The Boeing B-17 ‘Flying Fortress’ boasts a remarkable legacy, as both a strategic weapon and an enduring symbol of American air power during the Second World War. Designed as a large, multi-engine bomber with substantial defensive armament, the B-17 was introduced in 1938. First used in combat with the RAF in 1941, carrying out bombing raids in France, its poor performance suggested that improved defences and greater bombing accuracy were needed. Later variants like the B-17G were more effective

The Bendix Chin Turret adopted by the B-17G was a defensive feature from the YB-40, a ‘gunship’ B-17 experiment that proved too heavy to be practical as part of the formation. #ww2 #B17 #b17flyingfortress #flyingfortress #wwii | Daniel J Wheatcroft
