Something failed shortly after launch from Kodiak today, August 25.  I'm not quite sure what launch vehicle was used.  It was aimed toward Kwajalein and was a test for the Conventional Prompt Global Strike program.  There was talk in the past about using retired ICBM or SLBM missiles or motors for such tests.  Could this have been a Minotaur-something?

Odd to see the X-37B classed as a hypersonic weapon in that first article.

That's what I meant it lumped the X-37B in with the X-51 & HTV-2 which makes no sense to me as how is a mini shuttle vehicle anything like them.

Here are some eyewitness accounts of the explosion at Kodiak.  There's a photo on the second page.
http://www.kmxt.org/index.php?option=com_content&task=view&id=5997&Itemid=2

Here is another report with a bigger photo.  It says that the Range Safety destruct was transmitted at only T+4 seconds.  It also reports that launch facilities suffered damage of an unknown extent.  According to this report it was the first launch failure ever at Kodiak Launch Complex, but I don't believe that is correct.

It was a STARS-IV booster (modified Polaris-A3) with an US ARMY AHW (Advanced Hypersonic Weapon) hypersonic glide vehicle test.

Expanded statement from a OSD spokeswoman.

Quote
OSD spokeswoman Maureen Schumann could not shed light on what went wrong with the test. The intended objective was to collect data on the glide vehicle during long-range atmospheric flight and to test and develop hypersonic glide capability, she said. The CPGS program is event driven, with the results of each test informing future experimental flights. Schumann said the results of the investigation would inform the programme's schedule moving forward.

“Program officials are conducting an extensive investigation to determine the cause of the flight anomaly,” the statement said.

Look like a fair amount of damage was done to the launch facilities. Here's a photo that is from reddit

And a short Video of the damage to the KLC. It also shows, that it is sensible to have a little more spacing between the launch pads.

According to this report it was the first launch failure ever at Kodiak Launch Complex, but I don't believe that is correct.

This is indeed not correct:

On 9 November 2001 the first STARS mission from Kodiak failed (West Coast Risk-Reduction Flight)

On 25 May 2007 another STARS target mission failed (FTG-03 Target)

But in both cases, the failure happened later in the flight, so no damage to the KLC facilities happened.

Advanced hypersonic weapon destroyed during U.S. test

Program aims to develop weapon that can destroy targets anywhere on Earth within an hour of approval

A hypersonic weapon being developed by the U.S. military was destroyed four seconds after its launch from a test range in Alaska early on Monday after controllers detected a problem with the aircraft, the Pentagon said.

IMMEDIATE RELEASE

Release No: NR-444-14
August 25, 2014

 
Advanced Hypersonic Weapon Test Conducted


Shortly after 4 a.m. EDT, the U.S. Army Space and Missile Defense Command/Army Forces Strategic Command, as part of the Defense Department's Conventional Prompt Global Strike technology development program, conducted a flight test of the Advanced Hypersonic Weapon from the Kodiak Launch Complex in Alaska.

Due to an anomaly, the test was terminated near the launch pad shortly after lift-off to ensure public safety. There were no injuries to any personnel.

Program officials are conducting an extensive investigation to determine the cause of the flight anomaly.

News media point of contact is Ms. Maureen Schumann, Office of the Secretary of Defense for Public Affairs, at 703-697-4162, [email protected]

This is all over the news in Alaska. The pad has extensive damage, no scheduled launches in the future, and little legislative support. I fear the end of the Kodiak complex

My immediate thought was that this is going to be a setback to Athena, which used LP1, the bigger tower that seems to have taken a hit.  I think that STARS would have launched from LP2, which is the small square pad near the lower horizontal building. 

However, when looking at satellite images I noticed for the first time that a new facility seems to be under construction just north of this site.  That may be a motor storage facility rather than a new pad, however.

One thing I haven't managed to find is what the diff is between STARS and STARS-IV  - any idea?

Already discussed since yesterday in the suborbital thread.

Then post a link to it

Edit/Lar: Suborbital thread posts brought over to this new thread. if you see any I moved in error, please report to mod or PM me. Thanks.

This failure appears to have taken out both launch pads at Kodiak in one fell swoop, presumably rising from LP2 and falling back near LP1, damaging both, though there is a chance that the launch was from LP1 based on the position of the RSS.  Lockheed Martin's Athena was supposed to launch from LP1 next year.

According to the following, the rocket did a 180 flip not far above ground.

What would be quicker - Fix Kodiak or modify one of the ICBM/SLBM launch complexes at Vandenberg?

In spite of this failure the program does appear to have future.

Quote
Congress has generally been supportive of the effort and, following its initial success, encouraged the second AHW test in its fiscal year 2014 defence appropriations bill.

Nonetheless, 'early termination' of test flights has been common in the nascent hypersonics field. The USAF and DARPA's HTV-2 suffered issues in both of its tests; although the agency has said it was pleased with the amount of data collected in the 2010 and 2011 flights.

DARPA noted that in order to fly anywhere in the world in less than 60 minutes, the system must travel at least 13,000 mph and withstand temperatures greater than 3,500 Fahrenheit (1,927 Celsius), both of which are significant design challenges.

Pentagon officials are hoping CPGS weapons can diversify military deterrence by developing a non-nuclear weapon that would allow the United States to accurately engage a target anywhere on Earth in under an hour, and ultimately the DoD hopes the CPGS programme results in either a sea-, air-, or ground-launched system.

STARS-IV has an extended skirt with grid stabilizers.
