Widely reported where?

This is going to sound like a copout but I read a LOT. It could have
been any number of places but I know I've seen it numerous times and I
RARELY rely on company propaganda for information. Usually company
sites are good for photos or videos (except for the exceptionally lame
Northrop Grumman site).




If you look at the Raytheon site
http://www.raytheon.com/products/aim9_x/ you'll see that the canard
configuration is similar to the AIM-9M.

The canards are much smaller and fixed.



Some
improvement in range is possible. Much higher is questionable. ASRAAM
and Python have much larger motors for the same generation seeker
technology (same seeker in ASRAAMs case) indicating that designers not
tied to a large stock of existing ordnance feel that more impulse can
be usefully employed exploiting the seeker's performance.

IIRC all the rest of the entries for which the -9x as-is was selected
had bigger motors too.
