    This is the first time I hear anyone claim that 2D-nozzles are optimized for supersonic performance. And I have serious doubts this is true. For me, the main reason to use 2D nozzles is low RCS as they have negative impact on engine thrust and aircraft's performance, in general.

      27 September 2012:
      Fuji T-7. Basic trainer.
      JASDF.

      Board of Audit of Japan warned maintenance cost overrun.
      In 2000 September, Fuji and Pilatus competed for T-7 programme.
      Fuji was lower bidder, and won contract to produce 49 T-7.
      Fuji subsidiary tasked with maintenance.

      From fiscal year 2003, maintenance cost total foreseen as 2.183 billion Yen for 17 years.
      Actually, until fiscal year 2010, maintence cost total was 1.825 billion Yen, or about 80%, after eight years.

                        So F-35 use a should-be cheap alternative jet engine that is actually hopeless at super-cruise and super-sonic performance, due to its very high by-pass ratio.
                        Actually some technology from the F-135 is being planned to be retrofitted to the F-119...So much for...Second, its not HOPELESS at supercruise because it is cheap and crap..it was not designed to be a supercruising engine...Had that been a requirment they could have just simply used the existing F-119 and not modify it...The F-135 is a sollution for the JSF which did not have Supercruise as a requirment, but wanted good range, strike from a single engined bird..

                        As far as 2d TVC, that was not a requirment either....

                          Clearly, the F-35 with the P & W F135 wasn't designed to operate at Super Cruise like the F-22. (i.e. Mach 1.5+) Yet, we know the F-35 has at least some capability to do so. One source claims Mach 1.2 for ~150 miles??? While other sources say in can maintain such speeds for longer periods. Nonetheless, the F-35 was designed to excel at Transonic Speeds where most aerial combat happens.

                            Here are the two statements
                            Can almost supercruise

                            The F-35 can't supercruise like the F-22 Raptor, but the test pilots have found that once they break the sound barrier,
                            supersonic speeds are easy to sustain.
                            "What we can do in our airplane is get above the Mach with afterburner,
                            and once you get it going ... you can definitely pull the throttle back quite a bit and still maintain supersonic,
                            so technically you're pretty much at very, very min[imum] afterburner while you're cruising,"
                            Griffiths said. "So it really does have very good acceleration capabilities up in the air."
                            --------------------------------------------------------------------------------------------------------------
                            Not supercruise in a technical sense

                            The F-35, while not technically a "supercruising" aircraft,
                            can maintain Mach 1.2 for a dash of 150 miles without using fuel-gulping afterburners.

                              and more power is just around the corner. As a matter of fact several sources claim the F135 is capable of a great deal more thrust. :diablo:

                                Japan already has bought Raytheon AIM-120 Amraams, so why is it spending 36 billion ($468 million) to upgrade about 60 F-2 fighters with the Mitsubishi Electric Corp. AAM-4B missile?"
                                Looks pretty much like Meteor, but with an AESA seeker.

                                  Most of the F-35 users will happily take that technology and increased thrust (around 5% in the short - med term) and use it get range, as all 3 varients fall short when compared to the original requirment..>I do not know how it would effect the transonic acceleration, but i doubt that it would still be stellar even with increased thrust from the engines...

                                        You can bet that Japan will want both missiles to be intergraded into JASDF F-35A's.
