In 1924, Pavel Sukhoi joined the Central Aero and Hydrodynamic Institute, or TsAGI, collaborating in the design of the ANT-25. Design teams headed by P O Sukhoi and A A Arkhangelski but under Tupolev's general direction, were responsible before the second World War for a series of high- speed and long-range bombers, including the ANT-25 (RD).
