K-CVA (Large Korean aircraft-Carrier)

K-CVA Large Carrier As of 2020 The South Korean Navy hoped that domestic aircraft carriers will enter service in 2033. South Korea has long been developing ocean-going navy and domestic aircraft carriers. They also have a strong shipbuilding industry that ranks first in the world. They can obtain the most advanced carrier-based aircraft, radar, ship electricity and armament in the United States and Europe without any threshold. System, but subject to the northern situation, the Korean Navy had to devote more resources to the development of light frigates such as FFX (Incheon-class, Daegu-class) and even offshore missile boats and gunboats.

The long-term military construction plan disclosed by South Korea has included the construction of a new type of amphibious assault ship code-named LPH-II. It is expected to be in service by 2030, with a displacement of 30,000 tons, a flight deck of 250 meters long, and a capacity of 16 F-35B, or 3,000 Marines and 20 armored vehicles, its three-dimensional landing capabilities far exceed two Dokdo-class, 16 F-35B means it is also a standard light aircraft carrier.

In June 2021, the 2021 International Maritime Defense Industry Exhibition (MADEX), one of the main naval exhibitions in the Asia Pacific area, Daewoo Shipbuilding & Marine Engineering (DSME) showcased cutting-edge maritime defense technologies such as Korean "light carrier" (CVX) with ski jump stand. It cannot escape notice that Japan is contemplating construction of a "new type of air escort ship" of genreally similar dimnetions, though with catapults rather than a ski ramp configuration.

The display model of the proposed aircraft carrier which had more than a little British tone, with yhe twin islands of the Royal Navy's Queen Elizabeth class. The Daewoo / Hyundai [recently merged] design also had an Italian flavor, including the twin island design of Fincantieri's Trieste LHD (Landing Helicopter Dock). The South Korean design shifted the islands aft and gave them an inverse cant for signature reduction rather than the overhang on the British design, though with both the forward presumably for ship operations, with the after island devoted to flight operations.

It was proposed to be 270 meters [878] long - versus 283m / 920 feet for the Royal Navy's Queen Elizabeth class CVF - 60 meters wide [versus 69-75m / 224-230-240 feet for the Royal Navy's Queen Elizabeth class CVF] and a displacement of 60,000 tons, about the same, despite the Korean's narrower beam. Both ships have two elevators, though the ROK vessel has one amidships between the islands and another towards the port stern, while the Royal Navy vessel has both to the starboard, fore and after of the after island.

Similar bow shapes used on different vessels may work for entirely different reasons. Balancing these conflicting needs lead to several interesting approaches in bow design. The Queen Elizabeth design featuers the currently fashionable bulbous bow, optimized for minimum calm water resistance below waterline. The forward rake increases the resistance to ship pitch motions. Bulbous bows on ships have been known for 70 years or more. These bow configurations were, and are being used, in order to decrease the resistance of the water to the travel of the ship. Decreasing the resistance of the water to the ship's travel reduces the energy required to propel the ship bring about a number of desired results. For one thing, the amount of fuel required for a given velocity or a given distance of travel is decreased. Secondly, the size and therefore the cost of the ship's propulsion equipment can be reduced to attain a given velocity. Alternatively, with the reduced resistance obtained as a result of a bulbous bow a ship with a given propulsion equipment can attain greater velocities. The Korean vessel features a rather retrograde design, reminicent of the vertical stem designs of early 20th century passenger vessels such as the Queen Mary.

On 10 June 2021, during MADEX Fincantieri signed a contract with Daewoo to support the Conceptual Design of the new class of aircraft carriers “CVX” for the Navy of the Republic of Korea. The program relating to the first-in-class unit envisages the tender for the Basic Design starting from the second half of 2021, whereas the detail design and construction will begin in the following years. Fincantieri will advise DSME based on the expertise gained with the construction of the 40,000 ton 245 meter “Trieste” LHD , slated for delivery in 2022 to the Italian Navy. Trough its subsidiary Seastema, the Group was already cooperating in the construction of eight new Daegu class frigates (FFX-II) for the South Korean Navy.

Generally, carriers are classified into large-sized ships of 70,000 tons or more, medium-sized ships of 40,000 to 70,000 tons, and light-type ships of less than 40,000 tons. US Gerald Ford (CVN-78), which was commissioned on July 23, 2017, is also a large carrier. The medium-sized carriers include the PA2 in France and the Queen Elizabeth in England. Japan's "Izumo", the largest maritime SDF warship in postwar Japan, is a light carrier.

