Катю́ша (Katyusha) is a Russian wartime song composed in 1938 by Matvei Blanter with lyrics from Mikhail Isakovsky. Written just before World War II, the song quickly became popular throughout the USSR. Its first official performance was by Valentina Batishcheva in the Column Hall of Moscow's House of the Unions. Later it was performed by the Red Army Choir and other singers.
In Girls und Panzer, this song is used for Pravda Girls High School.
- The song is the source of the nickname of the BM-8, BM-13, and BM-31 "Katyusha" rocket launchers that were used by the Red Army in World War II.
- The most famous version of the song was performed by the Red Army Choir.
- On the Red Army choir's first recording of the song (1941), the song was sung lively and some of the lines weren't repeated while their second recording (1970s), the song was slightly slower and reveals some sorrowing feeling.
- Due to copyright issues, the English Dub of Girls und Panzer omits the song completely and instead, replaces the song with another Russian folk song, Korobeiniki (Song).
- The song is like a Russian equivalent of Erika which talk about a woman waiting for her beloved one to come back from the war.
