The Day of Radio-Electronic Fight Troops is observed in Russia every April 15. This professional holiday celebrates specialists involved in the country's radio-electronic defense, acknowledging their significant contributions to military operations. Established by Presidential Decree in 2006, the date was chosen to commemorate a historic event from the Russo-Japanese War in 1904, when Russian battleship Pobeda successfully disrupted Japanese communications during a naval attack on Port Arthur. On this day, Russian experts in radio-electronic warfare receive congratulations and gratitude for their valuable work. The holiday highlights the importance of radio-electronic warfare, which has been integral to military operations since the advent of radio technology.