Historically, Korea's attempt to introduce aircraft carriers have been frustrated several times. When the conflict with Japan over Dokdo in 1996 deepened, Kim Young-sam government promoted the introduction of air carriers. At that time, the work on air carriers was carried out secretly without knowing the Minister of National Defense. In October 1996, Hyundai Heavy Industries announced that it was planning to build an aircraft carrier for the Navy with the aim of commissioning in 2012. It was announced at the time of the release of a miniature carrier model with a length of 197m, a width of 24m and a displacement of 15,000 tons. However, in 1997, as Korea became involved in the turmoil of the East Asian financial crisis, the introduction of air carriers, which had a huge budget, was not promoted. After overcoming the tribulation, the company tried again to introduce the carrier, which increased by 35,000 tons, but it was canceled due to budget problems.

In 2013, Choi Yoon-hee, chairman of the Joint Chiefs of Staff, announced plans to review the necessity of securing aircraft carriers. At that time, the Navy had conducted an external research analysis on maintaining a light aircraft carrier due to the presence of aircraft carriers with China and Japan. At the time, the report said that it should secure at least two "special model landing ships" for the rapid protection and reclamation of maritime territories in case of emergency and to maximize strategic effect on neighboring countries. In this way, it was proposed to build the Dokdo # 2 ship at 20,000~30,000 tons displacement and to convert the existing Dokdo into a form capable of operating vertical takeoff and landing aircraft.

Kang Young-oh, the commander of Navy Education, wrote in a contribution to the "Monthly Chosun" written in November, 2013 (why the ROK Navy should secure nuclear carriers and nuclear submarines). "In general, the Navy itself is a weapon system that is too expensive to buy, and I know it is not appropriate for the Korean Navy to secure it. But this is a misperception. The land-based air force near the Seoul metropolitan area is worth more than KRW 25 trillion to build an air force base of 2.5 million pyeong (8.26 million 442 square meters) because it exceeds 10 million won per pyong (3.3 square meters). To build a new air force base, the land compensation cost is 3 ~ 5 trillion won and the airfield construction cost is 15 trillion won. But France's De Gaulle nuclear-powered cargo carrier costs about 2.5 trillion won.

"From the point of view of the availability of the air base, the front airports of Osan, Suwon, Seoul, and Gangwon are all within the 240 ~ 300mm radius of the DPRK and the guns. In particular, since it is the target of the North Korean air operations, the ROKAF will not be able to provide the defense and the offensive.

"It may be argued that the Korean Navy should try to build a conventional carrier without considering the nuclear drive because it is the first attempted carrier. However, the main advantage gained by nuclear propulsion is due to its ability to maneuver unlimited distances at high speeds without refueling. Moreover, there is a very significant additional benefit to the nuclear propulsion carrier (CVN). Nuclear propulsion carriers have sufficient margins to carry combat supplies, including oil in the escort and tankers, to the carrier, since there is no need to carry general fuel for propulsion. The Korean Navy is late compared to its neighboring countries, but if it launches nuclear-powered carriers, it will be the first to obtain the best nuclear-powered aircraft carriers in comparison with neighboring countries in Northeast Asia."

K-CVA Large Carrier The 2015 Naval Force Analysis Test Evaluation Team under the Park Hui administration has conducted research on domestic and international aircraft carrier construction to cope with North Korea's diversifying military threat and China-Japan aircraft carrier possession. The Naval Force Analysis and Evaluation Team commissioned the Daewoo Shipbuilding & Oceania Consortium to 'examine the possibility of building a next-generation aircraft carrier'. The study period was 8 months from April to November 2015. The report, "Study on possibility of construction of next-generation advanced warships" composed of 597 pages in total, was obtained by Chosun Ilbo ["Monthly Korea".

The core mission of the aircraft carrier was 'Strategic Paralysis Operation' and 'Deep Target Strike', which attack the main military facilities of North Korea in time of war. The aircraft carrier has to advance to the Tokai area or the open sea of the West Sea and bypass the northern operation area with a large amount of air-defense defense concentration. In order to succeed in the 'Pre-Paraplegic' campaign, North Korea should head north to the West Sea or the East Sea coast and serve as a forward base for North Korea's WMD and strategic weapons strikes. Yongbyon, where North Korea's nuclear facilities are concentrated, is only 50km away from the coastline of the West Sea, so it is easy to approach from the coast. The aircraft carrier would launch air raids with fighter planes from the sea. In case of emergency it must carry out a mission to launch a helicopter force carrying a special unit for the recovery of North Korea's weapons of mass destruction, including nuclear weapons.

