On this infographic you can see potential evolution for Russian PAK-FA T-50 stealth multi-role fighter fifth generation, which will receive code Su-50, when production line starts serial production. Plan for serial production was on January 2016, and will fly under flags of Russia, South Korea, India and Iran.
There are already 5 prototypes.
Sukhoi wants to start producing of special version for Indian Air Force (IAF), which will gets code Su-50E.
If ever South Korean choose to buy Su-50 as their new fighter, they will getting version with local avionics, and jet will get code Su-50EK.
Su-50E have chance to get brother twin seat version co-developed with India for IAF around 2020. year.
In the same year, Sukhoi plans to share with the world Su-55-FGFAM, modernized version of twin seater.
At the end, around 2022. year Iranians are planning to get their Su-50ES version (if ever)
In total 17 Su-27M aircraft were built by Sukhoi and KnAAPO; five prototypes converted from Su-27s, two static test airframes, six pre-production test aircraft, three production aircraft, and one Su-35UB prototype. Although the Su-35 (Su-27M) had no success on the global fighter market, the Su-27M line greatly contributed to the development of the Flanker family, both in terms of aerodynamics and avionics. The Su-27M saw the introduction of canards and 3D fly-by-wire control for enhanced manoeuvrability. The final two preproduction aircraft T10M-11 and T10M-12 (bort numbers 711 and 712) tested the N011M phased-array radar. Aircraft ‘711’ went on to become the Su-37 Terminator and was soon after converted to thrust vector control (TVC) demonstrator, fitted with AL-31FU and modified FBW system

Corporation Irkut was established 2002.y based on Irkutsk Aircraft Production Association. Integration was into the corporate structure of JSC “Yakovlev Design Bureau Yakovlev “to ensure the expansion of the production and the development of the Corporation.
There are production, assembling and development center for Su-30SM, Su-30MK, Yak-130, and more and more aeronautical and aerospace engineering and production subjects.
The plant has manufactured nearly 7000 aircraft of more than 20 types since 1934, which were delivered to 40 countries.
In addition, the plant has launched a new assembly line for civil aircraft manufacture where production of the MC-21 family of airliners is organized.
