No, they aren't. The original Su-27 flanker was a dedicated air superiority aircraft. The Su-30 was a multirole strike fighter, and the MKI is the same thing with better avionics and slightly better air-to-air performance.
They are our best strike aircraft, comparable to the F-15 strike eagle. They can pound the ground harder than any other aircraft we have.
From wiki, these are the ground pounding weapons it can carry:
Air-to-surface Missiles:
3 × Kh-59ME TV guided standoff Missile, 115 km
3 × Kh-59MK active radar homing anti-ship missile, 285 km
4 × Kh-35 anti-ship missile, 130 km
1 × Brahmos supersonic cruise missile, 300 km
1 × Nirbhay subsonic cruise missile, 1,000 km
6 × Kh-31P/A anti-radar missile, 70 km
6 × Kh-29T/L laser-guided missile, 30 km
4 × S-8 rocket pods (80 unguided rockets)
4 × S-13 rocket pods (20 unguided rockets)
Bombs:
8 × KAB-500L laser-guided bombs
3 × KAB-1500L laser-guided bombs
8 × FAB-500T dumb bombs
28 × OFAB-250-270 dumb bombs
32 × OFAB-100-120 dumb bombs
8 × RBK-500 cluster bombs
Name one aircraft in the IAF that has more ground pounding ability. They can carry more ground pounding weapons than any other aircraft, to far greater distances than any other aircraft. Heck, there are only two or three in the world that can carry as much ground pounding munitions as the MKI. They are our best air superiority fighter, and our best striker - in other words, our best multirole fighter.
Depends on which weapons the IAF has specifically ordered
If deagel is to be believed.. then India has chosen the Israeli Crystal Maze weapon system(based on the popeye).. for an unknown platform(quite likely the MKI)
The KH-27PS anti-radiation missile is also listed.
Other weapons may be operational but it is unlikely that the MKI carries all of the loads specified(it probably carries some unspecified)
