Recurrence pattern: every year on November 30.

Radio-Technical Troops Day is observed in Ukraine every November 30, celebrating the service members and veterans of the country's radio-technical troops within the Armed Forces. This professional holiday recognizes the critical role these troops play in providing radio-technical reconnaissance of air, land, and sea space, identifying airborne targets, and assisting air defense forces. Established in 2010, the day has gained heightened significance since the onset of the Russian invasion, as these troops have been vital in detecting and neutralizing aerial threats to protect military and civilian infrastructure. The Radio-Technical Troops were formed in 1992, shortly after Ukraine's independence, and have undergone modernization to enhance their capabilities against electronic warfare. Their efforts have contributed to the destruction of numerous enemy aircraft and missiles since the full-scale invasion began.
