USS Enterprise (CVN-65)

USS ''Enterprise'' (CVN-65), formerly CVA(N)-65, is a decommissioned United States Navy aircraft carrier. She was the first nuclear-powered aircraft carrier and the eighth United States naval vessel to bear the name. Like her predecessor of World War II fame, she is nicknamed "Big E". At , she is the longest naval vessel ever built. ''Enterprise'' is the only ship of a class that was originally planned to have five other ships. Her displacement ranks her class as the third-heaviest carrier class, after the and the ''Gerald R. Ford'' class. ''Enterprise'' had a crew of some 4,600 service members.

''Enterprise'' was, at the time of inactivation, the third-oldest commissioned vessel in the United States Navy after the wooden- hulled and . She was inactivated on 1 December 2012, and officially decommissioned on 3 February 2017, after over 55 years of service."World's First Nuclear-powered Aircraft Carrier, the Big E, makes final voyage"

The name has been adopted by the future .

Design

Designed under project SCB 160, ''Enterprise'' was intended as the first of a class of six carriers, but massive increases in construction costs led to the remaining vessels being cancelled.

''Enterprise'' is the only aircraft carrier to house more than two nuclear reactors, having an eight-reactor propulsion design, with each A2W reactor taking the place of one of the conventional boilers in earlier constructions. She is the only carrier with four rudders, two more than other classes, and features a more cruiser-like hull.

Armament

Because of the huge cost of her construction, ''Enterprise'' was launched and commissioned without the planned RIM-2 Terrier missile launchers. Initially, the carrier had little defensive armament. Late in 1967, ''Enterprise'' was fitted with a prototype Basic Point Defense Missile System (BPDMS) installation, with two eight-round box launchers for Sea Sparrow missiles. A third BPDMS launcher was fitted during the ship's refit in 1970–1971.

Later upgrades added two NATO Sea Sparrow (NSSM) and three Mk 15 Phalanx CIWS gun mounts. One CIWS mount was later removed and two 21-cell RIM-116 Rolling Airframe Missile launchers were added.

Radar

''Enterprise'' had a phased array radar system known as SCANFAR. SCANFAR was intended to be better at tracking multiple airborne targets than conventional rotating antenna radars. SCANFAR consisted of two radars, the AN/SPS-32 and the AN/SPS-33. The AN/SPS-32 was a long-range air search and target acquisition radar developed by Hughes for the U.S. Navy. The AN/SPS-32 operated together with the AN/SPS-33, which was the square array used for 3D tracking, into one system. It was installed on only two vessels, ''Enterprise'' and the cruiser , placing a massive power drain on the ship's electric system.

The technology of the AN/SPS-32 was based on vacuum tubes and the system required constant repairs. The SPS-32 was a phased array radar which had a range of 400 nautical miles against large targets, and 200 nautical miles against small, fighter-size targets. These early phased arrays, replaced around 1980, were responsible for the distinctive square-looking island.

The AN/SPS-32 and AN/SPS-33 radars, while ahead of their time, suffered from issues relating to the electrical beam steering mechanism and were not pursued in further ship classes. While they are considered to be an early form of "phased array" radar, it would take the later technology of the Aegis phased array AN/SPY-1 with its electronically controlled beam steering to make phased array radars both reliable and practical for the USN. The dome above the SCANFAR contained the unique electronic warfare suite, the Andrew Alford AA-8200 dipole antennas (which never acquired a military designation). The system consisted of six rows of antennae encircling the dome. The antennas in the upper two rows were encased in piping radomes as they were small and fragile.

History

Commissioning and trials

In 1958, ''Enterprise''s keel was laid at Newport News Shipbuilding and Drydock Company in Shipway 11. On 24 September 1960, the ship was launched, sponsored by Mrs. W. B. Franke, wife of the former Secretary of the Navy. On 25 November 1961, ''Enterprise'' was commissioned, with Captain Vincent P. de Poix, formerly of Fighting Squadron 6 on her predecessor, in command. On 12 January 1962, the ship made her maiden voyage starting an extensive shakedown cruise and a lengthy series of tests and training exercises designed to determine the full capabilities of the nuclear powered super carrier. On 20 February 1962, ''Enterprise'' was a tracking and measuring station for the flight of ''Friendship 7'', the Project Mercury space capsule in which Lieutenant Colonel John H. Glenn, Jr. made the first American orbital spaceflight. ''Enterprise'' completed shakedown activities at Naval Station Norfolk on 5 April 1962.

