Convoy practice protected logistics ships

What plans did the Royal Navy have for escorting logistics vessels?

It retained and exercised convoy techniques, often using RFA ships as the vessels that escorts protected.

Interwar exercises often used Royal Fleet Auxiliary ships as the merchant vessels being convoyed. The escorts thereby practised protecting the same kinds of vulnerable vessels on which fleet endurance depended. The practice kept convoy skills alive between the wars. It linked interwar convoy doctrine directly to moving fuel and stores safely rather than treating logistics as separate from operations.
