The Izumo class ( Japanese ず も 型 護衛艦 , Izumo-gata goeikan ), also known as the 22DDH class , is a class of two helicopter carriers of the Japanese Marine Self- Defense Forces (JMSDF). Constitutional reasons they are officially called " helicopter - Destroyer " (DDH, Jap. ヘリコプター搭載護衛艦 , herikoputā Tosai goeikan , the Japanese term for "destroyer" literally "escort ship" means), respectively. The code name 22DDH for the first unit comes from the Japanese calendar, where 2010 (year of construction) is the 22nd year of the Heisei period .
history
Development and construction
The Izumo , named after the historic province of Izumo , and her sister ship Kaga , named after the historic province of Kaga , replaced the two from the 1970s, originating helicopter destroyer of Shirane class , Shirane (DDH-143) and Kurama (DDH- 144). Since entering service, the Izumo has been the largest Japanese warship since World War II .
Both were at the shipyard of IHI Marine United in Yokohama built. The Izumo was laid down there on January 27, 2012 and was launched on August 6, 2013, in the presence of the Japanese Minister of Finance and Deputy Prime Minister Tarō Asō . The cost of its construction amounted to 1.2 billion US dollars . The keel of her sister ship was laid on October 7, 2013.
The Izumo entered service in Yokohama on March 25, 2015 and assigned to the 1st destroyer squadron. The second ship of the class, the Kaga , was commissioned on March 22, 2017.
Prime Minister Shinzō Abe announced in December 2018 that his government had approved the purchase of 105 Lockheed Martin F-35 fighter jets, 42 of which were STVOL F-35B variants . Since the latter are supposed to land and take off on ships of the Izumo class if required, the Izumo and Kaga will in fact be converted into aircraft carriers .
International response
On the part of the People's Republic of China , the construction of the class is seen as an "alarming signal of the rearmament of Japan". The name of the type ship ( Izumo ) was also perceived as a provocation , since the Izumo , an armored cruiser built in 1899, already existed, which was used by the Imperial Japanese Navy against China in the Second Sino-Japanese War . It was also suspected that the intention was to equip the ships with Lockheed Martin F-35 aircraft, which ultimately turned out to be correct. The completion of the Izumo could strengthen the military position of Japan in the dispute over the Senkaku Islands .
Again, the classification as a destroyer is only owed to Article 9 of the Japanese Constitution . This states that the self- defense forces may only be used for defense and humanitarian tasks . The official Japanese side emphasizes that, despite the similarity, it is not a helicopter or aircraft carrier, but a destroyer with flat superstructures.
The launch date also caused irritation, as August 6th is the annual and commemorative day of the atomic bombing on Hiroshima . According to Japanese sources, the overlapping of the dates should have been accidental.
On May 1, 2017, it was announced that the carrier had been sent to the Sea of Japan to protect the US carrier fleet there due to the tightening of relations between the USA and North Korea.

General
The helicopter carriers built in stealth design - the surfaces are kept as smooth as possible and right angles are avoided as far as possible - were primarily developed for submarine hunting . They are 248 meters long, 38 meters wide and with a maximum displacement of 27,000 tons have a draft of 7 meters.
You have the option of transporting fourteen helicopters. However, the regular equipment consists of seven submarine attack helicopters ( SH-60J / K ) and two multi-purpose helicopters ( CH-101 ). In addition, they can take on board STVOL aircraft such as the F-35B .
With a length of 248 meters, the size of the flight deck corresponds roughly to that of the significantly larger French aircraft carrier Charles de Gaulle (261.5 meters × 64 meters).
Armament and sensors
The armament has been reduced in contrast to the previous class . You only have two Phalanx-CIWS - and two SeaRAM - close-range defense systems .
For air traffic control is a AESA radar type OPS-50 (FCS-3) and a navigation radar , a OPS-28 is used. Furthermore, both ships will have an OQQ-23 bow sonar .
