How many tankers were needed to keep Royal Navy forces in Europe moving?
Short answerThe fleet did not rely mainly on at-sea tankers there; civilian tankers delivered fuel to nearby ports and bases.
NotesLogistical systems must match their theater. British forces in European waters operated near a dense network of friendly ports. Civilian tankers could bring fuel into those bases, where warships replenished under protection. The requirement therefore differed fundamentally from sustaining a mobile fleet across the central Pacific.
