Andrew Thomas outlines the significant role played by Boeing’s B-17 Flying Fortress in Coastal Command’s battle against the U-boats during World War Two
In the spring of 1941, the first of 20 Boeing B-17Cs, known in the RAF as the Fortress Mk.I, was delivered to 90 Squadron for high-level daylight bombing.

Although not suitable for overland bombing, its range and endurance made the Fortress attractive to Coastal Command, which desperately needed appropriate aircraft to patrol the Atlantic convoy routes.