1960s

On 25 June 1962, ''Enterprise'' joined the 2nd Fleet on her initial operational deployment, carrying out training off the US East Coast, and took part in Exercise ''LantFlex 2-62'', a nuclear strike exercise, in conjunction with the carrier from 6–12 July. In August, the carrier joined the 6th Fleet in the Mediterranean Sea, returning to Norfolk, Virginia on 11 October 1962.

1962 Cuban Missile Crisis

In October 1962, ''Enterprise'' was dispatched to her first international crisis. Following revelations that the Soviet Union was constructing nuclear missile launch sites on Cuba, President John F. Kennedy ordered the United States Department of Defense to conduct a large-scale buildup. Among the preparations, the U.S. Atlantic Fleet readied large numbers of its ships. On 22 October, President Kennedy ordered a naval and air "quarantine" (blockade) on shipment of offensive military equipment to Cuba, and demanded the Soviets dismantle the missile sites there. Five Second Fleet carriers participated in the blockade—''Enterprise'' (as part of Task Force 135), , , , and , backed by shore-based aircraft. By 28 October, the crisis was averted, after the United States secretly agreed to remove nuclear missiles from Italy and Turkey.

Second and third deployments

On 19 December 1962, a Grumman E-2 Hawkeye was catapulted off ''Enterprise'' in the first shipboard test of a nose-wheel launch bar designed to replace the catapult bridle. Minutes later, a second launch with a launch bar was made by a Grumman A-6A Intruder, demonstrating one of the primary design goals of reducing launch intervals.

In 1963–1964, now under command of Captain Frederick H. Michaelis, ''Enterprise'' made her second and third deployments to the Mediterranean. During her third deployment, the carrier was part of Operation Sea Orbit, the world's first nuclear-powered task force with the cruisers ''Long Beach'' and , together forming a convoy to sail around the world. On 25 February 1964, a crewman of the Finnish merchant ship was injured in a fall while the ship was in the vicinity of Souda Bay, Greece. ''Enterprise'' answered her call for assistance. A surgeon was transferred to ''Verna Paulin'' by helicopter. In October 1964, ''Enterprise'' returned to Newport News Shipbuilding and Dry Dock Company for her first Refueling and Overhaul. During this refit, her eight nuclear reactors, which had powered ''Enterprise'' as she steamed over , were refuelled, two of her propeller shafts were replaced, and the ship's electronics were updated. ''Enterprise'' emerged from her refit on 22 June 1965.

Vietnam deployments

In November 1965, the Enterprise was transferred to the Seventh Fleet, home-ported at NAS Alameda, California. The following month, on 2 December, she became the first nuclear-powered ship to engage in combat when she launched aircraft against the Viet Cong near Biên Hòa City. The ship led Carrier Division Three, with ''Enterprise'' (redesignated CVAN-65), which had Carrier Air Wing Nine (CVW-9) aboard, ''Bainbridge''; ; and . ''Enterprise'' launched 125 sorties on the first day, unleashing of bombs and rockets on the enemy's supply lines. On 3 December, she set a record of 165 strike sorties in a single day.

In January 1966, the aircraft carrier was continuing operations as a unit of Task Force 77 in the Gulf of Tonkin, as the flagship of Rear Admiral Henry L. Miller, Commander Carrier Division Three. Under the command of Captain James L. Holloway III, she was carrying a complement of approximately 350 officers and 4,800 men. Four West coast squadrons of CVW-9, commanded by Commander F. T. Brown, were embarked; VF-92, under Commander E. A. Rawsthorne, and VF-96, under Commander R. D. Norman, flying F-4B Phantom IIs; VA-93 under Commander A. J. Monger, and VA-94, under Commander O. E. Krueger, flying A-4C Skyhawks. With these squadrons were three others based on the East Coast; VA-36, under Commander J. E. Marshall, VA-76, under Commander J. B. Linder, flying A-4C Skyhawks; and RVAH-7, under Commander K. Enny, flying RA-5C Vigilantes. Rear Admiral Miller was relieved as Commander Carrier Division Three by Rear Admiral T. J. Walker on 16 February 1966. During the change of command ceremony on the flight deck, Rear Admiral Miller praised the ship's performance in his farewell remarks, and presented air medals to more than 100 pilots and flight officers.

