What two, three, or four ships buy a navy

The F-35B answer becomes a clear explanation of alliance design assumptions and the force-structure arithmetic behind fleet availability.

Question

Why were US Marine Corps F-35Bs embarked on Queen Elizabeth, and what does a two-ship carrier class imply?

Short answer

Allied F-35B interoperability was planned from the start, while buying only two carriers accepts readiness risk; three usually preserve a capability and four can guarantee a continuous deployed requirement more reliably.

Notes

Queen Elizabeth was conceived when NATO operations and allied air groups were expected to be normal, so US or Italian F-35B embarkation formed part of the concept. Maintenance, training, and operational cycles make a two-ship fleet vulnerable to gaps. Three or four ships offer progressively more resilience, with four supporting a much firmer continuous commitment. Ballistic-missile-submarine fleets illustrate the same connection between platform count and strategic expectations.
