According to the National Museum of the U.S. Air Force, "The Norden bombsight functioned as a part of a whole system. As the bomber approached its target, the bombardier entered data about wind direction, airspeed and altitude into the bombsight's analog computer, which calculated wind drift and provided the correct aim point. An internal gyroscope provided the stability necessary for using the telescopic sight at high altitudes. When connected to the Sperry C-1 Autopilot, the Norden bombsight provided unprecedented accuracy."
Although not original to the plane, this Norden bombsight is representative of what the B-17 flew with in World War II.