The ship tied up at Leyte Pier, U.S. Naval Base Subic Bay, on the evening of 8 December 1966. Loading of supplies for the first line period was started immediately. Rear Admiral Walter L Curtis, Jr, Commander Carrier Division Nine, brought his flag aboard. In company with , and , ''Enterprise'' sailed for Yankee Station on 15 December, and took up her position there three days later.

When ''Enterprise'' departed the Gulf of Tonkin on 20 June 1967, her pilots had flown more than 13,400 battle missions during 132 combat days of operations.(Enterprise Command History 1967, 29) As Vice Admiral Hyland stated in his congratulatory statement, "the entire Air Wing Nine has earned a resounding 'Well Done'." The carrier had steamed 67,630 miles in operations with the Seventh Fleet. She arrived in Subic Bay on 22 June and departed on 25 June for return to Alameda on 6 July 1967.

At Alameda, ''Enterprise'' began an overhaul. Captain Kent Lee relieved Captain James L. Holloway as commanding officer in ceremonies on 11 July 1967. Shipyard work was completed on 5 September 1967, and after completing sea trials on 7 September, ''Enterprise'' steamed south from San Francisco Bay to San Diego to reembark CVW-9 and get underway for refresher training off the California coast.

''Enterprise'' was visiting Sasebo, Japan in January 1968 when the US intelligence ship was seized by North Korea, and she served as flagship of TF 71 (Rear Admiral Epes), which had been formed in response and they operated near South Korean waters for almost a month, during Operation Formation Star. When diplomatic negotiations had defused tensions, ''Enterprise'' and her escorts were released to head south to Yankee Station on 16 February 1968. ''Enterprise'' returned to NAS Alameda on 18 July 1968, having completed 12,839 catapult launches, with 12,246 sorties—9,182 of them combat. After a short overhaul in Puget Sound Naval Shipyard from 29 July to 26 September, she returned to Alameda to prepare for another deployment to Vietnam.

1969 fire

During the morning of 14 January 1969, while being escorted by the destroyers and , a MK-32 Zuni rocket loaded on a parked F-4 Phantom exploded when ordnance cooked off after being overheated by an aircraft start unit. The explosion set off fires and additional explosions across the flight deck.

The fires were brought under control relatively quickly (when compared with previous carrier flight deck fires), but 27 sailors were killed and an additional 314 sailors were injured. The fire destroyed 15 aircraft, and the resulting damage forced ''Enterprise'' to put in for repairs at Pearl Harbor Naval Shipyard, Hawaii, primarily to repair the flight deck's armored plating. On 1 March 1969, repairs to the ship were completed and the ship proceeded on her scheduled western Pacific (WESTPAC) deployment to Vietnam and the Tonkin Gulf. These destinations would be delayed by events in the eastern Sea of Japan.

Korean operations

On 14 April 1969, tensions with North Korea flared again as a North Korean aircraft shot down a Lockheed EC-121 Warning Star that was on a reconnaissance patrol over the eastern Sea of Japan from its base at Atsugi, Japan. The entire 31-man crew was killed. The US responded by activating Task Force 71 (TF 71) to protect future such flights over those international waters. Initially, the Task Force was to comprise ''Enterprise'', , , and with a screen of cruisers and destroyers. ''Enterprise'' arrived on station with TF 71 in late April after completion of repairs. The ships for TF 71 came mostly from Southeast Asia duty. This deployment became one of the largest shows of force in the area since the Korean War.

1970s

In 1969–1970, ''Enterprise'' returned to Newport News Shipbuilding and went through an overhaul and her second refitting. In January 1971, she completed sea trials with newly designed nuclear reactor cores that contained enough energy for 10 years. On 11 June 1971 ''Enterprise'', with Captain Forrest S. Petersen now in command and Carrier Air Wing Fourteen (CVW-14) onboard, then departed for Vietnam again.

