Su-27SM vs Su-30SM and Su-30M2 Differences

medo wrote:Su-27SM2 is more comparable with Su-30M2, because they both have similar engines without TVC and similar mechanical radars. Su-30SM is more comparable with Su-35, because they have both stronger engines with TVC and more powerful PESA radars (BARS and IRBIS) as well as more modern electronics.

But all those flankers are multirole fighters.

Domestic Su-35 is called Su-35.
Su-27SM2 is the designation for the 12 airframes delivered from Komsomoslk, that along with the 4 Su-30M2, are analogues to the Su-27SM upgrade fielded by the RuAF. There are some cockpit and equipment changes, but largely they are the same.
They are both not nearly as sophisticated in equipment as Irkut's Su-30s or the Su-35.

Su-35 Airplane to Be in Demand in Domestic and Export Markets

The Su-35 (Su-27SM2) fighter, which the Sukhoy OKB is developing, will be in demand not only by the Russian air force, but also by foreign customers, the general director of the Sukhoy Aviation Holding Company, Mikhail Pogosyan, has declared.

“We thing that the new airplane should be produced for the Russian air force in the Su-27SM2 “technical aspect.” Work in this direction is underway actively, inasmuch as the aircraft will be in demand both in Russia and abroad,” M. Pogosyan told Interfax-AVN.

According to him, “the need for replacement in the future of the existing fleet of Su-27 type fighters will require marketing in the period approximately of 2009 – 2010 along with the upgrade and overhauls and the order of new airplanes for the Russian air force.”

M. Pogosyan noted that in the draft of the Russia’s state arms program to 2015, all emphasis will be arranged neatly on the developments and purchases of aviation equipment, based on the volumes of financing.

“The Su-27SM2 is the next stage with a transition to new sensors and phased antenna array of the aircraft radar (RLS),” the Sukhoy AkhK general director emphasized.

In the opinions of specialists, the Su-27SM2 fighter, which is intended for Russia’s air force (the export variant is the Su-35) is a heavy upgrade of the Su-27/27SM fighters. The installation on the fighter of new aircraft engines with a thrust up to 14 tonnes (instead of 12.5 tonnes) and new aircraft equipment, including the “Irbis” aircraft radar, will be a distinguishing feature of the Su-27SM2. The fighter also is supposed to receive new long-range missiles of a different class.

It is planned that the Su-27SM2 will be a step in the creation of the future tactical aviation aircraft complex, inasmuch as on it many proposals for the fifth generation combat airplane will be perfected, Interfax notes.

The Sukhoi company can name their planes anything they like, but the official names come from the Russian military and Su-27S, Su-27P indicate fighterbomber and interceptor models of the Su-27. The S model has air to air and air to ground capability while the P models were for the PVO and had no air to ground capability at all... even dumb rockets and dumb bombs.

Electronics and IFF systems are different for frontal aviation and PVO aircraft.

The Su-27SM was a modest upgrade that was a cheap and simple way to improve the in service Flankers from fairly basic to fairly good multi role aircraft. The Su-33 was like the original Su-27 with R-27 andR-27E capability and R-73 for air to air, while air to ground was dumb bombs and rockets, the only upgrade over the bog standard Su-27 was the introduction of the Kh-31 missile in the anti ship version. Even the Mig-29C was more sophisticated than eitehr in service Flanker as it could carry R-77s. The Russian AF didn't actually buy any R-77s for operational use, but if they did the Mig-29C was the only aircraft that could carry and use it that they had in operational numbers.

The Su-27SM upgrades are the equivalent of the Mig-29SMT upgrades in that they were simple improvements that made the aircraft much more potent and capable at minimum costs and could be done relatively quickly... which was a good way of improving the general performance of the AF without having to wait years for new planes to be produced.

At the end of the day the comparison between Su-27SM2 and Su-30SM is that the latter has two seats.

TR1 wrote:You are confusing different variants from different plants.

The Su-30SM is from the Irkut plant, where the Su-30MKI originates from. IT has canards and TVC.

The Su-30MK is built at Komsomolsk, where they also build Su-35s now. The Su-30M2 is basically a domestic MK, has no carads, and no electronically scanned array.

We don't know the exact differences from the Su-27SM2 to the Su-27SM, but it is certainly not as advanced as the Su-30SM.

I do not see any difference apart from the Su-30SM with double wheels and Canard. Load of weapons and they do not have specific information, but I'm sure are in the range of 8 tons of Flanker family. Or if there is a difference, it can only be located in the avionics and radar aircraft

So the Russians are up to 4 choices?MiG-35 vs MiG-29SMT and Su-27SM vs Su-30SM?!
