The machinery layout combined two Shakespeare-class destroyer plants, each producing about 40,000 horsepower. Together they gave Emerald a stated top speed of 33 knots and a range of 8,000 nautical miles at 15 knots. Speed and endurance suited a cruiser expected to search widely for surface raiders. Emerald is described as the purest completed expression of the original E-class idea.
