guys i am thinking about why not india go for su35bm which is better then su30
lets have a view

Developed from Sukhoi Su-35
The Sukhoi Su-35BM is a heavy class, long-range, multi-role fighter. It is an improved variant of the Su-27M/Su-35 and is considered to be 4++ generation by its manufacturer, Sukhoi.[1][4] The Su-35BM was unveiled at the MAKS-2007 airshow.
Development
Sukhoi began modernising the Su-35 in the mid-2000s to provide a 4.5 type generation fighter making use of current technologies.[1][5][6] The modernised Su-35 will be interim design until the fifth generation PAK FA (T-50) enters service.[1] The modernised Su-35 has been referred to as "Su-35BM" (Bolshaya Modernizatsiya - Big Modernization) by some sources,[7][8] but Sukhoi simply refers to the fighter as "Su-35".[1] The first modernised Su-35 was presented at the MAKS-2007 air show in August 2007. The new Su-35 version first flew on 19 February 2008.[1]
The new design has a reinforced airframe for longer service life and has a reduced radar signature from the front.[1] The Su-35BM's new nose holds an improved passive electronically scanned array radar and the aircraft featured many other upgrades to its avionics and electronic systems, including digital fly-by-wire and a rear-looking radar for firing Semi-Active Radar missiles. In the 1990s, a two-dimensional asymmetric thrust vectoring system was first tested on the Su-35 and served as a basis for further development of the Su-37. For the modernised Su-35, a new type of 2D thrust vectoring engine, the 117S, has been developed and replaces the current AL-31F or AL-35.[9]

The cockpit has been redesigned with two LCD screens and compatibility with helmet-mounted displays. The Su-35BM's software has added compatibility with new weapons systems. Other new avionics include a long-range information targeting and jam-resistant datalink capability and an electronic reconnaissance system. Newer, lighter systems have been added (including a brand new FBO (Fly by Optics) flight-control system and OLS). The avionics are integrated with the GLONASS radio-based satellite navigation system.Flight testing and seeking orders
On 14 April 2009 one Su-35BM prototype fighter crashed during a high speed ground test. The test pilot escaped unharmed after ejecting.[10] According to Sukhoi, the fighter's brakes failed during landing, resulting in the speeding plane going off the runway and the left engine catching fire.[11]
In July 2008, Russia has offered the Su-35 for sale to India,[12] Malaysia and Algeria.[13] The Brazilian Air Force,[14] Vietnam People's Air Force[citation needed] and Venezuelan Air Force[15][16] have expressed interest in purchasing Su-35s to replace their older fighters.
The Su-35BM was demonstrated at Maks 2009, on 18 August 2009. Also at this show, the Russian Air Force signed a contract for the delivery of 48 Su-35S fighters by 2015, along with 12 Su-27SM and four Su-30M2 fighters, representing the first production order for the Su-35.[17][18] In November 2009 Sukhoi started implementing the state contract and the assembly of the first serial planes is scheduled for 2010.[19]
The Su-35 is participating in Brazil's F-X2 contest. Anatoly Isaikin, general director of Rosoboronexport, declared on 6 October 2009 that the company will provide 120 fighters and a full transfer of technology.[20] Libya is expected to sign a contract for the purchase of 12 Su-35 fighters by end of 2010.[21]
[edit] Design
Contrary to the designs of the original Su-35 and Sukhoi's other recent machines - the Su-30MKI and the Su-37 - the new Su-35 omits the canard and speedbrake. The canards were needed to increase/maintain maneuverability due to the addition of more modern, and heavier hardware in the nose area, compared to the original Su-27. A disadvantage of the canards is they significantly increase radar returns and drag, thus decreasing efficiency, speed, range, and weapons-carrying capacity. The Su-35 uses composite materials and newer electronics to make the aircraft lighter, especially in the nose area. This allowed Sukhoi's designers to do away with the canards and their disadvantages while still keeping up high operational system characteristics. The lighter new design has actually allowed an increase in both fuel and weapons-carrying capacity as compared to earlier Su-27 fighters. To maintain maneuverability equal to or greater than canard-equipped fighters, the Su-35 uses fully-rotating vectoring thrust nozzles on its new powerful Saturn engines.[22]
This new airframe design also reduces its radar cross section.[23] The aircraft's engines have also been improved to the 117S and the air intakes are enlarged. A probe and drogue in-flight refueling system has been added as well.
Aside from its obvious physical differences, not only have the Su-35BM's avionics received significant improvements, but they are also entirely of Russian origin. The Su-35BM is equipped with an improved passive electronically scanned array N035 Irbis radar system, as well as additional rear mounted radar in its shortened tail sting, later production will use Irbis-E radar, an improved N035 with higher peak power and better ECM characteristic. An L175M Khibiny-M self-defense electronic countermeasures and electronic warfare system has also been installed, future production will include the new Irbis-E Radar with more powerful search ability. The Irbis-E radar has an average power output of 5 kW and a peak output of 20 kW. When the H035 radar was tested on Su-30MK No. 503, the detection range was as far as 290 kilometers with 1 kW power output.[9] The radar system can track up to 30 aerial targets and engage up to eight.[24] The radar has a diameter of 900 mm and scans electronically to 60 degrees Azimuth and Elevation and mechanical scanning increases the Azimuth coverage to 120 degrees. It has an air to air detection range of 90 km against a stealth aircraft target RCS of 0.01 m².[25]
