Boeing · United States · first flew 1941 · bomber

The Boeing B-17E Flying Fortress was the first mass-produced B-17 variant to incorporate major defensive improvements, including a redesigned enlarged tail fin, a powered dorsal turret, a ventral 'bathtub' turret, and a tail gun position. It was the first B-17 used in large-scale USAAF bombing raids.

History

The B-17E resulted from combat experience gained by the RAF with earlier B-17 marks, which revealed severe defensive blind spots. Boeing redesigned the rear fuselage with a larger fin and rudder, added a Sperry dorsal turret, and introduced the tail gun position for the first time. A total of 512 were built, seeing action in the Pacific and early Eighth Air Force raids from England in 1942.

Variants

The B-17E preceded the B-17F, which further refined the defensive armament and introduced a chin position. The E model introduced the features that became standard on all subsequent Flying Fortress variants.

Where you'll see it

Served with the USAAF in the Pacific (including at Midway and Guadalcanal) and with the newly formed Eighth Air Force in England. Some were converted to transport and training roles.
