Kongō-class destroyer

The Kongō class (こんごう型護衛艦 Kongō-gata Goeikan) of guided missile destroyers serves as the core ship of the Japan Maritime Self-Defense Force (JMSDF)'s Escort Flotillas. Constructed in the 1990s, the Kongō class are equipped with the Aegis fire control system, being one of the few ship classes outside the United States to have that capability.

Design

The Kongō class employs the highly advanced Aegis fire control system and is armed with the RIM-66 SM-2MR Block II surface-to-air missile, RUM-139 vertically launched anti-submarine rocket, the RGM-84 Harpoon anti-ship missile, two Mark 15 20 mm CIWS gun mounts, two torpedo mounts in a triple tube configuration, and an Oto Melara 127 mm (5 in)/54 caliber gun. Their Mark 41 vertical launch system can hold 90 missiles. However, in keeping with the defensive mission of the JMSDF and passive role of the Japan Self-Defense Forces in general, the Kongō class lacks the Tomahawk missile.

As on other ships employing the Aegis system, the superstructure is dominated by the SPY-1's phased arrays, which eliminates the need for a traditional rotating antenna. The design of the superstructure also incorporates certain stealth features, designed to reduce radar cross section of the ship; however, as a consequence, the ship is considerably more top-heavy than a typical destroyer and requires a much deeper draft. As such, operations in a littoral (coastal) environment are limited. Overall, Kongō-class destroyers are much larger than traditional destroyers and at 9,485 tons displacement come close to cruisers in size. Because they are built to different operational requirements than the Arleigh Burke-class ships, such as for carrying extra equipment for commanding a squadron, the Kongō-class ships' internal arrangement is quite different from the original design on which they are based. Recognisable external features are the vertical mast and the sleek sides of the bridge.

The Kongō-class vessels are being modified to serve in a theater missile defense role, with the primary intention of countering North Korean ballistic missiles. This purpose and a financial crisis made the Flight II variant of the Arleigh Burke class the choice for the follow-on class to the Tachikaze and Asakaze. The new destroyer class was named Atago in 2005.

Kongō-class destroyers are powered by four Ishikawajima-Harima LM2500 gas turbines giving them a top speed of 30 knots (56 km/h; 35 mph).

In December 2007, Japan conducted a successful test of the SM-3 block IA against a ballistic missile aboard Kongō. This was the first time a Japanese ship was selected to launch the interceptor missile during a test of the Aegis Ballistic Missile Defense System. In previous tests they provided tracking and communications.[1][2] Afterward, Japan has also undertaken another two successful Ballistic Missile Defense test aboard Myōkō in October 2009[3] and aboard Kirishima in October 2010.[4] While one test aboard Chōkai in November 2008 failed to intercept the target.[5]

Namesakes

The Kongō-class destroyers are named after mountains in Japan, and all four also share their names with World War II era Japanese warships. Kongō and Kirishima share their names with two ships of the Kongō-class battlecruiser, while the other two ships share their names with the heavy cruisers Myōkō and Chōkai.

In popular culture

  • In the anime series Neon Genesis Evangelion, it appears in the eighth episode, when Evangelion Unit-02 is delivered from Germany to Japan (also seen is the Arleigh Burke class USS Ramage). In High School of the Dead, the Kongō's CIC intercepts three of nuclear warheads while the Arleigh Burke class USS Curtis Wilbur fails to shoot down the fourth.
  • The JMSDF allowed the producers of the Japanese movie 亡国のイージス ("Boukoku no Aegis") to shoot aboard Myōkō, which stood in as the film's Aegis destroyer, called the いそかぜ (Isokaze). The DDG-175 hull number was retained for the movie. The ship would later appear in the 2012 movie Battleship
  • In the Tom Clancy novel Debt of Honor, the fictional lead ship of the line, Mutsu, figured prominently in a Japanese plot to wrest the U.S. Navy's control of the Western Pacific region.
  • The Ace Combat series of flight simulation video games used the Kongō class in several missions where the player faces naval forces. The game Wargame: Red Dragon depicts the Kongō-class destroyer as one of the ships available to NATO forces.

Battleship (film)

Battleship is a 2012 American military science fiction action film that is loosely based on the board game of the same name. The film was directed by Peter Berg and stars Taylor Kitsch, Brooklyn Decker, Rihanna, Tadanobu Asano, Alexander Skarsgård and Liam Neeson. Filming took place in Hawaii and on USS Missouri. In the film, the crews of a small group of warships are forced to do battle against a naval fleet of extraterrestrial origin in order to thwart their destructive goals.

Battleship premiered in Tokyo on April 3, 2012 and received a wide release by Universal Pictures on May 18, 2012. It received mixed to negative reviews and underperformed at the box office, making only $65 million in North America against its total gross of $303 million worldwide.

General Electric LM2500

The General Electric LM2500 is an industrial and marine gas turbine produced by GE Aviation. The LM2500 is a derivative of the General Electric CF6 aircraft engine.

The LM2500 is available in 3 different versions:

The LM2500 delivers 33,600 shaft horsepower (shp) (25,060 kW) with a thermal efficiency of 37 percent at ISO conditions. When coupled with an electric generator, it delivers 24 MW of electricity at 60 Hz with a thermal efficiency of 36 percent at ISO conditions.

The improved, 3rd generation, LM2500+ version of the turbine delivers 40,500 shp (30,200 kW) with a thermal efficiency of 39 percent at ISO conditions. When coupled with an electric generator, it delivers 29 MW of electricity at 60 Hz with a thermal efficiency of 38 percent at ISO conditions.

The latest, 4th generation, LM2500+G4 version was introduced in November 2005 and delivers 47,370 shp (35,320 kW) with a thermal efficiency of 39.3 percent at ISO conditions.As of 2004, the U.S. Navy and at least 29 other navies had used a total of more than one thousand LM2500/LM2500+ gas turbines to power warships. Other uses include hydrofoils, hovercraft and fast ferries.

In 2012, GE developed an FPSO version to serve the oil and gas industry's demand for a lighter, more compact version to generate electricity and drive compressors to send natural gas through pipelines.

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.

Otobreda 127/54 Compact

The Otobreda 127mm/54 Compact (127/54C) gun is a dual purpose naval artillery piece built by the Italian company Oto Melara. It uses the 127mm round which is also used in the 5 inch/ 54 gun, albeit that this gun calibre is measured in United States customary units rather than metric. The gun uses an automatic loading system where 66 127mm rounds of various kinds can be stored ready-to-fire in three loader drums (each holding 22 rounds). The barrel is water-cooled. Currently the gun is still in use by navies around the world but it is slowly being replaced by the Otobreda 127/64 for new vessels, such as the German Navy's F125-class frigate and Italian Navy's FREMM.

Submarine Super 99

Submarine Super 99 (Japanese: 潜水艦スーパー99, Hepburn: Sensuikan Sūpā Nain Nain) is a manga series written and illustrated by Leiji Matsumoto. It was adapted into an anime that aired on AT-X.

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.
