5 Worst Aircraft Carriers Ever Put to Sea

5 Worst Aircraft Carriers Ever Put to Sea

A list of total shame. 

Building an aircraft carrier is difficult business. Many of the world’s great navies started by converting other ships into carriers, a practice that resulted in a few successes, and more than a few failures. Other navies worked their way up by experimentation. With China recently launching its first domestically built carrier, and Japan considering the conversion of its Izumos into fleet carriers, it’s worth considering some of the more egregious failures in world aircraft carrier construction.

HMS Eagle

HMS Eagle, originally Almirante Cochrane , was designed as a battleship. Intended to fill out a battle squadron in the Chilean Navy, work on Almirante Cochrane ceased at the beginning of World War I. After the war, the Chileans no longer wanted the battleship, leaving a large hulk without much to go for it. The Royal Navy had already experimented with several conversions, and decided to use the battleship hull to construct another aircraft carrier.

The results were not particularly satisfactory. On a displacement of 23,000 tons, Eagle could make twenty-four knots and carry twenty-five aircraft. These specs left her uncompetitive with Japanese and American aircraft carriers, and even with the other conversions in the Royal Navy; the three Courageous-class carriers were faster and could carry more planes. Commissioned in 1924, she was updated during the interwar period, but not extensively reconstructed.

Despite her drawbacks, HMS Eagle saw a great deal of service in the early years of World War II. She patrolled the Indian Ocean, and later participated in the Mediterranean campaign, where her slow speed was less of a drawback. But on August 11, 1942, she was hit by four torpedoes from U-73 while covering a resupply convoy to Malta. She sank in four minutes.

Bearn

France’s first effort at an aircraft carrier didn’t go well. Converted in 1927 from an incomplete Normandie-class battleship, Bearn was quite large, displacing 28,000 tons full load. However, she could only reach about twenty-one knots, making it difficult to integrate her into the fleet. Bearn was equipped to carry about forty aircraft, although the slow development of French naval aviation meant that the planes were generally not competitive with foreign counterparts.

The French navy expected to use Bearn in an experimental role, in anticipation of the construction of purpose-built carriers. However, austerity delayed the construction of those ships, and at the onset of war Bearn remained France’s only aircraft carrier. She operated with a task forces that hunted German raiders, but never launched a combat sortie. In May 1940, she carried France’s gold bullion to North America. On the return trip she was supposed to bring a load of combat aircraft, but France surrendered before Bearn arrived. She put in at Martinique, where she remained for much of the war.

Bearn was turned over to the Free French in 1943. The United States saw little urgency in returning the big, slow carrier to service, but eventually got around to refitting Bearn in 1944. She served out the last days of World War II as an aircraft transport, a role she continued in the early stages of the Indochina Wars. She was scrapped in 1967, having never launched a sortie in anger.

HIJMS Kaga

Japan fully understood the limitations of battleship conversions, and had initially intended to convert the battlecruisers Akagi and Amagi, which were long and had high top speeds. Unfortunately, the Great Kanto earthquake badly damaged Amagi, forcing the Japanese to spare the incomplete battleship Kaga as a substitute. As originally constructed in 1928, Kaga was not suitable; she had three flight decks, weird funnel arrangements and a variety of other small problems. A reconstruction in the mid-1930s rectified some of these issues, but left Kaga with potentially serious damage control vulnerabilities, and a speed shy of the rest of the 1st Air Fleet ( Kido Butai ). In her final configuration, she displaced a massive 38,000 tons, but could make twenty-eight knots, and carry seventy-two aircraft.

Kaga was nevertheless an active participant in the Sino-Japanese War, and in the first six months of the Pacific War. She missed the Indian Ocean raid after suffering damage from an uncharted reef. She was back in service for the Battle of Midway, however. On June 4, 1942 four bombs dropped by U.S. Dauntless dive bombers struck Kaga. The limitations of her damage-control system soon became apparent, and fires engulfed the ship. Nine hours later, Kaga was scuttled by torpedoes from accompanying destroyers.

USS Ranger

USS Ranger was the first purpose-built U.S. aircraft carrier, and the fourth carrier to join the U.S. Navy (USN). After devoting an immense percentage of its treaty tonnage to the battlecruiser conversions USS Lexington and USS Saratoga, the USN hoped that it could create a formidable unit on a much smaller hull. As commissioned in 1934, Ranger displaced 14,000 tons, could make twenty-nine knots, and could operate seventy-six aircraft (although in practice fewer were carried).
