In August 2015, a new subclass of the Atago-class destroyer, dubbed the 27DDG Destroyer, was announced. With an empty displacement of 8,200 tons, the new class is intended to be equipped with the Aegis combat system and also be equipped with Cooperative Engagement Capability (CEC) equipment, equivalent to that used on the United States Navy's Arleigh Burke-class Flight 2A:Restart guided missile destroyers which are capable of launching SM-3 block II anti-ballistic missiles. The ships propulsion system has been changed from COGAG from Atago-class to a COGLAG to improve fuel economy. The first two ships of the new class are expected to enter service in 2020 and 2021 respectively. [2]

Future armaments for the ships is slated to include locally built railgun and laser point-defense system.[3]


Being an improved subclass of the Atago-class destroyer, the Maya-class is very similar to its parent class but with several differences and improvements.

  1. While it shares the same design characteristics as the Atago-class, the Maya-class possesses a larger hull. The enlarged hull is believed to allow future naval weapons to be accommodated, most notably railguns and laser point-defense systems.
  2. The ships will be powered by a COGLAG propulsion system to improve the management and distribution of power in light of its future weapon accommodation.
  3. The Maya-class features the newer Aegis Baseline 9 system (referred as J7 in Japan). The Atago-class uses the Aegis Baseline 7 system.[4] The Maya-class is also the first JMSDF Aegis vessel to be ready for ballistic missile defense (BMD) from the time of its commissioning. The Atago-class and the older Kongō-class destroyer underwent modifications to be able to conduct BMD.[5]
  4. The Maya-class is equipped with the Cooperative Engagement Capability (CEC) system. This will allow the ship to share surveillance or targeting information between other CEC equipped assets, whether that be from ships from the American or Australian Navy or from American or Japanese E-2 Hawkeye.[5]
  5. The ships are equipped with the SM-3 Block IIA and SM-6 missiles.[6] The SM-3 Block IIA is the latest variant of the SM-3 missiles and is joint developed between the U.S. and Japan. The SM-6 missiles can be networked to the CEC system and thus allow it to receive targeting information from other CEC equipped sources. While the primary role of the SM-6 is to intercept enemy aircraft and cruise missiles, the SM-6 is also capable of intercepting medium-range ballistic missile and can double as an anti-ship missile. This gives the Maya-class more flexibility in handling threats than its predecessors.
  6. The ship will use a Type 17 Ship-to-Ship Missile.[5] The Type 17 missile is ship mounted version of the Type 12 Surface-to-Ship Missile and the Type 12 missile is an upgraded Type 88 Surface-to-Ship Missile, which in turn developed the Type 90 Ship-to-Ship Missile that the Atago-class uses.


Maya shares her name with the World War II era Japanese Takao-class heavy cruiser Maya,[7] while Haguro shares her name with Myoko-class heavy cruiser Haguro.[8]

Arleigh Burke-class destroyer

The Arleigh Burke class of guided missile destroyers (DDGs) is a United States Navy class of destroyer built around the Aegis Combat System and the SPY-1D multifunction passive electronically scanned array radar. The class is named for Admiral Arleigh Burke, an American destroyer officer in World War II, and later Chief of Naval Operations. The class leader, USS Arleigh Burke, was commissioned during Admiral Burke's lifetime.

These warships were designed as multimission destroyers, able to fulfill the strategic land strike role with Tomahawk missiles; antiaircraft warfare (AAW) role with powerful Aegis radar and surface-to-air missiles; antisubmarine warfare (ASW) with towed sonar array, anti-submarine rockets, and ASW helicopter; and antisurface warfare (ASuW) with Harpoon missile launcher. With upgrades to their AN/SPY-1 phased radar systems and their associated missile payloads as part of the Aegis Ballistic Missile Defense System, the ships of this class have also begun to demonstrate some promise as mobile antiballistic missile and anti-satellite weaponry platforms. Some versions of the class no longer have the towed sonar, or Harpoon missile launcher. Their hull and superstructure were designed to have a reduced radar cross-section.The first ship of the class was commissioned on 4 July 1991. With the decommissioning of the last Spruance-class destroyer, USS Cushing, on 21 September 2005, the Arleigh Burke-class ships became the U.S. Navy's only active destroyers, until the Zumwalt class became active in 2016. The Arleigh Burke class has the longest production run for any post-World War II U.S. Navy surface combatant. Besides the 62 vessels of this class (comprising 21 of Flight I, 7 of Flight II and 34 of Flight IIA) in service by 2016, up to a further 42 (of Flight III) have been envisioned.

