Over here neither there is numerical superiority, nor there is an air to air superiority---an su 30 can carry 8 bvr's---the jf 17 can only carry 2---an su 30 can see and act from a farther distance with immunity
The JF-17 has 7 hardpoints - so why only carry 2 BVR's???
You must be thinking about the fire-control radar only being able to engage 2 targets.
The su 30's bvr's have a better killing range than the sd 10---it can get closer into the 90% killing range and fire multiple missile at the same target before the jf 17 can get within the 90% kill range of the sd 10---the su 30 can then turn around and scoot---the jf 17 may not even have the chance to fire at 90 % kill range.
In a similiar manner---the Su 30 mkI has bvr's that have a longer range than the future sd 10 of paf.
Tha max range of the russian bvr is around 100 km---the max range of sd 10 is around 60 km----the 90 % kill range of russian bvr is around 50--60 km---the 90% kill range of sd 10 is around 30 to 40 km if it is.
I seen many different figures for the performance specs of these missles on the internet that I don't know which to believe.
One site (Sinodefence) has the following figures for PL12/SD-10 and R-77. Chinese use both of these so I would probably say that these are more credible.
PL-12/SD-10:
Max speed: Mach 4
Max range: 50~70km
G Limit: 38g
R-77:
Max speed: Mach 3
Max range: 50~80km
G Limit: 12g
So if this data is correct, then both missiles seem to be fairly even. The R-77 does have slightly more range but the SD-10 is faster and more agile.
As for radars:
I've seen figures for the KLJ-7 as 75km for a target of 3m2 - this would obviously increase for a target as large as an MKI.
Assume MKI RCS ~15m2,
Using
Situation Awareness equation (RCS1/RCS2)^0.25......
JF-17 could detect MKI at 112km.
Conversely,
I've seen figures for the NIIP N011M Bars as 140-160km for a F-16 sized target.
The question now is "which F-16?" - Older ones are about 5m2, modern ones are around 1m2.
Assume it's 5m2 (since that's what Russians usually use anyway)
Also, assume JF-17 RCS is 1-2m2
Using same equation above.....
MKI could detect JF-17 at between 107-127km.
So radar detection is about roughly equal given their different sizes and become less relevant when AWACS/AEW is used.
