The correct answer is the Blohm & Voss BV 222 Wiking. The BV 222 Wiking six-engined flying boat was originally ordered in September 1937 by Deutsche Lufthansa as a civil flying boat, but was quickly taken over as a military transport. A dorsal gun turret was added behind the cockpit. Rearward facing machine gun turrets were added on both wings. Access in flight through the wing was via a tubular wing spar of a metre in diameter. Engineers could also reach the two stroke diesel engines in flight via the same spar.
