Courageous-class aircraft carrier
The Courageous class, sometimes called the Glorious class, was the first multi-ship class of aircraft carriers to serve with the Royal Navy. The three ships—Furious, Courageous and Glorious—were originally laid down as Courageous-class battlecruisers as part of the Baltic Project during the First World War.
