Henderson's fast Dale-class fleet oilers form the worked example for an earlier escort-carrier conversion. Some ships of the type later received landing-ship gantries while retaining their ability to carry and deliver fuel. A flight deck and modest hangar could likewise have been built above the tanker function. Experience with the First World War Spider's Web patrol system and later interwar exercises already treated aircraft as part of anti-submarine work, so the operational case did not begin in 1939. A dual-purpose oiler-carrier would sacrifice some merchant utility but add fighter and patrol coverage while continuing to support the escorts it accompanied.

Dale-class tankers as carrier conversions
The Dale-class fleet oilers provide a concrete conversion path because related wartime alterations preserved fuel capacity beneath a large new upper-deck role.
