Hi,
I found in Wikipedia that SU-27 specification is superior than SU-30 especially for speed, rate of climb and range

However..many countries have SU-30 than SU-27.

What's the advantage from SU-30 than SU-27?

spec from wiki..

When you are refering to Su-27 i take it you mean Su-27SM which is the Russian designation for Small upgrade program.
Cause the Su-27S/SK are hopeless outdated in term of avionics, engine too.
I think this has been up for debate several time here, have you tried to search for any topic?


There are some difference in the KNAPPO & IRKUT plant produced Su-30 exported to various countries.
Most of them use third countries equipment/systems like Israel, France, South-Afrika.

While the Su-27 uses Russian made systems only.
Well, i think Russia use some Thale target pods these days but you get the picture.

The Russian Su-27SM use a AL-31FM1 engine delivered from MMBPP Salut which rate close to 13.500kgf, a little more vs the AL-31F the Su-30 export version use..
The Su-27SM have less drag and more internal fuel vs Su-30.(singel crew vs two crew station!)
The Radar some of the Su-30 use have some extra features and mode vs Su-27SM.
The 2 crew station Flanker like Su-30 can sometime prove to make a difference in handeling search & target from radar more effective. The weapon system crew station do ease the amount of work load from the pilot.

Well.. there are many small difference here and there, but i'm not sure whos got the most capable Flanker.


Thanks

No. SM is not small upgrade. S is serial. Like Mig-29S and Su-27S. M is modernized. That's how you can have Su-27SKM. ;)

Also from what I understand the SM features don't include a new radar or major avionics upgrades. So in essence it's a renovated, and slightly upgraded Su-27S. It's definetly less capable then the MKI, MKM, or MKA. Probably less capable then the MK2, MKK and MKV.

Speed alone doesnt a better fighter make

Check out the Mig-25 and the Mig-31

I have my doubts that the "S" stands die "Serial" in the case of the MiG-29 as the original 9.12 & 9.13 had no "S" attached. The MiG-29S is a modified version originally based on the 9.13 and therefore 9.13S, but 9.12 derived variants were developed as well.

The Su-27SM should be compareable to the Su-30MKK/MK2 as it was developed on base of its technology. What I find curious are the claims about a new digital FBW and AL-31FM engines as stated by Piotr Butowski in an article. Definite features include the N001V radar, OLS-30, upgraded glass cockpit similar to that of the MKK front cockpit, new navigation and radio systems, possibly IFF and new SUV to support new weapons including smart AG munitions.

Capability to use guided munitions. I don't know that the two SM regiments have actually received any. Or that any new guided munitions have been developed and introduced recently. Otherwise yes the upgrades are roughly what you listed. Glass cockpit, GLONASS nav., OLS, and better comms. Marginal upgrades.

Well that the units haven't received AG weapons is another topic. But what do you expect from such an upgrade? An entirely new aircraft?

Something a little more impressive then basically an electronics upgrade. What I'm trying to get across here is that this isn't as much of an upgrade as it is a refurbishing of the fighter jets so that after 15-20 years of neglect they can be operational again.

Here is the different cockpit layout in the Su-27S & Su-27SM.
