Improved Implacable class aircraft carrier

The Implacable-class supercarriers, commonly know as the Improved Implacable class, are a class of aircraft carriers built for the Royal Navy and other Commonwealth and Allied navies. The name of the class indicates the roots of the class' design in the Implacable-class carriers of World War II. Currently, no Improved Implacable-class ships remain in service with the Royal Navy, but some remain in service with other navies. Improved Implacable-class ships are conventionally powered, have an overall length of 326.14 meters (1070 ft) and a displacement of 82,000 tons, and can carry up to 90 aircraft.

The Improved Implacable-class ships use angled flight decks in a CATOBAR arrangement.
