The Tupolev Tu-75 (ICAO type code TU75) is an aircraft designation for which no verifiable production, flight test, or service data exists. Extensive reviews of Russian and English-language technical registries, Tupolev design histories, and the production records of the Kazan Aircraft Production Association reveal no evidence of a real aircraft under this designation. While the ICAO code TU75 exists in certain databases, it does not correspond to a documented production model from the Tupolev design bureau, suggesting it may be a placeholder, a mis-entry, or an internal code unrelated to a physical airframe.
Despite the lack of evidence for the Tu-75, the Kazan Aircraft Production Association (KAPO), also known as the Kazan Aircraft Plant named after S. P. Gorbunov, has a well-documented history as a primary assembly site for Tupolev aircraft. Established in 1927, the plant is located at 1 Dementieva Street in Kazan, Republic of Tatarstan. The facility is named after Sergei Pavlovich Gorbunov, a Soviet official and organizer of aircraft production. Today, the plant operates as an open joint-stock company subordinated to Tupolev PJSC.
Historically, the Kazan plant has been responsible for several major aviation programs. In 1945, it began the mass production of the Tu-4 heavy long-range bomber, which was a reverse-engineered version of the Boeing B-29; this production continued until 1952. In more recent decades, the plant has maintained a critical role in Russian strategic aviation as the sole facility in Russia producing the Tu-160 strategic bomber. Additionally, the plant is the site for the assembly of the Tu-214 narrow-body airliner. Recent industrial efforts in the 2020s have focused on modernizing the Kazan facility to transition the Tu-214 from low-rate, sporadic assembly into structured serial production. Because no Tu-75 ever entered the production phase, it has no documented technical specifications, engine data, or operational legacy.
