JS Kaga

JS Kaga (DDH-184) is a helicopter carrier of the Japan Maritime Self-Defense Force (JMSDF). Officially classified as a multi-purpose operation destroyer, she is the second ship in the Izumo-class aircraft carrier, the other being JS Izumo. Her namesake arises from Kaga Province (加賀国) in present-day Ishikawa Prefecture.

The ship bears the same name as the World War II-era JAPANESE AIRCRAFT CARRIER Kaga, the Tosa-class battleship turned aircraft carrier that was produced in 1928 and participated in the attack on Pearl Harbor. She is also slightly longer than her World War II predecessor. Kaga and Izumo are the first aircraft carriers built by Japan since the end of World War II. Kaga was built as part of a wider Japanese military buildup, triggered by heightened Sino-Japanese tensions regarding the contested ownership of the Senkaku Islands.

The JS Kaga is currently being upgraded into a fixed-wing carrier, capable of operate VTOL aircraft such as the F-35B.

Construction
Kaga was intended to replace the aging Shirane-class destroyer JDS Kurama, based on the schedule outlined within the 23 Mid-term Defence Capability Maintenance Plan to construct a 19,500-ton helicopter destroyer. Construction began at the Yokohama plant of Japan Marine United on 7 October 2013, and the ship was launched on 27 August 2015, with the commissioning on 22 March 2017. Construction of the ship cost.

Characteristics
The ship can host up to 28 aircraft, or 14 helicopters. Japanese nomenclature called Kaga a "multi-purpose operation destroyer" and its main purpose in the past was destroying enemy submarines. Despite this, only 7 anti-submarine warfare helicopters and 2 search and rescue helicopters were planned for the initial aircraft complement. 400 troops and 50 3.5-ton trucks (or equivalent equipment) can also be carried.

Kaga's flight deck has five helicopter landing spots that allow for simultaneous landings or take-offs. Like the Izumo, Kaga features no ski-jump ramp for aircraft takeoff, instead using a long flat flight deck, in a similar manner to the US Wasp-class amphibious assault ship-class and America-class amphibious assault ship amphibious assault ships.

Modifications
In 2010, Forecast International reported that it looked like some original design features were intended to support fixed-wing aircraft such as the Bell-Boeing V-22 Osprey and Lockheed Martin F-35 Lightning II; as of 2019 both Kaga and Izumo are scheduled to be refit to accommodate the F-35B STOVL variant during their sequential overhauls which will take five-years starting in 2022. Kaga's reconstruction was speculated to begin as early as 2021.

Kaga began her initial modifications in March 2022 at the Japan Marine United (JMU) shipyard in Kure, Hiroshima Prefecture. The proposed modification of Kaga will be more extensive than for her sister ship (and significantly more expensive) and includes changes to the shape of the bow. The initial modification of Kaga was completed in early 2024 and is to be followed by a second modification to the ship's interior, which is expected to begin in late 2026 and be completed by the end of Fiscal Year 2027.

Aircraft carried
In 2019, it was reported that Prime Minister Shinzo Abe approved a five-year defense budget, which included the upgrade of Izumo and Kaga and the purchase of a combined 147 F-35A and F-35B stealth fighters.

According to the newspaper Mainichi Shimbun, the Japan Air Self-Defense Force (JASDF) is planning to acquire a total of 42 F-35B variants: introducing 18 by FY2023, six in FY2024 and two in FY2025. This first batch are to be formed into a single squadron consisting of about 20 aircraft. Japan's Defense Minister, Nobuo Kishi, announced that Nyutabaru Air Base in Miyazaki Prefecture, Kyushu will host the F-35Bs. The base is located near the Southwest Islands, including Okinawa, and JMSDF's Kure Base in Hiroshima Prefecture, which is Kaga's home port.

Size
Kaga is 814 ft long and displaces 27,000 tons, making her the largest ship in the Japan Maritime Self-Defense Force. She is in the category of light carriers, such as Italy's Cavour, and sized similar to many nations' dedicated amphibious ships. She is considerably smaller than 'super' aircraft carriers – the USS George H.W. Bush, for instance, is 1,092 ft long and over 100,000 tons.

Air-defense
The ship is equipped with two Phalanx CiWS (close-in weapon systems) and two SeaRAM CiWS for her defense.

History
Kaga toured the South China Sea and the Indian Ocean during the Indo Southeast Asia Deployment (ISEAD) exercise in 2018 to bolster Japan's presence in geostrategic waters, eventually sailing to the Philippines, Singapore, Indonesia, India and Sri Lanka.

During a state visit to Japan in May 2019, Donald Trump visited Kaga in Yokosuka. During his visit, Trump made a speech in which he claimed that many of the United States's allies were taking advantage of its high defense budget by not spending enough on their militaries. Trump congratulated Japan for "...being a good ally and buying American...", and wished them success in the coming Reiwa Era.

In popular culture
Kaga's mascot is the personification of her World War II-era predecessor in Kantai Collection, where she is one of the most popular characters of the franchise. It began when Kadokawa Games shared official art on Twitter, depicting 1928 Kaga's Kantai Collection counterpart holding a scale model of the new Kaga the day after she was launched. It then continued when Kaga participated in the Indo Southeast Asia Deployment (ISEAD) exercise in 2018. Upon her return to Kure, Kantai Collection provided new art of their personification of Kaga wearing the new ship's insignia, with her rigging updated to match that of the new ship and featuring helicopters instead of World War II aircraft.
