Twelve fully supported Type 45 destroyers

What if all twelve Type 45 destroyers had been built with their planned support and fuller equipment?

Britain would have a much more available and versatile air-defence fleet with fewer self-created power and support problems.

Twelve Type 45 destroyers with adequate support infrastructure would, in this counterfactual, suffer fewer availability problems. The response also points to originally considered machinery options, including additional turbines or diesel generators. Space retained for extra diesels is given as a reason later generator additions were feasible. Mark 41 launchers fitted from the beginning could have enabled Tomahawk use. Joining the SM-3 programme is a further possibility that could have added ballistic-missile defence, rather than a capability guaranteed by the launcher alone.
