HMS Unicorn as a mobile aircraft workshop

HMS Unicorn shows what serious expeditionary aviation support looked like. Her extensive machine shops could be divided between British- and American-built engines without an appreciable loss in the volume of British repair work. Damaged aircraft could pass through the ship and return to the fleet in restored condition while operations continued at sea. In a counterfactual early war with Japan, this repair flow would have made Unicorn exceptionally valuable. The example extends the Walrus engine discussion into the practical role of a fleet repair ship.
