The Missile Defense Agency leads the development of anti-ballistic missiles for North America. The Next Generation Interceptor (NGI) [21]: 4:13 is a MDA program to upgrade the kill vehicles for the ground-based interceptors, with different vendors, Lockheed Martin and Northrop Grumman competing.

Missile defense is a system, weapon, or technology involved in the detection, tracking, interception, and also the destruction of attacking missiles.Conceived as a defense against nuclear-armed intercontinental ballistic missiles (ICBMs), its application has broadened to include shorter-ranged non-nuclear tactical and theater missiles.
A Ground-Based Interceptor loaded into a silo at Fort Greely, Alaska in July 2004.. Ground-Based Midcourse Defense (GMD), previously National Missile Defense (NMD), is an anti-ballistic missile system implemented by the United States of America for defense against ballistic missiles, during the midcourse phase of ballistic trajectory flight.
The principal intended phase of ballistic missile interception is noted. Other phases may be tried, with less effect. The earlier in flight that a missile is intercepted, the greater area a system may defend. Mid-course interception requires an ABM launch position between the ballistic missile launch site and the area defended.
The EKV is boosted to an intercept trajectory by a boost vehicle (missile), where it separates from the boost vehicle and autonomously collides with an incoming warhead. The EKV is launched by the Ground-Based Interceptor (GBI) missile, the launch vehicle of the GMD system. The EKV's own rockets and fuel are for corrections in the trajectory ...
The interceptor missile was a SC-19. [21] [22] The sources suggest the system was not operationally deployed as of 2010. [21] [23] On 27 January 2013, China conducted another anti-ballistic missile test. According to the Chinese Defense Ministry, the missile launch was defensive in character and was not aimed against any countries.
The logo of the Missile Defense division of the U.S. National Guard, part of the modern American missile defense system In the 1990s and early 21st century, the stated mission of NMD has changed to the more modest goal of preventing the United States from being subject to nuclear blackmail or nuclear terrorism by a so-called rogue state .
This led to the HiBEX and UpSTAGE missile experiments that tested accelerations as high as 377 g. There was some interest by the Army and US Air Force in the concept, which continued studying the basic concept under the name Hardsite. Ultimately, as had been the case several times in the past, the Air Force eventually rejected any Army ...
