Ilyushin DB-3

From Wikipedia, the free encyclopedia

The Ilyushin DB-3 (for Дальний бомбардировщик - Dalniy Bombardirovschik - "long-range bomber") was a Soviet bomber aircraft of World War II. It was a twin-engined, low-wing monoplane that first flew in 1935. It was the precursor of the Ilyushin Il-4 (originally named DB-3f). 1,528 were built. The names TsKB-30 and DB-3 were used in 1936-1938. Later aircraft were named DB-3b.

A modified aircraft, (TsKB-30 "Moskva") flew from Moscow to Spassk-Dalnyj (7580 km) in 24 h 36 min (an average speed of 307 km/h) mostly at 7,000 m under control of V.K.Kokkinaki and A.M.Berdyanskij, then from Moscow to the US (Miscow Island) in 22 h 56 min. covering 8,000 km with 348 km/h average airspeed (Kokkinaki and M.Kh.Gordienko).

On the night of August 8, 1941 fifteen DB-3T torpedo bombers of the Baltic Fleet dropped the first Soviet bombs on Berlin. From August 11, DB-3fs of the VVS resumed bombing.

In 1939, 30 DB-3 were supplied to the Republic of China Air Force and they saw heavy actions against targets in Wuhan region from their bases in Sichuan (mostly used by the 8th Group), before being replaced by B-24 Liberator in 1943.

Suomi sai talvisodassa sotasaaliiksi 4 DB-3-konetta, joista yksi saatiin lentokelpoiseksi ennen talvisodan loppua. Jatkosodassa Pommituslentolaivue 46:lla oli käytössään myös 4 kappaletta Il-4-koneita, jotka ostettiin Saksalta ja haettiin Ukrainasta ([1]).

The Finns came over four DB-3Ms during the Winter War and during 1941 they purchased a further four DB-3f/Il-4s from German surplus stocks.
