CVX-class aircraft carrier

The CVX (formerly known as LPX-II, Hangul: 대형수송함-II) is a class of aircraft carriers proposed for the Republic of Korea Navy. The class is follow-on from the previous Dokdo-class amphibious assault ships which prioritized amphibious capability, while the CVX will be designed for fixed wing and rotary wing operations instead, constituting a traditional aircraft carrier. The planned development of the class was formally announced and funded as part of the 2020~2024 Mid-Term Defense Plan (국방중기계획), published in December 2020. The Korean presidential administration that entered power in 2022 is not supportive of the CVX project, and it was not funded in the 2023 and 2024 defense budgets.

Background
The introduction of the CVX into service is a continuation of the development of a blue water navy by the Republic of Korea Navy, a process begun in 2001. Thus far the program has consisted of the Dokdo-class amphibious assault ships, the Sejong the Great-class destroyer (KDX-III), Chungmugong Yi Sun-sin-class destroyer, and Gwanggaeto the Great-class destroyer destroyers, the Incheon-class frigates and Type 214 submarines.

The development of the blue water navy reflects the geopolitical circumstances that South Korea faces. At present, its two closest neighbors (China and Japan) are in the process of developing full aircraft carrier capability for their respective navies. The Japanese Maritime Self Defence Force (JMSDF) operates the Hyūga-class helicopter destroyer helicopter carriers and Izumo-class helicopter destroyer multi-purpose operation destroyers (de facto aircraft carriers) while the People's Liberation Army Navy currently operates the carriers Liaoning (Type 001) and Shandong (Type 002) and plans to commission the Fujian (Type 003) in 2023.

Development
In late 2020, design and acquisition work on the CVX class was sped up in the hope of countering naval expansions in South Korea's neighbors. This move is expected to bring forward the aircraft carrier's future in-service date by one year, and will require a hastened procurement process for the F-35B fighter jets that the warship will carry. , work on the CVX was intended begin in 2022 and end in 2030.

On the occasion of the MADEX trade fair in South Korea in June 2021, the Italian Fincantieri signed a contract with Daewoo Shipbuilding & Marine Engineering (DSME) for assistance in the design of the CVX. The South Koreans were seeking the support of an industrialist with experience in this field.

The administration led by President Yoon Suk Yeol, who was elected in 2022, is sceptical of the CVX project. The project received no funding in the Korean defence budgets for 2023 and 2024. While it is included in the Mid-term Defense Blueprint covering the period 2024-2028 that was released in December 2023, this document notes that it will be subject to the results of further research.

Specifications
Unlike the preceding Dokdo class, the CVX will not feature a well deck for amphibious assault craft. Instead, internal space will be dedicated to aircraft storage and maintenance. The flight deck will be of an axial design rather than using a ski-jump (used by other F-35B jet aircraft operators except for the United States Navy).

The CVX will be one of the few aircraft carriers in the world to feature two islands. The UK defense corporation Babcock International has been providing support to the CVX program and is a possible explanation for the twin-island design as Babcock led the development of the Queen Elizabeth-class aircraft carrier aircraft carrier program for the Royal Navy.

The Republic of Korea government has stated that the sensor and weapons fit for the CVX will be developed domestically and the ship will feature a multi-function radar (MFR) for ballistic missile defence (BMD). The same system will be used about the next generation KDDX-class destroyer

Aviation
The CVX would be the first class of aircraft carriers in the Republic of Korea Navy, in contrast to the Dokdo class of amphibious assault ships which have features such as a well deck to accommodate amphibious assault vehicles. The ship will make use of an axial flight deck similar to those used by the Tarawa-class amphibious assault ship, Wasp-class amphibious assault ship and America-class amphibious assault ship amphibious assault ships of the United States Navy. The Ministry of National Defense stated in August 2020 that twenty F-35Bs would be procured for the CVX. In terms of rotary wing aviation, the ship will accommodate the future Marine Attack Helicopters (based on MUH-1 Marineon) of the ROK Marine Corps.

In September 2022 the Korean Ministry of National Defence announced that 20 additional F-35As would be purchased for the ROKAF in place of the previously intended purchase of F-35Bs that were to have operated from the CVX. At this time Korea Aerospace Industries was offering to develop a navalised version of the KAI KF-21 Boramae to operate from the CVX.
