Twelve, "Nimitz" class aircraft carrier

Nimitz class is the aircraft carrier with the largest displacement, the largest number of aircraft carriers and the highest degree of modernization in the world. It is also the second-generation nuclear-powered aircraft carrier in the United States after the "Enterprise" nuclear aircraft carrier. The first ship "Nimitz" was commissioned in 1975. The hull and deck of this class of ships are made of high-strength steel, which can resist the attack of semi-armor-piercing projectiles. The ammunition depot and engine room are equipped with Kevlar armor with a thickness of 63.5 mm, and there are 23 watertight transverse bulkheads and 10 fire-proof partitions in the ship, which have complete protective measures such as fire fighting, pipeline damage and impact resistance. It can withstand three times the impact of Essex-class aircraft carriers. It can carry out ocean-going operations to seize air and sea control, attack enemy targets at sea or on land, and support landing operations and anti-submarine.

At present, there are 8 ships in service and under construction 1 ship, which is included in the plan 1 ship and is the backbone of the US Navy's active aircraft carrier.

1. "Nimitz" CVN68 1968 was started, 1972 was launched, 1975 joined the Atlantic Fleet, 1987 was transferred to the Pacific Fleet, and its home port was in Bremerton. The ship has a standard displacement of 74,042 tons, a full-load displacement of 9 1.487 tons, a total length of 333 meters and a flight deck width of 76.8 meters. It is powered by two A4W pressurized water nuclear reactors, with 280,000 horsepower and a speed of over 30 knots. After replacing the nuclear fuel once, it can run continuously for 13 years, and its endurance can reach 800- 1 10,000. Nimitz adopts A4W nuclear reactor with higher power, better structure and longer service life, and is equipped with computer data processing system and sea sparrow ship-to-air missile, which can last for 50 years. 1September 5, 1997 to1February 28, 1998, the ship belonged to the Pacific Fleet and was equipped with the 9th carrier aviation wing. It departed from San Diego on the west coast of the United States, crossed the Pacific Ocean and the Indian Ocean, spent three months on duty in the hot Persian Gulf, participated in air strikes against Iraq, and then crossed the Red Sea, Suez Canal, Mediterranean Sea and Atlantic Ocean to reach the Mayport Naval Base on the east coast of the United States.

2. "Eisenhower" CVN69 is the second Nimitz-class ship, named after the 34th President of the United States. Its performance is the same as that of Nimitz. It was commissioned in 1977 and deployed in the Atlantic Fleet. Its home port is Norfolk Naval Base. It took part in the war in Bosnia and Herzegovina and made many trips to the Mediterranean and the Gulf. At present, it belongs to the Pacific Fleet and is equipped with the 7th carrier aviation wing and 80 aircraft of various types.

3. "Vinson" CVN70 was named after carl vinson, Chairman of the Armed Services Committee of the US House of Representatives, who was a staunch supporter of the navy before World War II. /kloc-0 joined the Atlantic fleet in March, 1982, and/kloc-0 was deployed to the Pacific fleet in March, 1983, and its home port was Bremerton Naval Base. The ship has been on duty in the Gulf for many times and participated in air strikes against Iraq. At present, under the command of the commander of the third aircraft carrier brigade, it is equipped with 1 1 carrier aviation wing and equipped with 78 aircraft of various types.

4. The full-load displacement of "Roosevelt" CVN7 1 increased to 97,574 tons, 1986 entered the service in June, and was deployed in the Atlantic Fleet, and its home port was Norfolk Naval Base. Participated in the Gulf War, participated in the Kosovo War from 65438 to 0999, and had the most practical experience in ships of the same class. At present, it is equipped with the 8th carrier-based aviation wing and 80 carrier-based aircraft of various types, which are escorted by 2 cruisers, 4 destroyers, 2 nuclear submarines and 1 fast combat support ships.

5. After loading 2,900 tons of aviation ammunition and 3.5 million gallons of aviation gasoline, Lincoln's CVN72 has a full displacement of102,000 tons, making it the first aircraft carrier in the world with a deadweight exceeding1000,000 tons. The ship entered service in 1989 and was first deployed in the Atlantic fleet. 1990 was handed over to the Pacific Fleet, and the home port was moved from Norfolk to Everett, Washington. At present, it is equipped with 14 carrier aviation wing, 78 aircraft of various types, 2 guided missile cruisers, 6 destroyers, 2 frigates, 3/KLOC-0 nuclear submarines and 3 logistics ships.

