Tupolev TB-6 (internal designation ANT-26; Russian: Туполев ТБ-6/АНТ-26) was a proposal for a 1930s heavy bomber that did not advance beyond blueprints. Inspired by the success of ANT-20/PS-124, Tupolev in 1929 began work on an even larger aircraft powered by 12 engines and with a takeoff weight of 70,000 kg (150,000 lb). By the mid-1930s, the trend in military aviation shifted towards smaller and faster aircraft and the TB-6 was cancelled. ANT-28 was a proposed cargo version.[1]

A 0.21:1 scale two-seat glider was built by AGOS ([otdel] Aviatsii, Ghidroaviahtsii i Opytnovo Samolyotostroyeniya - [section for] aviation, hydro-aviation and experimental construction) and test-flown by B.N. Kudrin, to evaluate the aerodynamic soundness of the design before work was started on the first prototype.[2]
