U.S. Missile Defense Agency conducted a successful non-intercept flight test of the Ground-based Midcourse Defense (GMD) element of the nation’s Ballistic Missile Defense System (BMDS) on Thursday.

The mission's objective was to observe in-flight performance of redesigned components and gain valuable information on evolving threat classes.The test objective precluded an intercept in order to collect engineering data that’s not possible in an intercept test.


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 Raytheon kill vehicle initiated a planned burn sequence to evaluate the alternate divert thrusters until fuel was exhausted, intentionally precluding an intercept.

The ballistic missile target was launched and purposely not intercepted to demonstrate for maximum maneuvering and data collection.

The successful mission proved the effectiveness of a recent redesign of the EKV thrusters, which provides the control necessary for lethal impact with incoming threats while safely outside of the Earth's atmosphere. 

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.

Raytheon is simultaneously managing four kill vehicle programs – the EKV, Standard Missile-3 kinetic vehicle, Redesigned Kill Vehicle, and Multi-Object Kill Vehicle. The Raytheon kill vehicle family has a combined record of more than 30 successful space intercepts.

The test was carried out 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.
