NGI
The Next Generation Interceptor (NGI) is a new missile being developed to protect the U.S. homeland by intercepting and destroying incoming long-range ballistic missiles in space. It is designed to replace the aging interceptors of the current Ground-based Midcourse Defense system.

TECHNICAL DEFINITION
The Next Generation Interceptor (NGI) is an advanced kinetic kill vehicle developed for the U.S. Missile Defense Agency's (MDA) Ground-based Midcourse Defense (GMD) system. Designed by contractors like Lockheed Martin and Northrop Grumman, the NGI provides a multi-kill vehicle (MKV) capability to neutralize complex intercontinental ballistic missile (ICBM) threats during their midcourse phase of flight.
BACKGROUND
The Ground-Based Interceptor (GBI) is the anti-ballistic missile component of the United States' Ground-Based Midcourse Defense (GMD) system. It is designed to intercept intercontinental ballistic missiles.

DEVELOPERS
Organizations developing technology related to NGI.
The prime contractor selected by the U.S. Missile Defense Agency in April 2024 to design, develop, and deliver the Next Generation Interceptor (NGI) to protect the U.S. homeland against intercontinental ballistic missile threats.
Was one of two prime contractors competing to develop the NGI. The company developed a complete interceptor design through the technology development and risk reduction phase of the program before the MDA down-selected to a single vendor.
A major subcontractor to Lockheed Martin, developing the kill vehicle for the NGI. The kill vehicle is the component that separates from the booster rocket to seek out and destroy the incoming threat warhead using kinetic force.
A key supplier providing the solid rocket motor propulsion systems for the Lockheed Martin NGI design. These motors provide the thrust to boost the interceptor into space to engage its target.
The U.S. Department of Defense agency responsible for managing the development, procurement, and fielding of the NGI program as part of the nation's layered ballistic missile defense system.
As the prime contractor for the overall Ground-Based Midcourse Defense (GMD) system, Boeing is responsible for integrating the new NGI interceptors into the existing GMD command and control, battle management, and communications (C2BMC) architecture.