6. "Washington" CVN73 1992 is in service and deployed in the Atlantic Fleet, and its home port is Norfolk Naval Base. At present, it belongs to the 2nd Cruiser Destroyer Brigade, carrying the carrier-based aviation wing number 17, and equipped with 78 aircraft of various types, which are replenished and escorted by missile cruisers Normandy, destroyers Brisco and Cannon, frigates Simpson, nuclear submarines Annapolis and Albany, and fast combat support ships.

7. "Stannis" CVN74 1995 12 was appointed. It is the first modern aircraft carrier equipped with IT-21"21Century Information Technology" system in the US Navy, and its nuclear power plant has been further improved. After one-time injection of nuclear fuel, it can run continuously for 23 years and can be used in 45-20 years. After joining the active service, the ship was first deployed in the Atlantic Fleet, and/kloc-0 was transferred to the Pacific Fleet in August 1998. The home port was also transferred from Mayport to the naval base in San Diego. In the first half of 2000, the ship was equipped with 74 aircraft of various types of the ninth carrier aircraft aviation wing. The first voyage was to the western Pacific Ocean and the Persian Gulf for a six-month overseas mission.

8. "Truman" CVN75 1993 to 1996 was built, 1998 entered service in July, and was deployed in the Western Pacific Fleet with its home port in Norfolk. Under the command of the commander of the second aircraft carrier brigade, there are 74 aircraft carrying the third carrier aviation wing.

9.1The "Reagan" CVN76 Nurponius Shipyard, which started construction on February 9, 984, will replace the carrier constellation. It cost $4 billion.

The last Nimitz-class aircraft carrier CVN-77 was built by the US Navy, and the hull cost was about $380 million. It is expected to be put into use in 2008, replacing the existing Kitty Hawk (CV-63). This aircraft carrier, named after former US President George Bush Sr, hopes to become a bridge connecting the preceding with the following, accumulate experience for future US Navy aircraft carriers and provide an experimental platform. The US Navy began to design and develop a new generation of aircraft carrier CVNX in 1995. Design is a brand-new concept. In view of this, the US Navy decided to use the CVN-77 aircraft carrier as a "transitional" aircraft carrier to develop technologies related to CVNX-class aircraft carriers.

Thirteen, the current situation and future of American aircraft carriers

At present, the US Navy has 12 large aircraft carriers of Type 2 and Type 3, including 3 Kitty Hawk-class conventional power carriers, 1 enterprise-class nuclear-powered aircraft carriers and 8 Nimitz-class nuclear-powered aircraft carriers. Among them, except Kitty Hawk's home port is located in Yokosuka Naval Base, Japan, the home ports of other 1 1 ships are located in the five major aircraft carrier bases in the United States.

According to the US Navy, in peacetime, a standard training, duty and rest period for each aircraft carrier is 18 months, each accounting for13 of the time. Therefore, under normal circumstances, the US Navy currently has 12 aircraft carriers, of which 1/3 is on duty or undertaking combat missions in overseas frontier areas such as the Gulf, the Western Pacific and the Mediterranean, 1/3 is engaged in maritime training, and 1/3 is resting in the port or entering the factory for maintenance. Of course, the period of training, rest and maintenance in wartime will be shortened, and the number of aircraft carriers capable of carrying out combat missions will increase by 50% compared with usual, reaching 1 times, and 6-8 aircraft carriers may be assembled for combat. The current deployment is as follows:

Kitty Hawk (CV-63) and its home port of Yokosuga.

● Constellation (CV-64) and Stannis (CVN-74), the home port is San Diego, California, USA.

The home port of carl vinson (CVN-70) is Bremerton, Washington, USA.

● The home port of Lincoln (CVN-72) is Everett, Washington.

Atlantic fleet:

● Enterprise (CVN-65), Nimitz (CVN-68), Eisenhower (CVN-69), Roosevelt (CVN-7 1), Washington (CVN-73) and Truman (CVN-75), with their home ports in Norfolk, Virginia, USA.

● The Kennedy (CVN-67), whose home port is Mayport, Florida, USA (used as a training aircraft carrier when not performing tasks).

● Reagan: Not yet deployed.

Maintaining 12 large aircraft carrier formation is the minimum standard set by the US Department of Defense for "winning two almost simultaneous theater wars". 2/kloc-0 At the beginning of the century, the US Navy will continue to maintain this plan.

At the end of 2002, Reagan will replace the Kitty Hawk constellation. By 2008, 10 nimitz class carrier CVN77 will replace Kitty Hawk. The first CVNX class CVNX- 1 under study will start construction in 2006, which will be further improved on the basis of CVNX-77, and will replace Enterprise in 20 13 years. The second CVNX class aircraft carrier will replace Kennedy in 20 18. By then, all conventional aircraft carriers of the US Navy will be retired, and all aircraft carriers in the United States will be nuclear-powered.
