Six Fort Victoria ships as protected one-stop replenishment

What difference would it make if the Royal Fleet Auxiliary received all six planned Fort Victoria-class replenishment ships?

Britain would gain a deeper fleet of one-stop fuel-and-stores ships, potentially with enough self-defence to support carrier operations closer to the threat area.

Fort Victoria combined stores and fuel in one ship, allowing the same auxiliary to replenish both. The counterfactual becomes more consequential if all six ships also receive their intended Sea Wolf systems and later CAMM upgrades. That defensive armament could let them refuel and rearm a task group somewhat closer to the combat zone, although they would remain auxiliaries with limits on the threats they could face. Allies might value access to that capability without choosing to build equivalent ships themselves. Providing a scarce form of support could therefore give Britain additional influence within an allied operation.
