The Tupolev ANT-16 (also known as the TB-4; Russian: Тяжелый Бомбардировщик – Heavy Bomber) was an experimental heavy bomber aircraft designed and tested in the Soviet Union in the early 1930s.

[1] The sole prototype first flew on 3 July 1933 with M. M. Gromov at the controls.

The test flight program was completed by 29 September 1933 with disappointing results.

A proposal to re-equip the aircraft with Mikulin AM-35 engines of 933 kW (1,250 hp) was not implemented.