With an overall length of 505 to 509 feet (154 to 155 m), displacement ranging from 8,315 to 9,200 tons, and weaponry including over 90 missiles, the Arleigh Burke class are larger and more heavily armed than most previous ships classified as guided missile cruisers.

Guided missile destroyer

A guided-missile destroyer is a destroyer designed to launch guided missiles. Many are also equipped to carry out anti-submarine, anti-air, and anti-surface operations. The NATO standard designation for these vessels is DDG. Nations vary in their use of destroyer D designation in their hull pennant numbering, either prefixing or dropping it altogether. The U.S. Navy has adopted the classification DDG in the American hull classification system.

In addition to the guns, a guided-missile destroyer is usually equipped with two large missile magazines, usually in vertical-launch cells. Some guided-missile destroyers contain powerful radar systems, such as the United States’ Aegis Combat System, and may be adopted for use in an anti-missile or ballistic-missile defense role. This is especially true of navies that no longer operate cruisers, so other vessels must be adopted to fill in the gap.

Hobart-class destroyer

The Hobart class is a ship class of three air warfare destroyers (AWDs) being built for the Royal Australian Navy (RAN). Planning for ships to replace the Adelaide-class frigates and restore the capability last exhibited by the Perth-class destroyers began by 2000, initially under acquisition project SEA 1400, which was re-designated SEA 4000. Although the designation "Air Warfare Destroyer" is used to describe ships dedicated to the defence of a naval force (plus assets ashore) from aircraft and missile attack, the planned Australian destroyers are expected to also operate in anti-surface, anti-submarine, and naval gunfire support roles.

Planning for the Australian Air Warfare Destroyer (as the class was known until 2006) continued through the mid-2000s, with the selection of the Aegis combat system as the intended combat system and ASC as the primary shipbuilder in 2005. In late 2005, the AWD Alliance was formed as a consortium of the Defence Materiel Organisation (DMO), ASC, and Raytheon. Between 2005 and 2007, Gibbs & Cox's Evolved Arleigh Burke-class destroyer concept and Navantia's Álvaro de Bazán-class frigate competed for selection as the AWD design. Although the Arleigh Burke design was larger and more capable, the Álvaro de Bazán design was selected in June 2007 as it was an existing design, and would be cheaper, quicker, and less risky to build.

Three ships were ordered in October 2007, and will be assembled at ASC's facility in Osborne, South Australia, from 31 pre-fabricated modules (or 'blocks'). An option to build a fourth destroyer was included in the original contract, but has not been exercised. ASC, NQEA Australia, and the Forgacs Group were selected in May 2009 to build the blocks, but within two months, NQEA was replaced by BAE Systems Australia. Construction errors and growing delays led the AWD Alliance to redistribute the construction workload in 2011, with some modules to be built by Navantia. Increasing slippage has pushed the original planned 2014-2016 commissioning dates out by at least three years, with lead ship Hobart to be completed by June 2017, Brisbane in September 2018, and Sydney by March 2020. The AWD Alliance, Navantia, and the involved shipyards have been criticised for underestimating risks, costs, and timeframes; faulty drawings and bad building practices leading to repeated manufacturing errors; and blame-passing. The alliance concept has been panned for having no clear management structure or entity in charge, and having the DMO simultaneously acting as supplier, build partner, and customer for the ships.

JS Haguro

JS Haguro (DDG-180) is a Maya-class guided missile destroyer in the Japan Maritime Self-Defense Force (JMSDF). Haguro was named for Mount Haguro.

