Fortress Union Jack Low Profile Dad Hat
Later, more advanced versions - B-17F (Fortress Mk II) and B-17G (Fortress Mk III) - were delivered. Rather than continuing strategic bombing, the RAF repurposed these aircraft for electronic warfare, long-range maritime patrols, and special operations. Notably, B-17s served with No. 100 Group RAF, specialising in radio countermeasures and bomber support missions to jam German radar and communications during RAF Bomber Command night raids.
Some B-17s were also used by RAF Coastal Command for anti-submarine patrols in the Atlantic. The RAF Flying Fortresses operated in smaller numbers compared to the USAAF, but provided crucial support roles, especially in disrupting German air defences.
RAF B-17s were retired shortly after the war ended, their role eclipsed by newer British and American bombers.
