20th century.
1930s.
The government of the Russian SFSR announced plans in 1931 to build a shipyard on the Amur at the modern site of Komsomolsk. Construction began in 1932. The town was mainly built using volunteer labor from the Communist youth organization Komsomol. This is how the town received the name Komsomolsk. However, the construction of the town was helped by the use of penal labour from the prison camps in the area. The suffix "on Amur" was added to differentiate from other towns with the same name.
1940s.
By the end of the 1940s, the shipyards plus facilities for other heavy industry had been completed. The city turned into a regional center for industries such as aircraft manufacturing, metallurgy, machinery, oil refining, and shipbuilding. Currently, Komsomolsk-on-Amur is the main center for the manufacture of Sukhoi military aircraft and the Sukhoi Superjet airliner. The MiG-15bis and the Lisunov Li-2 were both built in Komsomolsk-on-Amur.
