2025/11/21 (Fri.) Air Defense Day

 

On November 21, in 1934, our country held its first large-scale air defense exercise in Nanjing. Since then, air defense has gradually become more important in various places. In 1930, the National Government, in order to promote air defense construction and commemorate it forever, specially decreed that November 21 of each year is "Air Defense Day".
