Question: does the b 52 have a tail gunner

Answer: Yes, A tail gunner or rear gunner is a crewman on a military aircraft who functions as a gunner defending against enemy fighter attacks from the rear, or ``tail'', of the plane. The tail gunner operates a flexible machine gun emplacement in the tail end of the aircraft with an unobstructed view toward the rear of the aircraft. While the term tail gunner is usually associated with a crewman inside a gun turret, the first tail guns were operated from open apertures within the aircraft's fuselage, like in the Scarff ring mechanism used in the British Handley Page V/1500 (a 1918 aircraft), and also, in the most evolved variants of this type of air-to-air anti-aircraft defense, they may also be operated by remote control from another part of the aircraft, like in the American B-52 bombers (an aircraft first introduced in 1955 but still in service).
