The in the Japan Maritime Self-Defense Force is a modified version of the , with an updated Aegis Combat System and electric propulsion system. ''Maya'' was commissioned on March 19, 2020. ''Haguro'' was commissioned on March 19, 2021. Background The Maritime Self-Defense Force (MSDF) began construction of the Aegis-equipped in FY1988. In FY2002 and 2003, a modified version, , was also added for its fleet. However, even after the four ''Kongō''-class and two ''Atago''-class destroyers had been commissioned, it was still necessary to build two more Aegis-equipped destroyers to replace , the best and last survivor of Tartar-equipped destroyers. The construction of these two Aegis-equipped destroyers was included in the National Defense Program Guidelines for FY2014 and beyond. The first ship, JS ''Maya'', was built in the FY2015 budget. Design While it shares the same design characteristics as the ''Atago'' class, the ''Maya'' class possesses a larger hull to install a ...

RIM-161 Standard
The RIM-161 Standard Missile 3 (SM-3) is a ship-based surface-to-air missile system used by the United States Navy to intercept short- and intermediate-range ballistic missiles as a part of Aegis Ballistic Missile Defense System. Although primarily designed as an anti-ballistic missile, the SM-3 has also been employed in an anti-satellite capacity against a satellite at the lower end of low Earth orbit.Pentagon news briefing of February 14, 2008video : although no name for the satellite is given, the launch date of December 14, 2006 is stated The SM-3 is primarily used and tested by the and also operated by the |
RIM-66 Standard
The RIM-66 Standard MR (SM-1MR/SM-2MR) is a medium-range surface-to-air missile (SAM), with a secondary role as an anti-ship missile, originally developed for the United States Navy (USN). A member of the Standard Missile family of weapons, the SM-1 was developed as a replacement for the RIM-2 Terrier and RIM-24 Tartar that were deployed in the 1950s on a variety of USN ships. The RIM-67 Standard (SM-1ER/SM-2ER) is an extended range version of this missile with a solid rocket booster stage. Description The Standard missile program was started in 1963 to produce a family of missiles to replace existing guided missiles used by the Terrier, Talos, and Tartar guided missile systems. The intention was to produce a new generation of guided missiles that could be retrofit to existing guided missile systems. Standard Missile 1 The RIM-66A is the medium ranged version of the Standard missile and was initially developed as a replacement for the earlier RIM-24C as part of the Mk74 "Tar ...

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 far enough to clear the cell and the ship, then turns on to the desired 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 ...

Mark 41 Vertical Launching System
The Mark 41 Vertical Launching System (Mk 41 VLS) is a shipborne missile canister launching system which provides a rapid-fire launch capability against hostile threats. The Vertical Launch System (VLS) concept was derived from work on the Aegis Combat System. History Refinement of the initial concept of Aegis system in the 1960s continued through the 1960s and 1970s, and the Mk 41 was conceived in 1976. Originally, the system was only intended to fire the RIM-66 Standard missile, but the height of the Mk 41 was increased to accommodate the larger Tomahawk missile. The prototype for the launcher was tested and evaluated on board . The first operational launcher was installed aboard . Specifications Mark 41 (Mk 41) The Mk 41 is capable of firing the following missiles: * RIM-66 Standard * RIM-67 Standard * RIM-161 Standard Missile 3 * RIM-174 Standard ERAM * RGM-109 Tomahawk * RUM-139 VL-ASROC anti-submarine missile * RIM-7 Sea Sparrow anti-air missile * RIM-162 ESSM * Join ...

Type 97 Light Weight Torpedo (G-RX4)
The Type 97 Torpedo (97式短魚雷, 97 Shiki Tan Gyorai) is a short-range torpedo developed and built by the Mitsubishi Heavy Industries for the Japanese Maritime Self Defense Force. This type of torpedo, like many other modern Japanese weapons systems, is not exported. Development At the end of the Cold War, Soviet attack submarines were capable of moving at higher speed and diving at lower depth, rendering the torpedoes used by US navy and the JMSDF, like the Mk-46 torpedo, less able to deal with them. So a new type of torpedo needed to be developed. The US launched a new type of torpedo, the Mk-50 using an infrared detector and a closed-loop pump with an integrated processing unit for analyzing underwater sound waves for target acquisition. This type of torpedo can also be used to intercept other torpedoes. Soviet submarines, however, have developed adaptive capabilities, such as the use of trap baits and interference of the detection system, making it harder for the t ...

Mark 46 Torpedo
The Mark 46 torpedo is the backbone of the United States Navy's lightweight anti-submarine warfare torpedo inventory and is the NATO standard. These aerial torpedoes are designed to attack high-performance submarines. In 1989, an improvement program for the Mod 5 to the Mod 5A and Mod 5A(S) increased its shallow-water performance. The Mark 46 was initially developed as Research Torpedo Concept I (RETORC I), one of several weapons recommended for implementation by Project Nobska, a 1956 summer study on submarine warfare.

Torpedo Tube
A torpedo tube is a cylindrical device for launching torpedoes. There are two main types of torpedo tube: underwater tubes fitted to submarines and some surface ships, and deck-mounted units (also referred to as torpedo launchers) installed aboard surface vessels. Deck-mounted torpedo launchers are usually designed for a specific type of torpedo, while submarine torpedo tubes are general-purpose launchers, and are often also capable of deploying mines and cruise missiles. Most modern launchers are standardized on a diameter for light torpedoes (deck mounted aboard ship) or a diameter for heavy torpedoes (underwater tubes), although other sizes of torpedo tube have been used: see Torpedo classes and diameters. Submarine torpedo tube A submarine torpedo tube is a more complex mechanism than a torpedo tube on a surface ship, because the tube has to accomplish the function of moving the torpedo from the normal atmospheric pressure within the submarine into the sea at the ambient ...
