    What the hell is it and how does it work?
    I've heard it mentioned in conjunction with the F-35 but wondered how it worked

    The F-22 can do it aswell. Essentially is the ability to go supersonic without the use of afterburners. Allows for longer periods of time at supersonic speeds (and I assume will use less fuel as there are no afterburners in use).

    Yup. I believe the English Electric Lightning was the first aircraft to feature that.

    you advance the throttle as much as possible without going into afterburner or basically the ability to hit mach in level flight without a/b

    Plenty of older aircraft can do it, take this not particularly comprehensive list of aircraft capable of supercruising from wikipedia:

    * SR-71 Blackbird
    * Concorde
    * Tupolev Tu-144
    * English Electric Lightning
    * F-104 Starfighter
    * BAC TSR-2
    * Eurofighter Typhoon
    * F-16XL
    * F-14A+
    * F-22 Raptor
    * YF-23 Black Widow II
    * XB-70 Valkyrie
    * Dassault Rafale
    * F-4 Phantom II (Israeli "Super Phantom" variant)
    * Mikoyan-Gurevich MiG-25
    (B-58 could also supercruise apparently)

    This except from this article on the F-104 provides some interesting reading on the subject.
    Starfighter F-104
    *My note: MiG-25 is also similar in this respect of having more thrust than it can use for top speed, the engines being limited to Mach 2.8 at which point delicate throttle use is required because at that speed it is very easy for the engines to get carried away and overspeed, which happened in the case of the infamous Mach 3.2 MiG-25 over Israel.

    Mach 3.2 recorded? Wow, I didn´t know that.

    Yep, but its engines were trashed and it only sustained that speed for a short period.

    Only the P.1 and P.1A prototypes of the English Electric Lightning could super-cruise. The production Lightnings could not. The Lightning would, however, at some point during it's flight achieve a thrust-to-weight ratio equal to 1:1. But the F-15 was the first plane to achieve that on take-off, with full load.

    Basically, supercruise is the ability to go beyond the speed of sound in level flight without the use of afterburners. It's just a coined term for a fast plane!
