Sukhoi Su-8 or DDBSh ( _ru. Су-8 ДДБШ - Двухмоторный Двухместный Бронированный Штурмовик - Twin-engine two-seat armored ground attack aircraft) was a Soviet prototype heavy attack aircraft of the Great Patriotic War.

Development

While Sukhoi was perfecting the light Sukhoi Su-6 attack aircraft, the OKB also developed the massive, heavily armed and armored Su-8. Two prototypes were completed in 1943 and underwent factory testing in 1944, but did not advance to government trials or production due to the unavailability of M-71 engines.Shavrov 1994] An attempt to re-engine the aircraft with Mikulin AM-42 engines did not see further development.

The Su-8 was of mixed construction. The cockpit area was armored, with an aluminum mid-fuselage and a wooden monocoque tail. The wings were of steel and aluminum construction with plywood outer sections. The twin rudders were of all-metal construction. In addition to the cockpit, the engines, the fuel tanks, and the oil coolers were fully armored, with a total armor weight of 1680 kg (3,705 lb), more than twice as heavy as the armor shell on an Ilyushin Il-2.
