Which Royal Navy losses would still occur?

Which Royal Navy ships would still be lost in the altered war?

Royal Oak probably remains lost, while many later Mediterranean and Atlantic losses disappear in their historical form, though other ships could still be lost in different ways.

The counterfactual does not make the Royal Navy immune to casualties. Royal Oak had already been sunk before the point of divergence and therefore remains a loss. Ships historically damaged or sunk by Italian frogmen, Mediterranean operations, or U-boats using French Atlantic bases may escape those exact fates. A fixed survivor list would be misleading because a different war would create different dangers and losses.
