Heinkel He 177 Greif

Heinkel He 177 Greif 

After the scrapping of German plans for a strategic bombing force in 1936, the Luftwaffe abandoned plans to develop a heavy bomber until in 1938 the RLM approached the Heinkel company with a requirement for such an aircraft, resulting in the Heinkel He 177 Greif (Griffon), a four-engine mid-wing aircraft in which the 1,000-hp (746-kW) DB 601 engines were coupled in pairs (termed DB 606s) to drive single propellers. The first aircraft, the He 177 VI, was flown on 19 November 1939. Continuing engine overheating problems as well as persistent structural failures delayed production, the first He 177A1 not reaching I/KG 40 for operational trials until July 1942; in the course of these He 177s took part in raids on the UK, but generally they proved disappointing m service.
 
Several subvariants of the He 177A-3 were produced, including the He 177A-3/R3 which could carry three Hs 293 antishipping missiles, the He 177A-3/R5 with 75-mm gun in the ventral gondola and the He 177A-3/R7 torpedobomber. He 177A-3s were used by KGr 2 to fly supply missions to the beleaguered German forces at Stalingrad in January 1943. The He 177A-5 incorporated a stronger wing to carry heavier external loads, and a small number was converted to the Zerstörer role with 33 upward-firing rocket tubes in the space normally occupied by the bomb bays. Small numbers of He 177A-5s returned to the night attack on the UK early in 1944; this version proved to be the last to serve with the Luftwaffe (bombers being afforded low priority during the last year of the war), but many interesting projects continued to be pursued, including one involving the conversion of He 177 V38 as a carrier of Germany's atomic bomb, which m the event did not materialize. About 1,160 production and 30 prototype He 177s were built.
