Boeing B17G Flying Fortress / Fortress MKIII

Without doubt, the definitive version of the Flying Fortress was the B-17G and this last mass-produced version of the aircraft was manufactured in more numbers than all previous versions combined – the B-17G was a magnificent fighting aeroplane. Addressing all the shortcomings of the previous combat variants, the B-17G incorporated a number of significant improvements, specifically around the placement and upgrading of defensive armament. The combat experiences of crews flying the earlier versions of the B-17 were crucial in producing this definitive US heavy bomber.
