploring the history, evolution, and enduring importance of electromagnetic warfare.
Hear from a panel of distinguished experts as they examine the origins of electromagnetic warfare, its pivotal role in past and present conflicts, and its continued evolution in an increasingly contested electromagnetic environment. From early radar countermeasures and signal interception to today's sophisticated spectrum operations, attendees will gain valuable insight into how EW has shaped military strategy, enabled operational success, and become a critical component of modern defense.
Whether you are a seasoned EW professional, a student, or simply interested in learning more about this vital domain, this webinar offers a unique opportunity to deepen your understanding of the technologies, people, and events that have defined electromagnetic warfare throughout history – and continue to influence its future.
In recognition of EW Week, this webinar is being offered free of charge to the entire community as part of AOC's commitment to advancing awareness, fostering dialogue, and inspiring the next generation of EMSO professionals.
A Century and a Half of EW
Historical Timeline of Electromagnetic Warfare
Explore the milestones, innovations, and operations that have shaped the electromagnetic battlespace. AOC's interactive EW timeline traces the development of electromagnetic warfare from its earliest origins to the advanced EMSO capabilities employed around the world today.
From James Clerk Maxwell's theoretical groundwork in 1864 to the signal-contested battlespaces of today, the electromagnetic spectrum has shaped the outcome of every major conflict of the modern era. Explore our comprehensive timeline tracing the discovery of electromagnetic waves, the birth of radar, the evolution of electromagnetic warfare across two world wars and beyond, and the ever-expanding role of spectrum operations in an increasingly connected world. Woven throughout is the story of AOC itself, reflecting the association's deep roots in, and enduring commitment to, the EW community.
