USS Coral Sea (CV/CVB/CVA-43), a Midway-class aircraft carrier, was the third ship of the United States Navy to be named for the Battle of the Coral Sea. She earned the affectionate nickname "Ageless Warrior" through her long career. Initially classified as an aircraft carrier with hull classification symbol CV-43, the contract to build the ship was awarded to Newport News Shipbuilding of Newport News, Virginia on 14 June 1943. She was reclassified as a "Large Aircraft Carrier" with hull classification symbol CVB-43 on 15 July 1943. Her keel was laid down on 10 July 1944 in Shipway 10. She was launched on 2 April 1946 sponsored by Mrs. Thomas C. Kinkaid and commissioned on 1 October 1947 with Captain A.P. Storrs III in command.

Before 8 May 1945, the aircraft carrier CVB-42 had been known as USS Coral Sea; after that date, CVB-42 was renamed in honor of Franklin D. Roosevelt, the late President, and CVB-43 was named the Coral Sea.

Coral Sea was one of the last U.S Navy carriers to be completed with a straight flight deck, with an angled flight deck added on during later modernizations. All subsequent newly-built U.S Navy carriers have had the angled deck included as part of the ship's construction. 

Vietnam and operations in the 1960s to early 1970s[edit]

Installation of the Pilot Landing Aid Television (PLAT) system was completed on Coral Sea on 14 December 1961. She was the first carrier to have this system installed for operations use. Designed to provide a videotape of every landing, the system proved useful for instructional purposes and in the analysis of landing accidents, thereby making it an invaluable tool in the promotion of safety. By 1963, all attack carriers had been equipped with PLAT and plans were underway for installation in the CVSs and at shore stations.

Following the Gulf of Tonkin incident in August, Coral Sea departed on 7 December 1964 for duty with the Seventh Fleet. On 7 February 1965, her aircraft, along with those from Ranger and Hancock, blasted the military barracks and staging areas near Đồng Hới in the southern sector of North Vietnam. The raids were in retaliation for a damaging Viet Cong attack on installations around Pleiku in South Vietnam. On 26 March, the Seventh Fleet units began their participation in Operation Rolling Thunder, a systematic bombing of military targets throughout North Vietnam. Pilots from Coral Sea struck island and coastal radar stations in the vicinity of Vinh. Coral Sea remained on deployment until returning home on 1 November 1965.

Coral Sea made another Westpac/Vietnam deployment from 29 July 1966 to 23 February 1967.

In the summer of 1967, the city of San Francisco adopted the ship as "San Francisco's Own." This might seem ironic given the strong anti-military sentiment in the San Francisco Bay Area, and the fact that this occurred during the Summer of Love. Despite this, the city and the ship enjoyed a formal, official relationship. However, there were probably many times the crew did not enjoy the attitudes of Bay Area residents at all. The feeling was mutual. In July 1968, prior to a deployment to Vietnam, Coral Sea participated in the carrier trials of the US Navy's proposed new interceptor, the General Dynamics–Grumman F-111B.

The ship continued to make WestPac/Vietnam deployments until 1975: 26 July 1967 to 6 April 1968; 7 September 1968 to 15 April 1969; 23 September 1969 to 1 July 1970; 12 November 1971 to 17 July 1972; 9 March 1973 to 8 November; and from 5 December 1974 to 2 July 1975. Operations by theUnited States Navy and the United States Marine Corps aircraft in Vietnam expanded significantly throughout April 1972 with a total of 4,833 Navy sorties in the south and 1,250 in the north. Coral Sea, along with Hancock, was on Yankee Station when the North Vietnamese spring offensive began. They were joined in early April by Kitty Hawk and Constellation. On 16 April 1972, their aircraft flew 57 sorties in the Haiphong area in support of U.S. Air Force B-52 Stratofortress strikes on the Haiphong petroleum products storage area in an operation known as Freedom Porch.

After refitting, from 1970 through to 1971, and during refresher training (REFTRA) down to San Diego, Coral Sea on her return trip to Alameda caught fire in the communications department. The fire spread so fast that Captain William H. Harris commanded that the carrier is placed just offshore between San Mateo and Santa Barbara in order to abandon ship if the fire could not be put under control. Several communications personnel were trapped and Radiomen Bob Bilbo and Bill Larimore pulled many shipmates out of the burning and smoke-filled compartments.L/Cpl Thomas P Howard Jr. of ships Mar/Det received a "Meritorious Mast" from Captain Harris as a result of his location and rescue of shipmates overcome by toxic smoke in security weapon space. An OBA was L/Cpl Howard's only breathing protection at the time.

Operation Pocket Money, the mining campaign against principal North Vietnamese ports, was launched 9 May 1972. Early that morning, an EC-121 aircraft took off from Da Nang airfield to provide support for the mining operation. A short time later, Kitty Hawk launched 17 ordnance-delivering sorties against the Nam Định railroad siding as a diversionary air tactic. Poor weather, however, forced the planes to divert to secondary targets at Thanh and Phu Qui. Coral Sea launched three A-6A Intruders and six A-7E Corsair II aircraft loaded with naval mines and one EKA-3B Skywarrior in support of the mining operation directed against the outer approaches to Haiphong Harbor. The mining aircraft departed the vicinity of Coral Sea timed to execute the mining at precisely 09:00 local time to coincide with President Richard M. Nixon's public announcement in Washington that naval mines had been seeded. The Intruder flight led by the CAG, Commander Roger E. Sheets, was composed of United States Marine Corps aircraft from VMA-224 and headed for the inner channel. The Corsairs, led by Commander Leonard E. Giuliani and made up of aircraft from VA-94 and VA-22, were designated to mine the outer segment of the channel. Each aircraft carried four MK52-2 mines. Captain William R. Carr, USMC, the bombardier/navigator in the lead plane, established the critical attack azimuth and timed thenaval mine releases. The first mine was dropped at 08:59 and the last of the field of 36 mines at 09:01. Twelve mines were placed in the inner harbor and the remaining 24 in the outer. All mines were set with 72-hour arming delays, thus permitting merchant ships time for departure or a change in destination consistent with the President's public warning. It was the beginning of a mining campaign that planted over 11,000 MK36 type destructor and 108 special Mk 52-2 mines over the next eight months. It is considered to have played a significant role in bringing about an eventual peace arrangement, particularly since it so hampered the enemy's ability to continue receiving war supplies.
