The missing resilience in British carrier dry-dock capacity

Does the ability to switch Britain's carriers between yards solve their maintenance vulnerability?

It helps, but a third carrier and additional large dry docks would provide much stronger resilience.

The ability to alternate the Queen Elizabeth-class carriers between available facilities shows useful flexibility. Two irreplaceable ships nevertheless create concentration risk when only a small number of yards can accept them. Another suitable dock at Portsmouth and a comparable facility near Cammell Laird would reduce that risk. A third carrier would pair hull redundancy with repair capacity rather than treating clever scheduling as a complete resilience plan.
