A proposed sister ship becomes a command-support carrier

One wargame scenario orders a proposed Unicorn sister, tentatively called Ocean, alongside her and completes the second ship as a command carrier. The scenario keeps Unicorn in maintenance service while using the sister's volume for a major task-force headquarters. It also assumes Henderson persuades Churchill to continue carrier construction, potentially bringing Implacable and Indefatigable into service much earlier. The combination would give Eastern and Pacific Fleet commanders dedicated command capacity without consuming scarce accommodation aboard operational fleet carriers. This is explicitly counterfactual, but it shows how readily Unicorn's support-ship architecture could be adapted to another fleet-level logistical need.
