Tupolev ANT-16 (also known as TB-4; Russian: Тяжелый Бомбардировщик – Heavy Bomber) was an experimental heavy bomber aircraft designed and tested in the Soviet Union in the early 1930s. Conceptually representing evolution of the TB-3 bomber ANT-16 was designed under the doctrine that size and payload were more important for a bomber than speed because it would be able to protect itself with defensive armament.
