Electronic Warfare Specialists Day is observed in Ukraine every September 12, dedicated to the military specialists who play a crucial role in modern military operations. The day highlights the importance of electronic warfare (EW), which involves using the electromagnetic spectrum to control or disrupt enemy operations. The origins of electronic warfare date back over a century, with notable early uses during the Second Boer War and World War II. Electronic Warfare Specialists Day was first established in the Armed Forces of Ukraine in 2006, but it was temporarily canceled in 2012. The celebration was reinstated in 2021, reflecting the growing significance of electronic warfare units, especially following Russia's full-scale invasion of Ukraine in 2024. Today, mobile EW teams are essential for countering threats such as drones, underscoring the critical nature of EW in contemporary military strategies.
