    Success!

    With a smaller version. Mach 5-8, 4000km, hit the target. http://defense-update.com/20111117_s...n-concept.html

    That has more validity than you might imagine. The very reason Khrushchev support missile development was to avoid having to compete blow-per-blow with the US force projection infrastructure left after WWII. Later, he was removed and they tried a carrier, kept looking for a B-52 equivalent, and went broke.

    Even here, people are questioning the use of Carriers http://www.usni.org/magazines/procee...fluous-carrier

    With Iran very far from Israel, the Jericho missile looks to be an option. Stand-off weapons are really becoming more and more of a reality, and cheaper than operating many bases. What I want folks to help me understand is this: Why so much focus on some of the hypersonic airbreathing concepts eleswhere? I seem to remember an op-ed where folks praised the all solid skybolt over any of the new wave hypersonic missile concepts. All I have heard in the way of chatter was that Skybolt was TOO good.

    They deserve it.
    I know it seems silly to give anthromorphic traits to our robots, but I don't know of anyone who was a "fan" of the rovers who didn't do it. The comic is actually kind of sad.

    And yes, they do deserve it.

    UPDATE:

    Probable cause of the failure has been released.

    Skin-peeling speed doomed hypersonic glider, U.S. says
    "The most probable cause of the HTV-2 Flight 2 premature flight termination was unexpected aeroshell degradation," the research group explained in a new statement on the test flight.

    Translation: The unmanned glider was streaking through the atmosphere when its outer skin started to rip off the airframe.


    I got a chuckle at this comment:
    DARPA knew friction from the glider passing through the air so fast would cause it to heat up.
    Considering that's a given in aerodynamics, I would hope they know.
