DARPA’s Falcon – the other prompt global striker

The internet has been abuzz with stories about a new US space weapons programme, all based on an erroneous report in the Washington Post about one of my favourite DARPA projects – the Falcon hypersonic cruise vehicle technology demonstrator.

Falcon has been around for yonks, but the Post managed to mangle the wording of the House-Senate conference report on the 2008 defence budget. This zeroed out the US Navy’s Conventional Trident Modification programme to convert nuclear missiles into precision bombers, but provided $100 million for a new Prompt Global Strike programme. The money came from CTM and the US Air Force’s Common Aero Vehicle project to develop a conventional-warhead ballistic missile re-entry vehicle – but is not going to Falcon, as the Post reported.

Falcon%20HCV%20global.jpgThere is a connection, of course. DARPA’s Falcon programme is developing technology for an unmanned hypersonic attacker able to strike anywhere in the world within 2 hours. But it has also sponsored work on small boosters – SpaceX’s Falcon I and AirLaunch’s QuickReach – that could launch the unpowered Falcon hypersonic technology demonstrators as well as the USAF’s CAV…or form the basis of a prompt global strike weapon.

But the Falcon programme has had as many changes of direction as Britney Spears has had lapses of dress code. The initial HTV-1 demonstrator was dropped after it proved unproducible. Now Falcon prime contractor Lockheed Martin is working on the more advanced HTV-2, which is planned to fly in 2008. The expendable HTV-2 will be launched by a rocket (Orbital Sciences’ Minotaur) to demonstrate aerodynamics and materials needed for sustained hypersonic cruise.

Meanwhile…Lockheed is designing the HTV-3X, a powered, reusable demonstrator that would be able to take off, accelerate to hypersonic speed, cruise at Mach 10, then return to a runway landing. The HTV-3X, to be renamed the Blackswift if DARPA secures funding for the demonstration in 2009, would be powered by turbojet/scramjet combined-cycle engines. To see how it’s supposed to work, check out this cool video (and, yes, engineers didn’t look like that when I was one…)

So, back to that Washington Post story. Rather than give the $100 million to Falcon, the Congressional conferees actually created a new conventional prompt global strike programme to look at things like propulsion and guidance systems, re-entry vehicles, command and control, intermediate-range missile concepts and advanced non-nuclear warheads. More realistic, maybe, but I’ll keep my fingers crossed for Falcon.

    What?… Why spend unnecessary millions or billions of dollars?!? Why doesn’t the gov’t/military just use the current technology they have in use in anti-gravity lift?
    Please don’t say that it doesn’t exist; because it is currently in use!

    There are things in the black world we can only guess at. But are they of use in a fight against terrorists?

    very interesting, but I don’t agree with you

    The other day, while I was at work, my sister stole my iphone and tested
    to see if it can survive a 30 foot drop, just so she can be
    a youtube sensation. My apple ipad is now broken and she has 83 views.

    I know this is entirely off topic but I had to
    share it with someone!

  5. Hi, yeah this paragraph is truly pleasant and I have learned
    lot of things from it concerning blogging. thanks.
