Unicorn's turbines sit on a scale between cruisers and battleships

Did HMS Unicorn and the 1942 light-carrier program use cruiser turbines?

They used carrier turbines that were closer in scale to cruiser machinery than battleship machinery, rather than simply copying a cruiser plant.

A rigid label of cruiser or battleship turbines does not fit the machinery. Unicorn and the later light carriers used turbine sets designed for carrier requirements. Their size placed them closer to cruiser machinery than to a battleship plant, but the distinction was mainly one of scale. A shared power range does not mean that two ship types used identical propulsion systems.
