Junkers Ju 87 RAF aircraft on the ground and a great many of the airfield's buildings. Detling was not an RAF Fighter Command station. The Battle of Britain proved for the first time that the Junkers Ju 87 was vulnerable in hostile skies against well-organised and determined fighter opposition. The Ju 87, like other dive bombers, was slow and possessed inadequate defences. Furthermore, it could not be effectively protected by fighters because of its low speed, and the very low altitudes at which it ended its dive bomb attacks. The Stuka depended on air superiority, the very thing being contested over Britain. It
Junkers J 2 fuselage directly below the stabilizer's leading edge root. The wings had at least three different airfoil changes between root and tip, and had sections of them electrically roll-welded for stronger, more continuous bonding for greater strength. The resulting aircraft was intended to be smaller than the J 1 demonstrator, but with its steel structure, it almost equalled the J 1's completed weight. One feature pioneered in the J 2 that would also be used in later all-metal monoplanes designed and built by Junkers in World War I, was a "unitized" forward fuselage structure, combining the engine mount, wing roots and
