Cutting Type 45 numbers raised unit and readiness costs

Why does Britain spend so much yet receive so few deployable ships?

Small classes absorb design costs across fewer hulls and force ships to surge, which raises maintenance costs and weakens retention.

Operational use and training continually consume maintenance money, while salt water damages ships and desert sand wears aircraft. Deferred work grows more expensive as additional faults accumulate. The Type 45 example contrasts six ships for about £6 billion with an estimated twelve for about £8.4 billion, reducing average cost from roughly £1 billion to £700 million. The additional six are variously estimated at £1.8-2.4 billion, or about £3 billion with Mark 41 launchers, so these are illustrative counterfactual costs. Twelve ships would normally permit roughly four to six to be available and reduce pressure to interrupt maintenance for a surge. More command and senior-rate appointments could also improve retention. A later batch could have incorporated additional diesel power after the propulsion difficulties became understood, helping the first six undergo repairs more gradually.
