German Quarter
TsAGI (the Central Aerohydrodynamic Institute), established in 1918 in the former German Quarter, () became a seed for one of two aircraft-industry clusters in Moscow. An aircraft-engine plant (the present-day NPO Salyut) was established on the opposite bank in 1926. Andrey Tupolev's design firm moved out of TsAGI into his own premises on the Yauza () in 1936; by 1945, the Tupolev staff reached 5,226. The postwar period added the Mil Moscow Helicopter Plant in Sokolniki and the Lyulka rocket-design bureau (now NPO Saturn) in Babushkinsky District.
