In naval terminology, a destroyer is a fast, manoeuvrable, long-endurance warship intended to escort larger vessels in a fleet, convoy or battle group and defend them against powerful short range attackers. They were originally developed in 1885 by Fernando Villaamil for the Spanish Navy as a defense against torpedo boats, and by the time of the Russo-Japanese War in 1904, these "torpedo boat destroyers" (TBDs) were "large, swift, and powerfully armed torpedo boats designed to destroy other torpedo boats". Although the term "destroyer" had been used interchangeably with "TBD" and "torpedo boat destroyer" by navies since 1892, the term "torpedo boat destroyer" had been generally shortened to simply "destroyer" by nearly all navies by the First World War.
The Aegis Combat System is an American integrated naval weapons system developed by the Missile and Surface Radar Division of RCA, and it is now produced by Lockheed Martin.
The Zumwalt-class destroyer is a class of three United States Navy guided-missile destroyers designed as multi-mission stealth ships with a focus on land attack. It is a multi-role class that was designed with a primary role of naval gunfire support and secondary roles of surface warfare and anti-aircraft warfare. The class design emerged from the DD-21 "land attack destroyer" program as "DD(X)" and was intended to take the role of battleships in meeting a congressional mandate for naval fire support. The ship is designed around its two Advanced Gun Systems (AGS), turrets with 920 round magazines, and unique Long Range Land Attack Projectile (LRLAP) ammunition. LRLAP procurement was canceled, rendering the guns unusable, so the Navy re-purposed the ships for surface warfare. Starting in 2023, the Navy will remove the AGS from the ships and replace them with hypersonic missiles.
The Japan Maritime Self-Defense Force, abbreviated JMSDF, also simply known as the Japanese Navy, is the maritime warfare branch of the Japan Self-Defense Forces, tasked with the naval defense of Japan. The JMSDF was formed following the dissolution of the Imperial Japanese Navy (IJN) after World War II. The JMSDF has a fleet of 154 ships, 346 aircraft and 50,800 personnel.
The CG(X) program, also known as the Next Generation Cruiser program, was a United States Navy research program to develop a replacement vessel for its 22 Ticonderoga-class cruisers. Original plans were for 18–19 ships, based on the 14,500 ton Zumwalt-class destroyer with additional ballistic missile defense and area air defense for a carrier group. These vessels were to enter service beginning in 2017. The program was ended in 2010 with its mission to be fulfilled by the successor to the Flight III Arleigh Burke–class destroyers.
The Murasame-class destroyer is a class of destroyers, serving with the Japan Maritime Self-Defense Force (JMSDF). This is the first class of the second-generation general-purpose destroyers of the JMSDF.
The Asagiri-class destroyer is a class of destroyer, serving with the Japan Maritime Self-Defense Force (JMSDF). It was the second class of first-generation general-purpose destroyers of the JMSDF.
The Akizuki class of destroyers of the Japan Maritime Self-Defense Force is intended to escort the Hyūga-class and Izumo-class helicopter destroyers, and safeguard the other Aegis-capable warships such as the Kongō class and Atago class. The destroyer provides defense against surface, airborne and undersea threats. The class was initially designated as "19DD", referring to a date on the Japanese calendar, specifically the 19th fiscal year of the Heisei period (2007).
SC-21 was a research and development program started in 1994 intended to design land attack ships for the United States Navy. A wide variety of designs were created and extensively examined, including an arsenal ship with 500 cruise missiles. Eventually a "tumblehome" design of around 16,000 tons with two long-range guns and 128 missile tubes was selected as the DD-21, the Destroyer for the 21st century. The program ended in November 2001.
The Asahi class of destroyers of the Japan Maritime Self-Defense Force is optimized for undersea warfare. The class was initially designated "25DD", referring to a date on the Japanese calendar, specifically the 25th fiscal year of the Heisei period (2013).
The Maya class of guided-missile destroyers in the Japan Maritime Self-Defense Force is a modified version of the Atago class, with an updated Aegis Combat System and electric propulsion system. Maya was commissioned on March 19, 2020. Haguro was commissioned on March 19, 2021.
The Mogami-class frigate is a Japanese multi-mission stealth frigate for the Japan Maritime Self-Defense Force (JMSDF).
The Acquisition, Technology & Logistics Agency is an agency established under the Ministry of Defense that handles project management, technology management, research and development, and procurement of defense equipment for the Japan Self-Defense Forces. ATLA's formation is also seen as part of Prime Minister Shinzō Abe defense policy to bolster the military by streamlining and reforming Japan's defense industry and equipment acquisition.
The Taigei-class submarines (29SS) (Japanese: たいげい, "Big Whale") is a new class of attack submarines developed for the Japan Maritime Self-Defense Force. It is the successor to the Sōryū class. The Taigei class is equipped with a large amount of lithium-ion batteries, as is the case with the eleventh and twelfth submarines of the Sōryū class, making it possible for the submersible to travel longer and at higher speeds under water than conventional diesel-electric submarines.
JS Asahi (DD-119) is the lead ship of the Asahi-class destroyer of the Japanese Maritime Self-Defense Force. Her namesake came from “Morning sun”.
JS Shiranui (DD-120) is the second ship of the Asahi-class destroyer of the Japanese Maritime Self-Defense Force. Her namesake came from the optical phenomenon called Shiranui, or "Phosphorescent Light".
JS Asuka (ASE-6102) is an experimental ship of the Japan Maritime Self-Defense Force. The vessel was constructed by Sumitomo Heavy Industries of Tokyo, Japan and was launched on 21 June 1994. Asuka was commissioned on 22 March 1995 and since then has conducted performance confirmation tests for integrated navigation systems.
The DDG(X) program, also known as the Next-Generation Guided-Missile Destroyer program, is a United States Navy program to develop a class of surface combatant vessels to succeed its 22 Flight II Ticonderoga-class cruisers and 27 Flight I/II Arleigh Burke-class destroyers. The program is the culmination of the Large Surface Combatant (LSC) initiative that followed the cancellation of CG(X) and curtailing of the procurement of the Zumwalt-class destroyer. The ships will become the principal large surface combatants of the U.S. Navy; compared to their predecessors, they will incorporate more powerful sensors and have more room and weight margin for growth.
Aegis system equipped vessels (ASEV) or イージス・システム搭載艦 in Japanese is the designation for a proposed pair of cruiser-sized ballistic missile defense (BMD) warships to be operated by the Japanese Maritime Self Defense Force (JMSDF) as dedicated ship-based BMD platforms, serving as an alternative to Japan's now-cancelled land-based Aegis Ashore BMD system. When completed, the two warships will be the largest surface combatant ships in service with the JMSDF, and according to Popular Mechanics, they will "arguably [be] the largest deployable surface warships in the world."
