Commissioned 25 March, 2015, JS Izumo (DDH-183) is one of the two largest ships in the Japanese Maritime Self Defense Force, along with her sister Kaga. A "mere" 48 feet shorter than the Yamato-class battleships, Izumo is nearly 200 feet longer than her predecessors, the Hyuga-class helicopter destroyers. Originally completed as a helicopter destroyer, with no catapults, Izumo was limited to her helicopters for an air wing. However, in 2018, it was announced that Izumo would be converted to allow her to operate fixed wing aircraft. The first stage was carried out in 2020, strengthening the heat-resistance of the flight deck, and improving power handling. The second stage is set to take place in 2024, and will include reshaping the bow. In October, 2021, Izumo conducted her first operations with the F-35B, using aircraft from the US Marine Corps.

Bonus Information

Fun Fact: With her conversion, Izumo is the first aircraft carrier operated by the Japanese since the end of World War II. Until the conversion, they had been interpreted as banned under the post-War Japanese constitution, which severely limited the offensive capabilities of the Japanese Self Defense Forces.
