2065438+On April 26th, 2007, two launch vehicles and X-band radar of Saad anti-missile system were put into use in Korea. The U.S. Department of Defense said that it will continuously upgrade South Korea's Thaad system in the future.
2065438+On July 29th, 2007, South Korean President Moon Jae in issued an order to immediately negotiate with the United States on a plan to strengthen the strategic containment of South Korea and the United States, including the additional deployment of the remaining four "Sade" launch vehicles.
Terminal High Altitude Area Defense (THAAD) is a land-based theater anti-missile system under the command of the US Missile Defense Agency and the US Army, generally referred to as THAAD anti-missile system.
The contractors of "Sade" system are Lockheed Martin, Boeing and Raytheon. A "Sade" system usually consists of a command vehicle, a fire control radar, six 8-pack launchers and 48 interceptors. Its technical and tactical performance has many unique characteristics.

Development background
Terminal high altitude area defense is the predecessor of theater high altitude area defense system, which ended in many failures. In 2004, the US Army redesigned the system and changed its name to its current name, similar to the Navy's Aegis combat system. It consists of command system, interception system, launching system, radar and its supporting equipment. June 5438+October 2007 10, the terminal high altitude area defense successfully completed the interception test outside the atmosphere at the US Pacific missile range.
Terminal high altitude area defense, as a special defense system for dealing with large-scale ballistic missile attacks, has the unique advantage of providing more flexible use options for combat troops while defending against large-scale missile threats.
Its purpose is not to replace but to supplement the MIM- 104 air defense missile, the Navy Aegis ballistic missile defense system, the land-based midcourse defense system and the early warning radar and sensors deployed by the United States around the world, thus enabling the US military to have multi-layer ballistic missile defense capabilities. On July 8, 20 16, the United States and South Korea officially announced that they would deploy the Sadr anti-missile system in South Korea, which caused great controversy in South Korea and strong dissatisfaction among regional countries.
After the Gulf War, the MIM- 104 air defense missile used by the United States in the war belongs to low-altitude air defense missile, with the maximum launching height of only about 20 kilometers, which is mainly used to protect small and important targets. The defense area is small, and the interception is not carried out in a high enough space. Moreover, missile fragments caused by interception often fall on the territory of their own countries or friendly countries, which will also cause damage to people and assets on the ground.
If the enemy uses weapons of mass destruction, such as nuclear warheads and chemical warheads, low-altitude interception like this has little effect. Therefore, it is necessary to develop a high-tech technology that can intercept incoming ballistic missiles at a longer distance and at a higher altitude. 1987, the us army space and strategic defense command put forward the development plan of high-altitude defense technology for theater ballistic missile defense.
