The AX featured a dry Rolls-Royce-SNECMA M45 turbofan and a 15 degree swept wing.

The M45 engine family warrants an entire thread of its own right.

The source of the image seems to have been www.acfavi.hpg.ig.com.br, but the site now seems to be offline.

Thanks for posting ! ... and the page seems to be online again here:

http://www.acfavi.hpg.ig.com.br/ax.htm ... but as I understand the text it was the "Embraer A-X" not an italian project !?! ???

And there seems to have been another project; the Embraer AX-1:

... similar to the EMB-330:

PS: I saved the pictures of the AX-1 under the wrong name EMB-330 ... below it's the AX-1 !

Back in the 70s, I remember reading a report in the aviation press of a Macchi M.340 for the AX program. Supposedly, at that time it used two M45 engines in a configuration similar to the A-10's.

Forerunner of the AMX (Italian side) were two different albeit largely parallel project lines: the MB-340 I already extensively covered, and the MB-341. First was a rather simple CAS, second was a more advanced small strike aircraft, but in the end it evolved in a sort of two-engines AMX.
Original configuration on MB-341 I already posted here http://www.secretprojects.co.uk/forum/index.php/topic,629.msg8383.html#msg8383

Then there was a configuration with a different positiones canard (actually it was almost a coupled wing). Bombs would have to be stored in semi-conformal position.

Circa 1980, the MB-341 evolved in a slender configuration, with vertical fins mounted on the wings. Later, is became more conventional, with the MB-341B that was more tailored to a CAS mission.

By 1983, the MB-341 for CAS has come full circle and was now very similar to a two-engines MB-340. The final AMX was a blend of the two lines and the Embraer one with a single engine. It wasn't the end for the MB-341 line, which took an unexpected twist, with the "S" configurations, but on this another topic.... 8)

I have always been a strong believer in two-engine designs for the CAS role. I think the Italian's should have stuck to this in their AMX design

Yes, so thought Aermacchi. Problem was cost. Accepting one engine, Aermacchi proposed to use the RB-199 without afterburber, but again too costly... so the AMX was only barely useful a few years after introduction.

An interesting could-have-been from Flight in 1978

Delegations from Aeritalia and Aermacchi have visited Sweden to discuss possible collaboration on the AM.X
strike/trainer aircraft. The Swedish Defence Ministry has asked the Defence Material Command to prepare a
report by the end of this month (see Flight for July 29, page 336).

Edit: aha, already mentioned in the B3LA thread.
