The aging logistics ships behind a British carrier group

Does the British carrier group have enough logistics ships?

Enough for current needs, but the auxiliaries are old and require replacement soon.

The available auxiliaries were sufficient for the carrier deployment under discussion, which separates an immediate shortfall from a longer replacement problem. Modernization can keep aging ships useful for a time. Their machinery, hulls, and support systems cannot be extended indefinitely. Carrier reach therefore depends on replacing the tankers and stores ships that sustain aviation and escort operations far from home.
