Don't know how anyone else feels,  but yesterdays launch gave me a great deal of pride for many reasons.
 
The cam videos were excellent as well as the launch work etc.
 
For me its a launch to remember  ;)

Makes me wonder how many lives of front line troops that these systems have saved over the years, or conflicts avoided etc etc.

You'd better not go there, or this topic will go really wrong way really quickly.

FWIW, I understood from ULA's broadcast that the SBIRS/GEO constellation is part of a ballistic missile detection and tracking system.  I imagine that the IR telescopes could be used to track high altitude reconnaissance and/or bomber aircraft too, depending on their sensitivity.

During the first gulf war along with tracking scud launches it was reported widely that the DSP's where able to track Iraq jet afterburners.

It all depends on the engine exhaust temperature... More modern Turbo Fan powered jets do not produce a very hot exhaust so they are harder to track.
I come here for the articles, not the pictures !!!

De-classsified references for "Space-Based Early Warning: From MIDAS to DSP to SBIRS" By Jeffrey T. Richelson at http://www.gwu.edu/~nsarchiv/NSAEBB/NSAEBB235/20130108.html refer to DSP detecting Backfire bombers and detection of 4 aircraft crashes/shootdowns (page 7 of reference 39.)

new cobra judy radars tracked the launch...

Demonstrating exceptional dual-band radar capability

TEWKSBURY, Mass., April 2, 2013 /PRNewswire/ -- The Raytheon Company (NYSE: RTN)-led Cobra Judy Replacement (CJR) program surpassed expectations during its first tests against a live rocket launch on March 19. From approximately 100 miles off the Florida coast, the powerful X- and S-band radars integrated onboard the USNS Howard O. Lorenzen (T-AGM 25) successfully acquired and tracked both stages of an Atlas V rocket launched from Cape Canaveral and collected all associated data.

Why do you say that, it was a question asked in good faith not designed to cause some kind of issue?

SBIRS GEO-2 Achieves AFSPC Operational Acceptance

Posted 11/26/2013   Updated 11/26/2013

11/26/2013 - LOS ANGELES AIR FORCE BASE, Calif. -- The U.S. Air Force announced Nov. 25 that the second Space Based Infrared System Geosynchronous Earth Orbit satellite (GEO-2) has achieved Air Force Space Command Operational Acceptance. GEO-2 is part of the constellation that provides continuous missile warning for the U.S. and its allies.

The SBIRS GEO-2 spacecraft launched successfully from Cape Canaveral Air Force Station, Fla., March 19. The satellite was originally scheduled to enter the operational trial period 12 months after launch, but the program implemented a number of efficiencies based on GEO-1 lessons learned. As a result, the combined test team was able to improve on the original schedule by five months and GEO-2 entered its trial period  on Oct. 21 with no liens. Overall, the GEO-2 satellite's performance matches that of GEO-1 and in some cases exceeds it.

SBIRS delivers global, overhead, persistent, taskable 24/7 infrared surveillance capabilities to meet 21st-century demands for early warning of missile launches, while simultaneously supporting other critical missions including missile defense, technical intelligence, and battlespace awareness. The GEO satellites replace and improve upon the legacy Defense Support Program satellites, offering enhanced sensor flexibility and sensitivity.

The SBIRS development team is led by the Infrared Space Systems Directorate at the U.S. Air Force Space and Missile Systems Center, Los Angeles Air Force Base, Calif. Lockheed Martin Space Systems Company, Sunnyvale, Calif., is the SBIRS prime contractor, Northrop Grumman Electronic Systems, Azusa, Calif., is the payload integrator. The 460th Space Wing operates the SBIRS system.
