According to news published by the Chinese press agency Xinhuanet on December 18, 2020, Japan government has approved the construction of two AEGIS vessels. The Aegis Combat System is an American integrated naval weapons system developed by the Missile and Surface Radar Division of RCA (Radio Corporation of America), and now produced by Lockheed Martin.
AEGIS was initially developed by the Missile and Surface Radar Division of RCA (Radio Corporation of America), which was later acquired by General Electric. The division responsible for the Aegis systems became Government Electronic Systems. This, and other GE Aerospace businesses, were sold to Martin Marietta in 1992. This became part of Lockheed Martin in 1995.
The Lockheed Martin-developed Aegis Weapon System is the world’s premier naval air defense system and the sea-based element of the United States’ Ballistic Missile Defense System. The Aegis Weapon System is a seamlessly integrated radar and missile system capable of simultaneous operation defending against advanced air, surface, and subsurface threats.
The Aegis Weapon System is the most deployed combat system in the world, and its flexible system architecture enables it to fulfill a variety of missions. Its unique open architecture allows the system to maintain interoperability across global domains on 118 ships, 10 ship classes, and seven countries to protect warfighters. The AEGIS is operated by combat ships of the United States, Norway, Spain, South Korea, Japan and Australia.
In the U.S. navy, the Aegis Combat System (ACS) is an advanced command and control (command and decision, or C&D, in Aegis parlance) and weapon control system (WCS) that uses powerful computers and radars to track and guide weapons to destroy enemy targets.
The ACS is composed of the Aegis Weapon System (AWS), the fast-reaction component of the Aegis Anti-Aircraft Warfare (AAW) capability, along with the Phalanx Close-In Weapon System (CIWS), and the Mark 41 Vertical Launch System.
The Mark 41 Vertical Launching System (Mk 41 VLS) is a shipborne missile canister launching system that provides a rapid-fire launch capability against hostile threats. The Phalanx is a close-in weapon system (CIWS) providing air defense against incoming threats such as small boats, surface torpedoes, anti-ship missiles, and helicopters.
The AEGIS also includes AN/SPY-1 Radar, MK 99 Fire Control System, WCS, the Command and Decision Suite, and SM-2 Standard Missile family of weapons; these include the basic RIM-66 Standard, the RIM-67 extended-range missile, and the newer RIM-161 designed to counter ballistic missile threats.
Recently, the American Company has developed the SPY-6(V)1 Air and Missile Defense Radar (AMDR), the next-generation radar for the Aegis Combat System deployed on Arleigh Burke-class guided-missile destroyers (DDGs).
In the U.S. Navy, the AEGIS combat system is mounted on Constellation-class destroyer, Arleigh Burke-class destroyer, and Ticonderoga-class cruiser.
