There is a difference between road mobile and air transportable.  For the size missile in question if you work the numbers you'll see that the vehicle weight increases significantly if you require it to absorb the loads attributable to the jet efflux or even gas generator developed thrust at launch. You need mass to resist that force and provide a stable launch platform thanks to a gent named Newton.  A TEL for this size missile could very well be too large and heavy to transport in a C-17.  Making it transportable allows you to use the vehicle to erect the launch tube (I'm assuming a gas generator cold launch) and move away after suitable bracing is installed.  We're talking hours not days but certainly more than minutes of a mobile system.  The C-17 can get into short runways much like a C-130 opening up a lot more potential launch sites.  So if you want to protect Hawaii, Guam, or our Allies in the Pacific or elsewhere as long as you have radar covering the enemy's launch sites you got a system that can protect them.

Transportable?

Homeland Missile Defense System Successfully Intercepts ICBM Target
17-NEWS-0003
May 30, 2017

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 successfully intercepted an intercontinental ballistic missile target during a test of the Ground-based Midcourse Defense (GMD) element of the nation's ballistic missile defense system.

This was the first live-fire test event against an ICBM-class target for GMD and the U.S. ballistic missile defense system.

During the test, an ICBM-class target was launched from the Reagan Test Site on Kwajalein Atoll in the Republic of the Marshall Islands. Multiple sensors provided target acquisition and tracking data to the Command, Control, Battle Management and Communication (C2BMC) system. The Sea-Based X-band radar, positioned in the Pacific Ocean, also acquired and tracked the target. The GMD system received the target tracking data and developed a fire control solution to intercept the target.

A ground-based interceptor was launched from Vandenberg Air Force Base, California, and its exo-atmospheric kill vehicle intercepted and destroyed the target in a direct collision.

"The intercept of a complex, threat-representative ICBM target is an incredible accomplishment for the GMD system and a critical milestone for
this program," said MDA Director Vice Adm. Jim Syring. "This system is vitally important to the defense of our homeland, and this test demonstrates that we have a capable, credible deterrent against a very real threat. I am incredibly proud of the warfighters who executed this test and who operate this system every day."

Initial indications are that the test met its primary objective, but program officials will continue to evaluate system performance based upon telemetry and other data obtained during the test.

The test, designated Flight Test Ground-Based Interceptor (FTG)-15, will provide the data necessary to assess the performance of the GMD system and provide enhanced homeland defense capabilities.

The GMD element of the ballistic missile defense system provides combatant commanders the capability to engage and destroy intermediate and long-range ballistic missile threats to protect the U.S. The mission of the Missile Defense Agency is to develop and deploy a layered ballistic missile defense system to defend the United States, its deployed forces, allies and friends from limited ballistic missile attacks of all ranges in all phases of flight.

Additional information about all elements of the ballistic missile defense system can be found at www.mda.mil.

Hopefully, they'll post images of Orbital ATK's ICBM target.

What distinguishes a "live fire" test from the previous intercepts?  For Aegis/THAAD, they have launched targets without notification to the interceptor crew so they had to rely upon detection and identification on their own.  However, I haven't seen that defined as "live fire".

The sole imperative of a government, once instituted, is to survive.

As far as I'm concerned - yes to both. Perspective. Thanks, GH.

Video of intercept.  I wonder if presidential release authority is required in an actual event.

At the moment, I would hope not.
