Was the B-17 originally intended for sea reconnaissance?
Short answerSome aircraft reflected that role, but there were not enough suitable B-17s in Hawaii to solve the reconnaissance shortage.
NotesA viewer notes that the B-17 was originally ordered with sea reconnaissance among its roles and that some aircraft carried observation blisters. The point is accepted for some examples. The relevant limitation was whether enough B-17s could search over water where Hawaii needed them. Too few suitable aircraft were in place to turn the capability into continuous coverage of the approaches.
