Yorktown-class aircraft carrier

Initially, the development plan for the class envisioned a 17,000-ton design that would allow the Navy to build three ships and stay within the 135,000-ton Washington Naval Treaty limit on aircraft carrier tonnage.

However, this design could not achieve the desired high operating speed without sacrificing protection features and air wing capacity.

In addition, the London Treaty of 1930 required that the USS Langley be added into the tonnage limits, no longer being classified as an "experimental" carrier.

In addition to the engineering constraints, it was becoming evident that larger air groups and antiaircraft batteries would be easier to command from an island design.

USS Ranger proved to be unable to withstand rougher weather in the Pacific, while lack of virtually any protective features soon relegated her to a training ship.

Damaged by Japanese carrier aircraft, Yorktown returned to Pearl Harbor and was hastily repaired in time to participate in the Battle of Midway.

All three carriers suffered severe losses among their air groups, most notably Hornet's Torpedo Squadron 8, which lost 15 aircraft with only a single surviving airman.

Attempts to scuttle the ship by her escorts failed, and she was left adrift before finally being sunk by Japanese destroyers on 27 October 1942.

Enterprise aircraft assisted in finishing off the heavily damaged battleship Hiei and were instrumental in destroying the Japanese transport fleet, thereby ending Japan's last serious attempt at reclaiming the island.

After a lengthy overhaul and repair period at Bremerton, Washington, Enterprise joined the Central Pacific Fleet as part of the Fast Carrier Task Force.

The Yorktowns had proved to be vulnerable to torpedoes, and while undergoing repairs at Bremerton, Washington, from July to October, 1943, Enterprise received an extensive refit, which included an anti-torpedo blister that significantly improved her underwater protection.

Stricken from the list in 1959 after multiple attempts to preserve her as a museum and memorial, ex-Enterprise met her fate in the breaker's yards at Kearny, New Jersey, in 1960, although several artifacts were retained.
