Midway-class aircraft carrier

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 s 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 Chief of Naval Operations George Whelan Anderson Jr. and David L. McDonald.

During the 1950s, ''Midway'' and ''Franklin D. Roosevelt'' underwent the SCB-110 modernization program (similar to SCB-125 for the ''Essex'' class), which added angled flight decks, steam catapults, mirror landing systems, and other modifications that allowed them to operate a new generation of larger and heavier naval aircraft. ''Coral Sea'' had a variant modernization program called SCB-110A with an angled deck 3 degrees greater than the other two.

1960s

All three of the ''Midway'' class made combat deployments in the Vietnam War. deployed to the Gulf of Tonkin six times, deployed on three occasions, and made one combat deployment before returning to the Mediterranean.

In the late 1960s, ''Midway'' underwent an extensive modernization and reconstruction program under SCB 101.66, which proved to be controversial and expensive and thus was not repeated on the other ships. While $82 million had been budgeted for the modernization, the actual cost was $202 million, in comparison to $277 million for simultaneous construction of the brand-new .

''Roosevelt'' instead received an austere $46 million refit (SCB 103.68), enabling her to operate the Grumman A-6 Intruder and LTV A-7 Corsair II. In July 1968, ''Roosevelt'' entered Norfolk Naval Shipyard for her 11-month modernization program. The forward centerline elevator was relocated to the starboard deck edge forward of the island, the port waist catapult was removed, the crew spaces were refurbished, and all of the four remaining anti-aircraft turrets were removed. ''Roosevelt'' set sail with 4 - 5" guns, 2 on either side controlled by 3 Mk 56 Gunfire control systems and one Mk 37 System. ''Roosevelt'' also received a deck edge spray system using the new seawater compatible fire-fighting chemical, Light Water. She put to sea again on 26 May 1969.

1970s

By the 1970s, ''Franklin D. Roosevelt'' and ''Coral Sea'' were showing their age. All three retained the McDonnell Douglas F-4 Phantom II in their air wings, being too small to operate the new Grumman F-14 Tomcat fleet defense fighter or the S-3 Viking anti-submarine jet. In 1977, ''Franklin D. Roosevelt'' was decommissioned as she was the least modernized and in poor condition compared to the others in her class. On her final deployment, ''Roosevelt'' embarked AV-8 Harrier jump jets to test the concept of including VSTOL aircraft in a carrier air wing.

1980s

''Coral Sea'' was rescued from imminent decommissioning by the election of Ronald Reagan as president of the United States in 1980. Reagan's proposed 600-ship Navy gave the remaining ships a new lease on life. ''Coral Sea'' underwent extensive refits to address the ship's poor condition.

When the McDonnell Douglas F/A-18 Hornet became operational in the mid-1980s, the Navy quickly deployed them to the ''Midway'' and ''Coral Sea'' to replace the older F-4s. On 15 April 1986, aircraft from ''Coral Sea'', as well as USAF F-111Fs from RAF Lakenheath in the UK, struck targets in Libya as part of "Operation El Dorado Canyon". The Hornets went into action for the first time, flying several ship-to-shore air strikes against Libyan shore installations that were harassing the fleet. During this action, the Hornets from ''Coral Sea'' attacked and destroyed the SA-5 missile site at Sirte which had been "painting" US aircraft with its radars. This was the combat debut for the Hornet, and incidentally marked the first combat use of the AGM-88 HARM anti-radiation missile. The Hornets attacked the SAM sites in bad weather and at wave top heights. All of them returned without mishap.

A 1986 refit for ''Midway'' removed her 6" armor belt and bulged her hull to try to increase freeboard. While successful in this regard, the bulges also resulted in a dangerously fast rolling period that prevented ''Midway'' from operating aircraft in heavy seas. The bulging was therefore not repeated on ''Coral Sea''.

1990s

The Reagan era reprieve could not last. In 1990, ''Coral Sea'', which had long since earned the nickname "Ageless Warrior", was decommissioned. ''Midway'' had one last war in which to participate, and was one of the six aircraft carriers deployed by the U.S. against Iraq during Operation Desert Storm.AR 600-8-27 p. 26 paragraph 9–14, p. 28 paragraph 2–14 A few months after the campaign, ''Midway'' was decommissioned.

''Coral Sea'' was slowly scrapped at Baltimore as legal and environmental troubles continually delayed her fate. ''Midway'' spent five years in the mothball fleet at Bremerton, Washington before being taken over by a museum group. The ship is now open to the public at the USS ''Midway'' Museum in San Diego, California.