It also has to carry out a large firefighting mission for long range artillery forces, the greatest threat to the metropolitan area. by one estimate there are about 340 long-range guns in North Korea located near the entire Seoul metropolitan area, and an aircraft carrier has to destroy about 110, which is about one-third of them. It must also carry out the SEAD (Suppression Enemy Air Defense) operation against SA-5 surface-to-air missiles around the Yellow Sea, which protect long range guns. By one estimate North Korea holds surface-to-air missiles such as 179 SA-2 units, 133 SA-3 units, and 38 SA-5 units, and forms an air defense network from low altitude to high altitude.

If China were to intervene in a crisis on the Korean Peninsula, the carrier also has the task of engaging Chinese fighters and supporting the formation of a defense. If China launches fighter aircraft from a naval air base in Shandong Peninsula, it takes only about 30 minutes to pass precision weapons to the west coast area after passing through the Korean Air Defense Identification Area (KADIZ).

If a territorial disputes arises with Japan, there was a requirement to interfere with the formation of Japanese attacking units by engaging fighter planes (2 ~ 4 units) or more.

The 2015 report concluded that in order to carry out these missions, the target carrier should be equipped with more than thirty (32) fighters. According to the report, when it comprehensively judged the nature of the mission, the required operational capability, the number of installed units, and the supporting facilities, it said that the alternative that can be met is a mid- to large-sized carrier with a displacement of 70,000 tons or more. In the case of overseas performance, it concluded the Queen Elizabeth of England and PA2 of France were closest to the character of the target carrier.

It takes at least 12 years and up to 17 years for development (2 ~ 3 years), exploration development (3 ~ 4 years), and system development (7 ~ 10 years). Even if a decision had been made to build a carrier in the year 2018, it would be completed in 2030 at the earliest and in 2035 at the latest.

The specifications of the domestic target aircraft carrier was modeled on PA2 and Queen Elizabeth in the 2015 report. The mounted aircraft included 32 F-35C class fixed wing units, and 8 hHelicopter. The flight deck would be inclined, with no restrictions on the types of aircraft that can be operated. The aircraft can be launched and recovered at the same time due to the use of the runways and wide flight decks, and the disadvantages are that the equipment is complicated. The report also set out plans for the construction of mid- and small-sized aircraft carriers, in case the budget issue continues to fall.

If a Korean aircraft carrier is built, will it take 5 trillion won to acquire a new installation aircraft and train several thousand new personnel. Skeptics argue that it would be cheaper to build a fortress-like air base on Jeju Island with that money. If ROK deployed F-35 there and deploy anti-ship missiles, ROK could counter China and Japan. China and Japan are advancing into the ocean and moving to complete aircraft carrier systems. Such mobile strength can be several times stronger than fixed strength. The carrier moves as needed, supports the fleet, and easily takes control of the sea from the enemy in a naval battle.

K-CVA Large Carrier A special "report" was disclosed on 10 October 2019 at a meeting of the National Defense Committee of the South Korean National Assembly. Lee Jae-sung, a member of the governing Democratic Party, asked to consider a proposal to promote the construction of a real aircraft carrier instead of an amphibious assault ship for the navy of the country. The reason is that the surrounding powers all have aircraft carriers.

The scheme named "Medium Carrier" is actually quite large, with a standard displacement of 53,692 tons and a full-load displacement of 71,400 tons, which is larger than the Liaoning ship of 65,000 tons, 298 meters long and 75 meters wide, which is larger than Kuznetsov The Liaoning and Liaoning ships are slightly shorter but wider. The carrier-based aircraft can carry 32 carrier-based fighters and 8 helicopters, with a crew of 1,340 (including 640 aviation personnel) and a construction cost of 5.4 trillion won (about 4.5 billion US dollars). , Using a stylish twin ship island layout.

The other solution, called "Light Carrier", is actually a standard medium-sized carrier. It is 238 meters long and 62 meters wide, with a standard displacement of 33,751 tons and a full-load displacement of 41,500 tons. It can carry 12 carrier-borne fighters and 8 helicopters, with a crew of 720 (including 320 aviation personnel). The estimated construction cost is 31,000. 100 million won (about 2.6 billion US dollars), it uses a more compact single ship island design, tonnage, specifications and the French Navy's "Charles de Gaulle".

It is worth mentioning that neither of the two types of aircraft carriers provided ski-jump take-off deck. The aircraft carrier assumption chart on the PPT also appeared with suspected catapults and arresting cables. This means that it is different from the new aircraft carriers in the UK and other countries. It is suggested that the promoters hope that South Korean domestic aircraft carriers will be "one step in place" and use conventional take-off and landing carrier fighters such as F-35C with better performance and longer range, rather than F-35B with vertical take-off and landing but shorter combat radius.
