The mighty TB 3 was the world’s most advanced heavy bomber
throughout most of the early 1930s. Despite archaic looks, it was a
solid, capable design and served admirably through most of World
War II.
Russian proclivities for giant aircraft dated back to the
Sikorsky Ilya Muromets of 1914, and in time they accumulated
sufficient knowledge and expertise to build even bigger machines.
In 1925 Andrei N. Tupolev fielded the TB 1, an advanced metal
monoplane that was the best in its class. Three years later he
received orders to build a four-engine bomber with prodigious range
and lifting abilities. He complied, and the new TB 3 emerged as an
allmetal, low-wing monoplane with fixed landing gear and a crew of
ten. Initial models were covered in corrugated metal, stressed to
great strength. Consequently, in 1931 the TB 3 could lift more than
12,000 pounds on short flights—a payload unmatched until the Avro
Lancaster and Boeing B-29 Superfortress a decade later. Stalin
appreciated the propaganda value of such huge machines, and during
the 1934 May Day parade no less than 250 TB 3s overflew Moscow. The
production run concluded by 1938 with 808 machines built, with
latter versions possessing smooth, stressed skin.
In service the TB 3s proved ruggedly adaptable and easily
maintained. They made international headlines by transporting
scientific teams during a number of expeditions to the Arctic
Circle. TB 3s were also used during the mid-1930s to train
embryonic Soviet parachute forces, who deployed by jumping off the
aircraft’s broad wing. An even more controversial use was the
so-called parasite experiments, whereby the lumbering craft carried
their own fighter escorts. One TB 3 could successfully carry,
launch, and retrieve no less than three I 15 biplanes and two I 16
monoplanes. The giant craft was marginally obsolete at the start of
the 1941 German invasion and, being vulnerable to enemy fighters,
served as a night bomber and transport. All these versatile
machines were retired from service by 1944.
