Rvv-SD,
Excellent range, all aspect AAM, under intense electronic counter measure, folding fins ability to be carried internally
Problem is that the baseline is still untested in combat.
So you dont have a gauging point... looks better on paper(possibly not better than the SD-10B on paper.. but again.. on paper ).
Like the AIM-7Q.. supposed to be a dual seeker, redesigned version of the Sparrow..
but was cancelled because the Aim-120 did better.. and the sparrow's existing appaling performance records had people wondering how much could you actually get out of the system.
Probably why the R-27 is not taken in high regard either..
I had a discussion a while back with a USAF pilot I used to know(callsign "sideshow") who was a F-15 jock and last on A-10's(but that was five years or more ago).. Apparently the US had along with its aircraft evaluation programs.. acquired Russian missile systems as recent as the Latest Alamo(1999-2004) and Archer variants.. and was only impressed with the latter.
The Alamo performed worse than the Sparrow M and P in tests.. both the Radar and IR versions.
