And now we have the Gotha G-IV. As mentioned before, the Gotha series of G-type were quite famous for being the "type of choice" to carry out the strategic aerial bombardment of England during WW I. It was also the first of the Gotha types to feature the "tunnel"-a cut-out in the lower fuselage allowing the rear gunner/observer to fire through the fuselage at an aircraft attack from below and behind. Also like the Fokker D-VII mentioned previously, the Gotha G-IV was built by manufacturing firms other than the original designer. In this case, Siemens-Schuckert Werke (SSW), and Luft Verkehrs Gesellschaft (LVG).
