Implacable was designed for long-range night strikes, continuing reconnaissance, and combat air patrols. The stated deep-load displacement of 32,670 tons supported 81 aircraft in flying condition. Protection included a 4.5-inch waterline belt and 3-inch flight deck, with 2-inch hangar sides and bulkheads and additional magazine armor. Its 148,000 shaft horsepower and 32.5-knot speed were below Shokaku's 160,000 shaft horsepower and 34.5 knots. The quoted range was a theoretical 12,000 nautical miles at 10 knots. The comparison shows how Britain accepted less speed to carry protection and a substantial operational air group.
