The regiment was deployed to the Southern Front in May 1942 it received the Guards designation and was reorganized into the 46th Guards Night Bomber Regiment.

Later life
After the war Ryabova was sent by the regiment commander to attend the Russian Air Force Academy with Mariya Smirnova, but they were not admitted because the academy was officially closed to women. After being rejected from the Air Force Academy, she returned to her studies at Moscow State University, where she remained socially active after graduating in 1948 from the Faculty of Mechanics and Mathematics before defending her thesis and earning her Ph.D. in 1951. After graduating she worked as a teacher at the Moscow Polygraphic Institute, and from 1963 to 1972 she worked as an Associate Professor of the Department of Theoretical Mechanics at the Dzerzhinsky Military Engineering Academy. During her life she traveled to Italy, France, Korea, and Bulgaria. Due to a head injury she suffered in the war she experienced severe headaches often but tried to hide them, only to end up fainting when greeting an Italian delegation. In June 1945 she married twice Hero of the Soviet Union Grigory Sivkov, whom she had met during the war. She gave birth to her first daughter Natalya in 1947 and her second daughter Irina in 1952. She died on 12 September 1974 when she was only 53 years old.
