    @AMDR what's the current GBI missile look like? I know it's been redesigned a few(?) times due to failed tests and deficiencies in the missile's performance. The bus looks standard, at least in comparison to that on SM-3:

    But what's the current GBI missile design? This is the old version right?

    And this the current(?) version?

    Ground-based Midcourse Defense System Conducts Successful Flight Test

    16-NEWS-0002
    January 28, 2016

    The U.S. Missile Defense Agency, in cooperation with the U.S. Air Force 30th Space Wing, the Joint Functional Component Command for Integrated Missile Defense, and U.S. Northern Command, today conducted a non-intercept flight test of the Ground-based Midcourse Defense (GMD) element of the nation’s Ballistic Missile Defense System (BMDS). A long-range ground-based interceptor was launched from Vandenberg Air Force Base, Calif., successfully evaluating performance of alternate divert thrusters for the system’s Exoatmospheric Kill Vehicle.

    During the test, a target representing an intermediate-range ballistic missile was air-launched from a U.S. Air Force C-17 aircraft over the broad ocean area west of Hawaii. An Army Navy/Transportable Radar Surveillance and Control Model 2 (AN/TPY-2) radar in Forward Based Mode, located at the Pacific Missile Range Facility, Kauai, Hawaii, detected the target and relayed target track information to the Command, Control, Battle Management, and Communication system. The Sea-Based X-band radar, positioned in the broad ocean area northeast of Hawaii, also acquired and tracked the target. The GMD system received track data and developed a fire control solution to engage the target. The test also included a demonstration of technology to discriminate countermeasures carried by the target missile.

    A three-stage Ground-Based Interceptor was launched from Vandenberg AFB, performed fly-out, and released a Capability Enhancement-II Exoatmospheric Kill Vehicle. The kill vehicle performed scripted maneuvers to demonstrate performance of alternate divert thrusters. Upon entering terminal phase, the kill vehicle initiated a planned burn sequence to evaluate the alternate divert thrusters until fuel was exhausted, intentionally precluding an intercept.

    Program officials will evaluate system performance based upon telemetry and other data obtained during the test. Engineering data from this test will be used to increase confidence for future GMD intercept missions. This test is designated Ground-based Midcourse Defense Controlled Test Vehicle-02+.

    The GMD element of the integrated BMDS provides Combatant Commanders the capability to engage and destroy limited intermediate- and long-range ballistic missile threats in space to protect the United States.

    Additional information about all elements of the Ballistic Missile Defense System can be found here.

    Ground-based Midcourse Defense (GMD)
    The Ground-based Midcourse Defense (GMD) element of the Ballistic Missile Defense System provides Combatant Commanders the capability to engage and destroy limited intermediate- and long-range ballistic missile threats in space to protect the United States.

    Overview
    • GMD employs integrated communications networks, fire control systems, globally deployed sensors and Ground-Based Interceptors that are capable of detecting, tracking and destroying ballistic missile threats.
    • The Exo-atmospheric Kill Vehicle (EKV) is a sensor/propulsion package that uses the kinetic energy from a direct hit to destroy the incoming target vehicle. This hit-to-kill technology has been proven in a number of successful flight tests, including three using Ground-Based Interceptors.
    Details
    • Ground-based Midcourse Defense is composed of Ground-Based Interceptors and Ground Support & Fire Control Systems components.
    • The Ground-Based Interceptor is a multi-stage, solid fuel booster with an EKV payload. When launched, the booster carries the EKV toward the target's predicted location in space. Once released from the booster, the EKV uses guidance data transmitted from Ground Support & Fire Control System components and on-board sensors to close with and destroy the target warhead. The impact is outside the Earth's atmosphere using only the kinetic force of the direct collision to destroy the target warhead.
    • Ground Support & Fire Control Systems consist of redundant fire control nodes, interceptor launch facilities, and a communications network. GMD Fire Control (GFC) receives data from satellites and ground based radar sources, then uses that data to task and support the intercept of target warheads using Ground-Based Interceptors. The GFC also provides the Command & Control, Battle Management & Communications element with data for situational awareness.
    Deployment
    • Ground-Based Interceptors are emplaced at Fort Greely, Alaska and Vandenberg Air Force Base, California. A total of 30 interceptors were deployed at the end of 2010.
    • Fire control, battle management, planning, tasking and threat analysis take place via a dual-node, human-in-control interface located in Fort Greely, Alaska and Colorado Springs, Colorado. Warfighters of the 49th Missile Defense Battalion at Fort Greely, Alaska and of the 100th Missile Defense Brigade at Colorado Springs, Colorado. operate the system.
    • All GMD components communicate through the GMD communications network, a secure data and voice communications system using SATCOM and fiber optic cabling for long-haul communications.

    VANDENBERG AIR FORCE BASE, Calif., Jan. 28, 2016 /PRNewswire/ -- A Raytheon Company (NYSE: RTN) Exoatmospheric Kill Vehicle (EKV) successfully completed a data-gathering mission during a Missile Defense Agency flight test. The mission's objective was to observe in-flight performance of redesigned components and gain valuable information on evolving threat classes.

    EKVs are designed to destroy incoming ballistic threats while they are still in space. As part of the MDA test of the Ground-based Midcourse Defense system, a ballistic missile target was launched and purposely not intercepted to demonstrate for maximum maneuvering and data collection.

    I think with terminal defense you only have 20 km area where the ballistic missile threat is intercepted. I think with the mid course interception it is longer interception range?

    Maybe a stupid question, why do you need this system if you have aegis ashore?

    Aegis Ashore uses a smaller midcourse interceptor that can't intercept any Heavy ICBMs like GMD can.

    But the drawback is that GMD requires expensive infrastructure like silos, and is much more expensive per missile:

    Here is the the missile Aegis Ashore uses as of now, the RIM-161C SM-3 Block IB, from Mk.41 VLS:

    and here is GMD:

    As you can see, the size difference is pretty large

    Holy ****!!! That's huge!

    Are there any specs for GBI? Speed, range, altitude, anything?

    [​IMG]

    The GBI was designed for exo-atmospheric interception of ICBM class targets, so it's got to have a massive range - especially as mid-course is actually in the name, mid-course being before warhead separation.

    I couldn't find a solid spec for altitude, but I did find one for its closing intercept speed, roughly 10km/s

    Well, there are no solid specs I could find on the range , so I turned to looking at some of the intercept tests.

    The FTG-06b flight test looks like it made it from California to about 1000 km directly north of Hawaii, so I did some Google Earth ranging and its seems that, for that particular flight test, it traveled about 3500km. Whether it could go more than that I have no clue. But that is still pretty insane.

    Add the Multi-object Kill Vehicle to that mix in the future, and it looks like GBI is shaping up to become a game changer against mass ballistic missile raids.

    I watched this video that explains air and ballistic missile defence and thought I knew everything.



    GMD = Long Range Interception
