The Defiant's Rationale

摘要

During the 1930 a major area of uncertainty in most air forces concerned the effectiveness of the defensive crossfire produced by a large force of bombers flying in close formation. Would it be powerful enough to defeat attacks by intercepting single-seat fighters attacking from the rear? In the RAF the consensus of opinion was that a formation of its latest bomber type, the Vickers Wellington, equipped with powered gun-turrets, probably could fight its way through to targets without suffering heavy losses.
