Look.
But I'm not sure this "SU-30"...
Some information said,SU-30KI is only one "one pilot SU-30"...
The SU-30KI was improved on SU-27,except payload Air-to-Air missiles,it can payload KH-31,KH-59 or other Air-to-Ground missiles...Just like SU-27SMK...:pilotfly:

"Su-27SKM is Seriyniy Kommercheskiy Modernizirovanniy - Serial Commercial Modernized - is the next version of Su-27SK -Seriyniy Kommercheskiy (Serial Commercial).
The main differences of Su-27SKM in front of basic Su-27 and Su-27SK are:
- 12 wing stations (instead of 10)
- maximum payload of 8000 kg (instead of 6000 kg) due to enforced gears
- upgraded navigation, aiming, communication equipment and active jamming device
- aerial refuelling system
- upgraded fuel flow system, wing and wing stations for two additional fuel tanks 2000 liters each
Su-27SKM is much cheaper then Su-35/37 but like these two was designed to work not only against aerial but ground targets too.
Su-27SMK is just letters position change in designation, nothing more.
Su-30KI is almost the same as Su-27SKM - its an upgraded version of Su-27SK with all the same upgrades (air refuel probe, 12 wing stations, 8000 kg of payload). The only difference - this plane was designed customly for the Indonesian Airforces. So it were some slight (not crytical) changes in avionics and different color scheme."
