The Midway-class was a class of three United States Navy aircraft carriers. The lead ship, , was commissioned in September 1945 and decommissioned in 1992. was commissioned in October 1945, and taken out of service in 1977. was commissioned in April 1947, and decommissioned in 1990.
History
1940s
The CVB-41-class vessels (then unnamed) were originally conceived in 1940 as a design study to determine the effect of including an armored flight deck on a carrier the size of the . The resulting calculations showed that the effect would be a reduction of air group size—the resulting ship would have an air group of 64, compared to 90-100 for the standard Essex-class fleet carriers. As it progressed, the design also became heavily influenced by the wartime experience of the Royal Navy's armored carriers:
The concept went to finding a larger carrier that could support both deck armor and a sufficiently large air group. The weight-savings needed to armor the flight deck were achieved by removing the planned cruiser-caliber battery of guns and reducing the 5-inch antiaircraft battery from dual to single mounts. Unlike the Royal Navy's aircraft carriers, for which the armored deck was part of the ship structure, the Midway class retained their "strength deck" at the hangar deck level and the armored flight deck was part of the superstructure. They would be the last USN carriers to be so designed; the immense size of the succeeding supercarriers would require a new deep-hulled design carrying the strength deck at the flight deck level to produce a stronger and lighter hull.
The heavily subdivided arrangement of the machinery spaces was based on that of the , while the two inner propeller shafts were partially enclosed in skegs, similar to contemporary battleship construction. While the Essex-class carriers had eight main engineering compartments, the Midway-class had 26, including twelve boiler rooms well off the centerline and four widely separated engine rooms. More extensive use of electric arc-welding than in previous warships reduced the weight by about 10 percent of what would have been required for riveted structural assembly.
The resulting Midway-class carriers were very large, with the ability to accommodate more planes than any other carrier in the U.S. fleet (30–40 more aircraft than the Essex class). In their original configuration, the Midway-class ships had an airwing of up to 130 aircraft. It was soon realized that the coordination of so many planes was beyond the effective command and control ability of one ship. However, their size did allow these ships to more easily accommodate the rapid growth in aircraft size and weight that took place in the early jet age. The forward flight deck was designed for launching 13-ton aircraft; and the aft flight deck was designed for landing 11-ton aircraft, assuming in-flight expenditure of fuel and ordnance.
While the resulting ships featured excellent protection and unprecedented airwing size, they also had several undesirable characteristics. Internally, the ships were very cramped and crowded. Freeboard was unusually low for such large carriers; in heavy seas, they shipped large amounts of water (only partially mitigated by the fitting of a hurricane bow during the SCB-110/110A upgrades) and corkscrewed in a manner that hampered landing operations. The follow-up Forrestal-class featured a deeper hull that had more freeboard and better seakeeping.
In contrast with the earlier , and -classes, the beam (width) of the Midway-class carriers meant that they could not pass through the Panama Canal.
Although they were intended to augment the US Pacific fleet during World War II, the lead ship of the class, , was not commissioned until 10 September 1945, eight days after the Surrender of Japan.
While Midway and Coral Sea followed the US Navy's policy of naming aircraft carriers after battles (two Casablanca-class escort carriers gave up their names for the larger ships) USS Franklin D. Roosevelt inaugurated the policy of naming aircraft carriers after former US Presidents that the US Navy generally follows today.
1950s
None of the class went on war cruises during the Korean War. As the three ships became essential to the Navy's strategic nuclear weapons role in Europe, they were mainly deployed to the Atlantic and Mediterranean. Until the availability of the Forrestal class, they were the premier commands sought by senior naval aviators. They were "admiral makers" for many of their commanding officers including future CNOs George Whelan Anderson Jr. and David L. McDonald.