JS Maya

JS Maya (DDG-179) is a Maya-class guided missile destroyer in the Japan Maritime Self-Defense Force (JMSDF). Maya was named for Mount Maya and shares her name with a World War II heavy cruiser.

Japanese ship Haguro

At least two warships of Japan have borne the name Haguro:

Japanese cruiser Haguro, was a Myōkō-class cruiser launched in 1928 and sunk in 1945

JS Haguro, is a Maya-class destroyer launched in 2019

Japanese ship Maya

At least three warships of Japan have borne the name Maya:

Japanese gunboat Maya, was a Maya-class gunboat launched in 1886 and struck in 1911

Japanese cruiser Maya, was a Takao-class cruiser launched in 1930 and sunk in 1944

Japanese destroyer Maya, is a Maya-class destroyer launched in 2018

Type 07 Vertical Launch Anti-submarine rocket

Type 07 Vertical Launch Anti-submarine rocket (07式垂直発射魚雷投射ロケット, 07-shiki-suichoku-hassha-gyorai-tōsha-roketto) is a Japanese ship-launched anti-submarine missile.

Type 12 Surface-to-Ship Missile

The Type 12 Surface-to-Ship Missile (12式地対艦誘導弾) is a truck-mounted anti-ship missile developed by Japan's Mitsubishi Heavy Industries in 2012. It is an upgrade of the Type 88 Surface-to-Ship Missile. The Type 12 features INS with mid-course GPS guidance and better precision due to enhanced Terrain Contour Matching and target discrimination capabilities. The weapon is networked, where initial and mid-course targeting can be provided by other platforms, and also boasts shorter reload times, reduced lifecycle costs, and a range of 124 mi (108 nmi; 200 km).The missile shares the same Ka-band Active Electronic Scanned Array(AESA) radar seeker with Japanese BVRAAM missile, AAM-4B.The ship-launched derivative of Type 12, designated as Type 17 (SSM-2) missile has been put into service and it is to start deploying from Maya-class destroyer. The range has doubled to 400 kilometers and is also planning to re-apply for the improved version of the surface-to-ship system and the air-launched variant for the P-1 patrol aircraft.

Vertical launching system

A vertical launching system (VLS) is an advanced system for holding and firing missiles on mobile naval platforms, such as surface ships and submarines. Each vertical launch system consists of a number of cells, which can hold one or more missiles ready for firing. Typically, each cell can hold a number of different types of missiles, allowing the ship flexibility to load the best set for any given mission. Further, when new missiles are developed, they are typically fitted to the existing vertical launch systems of that nation, allowing existing ships to use new types of missiles without expensive rework. When the command is given, the missile flies straight up long enough to clear the cell and the ship, and then turns on course.

A VLS allows surface combatants to have a greater number of weapons ready for firing at any given time compared to older launching systems such as the Mark 13 single-arm and Mark 26 twin-arm launchers, which were fed from behind by a magazine below the main deck. In addition to greater firepower, VLS is much more damage tolerant and reliable than the previous systems, and has a lower radar cross-section (RCS). The U.S. Navy now relies exclusively on VLS for its guided missile destroyers and cruisers.

The most widespread vertical launch system in the world is the Mark 41, developed by the United States Navy. More than 11,000 Mark 41 VLS missile cells have been delivered, or are on order, for use on 186 ships across 19 ship classes, in 11 navies around the world. This system currently serves with the US Navy as well as the Australian, Danish, Dutch, German, Japanese, New Zealand, Norwegian, South Korean, Spanish, and Turkish navies, while others like the Greek Navy preferred the similar Mark 48 system.The advanced Mark 57 vertical launch system is used on the new Zumwalt-class destroyer. The older Mark 13 and Mark 26 systems remain in service on ships that were sold to other countries such as Taiwan and Poland.

When installed on an SSN (nuclear-powered attack submarine), a VLS allows a greater number and variety of weapons to be deployed, compared with using only torpedo tubes.
