When comparing the Courageous-class and Lexington-class aircraft carriers of World War II, the Lexington-class was significantly larger in terms of displacement, dimensions, and overall capabilities.
1. Courageous-class (Royal Navy)
Originally designed as battlecruisers during World War I, the Courageous-class ships were later converted into aircraft carriers under the Washington Naval Treaty. The two carriers of this class were HMS Courageous and HMS Glorious (a third sister ship, HMS Furious, was slightly different).
Length: 786 feet (239.3 meters)
Displacement: Approximately 22,500 tons (standard load)
Flight Deck: Full-length deck but narrower compared to later carrier designs
Aircraft Capacity: Around 48 aircraft
Speed: 30 knots
While innovative for their time, the Courageous-class carriers were relatively small by World War II standards and vulnerable to attack due to their light armor and exposed design. HMS Courageous was sunk early in the war by a German U-boat in 1939.
2. Lexington-class (United States Navy)
The Lexington-class carriers, originally designed as battlecruisers like the Courageous-class, were converted into aircraft carriers as well. The two ships of this class were USS Lexington (CV-2) and USS Saratoga (CV-3).
Length: 888 feet (270.7 meters)
Displacement: Approximately 33,000 tons (standard load), up to 41,000 tons fully loaded
Flight Deck: Much broader and sturdier compared to the Courageous-class
Aircraft Capacity: 78–91 aircraft (varied depending on mission requirements)
Speed: 33.25 knots
The Lexington-class carriers were among the largest and most powerful aircraft carriers of their era. They were well-armed, with better survivability features compared to the Courageous-class. USS Lexington played a key role in the early Pacific battles before being lost at the Battle of the Coral Sea in 1942. USS Saratoga survived the war and was used as a test ship for nuclear weapons.
