Not really much better but anyway a clear sign for "there is at least something out there" !

It isn't supersonic. It's too short. It would have serious wave drag issues and control issues.totoro said:now that i think of it, some other ucav demonstrators have afterburning engines installed but no one talked about their potential supersonic use.

totoro said:i have no idea if the aircraft is supersonic. but i am wondering what do non-afterburning engines used in combat planes look like? how do their nozzles look? does anyone have some images? (the ones i managed to google are quite small and not detailed, but it seems such engines don't really have nozzles like this, but have simpler nozzles)
IF the engine is afterburning one, it wouldn't be a simple switch to non afterburning one. we're talking a 1 to 1,5 meter longer/shorter engine, a few hundred kilos more/less and center of gravity of the whole plane being pushed back, compared to plane with a non-afterburning engine.
pretty much all planes are designed around the engine requirements. some planes did have different variants of engines installed but i can't think of many (any?) examples where nonafterburning engine was switched for an afterburning one, let alone vice-versa. Can someone list a few of such examples?
Afterburner, subsonic: North American F-86D, Lockheed F-94C. This is just from memory, there might be more examples.totoro said:so what other aircraft, demonstrators or not, have ever been installed with afterburner but were not capable of supersonic flight? and what other aircraft had, at any point during their lifetime, changed their engines from afterburning one to a non afterburning one?

On another question, isn't the Sharp Sword suitable for both land and carrier operations?
I think YES ! At least YOU seem to be.don't have them on video stealing CATIA files we've sunk to the level of Kemag when it's as obvious as the sky is blue? Okay. . .
chuck4 said:Leaving the charming digression about whether it speaks well or ill of the chinese to avail themselves of good defence ideas where they find them (Speaks very well of the right sort of hubris that doesn't go to their heads, unlike the wrong sort sometimes exhibited on this board, IMHO), I just like to ask why does the engine nozzle on that drone look like it is in full open, after burner position if it is only capable of dry thrust?
