The machinery proposal scales up contemporary destroyer equipment. The Tribal comparison uses three Admiralty three-drum boilers and two turbine sets for 44,000 shaft horsepower, while the L and M classes are described with two boilers and two Parsons turbines for 48,000. The old cruiser is assumed to have room for four boilers driving four turbines at a proposed 64,000 shaft horsepower. Replacing twelve older Yarrow boilers should reduce weight, improve efficiency, and release internal space.

Scaling destroyer machinery for the old cruiser
Tribal and L/M-class machinery provides the comparison for a proposed four-boiler, 64,000-shaft-horsepower plant.