South and Southeast Asia

''Enterprise'', and launched a total of 2,001 strike sorties by 30 July 1971. Strike operations in July were disrupted when the carriers on station evaded three typhoons: Harriet, Kim and Jean. A slight increase in South Vietnam strike sorties occurred during the month. These were mainly visual strikes against enemy troop positions and in support of U.S. helicopter operations. From August–November 1971, ''Enterprise'' was in operations on Yankee Station.

In December 1971, Captain Ernest E. Tissot, Jr. assumed command, and ''Enterprise'' was deployed to the Bay of Bengal, during the Indo-Pakistani War of 1971 as a show of strength against India's naval blockade by INS ''Vikrant''. Later a Soviet Navy submarine was also trailing the U.S. task force. A confrontation was averted when ''Enterprise'' moved away from the Indian Ocean toward Southeast Asia. ''Enterprise'' completed its deployment on 12 february 1972.

''Enterprise'' returned to the South China Sea from 12 September 1972 with CVW-14 onboard. On 18 December 1972, the United States resumed bombing campaigns above the 20th parallel under the name Linebacker II. During Linebacker II operations, ''Enterprise'' and other carriers on station reseeded the mine fields in Haiphong harbor and conducted concentrated strikes against surface-to-air missile and anti-aircraft artillery sites, enemy army barracks, petroleum storage areas, Haiphong naval and shipyard areas, and railroad and truck stations. Navy tactical air attack sorties under Linebacker II were centered in the coastal areas around Hanoi and Haiphong. There were 705 Navy sorties in this area during Linebacker II. Between 18 and 22 December, the Navy conducted 119 Linebacker II strikes in North Vietnam, with the main limiting factor on airstrikes being bad weather. In December 1972, the North Vietnamese returned to the peace table and Linebacker II ended. In January 1973, the Vietnam cease-fire was announced and American carriers ceased all combat sorties into North and South Vietnam. From 28 January 1973, aircraft from ''Enterprise'' and ''Ranger'' flew 81 combat sorties against lines-of-communication targets in Laos. The corridor for overflights was between Huế and Da Nang in South Vietnam. These combat support sorties were flown in support of the Laotian government, which had requested this assistance. Laos had no relationship with the ceasefire in Vietnam. ''Enterprise'' completed its deployment on 12 June 1973.

Post-Vietnam

After the cease-fire in Vietnam in 1973, ''Enterprise'' proceeded to the Puget Sound Naval Shipyard, Bremerton, Washington, where the carrier was altered and refitted to support the Navy's newest fighter aircraft – the Grumman F-14 Tomcat. Two of four jet blast deflectors were enlarged to accommodate the Tomcat. The No. 4 propulsion shaft was replaced; it had been bent when its screw became fouled in a discarded arresting gear cable.

On 18 March 1974, the first operational Tomcats of VF-1 Wolfpack and VF-2 Bounty Hunters made their maiden takeoffs and landings from the carrier. In September 1974, ''Enterprise'' became the first carrier to deploy with the new fighter plane when she made her seventh WESTPAC deployment.

In February 1975, Typhoon Gervaise struck the island nation of Mauritius, and ''Enterprise'' was ordered to provide disaster relief. Arriving at Port Louis, carrier personnel spent more than 10,000 man-hours rendering such assistance as restoring water, power and telephone systems, clearing roads and debris, and providing helicopter, medical, food and drinkable water support to the stricken area.

Operation Frequent Wind

In April 1975, ''Enterprise'', ''Midway'', , and were deployed to waters off South Vietnam for possible evacuation contingencies as North Vietnam, in violation of the Paris Peace Accords, launched a conventional invasion of South Vietnam. On 29 April, Operation Frequent Wind was carried out by U.S. Navy and U.S. Marine Corps helicopters from the 7th Fleet. The Operation involved the evacuation of American citizens and "at-risk" Vietnamese from Saigon, the capital of South Vietnam under heavy attack from the invading forces of North Vietnam.

President Gerald Ford ordered helicopter evacuation when PAVN shelling forced the cessation of fixed-wing evacuation from Tan Son Nhut Airport. With fighter cover provided by carrier aircraft, the helicopters landed at the US Embassy, Saigon and the DAO Compound to pick up evacuees. The last helicopter lifted off the roof of the United States Embassy at 7:53 am, local time, on 30 April 1975 carrying the last 11 Marine Security Guards. During Operation Frequent Wind, aircraft from ''Enterprise'' flew 95 sorties. VF-1 and VF-2, flying from ''Enterprise'' made the first combat deployment of the F-14 Tomcat.

