Can you make a comparison of Su-30, Rafale and Mig-29K in terms of RCS, practical weapons load, range with practical load, Type of weapons carried, Known capability of sensors etc. Please take only the capabilities which are available in already built planes, and not what is happening in labs.
I'll keep it simple.
RCS
Su-30 = ~12m2
Mig-29K = ~1m2
Rafale = ~0.1m2
Best ranges with tanks
Su-30 = 2500-3000Km (on internal)
Mig-29K = 3000 Km with three drop tanks
Rafale = 3700+ Km with three drop tanks (CFTs are available) Actual range in the region of 4500 Km with CFT.
Sensors:
Radar
Su-30 = Bars PESA - 130 Km for a 3m2 RCS
Bars Phase 1 - 200 Km for 3m2 (estimate)
Eventually be upgraded with Bars Phase 2 AESA. Estimate ~500 Km for 3m2.
Mig-29K = Zhuk-ME MS - 120 Km for a 5m2
Rafale RBE-2AA AESA - 200+ Km for 3m2
EW suite
Su-30 = Tarang Mk3 RWR + Israelis EL/L 8222 jammer (Ancient now)
Mig-29K = Same
Rafale = Spectra AESA EW suite, GaAs. Currently flying with GaN on a test bed.
IRST/Cam
Su-30 - OLS-30 - 90 Km against aerial target - 2 color system (You just see dots)
Mig-29K - OLS-29 - 90 Km against aerial target - 2 color system
Rafale - FSO - 130 Km against aerial target - QWIP (Creates a visual image of the entire target, hence target can be attacked at sensitive regions, like the cockpit, instead of just chasing engine heat)
TV Camera is also available and works at great ranges. Zoom functions available that give the Rafale a visual hawk-eye. So the pilot can actually see the target at 50+Km ranges.
MAWS/LWS
Su-30 = None
Mig-29K = None
Rafale = DDM - 4 sensors around the aircraft meant to pick up missiles and other aerial targets
There are much more subtle differences that come up when you do a system vs system comparison. Apart from the fact that Rafale's sensors suite is more advanced, it can also perform multiple functions at once. And some capabilities are far in excess compared to the other two. Like, when it comes to ground attack, the RBE-2 PESA alone can attack 6 targets on the ground at once while also engaging a bunch of targets in the air. The AESA version's capabilities are classified. Su-30 and Mig-29K can only attack two targets on the ground at once and none in the air at the same time.
Due to networking and fusion of sensors, other assets can also monitor Rafale's attacks. A soldier on the ground can watch the real time destruction of a target instead of waiting for confirmation later. Top brass can be watching the same at HQ.
Sensor fusion
Su-30 = None
Mig-29K = None
Rafale = The best available today. All sensors complement each other.
Weapons and payloads are similar with the exception that European weapons are currently more advanced in many ways, like QWIP seekers in IR seekers than the crappy two band system on R-73/74. Rafale beats both Su-30 and Mig-29K in terms of range. Rafale beats Mig-29K in terms of payload.
