Where prewar Unicorn-class support ships would deploy

If the Royal Navy had received two Unicorn-class aviation-support ships before the war, where would they have deployed?

One was intended for the China Station and one for the eastern Mediterranean, providing forward aviation logistics ahead of fleet movements.

One planned Unicorn-class support ship would go to the China Station. The other would be in the eastern Mediterranean, ready to deploy onward. Their forward positions would establish logistical support for fleet manoeuvres and movements. They could sustain themselves there and be ready when the larger fleet arrived.
