The Hyūga-class helicopter destroyer (ひゅうが型護衛艦, Hyūga-gata-goei-kan) are a type of helicopter carrier being built for the Japan Maritime Self-Defense Force (JMSDF).[1][2] Two ships of the class were built to replace the two 7,000-ton Haruna-class helicopter destroyers. The new ships are the largest combatant ship operated by Japan since the Imperial Japanese Navy was superseded by the JMSDF.[1] The first ship in the class, Hyūga, was commissioned on March 18, 2009 and stationed in Yokosuka, near Tokyo.[3] The second ship Ise went into service on March 16, 2011 and will be stationed in Kure.
The Hyūga-class' specifications are comparable to light aircraft carriers, such as Italian Giuseppe Garibaldi, Spanish Principe de Asturias and Royal Navy's Invincible-class carriers.[4] Under the JMSDF's naming conventions, the ships are called Goei-kan (護衛艦, lit. escort ship) in Japanese and destroyer in English, as same as other all the combatant ships of JMSDF.
According to a PBS documentary, JS Hyūga is the "first Japanese aircraft carrier built since WWII."[5]
The Hyuga 's code-name (16DDH) and Ise 's code-name (18DDH) derive from the Japanese calendar, specifically the 16th year and 18th year of the Heisei reign (2004 and 2006), when the provisional title was given.[1]
Design and specifications
The ships' primary mission is the anti-submarine warfare by her SH-60K anti-submarine helicopters. They also have enhanced command-and-control capabilities, allowing them to serve as flagships for the JMSDF.[1] During peacetime operations, or “military operations other than war” (MOOTW), the ships join the Osumi-class ships for peacekeeping and relief operations, as well as the “diverse situations” Japan foresees confronting on the high seas."[6]
The ships are able to carry up to eleven helicopters, relying on a 16-cell VLS carrying the ESSM SAM, along with the Phalanx CIWS, for self-defense. They are also equipped with the ATECS command system and FCS-3 phased-array radar system.[1]
Japan plans to build a new 22DDH helicoptor carrier, which is larger than the Hyuuga class. The new 22DDH will replace the Shirane class helicopter destroyer, which was scheduled to be decommissioned in FY2014.
Many media speculated the Hyuuga class ships would be outfitted with fixed-wing aircrafts, such as Harriers and F-35 Lightning II[7][8][9][1][10].
Ships in the class
Construction of the first ship Hyūga was started in 2006 and launched on 23 August 2007. The second was launched and named Ise on 21 August 2009.[11]
In November 2009, Hyuga participated in Annualex 21G joint naval exercise with USS George Washington (CVN-73) and other USN and JMSDF ships to maintain the interoperability between the two navies.
On 11 March, 2011, the 2011 Tōhoku earthquake and tsunami struck the northeast part of Japan. Hyuga immediately moved to off the coast of Miyagi prefecture and started search and rescue operation.[12] Ise, who went into service on 16 March, also will join aid delivery operation for refuge shelters.

|---|---|---|---|---|---|
| DDH-181 | Hyūga (16DDH) | 11 May 2006 | 23 August 2007 | 18 March 2009 | Yokosuka |
| DDH-182 | Ise (18DDH) | 30 May 2008 | 21 August 2009 | 16 March 2011 | Kure |
Name
The lead ship was named after Hyūga Province (日向国, Hyūga no kuni), present-day Miyazaki Prefecture, on the east coast of Kyūshū, inheriting the name of the Ise-class battleship Hyūga of the Imperial Japanese Navy, which was commissioned in 1918, and subsequently served in World War II. The second ship of the class was named after Ise Province (伊勢国, Ise no kuni), present-day Mie Prefecture, inheriting the name of the Ise-class battleship Ise. Following the Battle of Midway, the Hyuga and Ise were converted into a hybrid battleship/aircraft carriers in 1943. The aft gun turrets and barbettes were replaced by a small flight deck and hangar deck that could launch a squadron of Yokosuka D4Y dive-bombers and Aichi E16A seaplanes.[4]
