The Boeing B-17E was an extensively modified and improved version of the basic B-17D design. The most obvious change was the redesigned tail with its distinctive vertical stabilizer and fairing. A tail gunner was added because combat experience showed the earlier models extremely vulnerable to attack from directly aft. The waist gunner windows were changed from teardrop to larger rectangular shaped windows. The ventral "bathtub" turret of the D model was initially replaced by a Bendix remote-controlled and remote-sighted belly turret. The Bendix turret was replaced by a Sperry ball turret starting with the 113th B-17E built. A Bendix turret also was added to the top forward fuselage just behind the cockpit.
A total of 512 B-17Es were built by Boeing in 1941 and 1942. The basic E model design was constantly being modified to incorporate needed improvements pointed out, in part, by combat crews whose lives depended on the aircraft.
The first Army Air Force bombing mission in Europe was carried out by B-17Es of the 97th Bomb Group against the Rouen-Sotteville railroad marshalling yards in France on Au. 17, 1942.
