  • F-35 Breaks the Sound Barrier
    Posted by Graham Warwick 10:37 PM on Nov 13, 2008

    The Joint Strike Fighter has gone supersonic for the first time. The pre-production F-35, aircraft AA-1, reached Mach 1.05 during an hour-long flight from Lockheed Martin's Fort Worth plant earlier today (Nov. 13). A small, but significant milestone.

    It was AA-1's second flight of the day and the 69th since its maiden sortie on Dec. 15, 2006. Total flight time is just past the 95-hour mark - not a huge amount, but if anyone is plotting this out, the curve has been reasonably steep in the last few weeks.

    [UPDATE] LM says AA-1 completed four runs to Mach 1.05 for a total supersonic time of 8 minutes. The aircraft was also carrying a full 5,400 lb. internal load of (inert) weapons.

    Next up? The first flight with weapons bay doors open...