Eighth and ninth deployments

In July 1976, ''Enterprise'' began her eighth Western Pacific deployment. Beginning in October she took part in the ANZUS exercise 'Kangaroo II' with ships of the Australian and New Zealand Navies.

One of the ports visited was Hobart, Tasmania in November 1976. It had also been the first time an American ship anchored in the capital's harbor, Hobart, since the early 1920s. A beer with a picture of the ''Enterprise'' for its label was just one of the commemorations received by the renowned nuclear carrier.

In February 1977, Idi Amin, the President of Uganda, made derogatory remarks against the United States in public and Americans in Uganda were taken hostage. This was several months after the Israeli raid at Entebbe airport. ''Enterprise'' and her escort ships were scheduled to transit home after a seven-month deployment, but having just left Mombasa after a port call, were directed to remain in the area and operated off the east African coast for about one week. The ship's Marine detachment and air wing prepared for a possible mission to rescue and evacuate the Americans, but Amin eventually released all the hostages. The ships then steamed across the Indian Ocean at high speed to make a previously scheduled final port call at NAS Cubi Point in the Philippines before returning to NAS Alameda.

In 1978, ''Enterprise'' underwent her ninth Western Pacific deployment, including port calls in Hong Kong, Perth, Australia, and Singapore. In January 1979, the carrier sailed into Puget Sound Naval Shipyard for a comprehensive 36-month overhaul. This overhaul modified the ship's superstructure – removing the SCANFAR radars and the unique inverted cone-shaped top section, which was three stories high. During the lengthy overhaul, Navy and shipyard personnel referred to ''Enterprise'' as ''Building 65.''

1980s

In 1982, the carrier made her 10th WESTPAC deployment. In April 1983, ''Enterprise'' ran aground on a sandbar in San Francisco Bay while returning from deployment and remained stuck there for several hours. Coincidentally, George Takei, who played Mr. Sulu, helmsman of the fictional starship , was aboard at the time as a guest of the navy. Even though groundings and collisions are usually career-ending events for U.S. warship captains, the captain at the time, Robert J. Kelly, who had already been selected for promotion to commodore, eventually became a four-star admiral and Commander-in-Chief of the U.S. Pacific Fleet.

In 1985, the Enterprise began training for her 11th WESTPAC deployment. Late at night on 2 November 1985 with Captain Robert L. Leuschner, Jr. on the bridge, she struck Bishop Rock on the Cortes Bank during flight exercises, damaging the outer hull with a gash more than 100 feet in length and knocking out of one screw, a chip whose size was illustrated with a photograph of a Navy diver stretched out and reclining inside the notch. The cost of repairing the damage was $17 million, and Leuschner was relieved of command on 27 January 1986 as a result of the incident, by Captain Robert J. Spane.

In 1986, the carrier made her 12th WESTPAC deployment, leaving on 15 January 1986. She led Battle Group FOXTROT, including , , , , , , and . The Battle Group sailed directly for the Indian Ocean, with stops in Hawaii, Subic Bay, and Singapore. On 28 April 1986, ''Enterprise'' became the first nuclear-powered aircraft carrier to transit the Suez Canal. She went from the Red Sea to the Mediterranean to relieve ''Coral Sea'', on station with off the coast of Libya. ''Enterprise'' entered the Mediterranean to support "Operation El Dorado Canyon", the US bombing of Libya. It was the ship's first visit to the Mediterranean in more than 22 years. During the deployment, Rear Admiral J.T. Howe was relieved as Commander Cruiser-Destroyer Group 3 by Rear Admiral Paul David Miller.

In February 1988, ''Enterprise'' underwent her 13th deployment and was assigned to Operation Earnest Will, escorting reflagged Kuwaiti oil tankers in the Persian Gulf. On 14 April, another Earnest Will ship, , struck an Iranian mine in international waters. In response, the U.S. launched Operation Praying Mantis against Iranian targets, starting with two Iranian oil platforms that were being used as support bases for Iranian attacks on merchant shipping.
