This interceptor is made up of a boost vehicle, constructed by Orbital Sciences Corporation, and an Exoatmospheric Kill Vehicle (EKV), built by Raytheon. Integration of these is performed by Boeing Defense, Space & Security.
The three-stage Orbital Boost Vehicle (OBV) uses the solid-fuel rocket upper stages of the Taurus launcher. The interceptor version deployed in the U.S. has three stages. A two-stage version was successfully tested in 2010 for use in Europe's NATO missile defence as a backup option to the preferred Aegis System Standard Missile 3.
A total of 64 interceptors are planned: 30 interceptors were deployed at the end of 2010 at Fort Greely, Alaska and Vandenberg Air Force Base in California. with fourteen additional missiles deployed by 2017, and 20 more GBIs planned. Since 2006, the Missile Defense Agency conducted seven intercept tests with the operationally configured missile, four of which were successful.
The FY2021 NDAA (National Defense Authorization Act for Fiscal Year 2021, which was released 3 December 2020) has mandated that the Missile Defense Agency commence development of 20 interim GBIs. The interim GBIs are to meet the requirements for the Redesigned Kill Vehicle (RKV —canceled 21 Aug 2019), at minimum::see attached video
- Vehicle-to-vehicle communications
- Ability to assess kills, and counter counter-measures
- Use mature technology, with the ability to integrate with non-GBIs (see below)
The interim GBIs are to be completely fielded by 2026, accoring to the FY2021 NDAA.
Next generation interceptor (NGI)
The Missile Defense Agency (MDA) is one source for anti-ballistic missiles for defense of the American homeland. The Next generation interceptor (NGI) is an MDA program to upgrade the kill vehicles for the ground-based interceptors described above, but different system integrators compete to replace Boeing. The competing system integrators are Lockheed Martin and Northrup Grumman. They are tasked with meeting more complex threats than those met by the EKV. There will be more near-term technology improvement to the GBI during a longer-term process for NGI to meet more complex threats. The NGIs are to be fielded by 2027 or 2028.
The Pentagon's Office of Cost and Program Evaluation (CAPE) estimated on April 29, 2021, that it would cost $17.7 billion to develop, deploy, and maintain the next-generation interceptor (NGI). This includes billions to build a total of 21 NGIs, each with a price tag of at least $74 million, and maybe more, depending on the exact allocation of funding for the program. As part of the first phase, the Missile Defense Agency allocated $7.6 billion in contract money to Northrop Grumman (in partnership with Raytheon) and Lockheed Martin to upgrade aging ground-based interceptors.
